This study aims to develop a short but valid and reliable instrument for the examination of student accommodation preferences. This study draws upon the instrument developed by Khozaei et al. (2011), the student accommodation preferences index (SAPI). The construct validity of the instrument was assessed through an exploratory factor analysis using a principal components Keywords: analysis with varimax rotation, by which 6 factors were extracted Instrument development; with 64 items. Because the questionnaire is lengthy, the current study Preferences; aimed to develop a valid and reliable shorter version of the Residence Hall; Validation; instrument to examine student accommodation preferences, thereby Exploratory factor analysis; extending the previous work by collecting data from a subsequent Confirmatory factor analysis. sample. The confirmatory factor analysis and subsequent iterative process yielded a valid and reliable student accommodation preferences instrument (SAPI) with only 29 items. This is much shorter than the original 60-item instrument. The iterative process was performed by considering good measurement theory and retaining at least 4 items per construct. This shorter revised instrument has been shown to be both valid and reliable.

1. Introduction The availability of student housing has been acknowledged as one of the major issues that students must consider when choosing a university. If universities are unable to provide housing for students, students face additional pressure, and the lack of affordable off-campus housing may become a significant problem. The result is that, in choosing between two similar universities, students may prioritize the university with available on-campus housing.

When students move far from home to attend university, they often need to minimize spending, and residence halls have been a proven means of achieving this goal. Consequently, many students prefer to reside in university residence halls. The issue of the affordability of residence halls aside, the profound impacts and benefits of residence halls on students must be considered. Because of the significance of these impacts, scholars have examined the influence of residence halls on students from various perspectives (Blimling, 1999; Cross et al., 2009). Some even studies have suggested that residence halls may influence students’ growth, behavior and academic performance (Araujo & Murray, 2010; Lanasa et al, 2007). Indeed, the crucial influence of residence halls might explain the numerous studies on college and university students’ lives, both on-campus and off-campus, over the last decades (Foubert et al., 1998; Rinn, 2004; Amole, 2005; Bekurs, 2007; Paine, 2007; Thomsen, 2007, 2008; Black, 2008; Cross et al. , 2009; Najib et al., 2011).

While the affordability of student housing is crucial for some students, for other students, comfort and home-like attributes are their main concerns. A recent study suggested that current students have significantly higher expectations for housing than their parents did when they were students, and students are willing to pay for certain amenities (Roche et al., 2010). Therefore, a distinctive feature of contemporary universities is the diversity of students and their needs and requirements. Thus, universities must provide students with housing that not only is affordable but also fulfills their requirements. Then the question arises, “What are the attributes of such a residence hall?” There is no single answer to this question; however, our basic knowledge of student housing preferences is also very limited. Although a number of studies have examined student housing (Holahan and Wilcox, 1978; Han, 2004; Charbonneau et al. ,2006; Stern et al,

196

2007; Brandon et al, 2008; Hassanain, 2008; Cross et al. ,2009; Araujo & Murray, 2010) there is a lack of research on students’ housing preferences, and methods and research instruments in this area remain underdeveloped. The current study is an attempt to partially fill this gap by developing and validating an instrument called the SAPI (Student Accommodation Preference Instrument), which can be used by university organizers and researchers. The SAPI was primarily developed by Khozaei et al. (2011), and its reliability and validity have been assessed. This instrument was conceptualized on the basis of similarities between residence halls and homes and was developed using exploratory factor analysis (EFA). Although the instrument had good reliability and validity and covered a large number of factors that influence student housing preferences, its questionnaire was extremely long. The purpose of this paper is to develop a valid and reliable shorter version of the instrument.

2. Review of studies on housing preferences A vast body of previous research was studied critically during the development of the student accommodation preferences index (SAPI).

In very early stages of this study, it was found that

there are very few direct references to reports on student housing preferences. Therefore, it is not enough to review the studies that have analyzed the aforementioned issues. Accordingly, other scholarly works addressing housing preferences and related subjects (e.g., satisfaction and expectations), as well as studies of student housing in general, were also examined as a source of inspiration. In the limited pages of this paper, the most direct studies on housing preferences are discussed, and a large numbers of other studies are omitted.

Borrowing from studies on housing preferences and choice, several influencing factors are examined in the study of residence preferences. These factors are examined at both the macro and micro level. Some other studies have canonized the influence of the demographic background of respondents on their preferences. At the macro level, factors include time, space, money and social relationships (Ge and Hokao, 2006), size of place of residence (Jong, 1977; Heaton et al., 1979; Hwang and Albrecht, 1987; Hempel and Tucker, 1979; Tremblay et al., 1980), functional congruity (Sirgy et al., 2005) and neighborhood attributes (Wang and Li , 2006; Lindberg et al. *Corresponding author (F Khozaei).

2012. American Transactions on Engineering & Applied Sciences. Volume 1 No.3. ISSN 2229-1652 eISSN 2229-1660 Online Available at http://TuEngr.com/ATEAS/V01/195-211.pdf

,1989). Other factors in residence housing preferences include outdoor environmental quality (Jim and Chen, 2007), location (Devlin, 1994, Thamaraiselvi & Rajalakshmi, 2008; Karsten, 2007; Lindberg et al., 1989), neighborhood attributes (Hempel &Tucker, 1979), local landscape (Nasar, 1983), safety, and proximity to the city, public transportation, proximity to workplace, sense of safety, medical and health facilities, and educational facilities (Wu, 2010).

At the micro level, the exterior facade of the residence (Nasar and Kang, 1999; Akalin et al., 2009; Stamps & Miller, 1993; Stamps, 1999), dwelling type (Opoku & Abdul-Muhmin 2010; O’Connell et al., 2006; Elliott et al. , 1990), convenience, security, price, orientation and layout (Wang and Li, 2006), as well as the dwelling’s architectural style (Devlin, 1994 a,b; Hempel & Tucker, 1979), are also examined in the study of housing preferences. Studies have also examined the role of safety, resale value, maintenance, amenities (Thamaraiselvi & Rajalakshmi, 2008), lot size, housing price, location, distance attributes (e.g., distance to shops, schools, facilities), range of housing styles available, and the size of the home (Reed & Mills, 2007).

Regarding the demographic background of respondents, studies have shown that housing preferences are linked to residents’ gender (Devlin, 1994b), family income, age, education, type of employment (Wang and Li, 2006), kinship, religion and attitude toward women (Jabareen, 2005).

In the vast body of literature on housing, few studies have focused on student housing preferences. For example, Roche et al. (2010) examined the housing preferences of 325 undergraduate students. They found that the students desired housing options that fulfilled their high expectations for privacy and amenities. These authors found that the majority of students preferred to live in apartment-style housing, and only 3.2% of students preferred to live in traditional residence halls. Roche et al. listed the top ten amenities for students: “private bedroom, onsite parking, double beds, onsite laundry facilities, internet access, proximity to campus, fitness center, private bathroom, cable TV and satellite dining” (50).

Students’ desire to personalize college residence hall rooms was examined in a study by Hansen and Altman (1976). They found that the majority of students decorated their living spaces soon after arriving on campus. Based on how the students had decorated the walls of their rooms,

198

the researchers teased out evidence pertaining to students’ values, personal interests and personal relationships. This study suggests the importance of providing students with the flexibility to personalize their living space. Oppewal et al (2005) found that factors such as a mixed- or single-gender floor, mixed- or single-course floor, shared toilet and shower, view from the room, distance from campus, age of the building, and weekly rent were influential factors in students’ housing preferences (Oppewal et al., 2005).

These studies provide relevant resources and concepts for the current study. However, the main concept in the development of the SAPI was that, in general, students prefer to live in home-like residence halls rather than institutional residence halls. Thus, the SAPI “is conceptualized on the basis of similarities between residence halls and homes” (Khozaei et al.

2011, 301). This concept has previously been discussed in the literature (e.g. Robinson, 2004; Thomsen, 2007; Khozaei et al., 2010). Accordingly, in developing the SAPI, contributing factors drawn from the literature review on housing preferences were combined and categorized into those factors that make residence halls similar to houses. This subject will be discussed further in the methodology section.

3. Methodology The main aim of this study is to achieve a shorter and more user-friendly version of the student accommodation preference index (SAPI) developed by Khozaei et al. (2011). Before discussing the procedure for shortening and validating the instrument questionnaire, we explain the steps in the development of the original index.

The key concept in the development of the instrument was the assumption that the current students prefer to live in home-like residence halls rather than in residence halls with more institutional characteristics. Residence halls and private homes were conceptualized as being similar in terms of 8 main factors: visual, facilities, amenities, location, personalization and flexibility of room, social contact, security and privacy (Khozaei et al. 2011, 305). With these 8 dimensions in mind, the related literature was studied critically to identify a pool of items (Pett et al., 2003). *Corresponding author (F Khozaei).

Figure 1: The development process of the SAPI (Student Accommodation Preferences Instrument (adapted from Khozaei et al. 2011.)

As can be seen in Figure 1, the development of the SAPI involved several steps. The development began with a critical review of previous studies on housing, and the similarities of residence halls and student housing preferences were critically examined. The factors derived from the literature were listed in the pool of items. The items were then categorized into 8 constructs, visual, facilities, amenities, location, personalization and flexibility of the room, social contact, security and privacy (khozaei et al. 2011, 299), which were assumed to represent the similarities between residence halls and private homes. Once the primary draft was complete, it was sent to several experts at Universiti Sains Malaysia (USM) and other universities, six undergraduate and

200

Fatemeh Khozaei, T Ramayah, and Ahmad Sanusi Hassan

graduate residence hall students and two statisticians from USM. Based on the experts’ suggestions, 5 questions were deleted, and the first version of the instrument, with 69 items, was produced.

In the next step, to examine whether the questions can be understood by students and whether there are questions that lower the reliability of the instrument, a pilot test was conducted. This pilot test was conducted with approximately 10 percent (70 students) of the sample population (Pett et al 2003) who were living in any of the residence halls of USM. The questionnaire was designed on a four-point Likert scale that was constructed as follows: (1) not at all; (2) very little; (3) mostly; and (4) very much. Data were analyzed using PASW Statistics 17, and the internal consistency of the index was determined through the application of Cronbach's alpha, yielding a reliability coefficient from 0.70 to 0.91. Based on the internal consistency of the items, none of the items was deleted in this stage. After conducting the pilot test, the major study was conducted with 752 residence hall students (for more information about the demographics of respondents, please see Khozaei et al. 2011).

4. Exploratory factor analysis To assess the construct validity of the instrument, an exploratory factor analysis was conducted using the principal component analysis with varimax rotation. The analysis extracted 6 factors that had eigenvalues greater than 1. The total variance explained was 46.55% of the total variance. Therefore, at this stage, the instrument was reduced from 8 dimensions to 6 dimensions: facilities and amenities, visual, convenience of student’s room, location, social contact and security (khozaei et al. 2011, 300). In addition, the reliability of each factor was assessed and yielded a high reliability coefficient, from 0.73 to 0.92. Through this process, the validity and reliability of the instrument were tested. The developed instrument was 64 items long with 6 preference factors: facilities and amenities (22 items), visual (14 items), convenience of room (10 items), location (7 items), social contact (6 items) and security (5 items). Because the questionnaire was very lengthy, we attempted to develop a valid and reliable shorter version of the instrument. *Corresponding author (F Khozaei).

5. Confirmatory factor analysis To conduct the confirmatory factor analysis, another set of data was collected from students living in university residence halls.

In total, 204 respondents replied and returned the

questionnaires. The demographic makeup of the respondents is presented in Table 1. Two main criteria, validity and reliability, were used to test the measures. Reliability is a test of how consistently an instrument measures a specific concept, and validity is a test of how well an instrument measures the particular concept it is intended to measure (Sekaran & Bougie, 2010).

SmartPLS software (http://smartpls.com) (Ringle et al., 2005) was used to assess the validity and reliability of the instrument.

Two important construct validities, convergent validity and

discriminant validity, were assessed based on the recommendation of Chin (1998). Convergent and discriminant validities can be inferred if the PLS indicators fulfill the following criteria (Lee & Chen, 2010):

Convergent validity assesses whether a measure is correlated with other measures, whereas discriminant validity assesses whether the measurement for one variable is correlated or not correlated with the measurement for other variables (Lee & Chen, 2010).

(Hair et al. 2010), with the lowest loading at 0.598 and the highest loading at 0.927. Composite reliability values , which represent the degree to which the construct indicators indicate the latent construct, ranged from 0.839 to 0.905, exceeding the recommended value of 0.7 (Hair et al., 2010).

The average variance extracted (AVE) measures the variance captured by the indicators relative to measurement error. It should be greater than 0.50 to justify using a construct. The average variance extracted was in the range of 0.502 to 0.706.

Through the above process of confirmatory factor analysis, we reduced the instrument from 60 items to only 28 items, ensuring that there were at least 4 items to measure each construct so that they were over-identified. The 28 items included 6 factors: facilities and amenities (5 items), visual (7 items), convenience of room (5 items), location (4 items), social contact (3 items) and security (4 items). Next, we proceeded to test the discriminant validity. The discriminant validity of the measures (the degree to which items differentiate among constructs or measure distinct concepts) was assessed by examining the correlations between the measures of potentially overlapping constructs. Items should load more strongly on their own constructs in the model, and the average variance shared between each construct and its measures should be greater than the variance shared between the construct and other constructs (Compeau, Higgins & Huff, 1999).

As shown in Table 4, the correlations for each construct were less than the square root of the average variance extracted by the indicators measuring that construct, indicating adequate discriminant validity. In total, the measurement model demonstrated adequate convergent validity and discriminant validity.

6. Discussion Previous studies support a link between housing preferences and the demographic background of residents (Devlin, 1994, Wang & Li 2006). Thus, in studying student housing preferences, demographic background can be a contributing factor. Students in the temporary residences of residence halls are often seen as homogenous groups with similar needs and requirements.

However, the reality is that students’ needs and requirements are not exactly the same, and students from different backgrounds might have different needs and requirements. However, it is also true that a typical residence hall rarely satisfies all types of students. Thus, the attributes of an adequate residence hall for students must be found in the students’ own responses.

Despite the great importance of understanding of students’ preferences for residence halls, this area of study has been overlooked. This study attempts to partially fill this gap by developing a user-friendly instrument to examine students’ housing preferences. This study is grounded in a previous study by Khozaei et al. (2011) that developed and validated the student accommodation preferences index (SAPI) with 6 dimensions and 64 items. This instrument was developed as a tool for the study of university students’ preferences for on-campus residence halls. The conceptual framework of this instrument was based on the similarity between residence halls and private homes. The original version of the SAPI covered a large number of residence hall attributes and provided the researchers with detailed information. Specifically, the facilities and amenities section of the instrument included a wide range of items. The present study aimed to trim the number of items within the same number of dimensions to produce a shorter version of the instrument that remained valid and reliable. Data were collected from 204 respondents using the original version of the SAPI. Confirmatory factor analysis and other analyses were conducted on the data. The result was a validated and reliable version of the SAPI with only 28 items in 6 factors (Figure 2) : facilities and amenities (5 items), visual (7 items), convenience of the room (5 items), location (4 items), social contact (3 items) and security (4 items). Facilities and amenities included 24hour study rooms, indoor pools (especially for women), fitness rooms, ATMs and storage rooms. The dimension of visual preferences included a beautiful exterior and facade, a new or newly renovated building, proper natural and artificial lighting in students’ rooms, attractive interior in students’ rooms, new or good-condition furniture in students’ rooms, modern and stylish

furniture in students’ rooms, and beautiful and stylish furniture in the TV room and other social spaces. The dimension of room convenience consisted of 5 items: mini refrigerator in the room, air conditioner in room, the ability to move furniture and redecorate the room, the potential to divide the room into studying, eating and sleeping spaces, and underbed space that could be used as storage. The location dimension included the following items: proximity to the bus stop, academic facilities, university sports facilities, and the university clinic. The social contact dimension consisted of 3 items: a double shared room, a large area for students to gather, and a sitting room for every few rooms. Finally, the security dimension included the following: requires card access to enter the residence hall, requires card access to enter the room, room doors equipped with viewing devices, and 24-hour security.

7. Conclusion The student accommodation preferences index (SAPI) can provide a basis for further studies on student housing preferences. This instrument will allow researchers to examine and compare students’ preferences in different contexts. This study suggests that further studies be conducted on the role of demographic background on students’ preferences. Further studies might also examine the most-preferred items of each dimension and compare them among students.

ABSTRACT

Article history: Received 11 April 2012 Received in revised form 25 June 2012 Accepted 16 July 2012 Available online 20 July 2012

Natural surveillance by adjoining building occupants and public space users is one of the major strategies of crime prevention in public places. Lighting, vision through building openings and land uses around facilitate the surveillance by building occupants and public space users. This study inquires about the influence of mix of land uses and lighting of the area and the number of visible openings of adjoining buildings on the perceived personal security of people waiting at the bus stops during night hours. The detailed land use inventory, number of visible building openings and subjective assessment of lighting were recorded for the selected bus stops. The people waiting at the bus stops were interviewed to assess their perception of security. The results revealed that the perceived security is highest in bus stops from where more number of adjoining buildings openings are visible and located in areas with diverse mix of uses and good lighting. The land use mix of the area has a greater influence than lighting and visible openings on perceived security.

This study demonstrates that the aspects of built environment contribute to perceived security and these aspects are to be considered in the location of bus stops.

1. Introduction Natural surveillance is one of the common principles recommended by various place based crime prevention theories such as defensible space, situational crime prevention and crime prevention through environmental design (CPTED) to alleviate incidence and fear of crime.

Personal safety and security issues are prime concerns for people while waiting at the bus stops.

Natural surveillance provided by adjoining building occupants and people on the streets enhances the perception of personal security of people waiting at the bus stops. Features of the physical environment play a major role in providing natural surveillance. Surveillance by adjoining building occupants depends on the number openings through which the people have direct view of the bus stop and also on the use of the interior spaces. The level of surveillance by people on the streets depends on the continuous presence of people which in turn depends on the level of mix of land uses of the area. At night time the surveillance is facilitated by provision of lighting so that the building occupants and people on the streets have clear visibility of bus stops. The previous studies have focused mainly on individual contribution of mix of land uses, lighting and unobstructed openings of surrounding buildings to surveillance and thus to perception of personal security, whereas the collective influence of these features were not dealt with. Hence this study is focused on (a) assessing the level of natural surveillance at bus stops offered by the mix of land uses, lighting and visible openings of surrounding buildings of the respective bus stop environments; (b) association between the level of natural surveillance and the rated perceived personal security at bus stops; and more importantly, (c) the influence of these features of bus stop environments on the perceived personal security of people waiting at the bus stops during night time.

2. Review of Literature 2.1 Natural Surveillance Natural surveillance offered by features of the physical environment plays a significant role in alleviating the incidence of crime and enhancing the perceptions of personal security in public places. Jane Jacobs (1961), in ‘The Death and Life of Great American cities’ suggested that the eyes of those natural proprietors of the street must be scanning it all the time for a city street to be

successful. Oscar Newman’s (1973) defensible space focused on natural surveillance in addition to territoriality, images and milieu. The basic principles of crime prevention through environmental design (CPTED) include natural surveillance together with image/ maintenance, natural access control and territorial reinforcement (Crowe, 2000). Natural surveillance consists of increased visibility of urban places directed at keeping intruders under observation and undesirable behaviour under control (Sorensen et al., 2008). Natural surveillance of urban places is provided by occupants of the buildings around and the public on streets (Desyllas et al., 2003). People feel more secure in areas with high surveillance due to the confidence that there are more chances for people to intervene or report crime if any. The offenders also look for desolated places since better surveillance make them feel more vulnerable as they may be identified or caught while committing a crime.

2.2 Natural Surveillance at Bus Stop Environments Bus stops, being one of the important urban places, are expected to provide a safe and secure waiting environment for the people in addition to other needs such as visibility, easy access to the bus, and comfort and convenience of people. The concerns for personal security affect the travellers’ decisions of what stops to use and their confidence in using those stops (Tucker, 2003).

In bus stop settings also, natural surveillance provided by occupants of the building around and the public on the streets enhances the perceptions of personal security of people waiting at the bus stops along with other environmental design strategies. Research on bus stops revealed that low-crime bus stops offered better surveillance opportunities from surrounding establishments (Loukaitou-Sideris, 1999); and general lack of people and activity contribute to anxiety and fear that no one will be there to help if a crime occurs in transportation settings (Loukaitou- Sideris and Camille Fink, 2008).

2.3 Natural Surveillance and Physical Environment Natural surveillance refers to the arrangement of physical design features involved with the activities and the people in order to maximise the opportunities for surveillance (Cozens, 2002).

Desyllas, et al., (2003) mentioned that the occupants of surrounding buildings provide surveillance by seeing public space from windows and building entrances. It may be assumed that the *Corresponding author (Subbaiyan G). Tel: +91-9842481311. E-mail address: 2012. American Transactions on Engineering & Applied Sciences. subbaiah@nitt.edu.

surveillance from surrounding buildings depends on the number of unobstructed openings visible from the bus stops, in addition to the presence of people in the surrounding buildings. The buildings that are occupied by uses or activities that are functioning till late night hours ensure continuous presence of people in the buildings and thus provide a continuous surveillance. Vogel and Pettinari (2002) argued that the street level commercial activity and upper level residential activity provide round the clock activity and eyes on the street, where as public buildings such as post office, fire station etc., fall short of providing activity and eyes on the street after working hours.

To provide natural surveillance of urban places, there need to be continuous presence of people on streets. Jacobs (1961) advocated diverse land use streets so that there is a continuous flow of people enhancing natural surveillance on city streets. Angel (1968) asserted that with higher levels of activity, crime falls because there are enough people to assure informal surveillance of the site (Robinson, 1999). Diverse mix of land uses ensures some or other activities being carried out for most part of the day, which in turn increase the continuous presence of people on streets all the time. Areas with poor mix of land use or single use areas become deserted during certain hours of the day creating a suitable environment for the criminal activities.

Thus the mix of land uses in surrounding buildings of bus stops contributes to both surveillance provided by the occupants of surrounding buildings and people on streets.

Atkins et al., (1991) noted that lighting will encourage noticing suspicious activities and increasing opportunities for surveillance. During night hours good lighting improves the visibility and also reduces the fear of general darkness which, in turn, encourages increased street usage by the people. Both enhanced visibility and increased street usage may enhance possibilities for natural surveillance (Welsh and Farrington, 2009). It is understood that the features of the physical environment - mix of land uses, unobstructed openings and lighting independently influence the level of natural surveillance offered by that environment and thus impact the perceptions of personal security of people waiting at the bus stops. However the collective influence of these features of the physical environment on the level of natural surveillance and perceptions of personal security of people need to be investigated.

3. Method 3.1 Selection of Bus Stops The bus stops in Tiruchirappalli, the fourth largest city in Tamil Nadu state India with an approximate population of 1 million in the year 2010, were selected for the present study. Based on the study of night time photographs of all bus stops within Tiruchirappalli city corporation limits, *Corresponding author (Subbaiyan G). Tel: +91-9842481311. E-mail address: 2012.

14 bus stops were selected. Bus stops with varying levels of mix of land uses, area lighting levels and visible openings of the surrounding buildings were considered for the selection. The selected bus stops are labelled from A to N in Figure 1.

3.2 Features of Physical Environment In this study three physical environmental measures i.e. mix of use, street lighting and visible openings of the surrounding buildings were considered for determining the level of surveillance in the bus stops. Features of physical environment of bus stops were rated by five trained under-graduate students of Architecture by visiting the bus stops between 6pm and 9pm.

3.2.1 Mix of Land Uses A detailed inventory of uses, within an area measuring approximately 45m radius around the bus stops were undertaken, by counting the number of establishments in a particular land use classification and in the case of commercial activities the type of business and the size (small, medium, and large) of the establishments were also recorded. Three Architect- Planners independently rated the bus stops taking into consideration the mix of different land uses, scale and types of commercial activities in the surrounding area, and the number of people present in the vicinity of bus stops environments. Thus the bus stops were categorized in to three groups, namely bus stops with good, medium and poor mix of land uses as stated below: Bus stops with good land use mix: B, F, G and H Bus stops with medium land use mix: A, C, D, E, I, J, K and N Bus stops with poor land use mix: L and M. 3.2.2 Lighting A subjective assessment of lighting at bus stops and their immediate environment was carried out by recording the uniformity of lighting (absence of dark spots) on a five point scale ranging from very good (5) to very poor (1). Based on the analysis of uniformity of lighting, the bus stops were classified into two groups as stated below: Bus stops with good lighting: A, B, E, F, G, H, I and N Bus stops with poor lighting: C, D, J, K, L and M

3.2.3 Openings of Surrounding Buildings Building wise number of open, glazed (fully transparent) and lit openings of surrounding buildings within 15m radius that were clearly visible from the bus stops (not obstructed by physical features) were independently counted by the students. Types of openings include open or transparent shop fronts, doors and windows of other establishments. The bus stops were dichotomised into two groups about the mean value of number of visible openings of buildings.

The bus stops were grouped as stated below: Bus stops with more openings: B, E, F, G, H, I and N Bus stops with less openings: A, C, D, J, K, L and M.

3.3 Features of Physical Environment Based on levels of mix of land use, lighting and number of visible openings of surrounding buildings, the bus stops were categorised in to five groups (refer Table 1). Following assumptions were made on level of surveillance at bus stops: very good in bus stops B, F, G and H; good in bus stops E, I and N; medium in bus stop A; poor in bus stops C, D, J and K; and very poor in bus stops L and M. Based on the level of surveillance it was expected that the people would rate B, F, G and H as very safe; E, I and N as safe; A as neutral; C, D, J and K as unsafe and L and M as very unsafe bus stops.

3.4 Participants and measure of Perceived Personal Security The perceived personal security was measured by asking the people waiting at the selected bus stops to report their concerns about personal security against crime and nuisance behaviour during night hours. The respondents were asked to rate their concerns about personal security on 5-point *Corresponding author (Subbaiyan G). Tel: +91-9842481311. E-mail address: 2012.

scale ranging from very high (1) to not at all (5). The respondents were also asked about their opinion about the contribution of land use mix around bus stops, area lighting and the visible openings of the surrounding buildings for the personal security of people waiting at the bus stops on a 3- point scale ranging from contribute to safety (3) to problem for safety (1). The survey was carried out after dark between 6 p.m. and 9.30 p.m. The total sample consisted of 453 people and the number of people surveyed in each bus stop varied from 26 to 42. The sample consisted of 205 male and 248 female; and 34 people above 50 years of age, 213 people in the range of 31-50 years of age, and 206 people below 30 years of age.

4. Findings and Discussion 4.1 Grouping of Bus Stops based on Perceived Security The mean perceived personal security levels at the bus stops are given in Table 2. Simple Analysis of Variance (ANOVA) revealed significant differences [F (13,439) =6.098, p<.001] in the reported perceived security levels of people among the bus stops. Based on the post-hoc analysis of bus stops level perceived security of people, the bus stops were categorised into five groups as described below: B and F as very safe; G and H as safe; C, E, I and N as neutral; A, D, J and L as unsafe; and K and M as very unsafe bus stops.

4.2 Comparison of Surveillance and Perceived Security of People at Bus Stops The individual bus stops with their rated safety level and the mean perceived security levels of bus stops groups based on the level of surveillance are given in Table 3. Simple Analysis of Variance (ANOVA) carried out revealed that there was a significant difference [F (4,448) =16.475, p<.001] in the perceived security level of people between the bus stops groups. Post-hoc analysis

revealed that the mean perceived security level of people in bus stops group with very good surveillance was significantly higher than that of other groups, whereas the mean perceived security level of people in bus stops group with very poor surveillance was significantly lower than that of bus stops groups with very good and good surveillance.

On comparison of level of perceived security of people at individual bus stops with the respective level of surveillance the following were noticed: a)

Out of the four bus stops with very good surveillance (good mix of uses, good lighting and more openings), bus stops B and F were rated as very safe; and G and H were rated as safe bus stops.

b)

Bus stops E, I and N with good surveillance (medium mix of uses, good lighting and more openings) were rated as neutral bus stops.

c)

Bus stop A with medium surveillance (medium mix of uses, good lighting and less openings) was rated as unsafe bus stop.

d)

Out of the four bus stops with poor surveillance (medium mix of uses, poor lighting and less openings), bus stop C was rated as neutral, bus stops D and J were rated as unsafe and K was rated as very unsafe bus stops.

e)

Bus stops L and M with very poor surveillance (poor mix of uses, poor lighting and less openings) were rated as unsafe and very unsafe bus stops respectively.

These findings largely confirm the assumptions except in the case bus stop A with medium surveillance was rated as unsafe whereas the bus stop C with poor surveillance was rated as neutral bus stop. It was also noticed that the mean perceived security of people did not vary significantly among bus stops groups with very medium, poor and very poor surveillance. On comparison of individual features and perceived personal security level at bus stops, the following were observed: a) Bus stops located in areas with good mix of uses were rated as very safe and safe bus stops, the bus stops located in areas with medium mix of uses were rated as neutral, unsafe and very unsafe bus stops and bus tops located in poor mix of uses were rated as unsafe and very unsafe bus stops. b) Bus stops with good area lighting were rated as very safe, safe, neutral and unsafe bus stops; and bus stops with poor area lighting were rated as neutral, unsafe and very unsafe bus stops. c) Bus stops with more number of visible openings of surrounding buildings were rated as very safe, safe and neutral bus stops; and bus stops with less number of visible openings of surrounding buildings were rated as neutral, unsafe and very unsafe bus stops.

From these observations it may be assumed all the three features of bus stop environments had more or less similar affect on the perceived security of people at bus stops.

4.3 Peoples’ Opinion about the Contribution of Features of Physical Environment for the Personal Security The respondents’ opinion about the contribution of features of physical environment for the personal security was analysed at the bus stops group level of each of the features independently. In case of land use the chi-square test revealed a significant association [χ2 (4) = 41.683, p< .001] between the level of mix of land uses and the peoples’ perception about the contribution of surrounding land uses to the personal security. The percentage of people expressed that the surrounding uses contribute to the personal security was 69.5% in bus stops group with good mix of uses; 40.5% in the group with average mix of uses; and 32.5% in the group with poor mix of uses. In case of lighting the chi-square test revealed a significant association [χ2 (2) = 93.115, p< .001] between the quality of lighting and the peoples’ perception about the contribution of lighting to the personal security. The percentage of people expressed that lighting contribute to personal security was 27.2% in bus stops group with good lighting and only 1.5% in the bus stops group

with poor lighting. In both bus stops groups majority of people expressed neutral about the contribution of lighting to personal security. In case of openings the chi-square test revealed a significant association [χ2 (2) = 49.650, p< .001] between the number of visible openings and the peoples’ perception about the contribution of openings to the personal security. In bus stops group with more number of visible openings 31.8% of the people expressed that the openings contribute to personal security; and in the group with less number of openings 47.5% of the people expressed that the lack of openings were problem for personal security. Therefore it may be concluded that there was clear association between the level of physical features and peoples’ opinion about the contribution of these elements to their personal security while waiting at the bus stops.

To establish the relative importance of these physical features in predicting the perceived security of people at bus stops multiple regression analysis was conducted taking the respondents’ opinion about contribution of land use, lighting and visible openings of buildings to personal security as independent variables. Land use yielded the highest beta weight of all the independent variables (0.370), followed by lighting, (0.211) and openings (0.147). The adjusted R2 was 0.288, suggesting that twenty nine percent of the variance in perceived personal security was explained by the independent variables in this model (refer Table 4). The R2 value 0.288 shows low linear relationships between the independent variables and the dependent variable. However, the model is statistically significant at the .001 level and such low R2 value was noticed in similar studies.

the perceptions of personal security of people waiting at the bus stops during night time. Though the findings largely confirm the assumptions, the minor variation in the association between the levels of natural surveillance and perceived personal security could be mainly because the perception of personal security is not solely dependent on surveillance and also on the interactive effect of various other environment cues. The perceptions of personal security also seem to have significant relationship with each of the features of the environment. The peoplesâ&#x20AC;&#x2122; opinion about the contribution of these individual features to the personal security of people waiting at the bus stops was significantly related to the level of the individual features. Though all three features seem to clearly predict the perceived security during night time, land use mix seems to be the most influential, followed by lighting and visible openings of surrounding buildings. Each environmental feature contributes to more than one environmental design strategies that influence the perceptions of personal security. For example lighting contributes to natural surveillance and also helps to reduce concealment spots. Larger study on this subject is required as the perceptions of personal security are influenced simultaneously by various aspects of environmental design.

Hence this study can be expanded to investigate the impact of land use mix and various other environmental features on peoplesâ&#x20AC;&#x2122; perceptions of personal security in bus stop settings with an objective to formulate guidelines for location and design of bus stops.

The architectural literatures propose various factors in determining the continuity of architectural identity. In terms of visual appearance, these factors are grouped in five different areas namely: Mass and Articulation, Openings, Architectural Detail, Materials and Principles of façade arrangements. In spite of the diversity of the subject in the field of research, the mutual influence of factors on one another still uncovered. Approach: This study aims to examine the significant correlation between factors affecting the continuity of architectural identity in Erbil City. A proper questionnaire has been adapted to be used as measuring scale. Results: The Pearson product-moment coefficient correlation results show that all factors are correlated positively with continuity of architectural identity with the exception of (principles of façade arrangements) factor. Conclusion: Based on the hypotheses testing, this study reveals a positive association between house façade modernization factors and the continuity of architectural identity. The results conclusively prove that (mass and articulation, openings, architectural detail, materials) factors have a crucial impact on the continuity of architectural identity.

Keywords: Architectural Identity; House facade modernity; Visual appearance; Correlation.

1. Introduction Façades are the public face of architecture. It is the exterior face of a building that provides comfortable enclosure (Knaack et al., 2007). It's the most significant part of building’s exterior image that shape its cultural identity (Schulz 1971, Rapoport 1969). In other words, Facades are the physical evidences for aesthetic evolution of the city as well as the effective aspects of architectural transformation (Elshahed, 2007). Generally, house facade contains three main zones: a base that connects the building with the ground; a middle zone with its openings; and the roof zone which connects the building to the sky by silhouette (Moughtin et al., 1999). *Corresponding author (Salahaddin Yasin Baper) Tel/Fax: +964-7504534859.

Based on the findings of Gromlich (1989), house facade incorporates various features that produced from the arrangement of roof, openings, materials, and finishes. This study revealed that main factors affecting the façade design are related to the composition, shape, texture, and color of its components. Consequently, the analysis of house facade formal structure provides relevant information to understand its identity as the socio-cultural performance of façades is the indicator of its architectural value (Pellitteri, 1997).

2. Factors affecting the visual aspects of house façade Scholars in this field of visual analysis studies factors affecting the design of house facade in different ways due to the variation of appearance and arrangement of façade elements in urban environments. This section will review the relevant literature to identify fundamental house facade factors in term of architectural identity visual aspects. Generally, house is a cultural phenomenon; its form is influenced by the climatic forces, site features, materials and construction techniques therefore, the formation of the house is affected by the socio-cultural and socio-economic structure of a society which contains many cultural traces of the past (Rapoport, 1969). The effect of culture on the formation of house design appears to be an important factor is shaping its façade (Sari et al., 2011).

From different point of view, the powerful factor influencing building facades is the sensory value of ornaments as architectural details (Salingaros, 2003; Akalin et al., 2009). Scholars concluded that ornament and decoration subdivide building façades on many different scales and influenced directly the visual appearance of facades (Stamps III, 1999; Salingaros, 2003; Akalin et al., 2009). For Moughtin et al., (1999) the contrast of elements and the number of elements within the building facade are the fundamental factors in measuring the visual richness of building facades. In this regards, (Rapoport 1990) pointed out that the measurable tool for visual complexity depends upon the perceived number of elements within the facade, and the degree of change for its components. The study concludes that Visual complexity relates to the rate of change of the noticeable differences.

Others clarify that the influence of building elements orderliness within house facades is an effective factor in determining the complexity of architectural form (Nasar, 1983; Meiss, 1990; Niezabitowski, 2009).

They pointed out that the repetition, similarity; common enclosure,

symmetry, and orientation of the building elements play a part in formulating building facades.

From different point of view, the characteristic proportions of the windows, their positions in the wall, and their relationships with the solid areas tend to give a sense of coherence in architecture (Figure 1) therefore, common scales, materials, textures, and openings are considered to be the effective parameters in shaping the architectural facades (Whang, 1998). In parallel, Askari & Dola (2009) explains that architectural style, shape, decoration, and material were respectively the most important visual elements in presenting building facades while the effect of Color and texture were less important.

3. Methodology In this paper, Quantitative method is carried out to examine the significant correlation between factors affecting the continuity of architectural identity in Erbil city. This method attempts to measure the degree of continuity in house facade physical elements. Therefore, the measurements will provide the essential connection between practical observation and statistical expression of quantitative relationships. For the purpose of the study, a structured questionnaire survey is conducted to generate statistics and separate variable to be counted and modeled statistically.

Hence, Self-administered questionnaire with multiple choices of questions is organized.

This study chose the probability sampling design using a simple random sampling process as it seeks representativeness of the wider population, have less risk of bias and offers the generalizations (Cohen et al., 2000; Sekaran, 2003). The population for this survey is distributed into two groups: The first group includes upper level studio students (3rd, 4th, 5th year and post graduate) students in Architectural Department /Salahaddin University while the second group includes architects who registered in Kurdistan Engineers Union (KEU) and currently working inside Erbil city. Accordingly, a total of 273 completed questionnaires collected.

4. Data analyses For the purpose of quantitative data analysis the SPSS (Statistical Package for the Social Sciences) software was used to provide statistical analysis of data and give details for in-depth data access and preparation, analytical reporting, graphics and modeling. The quantitative data was analyzed in two directions as follow: Correlation analysis was used to explore the relationships among the variables (Every independent variable will be correlated to a dependent variable). The role of correlation is to capture the similarity or difference between the variables. It measures the degree of association between the values of related variables given in the data set. Then, the mutual influence of variables on one another will be traced.

Regression analysis: The general purpose of multiple regressions is to make a prediction about the dependent variable based on its covariance with all the concerned independent variables. *Corresponding author (Salahaddin Yasin Baper) Tel/Fax: +964-7504534859.

Accordingly, an equation will represent the best prediction of the continuity of architectural Identity from several independent variables.

5. Results The objective of this study is to examine the relationships of house façade modernity factors (Mass & Articulation, Opening, Architectural Details, Architectural Material and House façade Arrangement Principles) and continuity of architectural identity in Erbil city. The aim is to determine the significant correlation between the factors that affect the continuity of architectural identity and to test hypothesis. Thus, correlation analysis (Pearson Product Moment Correlation Coefficient Test) was used to explore the relationships among the variables as well as to describe the strength and direction of the liner relationship between variables. Every independent variable is correlated to a dependent variable. In this regards, Kumar et al. (2005) explains that the degrees of correlation can be positive or negative. Correlation coefficients can range from -1.00 to +1.00. The value of -1.00 represents a perfect negative correlation while a value of +1.00 represents a perfect positive correlation. A value of 0.00 represents a lack of correlation.

The two–tailed test of statistical significant from 0.01-0.05 was the main procedure of the correlation analysis. Table 1 and Table 2 present the outcomes of correlation analyses. In general, the house façade modernity has a significant positive correlation with the continuity of architectural identity. The correlation coefficient range 0.504 at p < 0.01.

5.1 The Relationship between House Façade Mass & Articulation and the Continuity of Architectural Identity: The result of correlation analysis for the relationship between Mass & Articulation and the continuity of architectural identity (Table 1) show that the correlation coefficient is r = 0.307 at p < 0.01. This result is an indication of a significant positive relationship between Mass & Articulation and the continuity of Architectural Identity. It can be deduced that Mass & Articulation play a part in determining the continuity of architectural identity.

5.2 The Relationship between House Façade Openings and the Continuity of Architectural Identity The Pearson product–moment linear correlation was used to determine the existence of the above relationships, the correlation coefficient was r = 0.252 at p < 0.01. As a consequence, there is significant positive relationship between House Façade Openings and the continuity of Architectural Identity. Therefore, the design of openings in house facades has a direct impact on the continuity of architectural identity.

5.3 The Relationship between House Façade Architectural Details and the Continuity of Architectural Identity As indicated in Table 3, the correlation coefficient was (r = 0.276 at p < 0.01). This means the availability of significant positive relationship between House Façade Openings and the continuity of Architectural Identity. Therefore, the house façade architectural details have an impact on the continuity of architectural identity.

5.4 The Relationship between House Façade Materials and the Continuity of Architectural Identity In order to determine the correlation between House Façade Materials and Continuity of Architectural Identity, the Pearson product–moment linear correlation was conducted. Table 3 presents the outcome of correlation coefficient for the above variables (r = 0.236 at p < 0.01). This result implies that house façade materials have direct influence on the continuity of architectural identity.

5.5 The Relationship between House Façade Arrangement Principles and the Continuity of Architectural Identity As demonstrated in Table 3, the correlation analysis for the relationship between house facade arrangement principles and the continuity of architectural Identity produced following facts (r = 0.095 at p = 0.119). This result refers directly to a very weak relation between mentioned variables. However, it was not statistically significant.

The lack of relation or very weak

relationship between house façade arrangement principles and the continuity of architectural identity is an indication that house façade arrangement principles have less influence than the other variables.

Based on correlation analyses in Table 3, the overall influence positively correlates to the most of independent variables, namely: Mass and Articulation, Openings, Architectural Detail and Materials with the continuity of architectural identity. With the exception of house façade arrangement principles that correlates in a very weak relation to the study’s main dependant variable. The Pearson product-moment coefficient correlation results reveal that the strongest association is related to the first parameter (Mass and Articulation) with (r) value of 0.307, followed by Architectural detail (r) = 0.276, then Openings (r) = 0.252, and finally House façade materials (r) = 0.236. These results conclusively prove that house façade modernity factors have a crucial impact on the continuity of architectural identity.

After identifying the overall influence and correlations between the variables, a multiple

232

Salahaddin Yasin Baper and Ahmad Sanusi Hassan

regression analysis was conducted to test the relationship further, make a prediction about the dependent variable based on its covariance with all the concerned independent variables and formulate an equation that represent the best prediction of the continuity of architectural Identity from several independent variables.

The collective effect of the independent variables formulates the mathematical formula of the study. Hence, the multiple regression analysis was employed to determine the variance of each component of house façade modernization factors. Five parameters were used as independent variables, and the continuity of architectural identity was set as the dependent variable. The recommended model was performed by determining the collective effect of the independent variables namely, (1) Mass and Articulation, (2) Openings, (3) Architectural details, (4) Materials and (5) House façade arrangement principles towards the overall perceived of the continuity of architectural identity. In the light of the above, a regression model was developed in settling the relationships between variables. The model is as follows.

Continuity = β + β1 Mass & Articulation + β2 Openings+ β3 Architectural Details + β4 Materials + β5 Arrangement Principles + ε Where, Continuity = the Continuity of Architectural Identity β

= constant

ε

= standard error

The model summary is showed in Table 4 and the summary of multiple regression analysis is presented in Table 5. Therefore, the R2 for this model is 0.254 (Adjusted R2= 0.251), indicating that the house façade modernity factors explained 25.4% of the variation towards the continuity of architectural Identity.

Dependent Variable: Identity In terms of importance, the “Mass & Articulation” parameter (β=0.192, p= 0.003) and the “Architectural details” parameter (β=0.108, p=0.020) have significant positive associations with continuity of architectural Identity. These results reveal that “Mass & Articulation” parameter is the most influential in interpreting the continuity of architectural Identity, because every unit of change in this parameter is associated with a 0.192 change in the continuity of architectural *Corresponding author (Salahaddin Yasin Baper) Tel/Fax: +964-7504534859.

Identity. Every unit of change in the “Architectural Details” parameter is related to a 0.108 in continuity of architectural Identity. Interestingly, although not significant, “Openings” (β =0.086, p=0.167), “Materials” (β=0.105, p=0.097), and House façade arrangement principles ( =0.080, p=0.715) have positive relationships with the continuity of architectural identity.

6. Conclusions This paper reveals the positive association between the house façade modernization factors and the continuity of architectural identity in Erbil city.

The Pearson product-moment

coefficient correlation results showed that the (Mass and Articulation, Openings, Architectural Detail and Materials) factors are positively correlated with the continuity of architectural identity.

With the exception of house façade (Arrangement Principles) factor that correlates in a very weak relation to the study’s main dependant variable.

The correlation results revealed that the

strongest associations in proper sequence were as follow: firstly Mass and Articulation factor, followed by Architectural detail factor, then Openings factor, and finally Material factor.

These

findings conclusively proved that the house façade modernity factors have a crucial impact on the continuity of architectural identity.

On the other hand, the multiple regressions results indicate that the proposed model is proven statistically. It represented the prediction of the continuity of architectural identity from house façade modernity factors. In terms of importance, the house façade modernity factors explained more than quarter of the variation towards the continuity of architectural Identity. The multiple regressions analysis results revealed that the “Mass & Articulation” factor and “Architectural details” factor are the most influential in interpreting the continuity of architectural Identity, because every unit of change in these factors is associated with significant positive changes in the

234

continuity of architectural Identity. Accordingly, these factors could significantly predict the continuity of architectural Identity.

What once called a “house of all seasons” has now been christened “climate-conscious”, “bioclimatic”, “energy-efficient”, or “sustainable” architecture. These terminologies are just not a welter but have definite meaning with respect to context at given point of time.

In the present work the sustainable practices are identified by documenting the tribal settlements and habitat of Central India to understand the concept of indigenous habitat and its integration with nature. The study comprises of typology of settlement pattern with reference to physiographic features, site selection with appropriateness to respond to local climate and spatial organization of settlement to suit the functional need. Habitat study concentrates upon structural stability, climatic responsiveness to achieve physical comfort with the given building materials and technology. The underlying principles of sustainability of the settlement and habitat are studied and are compiled so that they can be applied in the modern context of course after necessary modifications to suit the present need and in order to achieve sustainable design solutions.

1. Introduction The art, architecture and tradition of tribal settlements are great indigenous vernacular expression of the diverse culture of India. Tribal people have through their efforts, over thousands of years, created rich and colorful styles of vernacular architecture, responding to local environments. This reflects an evolved response to geography, climate, distribution of ethnic peoples and sustainable habitats. (Wang and Cai, 2006). The tribal population of India is scattered throughout the country and about eight percent of Indian population is tribal. The percentage of tribal population is high in the geographically remote areas, the islands in south, south-west and the mountain ranges of north and small & isolated states of north east.

The reason for more

percentage of tribal in the states can be attributed to the geographical locations like islands, rivers and mountain ranges. In Central India the state of Madhya Pradesh has the highest population of tribes, which, as per 2001 census constitutes the 20.26 % of the total population of the state.

The state of Madhya Pradesh which is the Central India is termed as heart of India due to its geographical conditions and it is also lung of India as its 40 percent area is under forest cover. The state straddles the Narmada River, which runs east and west between the Vindhya and Satpura mountain ranges; this ranges and the Narmada are the traditional boundary between the north and south of India. The tribes of Central India have the simplest of lifestyles with a rich culture still untouched by modernity and traditions as old as their origin.

The Central India was taken as the region for study and the tribes selected are Gond, Bhil, Korku and Bharia. The tribes were selected from varied geographical locations of Narmada River basin. The basin can be classified as upper and lower hilly areas which are dense forests, upper middle and lower plain with fertile soil suitable for cultivation. The present paper is an attempt to identify the sustainable practices of the tribal settlements as well as architecture of their houses on which the impact of local niche is obvious.

2. Location and Occupation The geographical aspect of the region has been a prominent decider on the distribution of tribal communities in the state. The Tribes are widely spread on both the banks of Narmada in the Vindhyan and Satpura mountain ranges in the dense forests, thus making them impervious to any

outside intrusions. This helped them maintain their culture and customs safe and continue till present day. They indulge in various activities to earn their livelihood. Earlier they were semi nomadic people but most of them have now settled down and have chosen their occupation. The tribes are an agro-silvicultural community and their forest dependency is high, in the hilly tracts, most of the tribes cultivate their land and in springs they migrate to Narmada river plains for harvesting where they are engaged as laborers. As they are a bailiwick of their topography, few tribes like bhils were employed as hunters in the pre-independent India. In that age of history, they were also recruited in the armies of kings and served as soldiers. The forests are home to them and provide sustenance in the form of forest produce, water, grazing grounds and habitat for shifting cultivation (Sarin, 2005).

3. Climatic Condition The climate varies from place to place with physiographic features. The hilly regions with forest coverage are extremely cool whereas the open lands are comparatively hot. The minimum temperature goes up to 4o C and a maximum of 28 – 30oC in the hilly regions whereas in the plain land, the minimum temperatures ranges 8 – 10oC and has a maximum of 42oC. Winter starts in October and ends till March, summers starts from April and extends till June and monsoons starts from July and ends in October. This climate facilitates two crops during the year. The climate at micro-region is more important for study as the thick vegetation, water body and topography plays a significant role on habitat.

4. Settlement Pattern and Habitat This diversity and independence of tribes has encouraged the development of unique and varied ethnic culture and habitat. Overall, the spatial pattern corresponds to the topographical character of the areas they have chosen for settlement. The settlement pattern varies from tribe to tribe as it is determined by location, sociological circumstances, occupation and ethnicity. The size of settlement is considerably small, cluster size is three to four houses and maximum number of houses in a settlement is 100-150. Tribes follow all together different pattern within the same geographical location and tribes often mingle among themselves. This variation is mainly due to *Corresponding author (Krishna Kumar Dhote). Tel/Fax: +91-94065 18194/ +91 755 2012. American Transactions on 2670562. E-mail address: kkdhote@hotmail.com.

topography, microclimatic condition and their occupation.

At present the majority of the traditional village had undergone changes due to spatial arrangement patterns of the active response of the society. These changes arise from the development paradigm and the new innovations, so that the growth in the field of social, economic and culture is experienced (Alit, 2004; Chiri and Giovagnorio, 2012). However the development in the tribal areas is not at the pace of their urban or even rural counterpart. To analyze the settlement pattern of tribal of tribal areas which are unconsciously planned, function is to be studied as “function is an analogy between social life and organic life” (Mandal, 2001). The tribal communities consists of cluster, all arranged to form a social structure and their inter relation in terms of social contiguity.

One of the major functions in case of tribes is agriculture. They are engaged in ploughing, sowing, and harvesting in the fields and return to dwellings for relaxation. This daily up down movement is either by walking or on carts and creates an intimate relation between house and farm.

During harvesting period they prefer to live in temporary huts built in the field itself and animal yard is also erected nearby (Nath, 1989).

4.1 Typology of Settlements On the basis of morphological study the settlements are classified into three typologies. The typologies are worked on the basis of size and structure.

The first typology is a village

predominantly of farmers. These villages are located on plains and the occupants are mainly associated with agriculture and the average size of village is 1000-1500 houses, Figure 01 represents one such plan. These villages cannot be termed as tribal settlements as the inhabitants are from other communities. Still they are studied as they become the nucleus for the small tribal settlements which are in the periphery at the distance from 2 to 10 km. The growth of village is organic and the distinct impression is made by the road which connects the village with other villages. This road acts as a line of division between the old village and the new development. The old village consists of non uniform dwelling units placed with respect to landform in a manner that the streets allow to drain the rain water during monsoon. While all the public buildings are clubbed

together around open space. This open space is multifunctional. It is the center place where the market, fairs during festival and rituals are performed throughout the year. The clusters of the dwellings along the streets are formed on the basis of ethnicity. The dwelling units of this village are advanced, more spacious and comfortable than that of tribes. The tribal people who are engaged as labors are accommodated in these houses on temporary basis. The streets passing through the farms lead to smaller tribal settlements. In present days, tribal have started building their houses on the outskirts of villages. However the houses are very small compared to that of the villagers.

Figure 1: Settlement typology.1

The second type of settlement is comparatively smaller the number of dwellings goes up to 150. These settlements are satellites of the nucleolus village described above. They are linear i.e. a row of houses facing each other along a street. It is interesting to know that the liner street is not a well conscious effort but the left over space between two houses facing each other, the plan of linear village is shown in Figure 2. The houses are so placed that the street becomes the place of social cohesion and the back yard is connected to their farm. Once the settlement reaches maximum number of houses a new settlement in the vicinity is set up.

Figure 2: Settlement typology 2.

The third typology is of the tribes inhabited in the hilly areas. They depend upon forest produce for their livelihood. They are also engaged in terrace farming. Unlike the tribal living in plain areas their dwellings are scattered (see Figure 3). They lived in clusters of three to four houses as shown in Figure 3 and even these clusters are at different levels at certain distances because of undulating land form. These clusters are not connected by defined pathways as the houses are constructed in the fields itself.

The aspect of sustainability entails use of natural resources, land, water, and forests. In context of development, sustainability refers to optimal utilization of resources whereas tribes are using minimal resources. The land occupied by them for dwelling is limited and keeps on changing from place to place, thus posing no harm to landforms. The settlements have single resource of water which is a river, waterfall, spring or a community well. There is no provision of sewerage in those settlements. The waste water is directed into the backyard. The waste from animals is collected in the outskirts for preparation of organic manure. The nucleus villages, houses people from various communities. It includes people from various occupations to fulfill their needs such as people like carpenter, blacksmith and potter. The festivals are incomplete without the involvement of tribal community. The festivity is the essence of tribal life. The simple and straight community enjoys festivals with great fervor and joy. Music, painting and artifacts have become a source of income for them. Their knowledge about herbs and other forest products is helping in conservation of biodiversity.

4.2 Typology of Habitat Empirical study from tribal groups of India suggests that there are values, integrating into the spatial, social and ritual perspectives and ultimately leading to their habitat. Their lifestyle is amply represented in their dwelling which varies depending upon the location, occupation, community and the micro climate. For analyzing, typologies can be worked out on the basis of spatial configuration, use of materials and building technology & form. However for the sake of simplicity typology has been worked on the basis of spatial configuration. The first type of dwelling unit shown in Figure 4 is habitat type Model-I, which is from the nucleus village. This is essentially the house of farmer and not the house of tribes, who inhibits them. It is the richest in terms of size, hierarchy of spaces and use of material (see Figure 4). This house has an enclosure for protection. It has a formal open courtyard used for social activities, semi enclosed private space which is used for guests, a covered living space which is sometimes two storied and cooking space with rear courtyard. The enclosure which is semi open is used as animal yard. The tribes engaged as labors are allotted one room or allowed to live in the animal yard. The house is elongated along the major axis and is geometrically symmetrical. The roof type is lean to for semi open space and double lean to for covered and private spaces. The inner private spaces are elevated. The central *Corresponding author (Krishna Kumar Dhote). Tel/Fax: +91-94065 18194/ +91 755 2012. American Transactions on 2670562.

place is the highest and sometimes mezzanine floors are also constructed. The walls are 60 to 90 cm thick mud walls. The roofing is done with earthen tiles supported by timber framework. For supporting roof of semi open spaces timber columns are used. The openings have door panels only on the external walls. For ventilation small vents are provided on the external walls.

The second type of house Model-II which is shown in Figure 5 is found in linear pattern and follows the hierarchy of semi open, covered and semi open spaces. In this case the house is elongated along the major axis and there are no openings on side walls. Bamboo baskets or the grain storage made up of mud are used for creating partitions in living spaces. The house is of mud walls with pitched roof with earthen tiles, reeds are used for partitions. For cattle a temporary structure is erected either in front of the house or along the side walls.

Figure 4: Habitat type Model 窶的.

Figure 5: Habitat type Model 窶的I.

The third type of houses, the Model - III is found in clusters. The unit appears to be one rectangular block with a sloping roof. Within the rectangular plan partition walls are erected to separate living from cooking space. The walls are directly exposed to sun and very small openings are provided for ventilation. The plan of Model III is shown in Figure 6. The animal

yard is constructed nearby. In the fourth typology i.e. the Model IV, the plan of which represented in Figure 7 is a house, elongated along the horizontal axis. The spatial hierarchy has semi open spaces adjoining the covered space. The entire dwelling unit is enclosed with walls and in under one roof. The entry is through a semi open space. On entrance a temporary shed is provided or a separate enclosure with thatch roof is provided for cattle. In the third and fourth typology the house appeared to be one unit.

Figure 7: Habitat type Model 窶的V.

The main building material used for constructing the load-bearing walls of the dwellings was adobe, since earth is the most plentiful resource in the region. Adobe units were made of earth, which could be found on site, mixed with straw along with water. Stones were used to reinforce the wall. In the case of houses in hilly terrain where bamboo is plentiful, the walls are made of split bamboos. The walls are often made of bulrushes, maize stalks (Shah, 1943). The roofs are hipped, double lean and lean to roof. The roofing is done with earthen tiles. The earthen tiles are *Corresponding author (Krishna Kumar Dhote). Tel/Fax: +91-94065 18194/ +91 755 2012.

supported by a timber framework. The timber used is crude and undressed, the straws or bamboo strips are used to provide the support to earthen tiles. This make the roof perforated and allows ventilation. The load-bearing walls support the roof frame placed above. The Eaves of the roofs are projected along with the length of the house. This projection protects the erosion of mud wall during rains and also provides sunshade. The temporary structure for cattle is constructed with four wooden post and flat thatch roof; reeds are also used for partition walls. The lintels were of timber planks. For ventilation circular voids were left in wall. Bamboos were used as grill in case of large openings. The mezzanine floor of the dwellings consists of the wooden logs or the beams that bear the wooden floor placed right above the timber ties. They make huge storage bins for grain storage. Generally, the bins are quite tall and square in shape. (Aashi, 1996) Cow dung and mud is applied for finishing and surfacing of flooring and walls. The houses are decorated by painting the figures of animals, birds and vegetation. Relief work is also seen which is done by using rice husk and mud.

5. Sustainable Practices Due to natural physical barriers tribes have little access to the outer world. They seek help from other fellows for cultivation and protection from wild animals. The spatial planning is mostly governed by the social groups formed due to ethnicity, topography, availability of fertile land and shared community facilities like water sources and movement channels.

The

transformation of clusters is an outcome of increase in the number of family members (Hinani et al., 1993). In the absence of external forces, growth in traditional settlements was mostly driven by the daily needs of users and mechanisms that emerged from a symbiosis between the social norms, occupation and religious customs (Besim, 1994; Akbar, 1988).

There has been a considerable amount of research that defines and characterizes the form for a sustainable city, and which urban forms may be more sustainable (Mike et al, 2010). It is a complex issue. The physical dimension may include its size, shape, land use, configuration and distribution of open spaces - a composite of a multitude of characteristics including a city transport system and urban design features. However its sustainability depends on abstract issues like environment, social and economic. It would be unfair to analyze the tribal settlements on above

246

Krishna Kumar Dhote, Preeti Onkar and Santanu Das

parameters as they are not comparable with any urban form in terms of scale, magnitude and character. However the settlements are being analyzed on the five dimensions of sustainability.

These dimensions are physical, social, economic, cultural and environmental. Physical sustainability of the tribal settlements it is evident from the close proximity of their workplace and natural resources most importantly water with respect to their dwellings. The initial setting up of these settlements was in harmony with their bioregion and is being preserved through their community practices. The luminosity of tribal settlements is restricted to day lighting and the orientation of their settlement is such that they get maximum ventilation and minimum solar radiation. The streets are leftover spaces between houses and serves as natural drains. The pattern of the settlement, linear or clustered is derived out of the land form. The structure is legible because of the sizable scale of the settlements.

The tribes or depending upon the agrarians for their livelihood and the farmers depend on tribes for supporting activities, this interdependency leads to social cohesion amongst them.

Music, painting and other art forms are integral part of their life. The festivals, religious rituals and social functions are attended by other communities as well. The settlement consists of persons varied occupation i.e. carpenter, blacksmith and potter making the community self sufficient. Also there exists a group of distinct cultural identity which leads to setting up of a living and working community that reflects the diversity of the settlement and a better social cohesion. The houses facing each other share common community spaces and are a focal point for various community activities raising social value. The economic dependency of the settlements is mainly upon agriculture and forest products and maintains the biodiversity.

The climatic responsiveness in terms of urban architecture can be defined as the satisfied need of human being in terms of thermal comfort, luminosity and acoustics (Maria, 2009). The conventional definition of sustainable architecture may not fit for tribal habitat, the sustainability in terms of tribal habitat needs to be redefined. The present study of tribe revels that the habitat emerged from the complex mix of considerations including climate, economics, socio cultural factors and religious purposes.

dwelling unit reflect the concern for function and indicate other socio cultural characteristics.

(Saleh, 1999).

The climate of central India is tropical. However for thermal comfort, climate and microclimate plays a significant role.

Typically thermal comfort requires low solar gain,

ventilation and adequate natural light in day time. During the night time in winters the heat gain inside the house needs to be retained. In monsoon protection for dwellers as well as the cattle is required. The habitats on plains have moderate climate as compared to the hilly regions. In hilly regions the days are warmer and the nights are cooler. The houses on plains shown in Model I and II follow hierarchy of open, semi open and covered spaces. This helps in reducing the solar gain, in covered areas. The semi open spaces lower downs the temperature of air before it enters into covered spaces. The pitch roof of covered space allows hot air to escape from the perforation and joint of the roofs and creates air draft. The thermal gain in the covered space is retained during winters. The inhabitants prefer to sleep in open courtyard in summers, in semi open areas during monsoon and particularly when the humidity is high and in covered spaces in winter. The open courtyard, low height semi open spaces and covered spaces with pitched roof modulates the air movement. The elongated house plans with minimum internal partitions or partitions created by storage bins, allows an easy passage for cross ventilation. The multileveled floor and the strategic staggering openings help in enhancing the air velocity. On the contrary Model III and IV which are located on hilly terrain have single roof cover and a wall all around the unit. This is done intentionally to catch up the wind of higher velocity. The pitched roof typical in all tribal houses shows an understanding of stack effect. Hot air rises by buoyancy and is infiltrated out via gap in between the earthen tiles.

The projected eaves, semi covered spaces around the main living area and the cattle sheds adjoining the houses reduces the exposure of sun on walls and also protect the mud walls from rains. The ventilators, circular in shape, which are above the lintel level allows diffused sunlight and maintains privacy of inhabitants. In all instances local material was used, the material was used in its crude natural form. The size, strength and bearing capacity of the material was a guiding factor for the structureâ&#x20AC;&#x2122;s dimensions and formulation of spaces. The material used for wall mud, straw, reeds and the earthen tiles or thatch roof provided thermal insulation. The

building material used have definite life period which differ for various material, they need to be replaced periodically. Even the routine maintenance is required, mud floor needs to be plastered daily with cow dung, and the earthen tiles need to rearrange before every monsoon. However, the waste thus generated doesnâ&#x20AC;&#x2122;t have any adverse effect on environment.

6. Conclusion Buildings, as their design and use today contribute to serious environmental problems because of excessive consumption of energy and other natural resources. It is also important that the local building wisdom and culture be explored and the precious heritage of vernacular architectural culture be passed on ( Jun H. L. et al., 2012). The tribal populations in the geographically remote areas are still following the indigenous vernacular style for their settlements and habitat. These habitats provide them the needed thermal and visual comforts at reduced level of resource consumption. These practiced can be effectively adopted and integrated into the present days building design.

The settlement pattern of the tribal habitats suggests that the size should be finite to achieve sustainability. The structure or shape of the settlement should be with respect to the topography.

The natural drains works as streets, the ridges, the valleys and the vegetation affects the microclimate and should be considered before placing the building blocks. The streets and courtyard in between the cluster modulate the airflow for proper ventilation and also reduces thermal gain in tropical conditions. The individual houses donâ&#x20AC;&#x2122;t have sewerage. The waste water from the houses is disposed on the streets which dry up in the sun. The organic waste from the settlement is dumped at one place and is used as manure.

The buildings are oriented to minimize the solar gain during summers ensuring adequate daylight and protection from rains.

The spatial configuration allows thermal comfort and

sufficient privacy and interactive spaces amongst the habitat. The materials used for construction is low embodied energy and provides thermal insulation. The semi open spaces around the core of the building helps in reducing the thermal gain whereas the open courtyards are used to catch the *Corresponding author (Krishna Kumar Dhote).

sun for agricultural related purposes.

The tribal settlements and habitat demonstrate an economical use of native natural building resources, and respond to climatic conditions using eco friendly design principles that provide human comfort. These design principles are consistent with the form, orientation and materiality of the buildings. Their combination of social, functional and environmental reveals life full with color, flavor fervor which, instead of imposing on the nature it emanates from it.

ABSTRACT

Article history: Received April 18, 2012 Received in revised form July 01, 2012 Accepted July 20, 2012 Available online July 25, 2012

The sense of place can only be achieved if the urban heritage is still intact and preserved whilst accommodating for new development. In the past Misurata city center where the traditional areas and historical significance are located did not have any positive consideration and appreciation from government which, were destroyed to build a new commercial buildings within business district area of city center. This paper intends to highlight on urban heritage "historical significance & activity pattern" that still survive in the city center of Misurata and reflects the sense of place. The study adapted the visual survey field method for data collection and this approach adopted techniques namely photograph and diagrams or maps. The results of the study indicate that there are some urban areas and buildings with historical or traditional significance and conducive sense of belonging and identity that must be renewed, restored, reused and conserved; for instance the marketplace, Allfah Square and the old city center.

1. Introduction The concept of conservation touches on the very essence of culture survival. Often defined as maintaining the presence of the past in the present time, it reflects on the need to safeguard the built environment that we inherit so that the future generation are able to appreciate, learned and value their history and the past. Our cities are actually a testimony of our existence and help to build a stronger foundation for the future. The current scene in the development of cities saw a trend towards a bland and uniform modern development reflecting the values and ideals of the modern city.

The historic environment, which comprise of the old and historic buildings,

traditional street pattern, activities and urban landscape provide a local distinctiveness to our city that reflect our culture and civilization. Their presence is so vital to our sense of place and belonging through their uniqueness that gives each city its own identity. Historic environment also provides a sense of stability to the modern society, whose hectic lifestyle needed an environment to remind us of our purpose in life. T he urban heritage consists of all elements that shape the urban fabric including the local people, their activities and way of life. These elements have to be seen in total as they contribute to the character of our cities. Thus conservation efforts must focus on maintaining these qualities so that the whole historic environment is kept as an ensemble. This paper attempts to explore and evaluate the urban heritage “historical significance & activity pattern” that still survive and reflects the sense of place, identity and culture value in Misurata city. The significance of such investigation is that conservation of our urban heritage and buildings of historical significance or areas with tradition or social aspects is one main elements to ensure city characteristics and provide a sense of place that relate to sustainable design. This paper is based on a study that investigates the physical features and activities pattern in Misurata city center and Trablus Street in order to determine the qualities which are conducive for place character and sense of place.

2. Concept of Sense of Place “Genius Loci" The term 'place' is very rich and has geographical, architectural/physical and social connotations (Canter, 1977). Canter (1977) suggested that a place is a result of the relationship between actions, conception and physical attributes. The geographical concept of place refers to the aerial context of events, objects and actions. This includes both natural elements and human construction in terms of materials and ideals. The concept of ‘place’ also refers to the integration

254

of elements of nature and culture and interconnected by a system of spatial interaction (Relph, 1976).

Place means more than an abstract location, it is totally made of concrete things having materials, substance, shape, texture and colour. All these things determine the character and the essence of a place. It is an area where perception is enriched and a person is made aware of the distinctive character of specific localities. Sense of place is the ability to recognize different places and different identities of a place. This concept incorporates imageability, topophilia, attachment and symbolic meaning of places (Relph, 1976). The search for a sense of place permits individuals to relate spatially to the aspects of the urban life they specifically choose to identify with (Banz, 1970). In theory gaining a sense of place means that a person can orient himself in his environment by using all his senses. The ability to acquire a sense of place depends on the degree of familiarity a person has with the place. Since sense of place comes from the attribution of meanings to physical forms, place is affected by people and in return people are effected by places. As a result, there is an interaction with a place rather than a response to place and endows the place with meanings. This is why old and historical places have more sense of place than newer places.

In fact, places that do not relate to any particular period and which are lacking a sense of continuity are uncomfortable environment. Thus, the stability and continuity of an environment act as a therapy to the rapidity and scale of modern social and environment changes. People who are satisfied with their environment will also develop a collective motivation to retain its qualities, where those who are dissatisfied with their habitat may relocate or opt for improvement (Downs & Stea, 1973).

3. The Concept of Urban Heritage Conservation Conservation “means all the processes of looking after a place so as to retain its cultural significance" (Burra Charter Article 1.4). “Conservation encompasses the activities that are aimed at the safeguarding of a cultural resource so as to retain its historic value and extend its *Corresponding author ((Ibrahim Abdallah Shinbira).

physical life. There are conservation disciplines that address different kinds of cultural resources.

All share a broad concept of conservation that embraces one or more strategies that can be placed on a continuum that runs from least intervention to greatest; that is, from maintenance to modification of the cultural resource. All operations are designed to understand a property, know its history and meaning, ensure its material safeguard and, if required, its restoration and enhancement.

The term 'heritage' is used widely in a variety of contexts. Traditionally, the word 'heritage' relates to the natural environment, buildings and monuments, the arts, social customs and traditions.

Man's contribution to the natural environments has resulted in buildings and

monuments of significant historical value, which can be broadly termed 'the built heritage'.

According to UNESCO in 1972 conference the heritage is classified into two categories; firstly the Cultural Heritage, which involves a monument, group of buildings or site of historical, aesthetic, archaeological, scientific, ethnological or anthropological value. Secondly, the Natural Heritage, outstanding physical, biological, and geographical features; habitats of threatened plants or animals' species and areas of value on scientific or aesthetic grounds or from the point of view of conservation (UNESCO, 1972).

Building conservation generally involves the

renovation of old structures, which could bring them back to fulfilling their original function by contemporary standards or adapt them to new uses.

Sometimes a building could be stripped

down to its historic faรงade to act as frontispiece for a new function space. "Urban culture indicates human heritage. It gives worldwide reasons for living in congested cities. Aesthetic is basically for human pleasure while historical quality need to be determined through careful analysis.

The aim of urban heritage conservation is to retain its character" (Nahoum Cohen,

2001). Montgomery (2001) argued that all good cities have distinctive identities and character.

4. Background Over the past four decades Libya not only has witnessed tremendous missing in terms of urban heritage conservation, but unfortunately has witnessed also the destruction of some of the buildings or sometimes a whole area that organized as a traditional, historical, significance and cultural values. In 1980s the government decided to bring down the ancient city of Misurata and rebuilt commercial tower blocks. Since the historic core is strategically located in the hub of the Central Business District, they have been the focus for speculative commercial development and subjected to intense pressure for change (Figure 1). Currently, there are some colonials buildings and other areas such as the marketplace that reflects the social interaction and activities which faced the destruction during the war in the Trablus Street and other areas (Figure 2). These places mentioned are the historical or traditional core that contributed significantly to the sense of place in Misurata city, which must be considered in future for any development or reconstructions through the architectural qualities, townscape and exciting activities that provide the life and charm of our cities (Figure 3).

5. Method This study is based on two main categories below (Figure 4): 1. Literature review which describes some point of views that relate to the urban heritage, place, conservation and urban design. This is to obtain a theory synthesis about urban heritage conservation and sense of place.

2. Field survey which applies the theory synthesis to the real condition of place or city. This is to know the opportunities that ensure sustainable design for future development and conservation of the city character.

6. Discussion 6.1 The Threats The value of historic environment lies on its authenticity and the way in which its fabric is kept intact. The historic core contributed significantly to the sense of place in our cities through the richness of its architectural qualities, picturesque, townscape and exciting activities that provide the life and charm of our cities. It is also the place that reflects the true culture and the people and their presence has influence on the survival of the culture. A study of the old town centers in Libya that dated from 1980s until now revealed a lot of worrying trends that threaten the life could possibly lead to the death of our historic environment. These threats can easily by categorized into the following groups:

6.1.1 Disruption of the Urban Pattern The historic core unique urban pattern of fine grain even texture has been disrupted by the invasion of the office tower blocks and residents blocks by altering the grain and texture (Figure 5). The danger of allowing large scale commercial development, if not designed sensitively, within the fabric of the historic core is that they might act as a cancer that could in the end destroy what still survive from the fabric of the historic environment. This is because such *Corresponding author ((Ibrahim Abdallah Shinbira). Tel/Fax: +218-0512762646.

development may attract insensitive speculative development and inflating the land values within the city center of Misurata. This will make the historic and traditional buildings no longer economically viable to be located where they are at the moment.

Figure 7: New development is alien to traditional shops in terms of architectural qualities, scale and proportion.

6.1.2 Disappearing Townscape The unique townscape qualities of the traditional architecture, social activates and their human scale are lackluster and slowly going to disappear as a result of modern development encroaching into and within the vicinity of city center of Misurata. In addition, many original buildings were destroyed through insensitive set-back policies with intention of developing the city during the last thirty years (Figures 6 &7).

6.1.3 Changing Activity Pattern The charm of the historic environment is to a great extent due to the variety of activities taking place, enriching our sensory experience of the townscape through the stimulation of colours, smell, sight, sound and moods. The market related activities can still be seen in the old city center such as Sog Allfah, narrow roads market in center core and the marketplace that is located in Tubules Street reflect the true nature of our society which must be considered by conservation efforts (Figures 8 & 9). However, these activities are facing tremendous changes by the policy of large scale commercial buildings development which makes the area disrupted by traffic jam, car park, townscape disappearing and changing activities pattern (Figures 10& 11).

6.2 The Prospects There is no denying that conservation of the urban heritage has significant impact in giving a place its identity. The meanings often associated with familiar and historically significant places provide a sense of stability and security to urban dwellers. These qualities are important to secure the cultural survival of a society. Still, it could be questioned at what cost, considering the heritage value of the activities that occurred there before.

Figure 12: Buildings in the historic center, does not get any conservation efforts. Sog Allfah 6.2.1 Increase in Tourist Attraction and Revenue The economic gain of conservation efforts can be seen through the increase in the tourist attraction of the historic and actions that reflect culture and social activities of the city as is observed in old Tripoli (Figure 12). It is a widely accepted knowledge that historic environment has a tremendous attraction to tourists who are more interested in the local culture as compared to its modern counterparts (predominantly international style). Thus through conserving the historic fabric and the urban heritage, revenue can be achieved if the environment is conserved whilst accommodating to the tourists' needs for services and facilities.

Over patronizing the historic

quarters by tourists should be avoided at all costs as it can destroy the sense of place, which attracts the tourists in the first place. This calls for effective urban managements and planning for the tourism industry when dealing with historic environment.

6.2.2 Providing Life to Obsolete Building Stocks The derelict buildings in the historic quarter can be seen through restoration of these building and adapting it into the use that could benefit from the presence of the tourists. Such projects not only provide new life for these old buildings but also has the added value of being of historical and architectural significance to the city (Figure 13). This value is not found in new buildings, as

262

Ibrahim Abdallah Shinbira

meanings and associations are stronger in buildings that have been around for a long time and thus become a familiar part of the environment for the residents.

Conservation projects, if conducted in the manner can easily turned a blighted area of dilapidated buildings into a vibrant and charming place in the city center. The beauty of conservation as opposed to preservation is that it is looking for new ways to ensure that the historic environment becomes relevant in the modern times.

Figure 13: Restoration and rehabilitation can be helpful to consolidate the old city center core of Misurata, to relive the sense of place and to keep the inherited features for new architecture.

7. Conclusion The challenge that we faced is to ensure that future development of the historic quarter will not destroy the heritage value that gives the places its uniqueness and heritage value. This can be done by adopting a sustainable approach when dealing with development in places of historical, architectural and cultural significance. Sustainable development can be defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

This involves the protection of not only basic resources but also the

cultural heritage and thus conserving this environment will be leading towards a sustainable environment for the future generation.

A sustainable approach in conserving the urban heritage means that the interrelationship between historic environment and the natural environment and between these and wider economic and social issues will be given due consideration.

This environment can be resulted

from particular activities or from attractive historic, culture, architectural, landscape or townscape features. Area with an attractive character and strong sense of identity or sense of place must be maintained, conserved and enhanced and, where practicable, other areas are upgraded to provide an improved sense of identity and place. *Corresponding author ((Ibrahim Abdallah Shinbira).

ABSTRACT

Article history: Received April 15, 2012 Received in revised form July 01, 2012 Accepted July 15, 2012 Available online July 25, 2012

Function should always be regarded as the most important subject before the consideration of form and space be fulfilled. The design reaches its level of aesthetic when it is able to integrate all the required relationships in the design process with clear objectives. This can be seen clearly in the case of mud clay architecture in Hadhramout region, Yemen. The issue of material durability, traditional construction techniques, beauty, and affordability becomes the crucial factors that will be able to fulfill the user’s level of satisfaction, comfort, financial, and spiritual needs. Based on the architectural knowledge gained over the years, the Hadhrami local master builders have acquired brilliant skills and expertise to shape the regional environment and architectural heritage. They always consider ‘functional spaces’ before the buildings and houses are erected. This study investigates the use of mud clay architecture in relation to the design of the building function with its specific architectural form and space in Wadi Hadhramout. It focuses on the residential and religious buildings.

1 Introduction Architecture is a subject dealing with building design of form, space and function, which enables to portray the design with the meanings of cultures at specific socio-economic activities, technology, place and time. Architectural work is seen as a function that comes first as a design and any spatial architecture designed must meet this function. Design is the ability to set out the required elements in specific and clear relations. This was seen clearly in rooting in and carrying out the artistic environment in Hadhramout Valley. The environment has achieved functional and artistic perfection in organizing the buildings to suit human standards. However, the Hadhrami has produced the instinctive sense to measure things. Measurement was known even in the past in different civilization like using parts of the human body, such as the arm as a measurement unit.

Rhythm is considered one of the main bases that lead and connect the architectural structure of the buildings. This reflects on repeating certain artistic architectural elements such as structure, vents and vertical sequent storeys. These architectural elements can be built up in mud for many houses’ facades. The Yemeni architecture in general and the mud architecture particularly in Hadhramout Valley have their uniqueness of employing the natural elements from the surroundings and the heritage. The style is very distinctive in Yemen which is different from other parts of the world in its creative value, architecture and shape. Researchers considered the style as unique and a valuable edifice. It has a rare status in smooth shaping of multiple structures, patterns and functioning harmony in interior spaces. The Hadhrami architecture exemplifies a typical style for human beings living creatively and effectively with the surroundings. The Hadhramies through different ages managed to succeed in making constructional and architectural compositions and to find out a matching environment to appropriate the Hadhrami and his regional surroundings. In fact, he has really managed to create different styles to surpass the world ones. The traditional architecture and construction go very well with the surroundings and meet the functional aspects; they also go with the religious nature of the inhabitants. Creativity has become part of the Yemeni architects’ concern in terms of incorporating the terrains with his design, employing the raw materials and building techniques available. In his design, he takes the four seasons in the region into his consideration for a convenient housing design with provision for human needs, for instance, proper housing, work, worship (Al-Muqatri, 2000). The mud-brick high-rise buildings in Shibam, built in cluster pyramid by a city wall exude the genius of Hadhrami architecture. Today Shibam is recognised as one of the heritage site under UNESCO’s World and construction heritage lists, and

it won the 2007 Aga Khan Award for Architecture which is the world’s largest architectural award.

As a result, the study is important to search for architectural design elements that can be integrated in the development of space planning design in Hadhramout region. This paper studies the elements of the historical and architectural value in its diverse architectural layout styles. The architectural space and its relationship to form based on a specific function are significant to the Hadhrami architecture which has artistic designs of mud clay buildings. The architectural spaces in mud construction in Hadhramout Valley will be implemented by using different architectural styles.

2 Interior Space Shaping in Mud Buildings The Hadhrami architects took the interest in the interior space and function and treated them in different ways, and they found out solutions which improved the buildings. They also indicate that they progressed in conformity with the traditional methods accumulated cognitively and culturally over the years. It is also noted that Hadhrami architects gained transcendent ability that qualified them to deal with time and place variables. They had the way to form the functional spaces that were more convenient to the environment (the nature and the society) (Al-Shibany and Al-Madhajy, 2000). Space and volume arrangement in mud buildings was made in accordance with the shape and volume of the building on the basis of the functional and environmental requirements. The building layout has also been made taking into account the religious believe of its occupants. These factors can be clearly observed in the interior space layout of the buildings that inherently tackled the weather problems. Such a combination of natural materials along with a layout that suits the different requirements mentioned above is a good example of dealing with the different environmental and climatic factors by controlling the function at the design and construction level. Comfortable temperatures could be maintained inside the building through proper selection of natural insulating construction material and through control over the flow of air currents via narrow openings located near the top and bottom of the interior spaces. The trend of the architectural design resulted in buildings that are of closed nature and vertically expanding in order to cope up with the requirements of the increasing number of big families. Type of spaces decided the nature of the ornamentation being used inside and outside the building.

patterns are used decorate the frames of windows, doors and frames of different woodwork. Mud builders are characterised by homogenous and monotonous texture with respect to height, mass, balconies and the bridges elements between the buildings. Exterior walls of mud buildings are constructed in such a way as to give a tapering shape (wide near the bottom and relatively narrow near the top) to the building when looked at from outside. Upper stories and roofs are lime washed and projections are provided as shading elements and protection against rain water. As far as proportions are concerned, the buildings form masses and plane areas with opening in the facades.

The buildings are not symmetrical in plan and the exterior elevations are neither dependent on symmetry of mass nor shape of the architectural elements. Elements of residential, service and religious buildings differ depending on the function to be achieved. The layout (Figure1) may be formed of square, rectangular or compound masses discerned by the unique Hadhrami building style in terms of elements and decoration that reflect the ancient Hadhrami and Islamic art and architecture (Damluji, 2007).

Figure 1: Plans and Interior Spaces of the Houses

3 Scale Scale has been used by Hadhrami since ancient times when they dealt with different objects and their relative proportions as can been seen in the old mud buildings. The "arm" is used as a measuring unit in buildings and the "mutaira" used as a land measurement unit. Use of projections in some of the upper parts of buildings facing the side alleys result in shading of parts of the exterior walls and impart a perspective dimension from an optical point of view (Figure 2). The

268

facades themselves are overlooking the street or a public square or an alley so as to facilitate sufficient lighting and ventilation, and to provide a good view of the public space, without exposing the interior of the neighbouring houses to view or threatening the privacy of their inhabitants. These windows are generally distributed in such an organized fashion in the facade so as to avoid placing the openings in the side walls of neighbouring houses since the houses of Shibam are either attached or extremely close to each other. The distribution of these windows follows an organised and traditional pattern. Hence, in the ground and the first floors, only small openings are present, while wide ornamented and glass-free wooden windows are used beginning with the Mahdarah (men's reception) on the second floor. The visitor also notes that in order to allow large and numerous openings in the windows in the facade, screen windows consisting of networks of geometric and floral patterns, made of local ilb tree, are fitted in and assembled in a variety of compositions.

4 Colour The colour is the most important and inseparable aspect of material and its characteristics. It is considered one of the advanced aspects of the material that has an influence on its size, rate and shape. The colour is an essential element in the architectural composition and its sense. It is an indispensable part in architecture and its relation with volume and space and it has a great impact *Corresponding author (Anwar Ahmed Baeissa) H/P 00967734066823 Email: anwarbaesa@yahoo.com.

on the shape of the architectural elements. The outside colours of the mud house were often obtained from the raw material available in the surrounding environment. The particular usage of the whitewash for the mud houses was based on its climatic task related to the temperature and light. It is also noted that there is a colour harmony in the mud houses. The mud colour and the decoration of the windows and doors and the white colour used over the doors and windows create a contrast between the light and dark colours. This contrast creates in turn a visual effect that makes the viewer feel lively and vigorous and this also helps clearly emphasizing the visual decoration that produces a genuine and unique expression of architecture.

5 Elements of Clay Building Among the interior elements of a Hadhrami house unit are the doors, the windows/ Mashrabiya and the interior walls, the holes in the walls (vents), the railings and the security bars, the columns and the beams, the roof-design, the ceiling-design, and floor-design, the spaces for males and females, and the orientation to the Kiblah. The wooden doors that are mounted in the front facade of the buildings are differentiated by their grandeur and by their thickness. For most houses, the main door of the building is its only access. In the wooden frame at the top of the door the date of the construction of the building is engraved.

5.1 Loading Bearing Walls The exterior of the building takes a pyramid like shape with the exterior walls being tapered.

The building is wide at the base and narrows towards the top. The idea of mud walls generally depends on selecting the proper type of soil that when mixed with water and given the desired shape result in a storing solid entity. Proper bond of the mud blocks is achieved through either natural drying process as is the case with Adobe which is sun dried before construction or through in-situ drying of mud (soil and water mixture) as in the case of cob (Midamk).

5.2 Columns Columns are called (Sahm). They are classified as wooden, stone or mud columns. The interior columns supporting the roof are made of nabk wood. Mud columns (Madar) are circular or rectangular in cross-section. Diameter of circular columns ranges from 30 cm to 70cm. Size of the columns depends on the desired function inside or outside the building. Circular columns are widely used in the yards (portico) of mosques. The capitals (the upper part of these interior

270

columns) (Figure 3) of these wooden columns have the same forms. Usually they are in a simple rectangular cross-section and several carved protrusions. In appearance they are almost similar to the capitals of the columns used in the prehistoric civilisation of the Arabian Peninsula and Persia, especially those capitals carrying the heads of two arms. These are known as kabsh meaning ‘ram’ in Arabic although birds or pigeons may be seen in some other cases.

Furthermore, a large percentage of cylindrical columns with circular cross-sections, and columns with square cross-sections, are built from madar or stones. These are moulded from madar or cut from stone in circular and semi-circular forms for that purpose. They are then smoothen up and covered with a layer of mortar (mulat) to look like one homogeneous piece. Some of the capitals of these columns are similar to the base of the square Islamic columns; in the others especially in the case of the capitals in the palaces (such as in Tarim and Sayion) which were built around the turn of the century and which were influenced in their details and ornamentations by the classical Western civilisation, they have the form of classical Doric and Ionic Greek columns.

Figure 3: Columns of the House.

5.3 Stair Walls Beings an important element of the building, this column is called the "bride" (arus). It is constructed from square or rectangular mud blocks (120cm x150cm). It is attached to the stairs leading to the upper floors and raised to match the height of the building. The stairwell (Figure 4) is located centrally around arus, a vertical column near the entrance forming the main support for the *Corresponding author (Anwar Ahmed Baeissa) H/P 00967734066823 Email: anwarbaesa@yahoo.com.

271

storeys of the building stretching vertically through the building to its upper floors carrying the stairs around it. The height of the ground floor ranges from 4-5 meters (13-16 feet). There are one or two additional basement storeys, known as khann. This is accommodated in order to take into account the variation between the main street level and the level of the city's raised site.

Figure 4: Sections and Stairs of the Houses

5.4Â Arches Closing narrow and long areas is the main function of arches in mud building of Hadhramout valley. Sometimes branches of green trees are used to temporarily support the arches; these branches are taken away after two or three months when the roofs have dried out. The master-builders build the rows of the bricks over the thresholds using the traditional way until they reached the level of the ceiling. The Arched Ceiling Construction (Figure 5), is an expression (jamlul, or yamlul) which refers to the method used in constructing arched ceilings or vaults. This method is composed of laying the brick (madar) in a circular or spiral pattern, when constructing a dome, or arranging them in the shape of an arch stretching longitudinally. When constructing arched vault (aqd), the entire three-dimensional arch receives the shape of a segment of a circle, less than a semi-circle. The jamlu then, does not relate to the details of the building method itself, but rather to the method in which the interior and exterior walls are vaulted. Usually, the construction of the ceiling is carried out when the builders have completed the task of constructing the first floor. They either lay the wood (ud) for a flat ceiling or employ the method arch (ukuf). The arched ceilings can be in the form of domes or vaults (jalabab), operating in length. Jalabab and ukuf are expressions locally used to refer to that (Baeissa & Hassan 2006).

5.5 Windows Ventilation and lighting are the main functions of the wooden windows in mud buildings of Hadhramout valley. Location of windows takes into account the social aspects and life style such as provision of privacy. Windows are generally located on the facades of buildings facing the main road and interior open yards. The windows contain screens of beautiful geometric figures that limit entrance of the sun light and regulate the movement of air currents inside the building. Coloured glass is widely used in windows of buildings of Seiyun and Tarim nabk wood is in making the windows. The windows (Figure 6) are small and they are constructed close to the floor, and usually decorated as well as carved in latticework screens with wooden frames and shutters.

windows, many small rectangular openings are designed to allow the light in when the lower shutter is closed. Here a plain mat, made of plaited palm, may be placed on the floor while wealthy people may placed camel-hair rugs striped in rust-brown, white and black. Hard cushions are often placed against the walls for relaxation. The distribution and arrangement of the windows on the external facades of Hadhrami houses add a special aesthetic character to the buildings as a whole.

The main windows of each house are articulated over the main facade of the house. The facades themselves are overlooking the street or a public square or an alley so as to facilitate sufficient lighting and ventilation, and to provide a good view of the public space, without exposing the interior of the neighbouring houses to view or threatening the privacy of their inhabitant.

Figure 6: Facade and Decorative Window of the Houses

5.6 Light­Openings "manwar" or "shammah" In general the type of openings (Figure 7) used in Hadhrami architecture can be seen in the ground floor which contains the main entrance and the spaces for grain stores. The walls have small ventilated holes; also there is a little hole (mannor) near the stairs for air movement (ventilation) and temperature. The stairs rally around a huge pillar near the entrance that forms the main support for the house. They are designed to stretch vertically inside the house, from the ground floor up to the roof; and they are usually adjacent to the stairwell, sharing a wall with it, and providing it with light and ventilation. The ground floor layout provides efficient lighting from the Al-Shammasah from Shams (the sun) which provides ventilation and the interior temperature of the house. Vents provide the space with ventilation and interior lighting for the house and extend on the length and

height of the building vertically from the ground floor to the last floor which intervene rectangular long small holes. In various locations across the length of the Shammash, there are small longitudinal and rectangular openings made out of mud known as Khaysh, differing in their forms and ornamentations, which are usually a simple repeated pattern of squares, triangles or circles.

The longitudinal and narrow, or circular openings called the Al-Ukrah is for ventilation purposes.

Mostly they are located at the upper end of the walls of the ground and first floors, near the ceiling; but sometimes they are inserted between the openings of the large windows or above them, for the purposes of ventilation and lighting (Damluji, 1992).

Figure 7: Openings at the Interior Walls, Shammash.

5.7 Doors The wooden doors (Figure 8) that are mounted in the front facade of the buildings are differentiated by their grandeur and by their thickness. For the most part, the main door of the building is its only access. In the wooden frame at the top of the door the date of the construction of the building is engraved. Generally the doors are impressed and dovetailed, as well as adorned with enormous iron nails and famous wooden bolts in two parts (galudah and gayshamah), which can be unlocked by wooden keys (iqlid). These wooden keys are also made by the carpenters and may have some simple pattern. Baeissa and Hassan (2005) also notice that the keys and locks come in different sizes according to the sizes of the exterior or the interior doors. The most magnificent doors are found in the popular traditional and customs museum in Sayion. These doors are loaded *Corresponding author (Anwar Ahmed Baeissa) H/P 00967734066823 Email: anwarbaesa@yahoo.com.

with geometric ornamentations and Arabic calligraphy, and made with a precision and skill approaching excellence. They further noted that contemporary local doors cannot match the articulate eminence of exquisiteness attained by the old craftsmen, regardless of the fact that the present day artisans in Al-Sahil perform their carpentry and wood work in the same way as their predecessors had done many years before. Doors are made of nabk wood and are generally characterized by their thickness and beauty of the ornamental work and the artistic Arabic writings.

Figure 8: Decorative Doors of a House

6 Ornamentation The prominence of the skilful ability of the Hadhrami architect, which is built from one substance and two designations as well as technical constructions, made up the occupations for its need and functions to provide comfort and relaxation. Its strength reflects spiritual desires through its beauty. This is because of the production of the profound perception in the way of making up architectural occupations between the perception and awareness that deals with changes, place and time. In addition to this, it provides characteristics of specific and changeable places, climate and social settings. On the other hand, the changeability of time, specific effectiveness, as a result of the same belief and social harmony and the Hadhrami spiritual traditions in different regions are all attractions that make Hadhramout a unique place to live. There are several beautiful palaces, buildings and mosques built of mud with beautiful ornamental and decorative works that consist of different geometrical and botanical shapes. These elements reflect the high class of art work of its performers. Ornamentation has been widely used on walls and facades of old buildings in the form

276

Anwar Ahmed Baeissa

of carved patterns and engraved writings. Such kind of work was also used to decorate windows (Figure 6), doors (Figure 8), wooden columns (Figure 3) and mud columns. Decoration has always been used in mud buildings as an element to express the importance of the building and to highlight its beautiful aspects.

7Â Domes A dome is a structural element of architecture that resembles the hollow upper half of a sphere.

The dome (Figure 9) has taken on a defining role in the organization of interior and exterior space in the built environment and developed a high level of specialization by types. Domes are usually used in the Hadhrami architecture in the ground and first floors of the buildings. Domes have been widely used in mud building and became one of its distinguishing elements, especially in mosques and tombs. Semi spherical domes have also been used and constructed by placing clay bricks (madar) of circular shapes during the construction of domes. When these have been built, the walls of the upper floors are then built. The extreme thickness of the walls in proportion to the height of the dome is another indication that these chambers stood at the beginning of the series. Hadhramies used the domes as mosque, tomb and palaces roofs.

ABSTRACT

Article history: Received April 20, 2012 Received in revised form July 03, 2012 Accepted July 24, 2012 Available online July 25, 2012

Sustainable development is a widely accepted strategic framework in city planning and urban green spaces have an important role in it. Beside, increasing empirical evidence indicates that the presence of natural areas contributes to the quality of life in many ways.

Also, urban nature provides important social and psychological benefits to human societies, which enrich human life with meanings and emotions. In order to exemplify the importance of urban green spaces for sustainability this paper analyses some historical Persian gardens for environmental sustainability and citizens’ well-being. In this study, historical Persian Gardens were chosen due to their historical background as first sample of Iranian urban green spaces which are still being used successfully. Some results of a survey conducted among visitors of historical gardens in Iran are presented and discussed. The issues investigated people’s motives for visiting gardens and the emotional dimension involved in the experience of nature and its importance for people’s general well-being.

1. Introduction Theory of sustainable architecture and urbanism is one of the contentious fields of architecture. The idea of sustainable architecture is offered to answer the questions about quality and types of relationship between design and environment. Sustainable architecture is a responsive and active design toward environment and place features and conditions. Sustainable architecture uses its ecological capabilities to create a suitable and desirable environmental condition. It includes a mixture of aesthetic, environmental, political, social and moral values. Some studies on the subject indicate that the concept of sustainability has a root in old customs and traditional cultures of mankind. Therefore, traditional architecture are recognized for considering cultural and social identities and help a great deal in creating social, environmental and economical sustainability. So, traditional aspects were considered in sustainable design philosophy.

Furthermore, sustainability is also a widely accepted strategic framework in city planning and urban green spaces have an important role in it and considered as one possible step towards creating sustainable urban environments (Costanza et al., 1997; Jongman et al., 2004; Opdam et al, 2006; Jongman, 1995; Zhang and Wang, 2006). Also, open green spaces are of a strategic importance for the quality of life of our increasingly urbanized society (Miller, 1988; Chiesura, 2004). In fact, increasing empirical evidence indicates that the presence of natural resources (i.e. urban parks, gardens and forests, green belts) and components (i.e. trees, water) in urban contexts contributes to the quality of life in many ways.

psychological, and social health of people and community have been emphasized by various researches (Takano et al, 2002; St Leger, 2003; Maller et al, 2005). Physically and psychologically, view of natural scenes or elements foster stress recovery (Ulrich, 1981) by evoking positive feelings, reducing negative emotions, and blocking stressful thoughts and provide a sense of peacefulness and tranquility (Kaplan, 1983) and resulted in mental (Hartig et al., 1991; Conway, 2000) and physical health (Godbey et al., 1992). Therefore, local people consider urban nature and daily outdoor recreation opportunities to be the main factors that enhance their every day well-being (Eronene et al., 1997) even if used occasionally (Solecki &Welch,1995; Thompson 2002; Tinsley and Croskeys 2002; Chiesura 2004; Krenichyn 2004). Socially, nature can encourage the use of outdoor spaces, increase social integration and interaction among neighbors (Coley et al., 1997) which lead to trust, mutual understanding, shared values and supportive

behavior (Loures et al., 2007). So, natural areas provide social, psychological and physical services, which enrich human life with meanings and emotions which are of crucial significance for the livability of modern cities and the well-being of urban dwellers which is a key component of sustainable city.

Besides the aforementioned, the functions of urban nature can provide economic benefits for both municipalities and citizens. Air purification by trees, for example, can lead to reduced costs of pollution reduction and water purification, wind and noise filtration can lead to microclimate stabilization. Furthermore, aesthetic, historical and recreational values of urban green spaces increase the attractiveness of the city and promote it as tourist destination, thus generating employment and revenues (Chiesura, 2004).

In order to exemplify the importance of urban green spaces for wellbeing of citizens and for the sustainability of the city where they live in, this paper analyses some historical Persian gardens.

In this study, historical Persian Gardens were chosen due to their historical background as first sample of Iranian urban green spaces which are still being used successfully. Beside, historical Persian gardens are one of the well-known traditional methods in hot arid regions of Iran which play a role in works of beauty and aesthetic as well as compensating poor humidity to create a sustainable micro climate for human living.

2. Making Cities Sustainable Nowadays, increasing in population, urbanization and the impact of urban areas on global environment mean that creating more sustainable urban areas is essential to sustainability (Ozdemir, 2007). Now, the question is: what is a sustainable city and how we can make a sustainable city?

Whereas, there is no acceptable definition for sustainable city; therefore, the concept of sustainable development which includes aspects of urban planning and community development is considered for cities sustainability. According to Bruntland commission (The World Commission *Corresponding author (R. ROSTAMI). H/P: +06-177187197 E-mail address: 2012. American Transactions on Engineering & raheleh.rostami@yahoo.com.

on Environment and Development, 1987) sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs’’. Also, Sibley (1998) stated that sustainability refers to “the continuing ability of the planet to meet the needs of its living inhabitants”. So, some cities have been developing their own sustainability indicators and aspects such as “amount of public green spaces per inhabitant”, “public parks” and “recreation areas” which are often mentioned as important factors to make the city livable, pleasant and attractive for its citizens (Chiesura, 2004). But, from another point of view, developing more sustainable cities is not just about improving the abiotic and biotic aspects of urban life, it is also about the social aspects of city life, that is about people’s satisfaction, experiences and perceptions of the quality of their everyday environments and quality of life issues are central to all.

To reach these goals, it is essential to follow all dimensions of sustainable development (environmental, social and economic). According to principles which were presented in The European Landscape Convention in Florence, 2000; to achieve sustainability, development should be “based on a balanced and harmonious relationship between social needs, economic activities and the environment”. Researchers (Beck, 1992; Sachs, 1995, Ferris et al, 2001; Loureset et al, 2007) claimed that urban landscape can be very positively linked to sustainability policies.

Thompson (2000) indicates that sustainable development seems to offer “landscape architects a tangible way of relating their aesthetic, social and ecological values”. Urban green spaces benefits urban communities environmentally, aesthetically, recreationally, psychologically, socially and economically (Grahn, P., 1985; Burgess, J., Harrison, C., Limb, M.,1988; Conway, H., 2000; Gehl, J., Gemzoe, L, 2001). Once more, urban green spaces are considered as key components in urban sustainability.

3. Material and Method Both, secondary (literature review) and primary data collection have been gathered. Primary data have been collected through a survey conducted among residents of two historical cities of Iran where, a lot of historical Persian gardens still exist and being used actively by urban residents.

To find the most popular and memorable garden among the existing samples, a pilot test was undertaken based on residents’ preferences. The pilot test concluded Hasht Behesht Garden or/ Bagh-e- Bolbol (literally: Eight Paradise Garden or/ Nightingle Garden) which dating back to

1660, in Isfahan city and Shahzdeh Garden (literally: Prince garden), which is created in 18th century, in Kerman as the most frequented.

Respondents were randomly selected among visitors of gardens from various age groups.

Also, personal attributes like gender, occupation, and educational background were considered.

Respondents were asked to fill the questionnaire during their stay in the gardens, so the answers would reflect their immediate experiences. Questionnaires were distributed on weekdays and weekends, in different hours of the day, and in different parts of the gardens. Responses formats were either closed (multiple choices) and open ended. The questionnaires addressed a broad range of issues, ranging from motives for respondents to visit gardens, their activities during visit periods and their feelings towards the gardens. Both descriptive and inferential techniques have been used to analyze and interpret the answers.

4. Results In total, 252 respondents took part in both cities. Sample includes 152 respondents (60.31%) in Esfahan and 100 respondents (39.68%) in Kerman. In total, male gender constitute prevalent respondents (57.5%). Age classes ranged from below 10 years old to over 60 and prevalent by 20-30 age groups (48.0%). Most of the respondents had university degree and categorized as student in occupation. The mean of living period in cities is about 23 years (S.D = 16.16).

4.1 Motives for Visiting Gardens To calculate the data about people’s motives to visit the gardens, respondents were asked: “Why do you visit this garden?” The following alternative options were given: I visit this garden because of its nature and vegetation, its diversity, its beauty, it’s fascinating, its restorativeness effect, its accessibility, its silence, its familiarity, its representativeness and others. A frequency analysis of people’s motives to visit gardens showed that gardens nature and vegetation achieved highest percentage (54.4%) among other options (Fig. 1). This motive reflects the need of natural environment in urban context.

Figure 1: Motivations of gardens for visitors: Frequency distribution.

Beauty of gardens stands out as second most effective factor for 42.9% of respondents. This motive revealed the relation of aesthetic attributes and people’s preferences and emphasized the effect of aesthetic on preferences like other researches (See: Nasar, 1983; Lothian, 1999; Kaltenborn & Bjerk, 2002; Parsons & Daniel, 2002; Hidalgo, Berto, Galindo, and Getren, 2006).

So, gardens became fascinating for 29% of the respondents. Also, aesthetic attributes can affect place’s restorativeness (Kaplan and Kaplan, 1989; Kaplan, 1995; Hernandez, Hidalgo, Berto, and Peron, 2001; Staats, Kieviet, and Hartig, 2003; Koole, Vnder, and Wulp, 2003; Galindo and Hidalgo, 2005) which was mentioned by almost 28% of respondents. Restorativeness effects of gardens can create a place for relaxation and step away from daily worries, breath fresh air and relax mentally and physically.

Garden’s open view and easy accessibility were cited by almost 24% of respondents. Findings also, indicates that 18.3% of respondents visit garden because of its visual diversity and because it is a representative place of the city. 62.7% of respondents mentioned that these gardens are historic and represent a symbol for their cities. Hence, sense of attachment to these gardens was identified by 17.5% of respondents. Sense of attachment to a place result in a sense of belonging to towns and society and consequently enhance society’s health status. Silence of gardens, meeting people and familiarity option follow in decreasing frequency. Motives like garden’s silence and consideration of garden as meeting place reflect needs of experiencing solitude, as well as social relation and integration.

4.2 Functional Aspects of the Gardens Another aspect of gardens is how gardens are to be used by residents. To understand the functions of gardens in urban area, respondents were asked: “What is your experience and activity during visitation of garden?” The following alternative options were given: I come to visit this garden for recreation, for sitting alone, for wandering and walking, for family picnic, to be with others, to do exercise, to observe nature and to be part of nature. A frequency analysis of people’s activity in gardens revealed that the most important experience which is considered by respondents is recreation. 49.6% of respondents visit gardens for recreation (Fig. 2). This result denotes the psychological effects of nature which evoke calm and relaxation as well as stress reduction.

Subsequently, this confirms why 40% of respondents considered natural observation as second most important experience of garden. Also, 27.8% of respondents mentioned that visiting gardens is like being a part of nature. This result reflects again the importance of nature.

Family picnic (25.4%) and to be with others (22.2%) constitute another important aspects of garden’s function. These functions reveal the social aspects of gardens which encourage people to use urban green spaces as part of their daily life style and to be with others. Subsequently, increase social interaction and integration invoke trust and supportive behaviors. Other activities like sitting, exercising and walking follow in decreasing frequency and less considered by respondents.

4.3 The Emotional Dimension of Gardens’ Experience Another important research interest was to explore the emotional dimension of nature based *Corresponding author (R. ROSTAMI). H/P: +06-177187197 E-mail address: 2012. American Transactions on Engineering & raheleh.rostami@yahoo.com.

experiences, the benefits people perceive through natural contact and the relationship with their well-being. To explore emotional aspects of garden, respondents were asked to answer the following question: “What feelings do gardens evoke you?” and the following alternative options were given: safety, freedom, comfortable, happiness, calm and tranquility, memories remembrance, feeling healthier, feeling that you are closer to nature and feeling that you are different. Frequency analysis of the answers about the feelings experienced (Fig. 3) shows that “calm and tranquility” is the feeling most frequently cited by respondents, which accounts for 50% of the answers. The tranquil atmosphere of the garden inspires reflection, meditation, and a general feeling of harmony between one self and the surrounding. Also, it is assumed that feelings and emotions we perceive in natural environment are relevant part of our experiences in nature. So, integration of results of first important experience in gardens (recreation) and current finding verify the assumption. Memories remembrance is another emotional aspects which was considered by 42.8% of respondents.

Happiness is another feeling that gardens evoke for respondents, accounting almost 35% of the answers. Also, 33.7% of respondents mentioned feeling closer to nature. Therefore, it can be proven that there is a relationship between nature and positive feelings like happiness as well as comfortable (21.8%) and feeling healthier (19.4%). Feeling safe and freedom follow in decreasing frequency. Feeling “I am different in this garden” was less considered by respondents (2%).

4.4 Garden Visitation and Well­being For better understanding about the importance of natural experience for people’s well-being, respondents were asked to rank the importance of visiting gardens for emotional and physical disease like: depression, sadness, tiredness and sickness along a 1–5 points measurement scale (1, not important at all; 2, not important; 3, important; 4, very important; 5, essential). A frequency analysis showed that responses range from important to essential. Respondents believed that visiting gardens could mostly reduce depression (94%) as well as removing tiredness, accounting almost 90% of answers. Also, results show that sadness (81.6%) and physical sickness (76.3%) could be better during and after garden visitations. Overall, findings revealed nature effects on betterment of both emotional and physical disease, widely emotional ones.

At the end, to articulate aspects of historical Persian garden that could affect people’s presence, respondents were asked to rank the importance of the following features for people presence. Features include: garden’s organization, accessibility, familiarity, activity, naturalness, emotion and memory of respondents about gardens, garden’s representativeness and symbolisms.

Findings indicate that all features ranged as essential one with different frequency (See Table 1).

Garden’s organizations as well as representativeness are considered as most important features that could affect people presence for almost 37.9% of respondents. Symbolism identified as second *Corresponding author (R. ROSTAMI). H/P: +06-177187197 E-mail address: 2012. American Transactions on Engineering & raheleh.rostami@yahoo.com.

most important feature that affect 28% of people who visit these gardens. Most of respondents mentioned that people visit this garden because these gardens are historic. Accessibility and familiarity achieved a same value (27.2%) for people presence in gardens. Emotional and physical (activity) aspects of gardens follow in decreasing frequency, accounting around ¼ of the answers.

Respondent’s garden related memories identified as the last factor that could affect people presence in gardens (7.8%).

5. Discussions and Recommendations The information emerged from the survey indicates that historical Persian gardens fulfils important residents’ needs in urban context. Obtained results are according to previous researches regarding people’s need to experience nature (Kaplan and Kaplan, 1989). People visit gardens primarily because they want to relax. Recreation is as an important need fulfilled in Persian gardens (49.6%). Residents considered gardens as recreational area which is mentioned in Chiesura (2004) research and important factors to make the city livable, pleasant and attractive for its citizens and this is why ¼ of respondents carry out social activities like being with others and family picnic in these gardens. Social activities that happened in these gardens signify Coley et al (1997) results that nature can encourage the use of outdoor spaces and increase social integration and interaction among neighbors which lead to trust, mutual understanding, shared values and supportive behavior (Loures et al., 2007). Therefore from the social point of view, historical Persian gardens considered by residents as urban nature and daily outdoor recreation opportunities are the main factors that Eronene et al (1997) believed could enhance every day well-being.

Furthermore, findings show that the experience of nature in the city is a source of a large array of positive feelings to people. Calm and tranquility is the most important feeling that residents experience in historical Persian gardens. Besides, feeling happiness, comfortable, safety, freedom and even healthier were frequently mentioned by respondents. Results confirmed psychological health effects of nature on positive moods like pleasure which were indicated by Ulrich (1982) as well as reduction of negative effects like anger and anxiety (Rohde and Kendle, 1994) which evoke calmness and tranquility and provide restorative environments that can help strengthen the activities of the right hemisphere of the brain and restore harmony to functions on the brain as a whole (Furnas, 1979). In other words, people who have access to nearby natural settings were

290

found to be healthier overall than other individuals (Kaplan, 1989). And, all these emotional and psychological benefits contribute critically to the quality of human life, which in turn is a key component of sustainable development (Chiesura, 2004). This is why respondents ranged the importance of visiting gardens for emotional and physical disease as important and even as essential factors. Most of the respondents believed that during and after gardens’ visitation, depression and tiredness decreased and even sadness and physical disease could be lessened.

6. Conclusion In the context of this study, the role of historical Persian gardens as provider of social services and their importance for city sustainability has been addressed. Some results have been presented of a survey aimed at exploring the motives and perceptions of visitors of two well-known samples of historical Persian gardens. Some conclusive remarks can be made.

First of all, historical Persian gardens as natural urban area fulfill many social functions and psychological needs of citizens, which make these gardens a valuable municipal resource, and a key ingredient for city sustainability.

Secondly, attributes of the physical environment interact with various human characteristics, such as socio demographics and people’s perceptions of the environment could affect physical activities and this in turn influences health outcomes. So, links among environmental attributes, physical activity, body weight, and health can result in environmental compatibility and sense of attachment to a place which result on the quality of life and well-being.

Therefore, valuation of the various amenities, social and psychological services of urban areas should be integrated into project assessments’ procedure and be properly accounted for in policy decisions and urban planning strategies as well as user’s satisfactions, needs and their representation and participation in all aspects of urban life which are critical components in a sustainable city.

As designers of the built environment, architects have a tremendous opportunity to make a positive impact on the lives of the ‘bottom billion’. However, in order to be effective agents of change, these designers must understand and appreciate the concept of social responsibility in architecture, and learn to implement it in their own work. This study seeks to determine the current state of social responsibility training in architectural education by examining the curriculum requirements set by a number of national architectural education accrediting boards to determine whether they include training in the precepts of social responsibility in design. Because these curriculum requirements largely determine the topics and concepts that students will be exposed to in the course of their architectural education, improving this aspect of architectural education is an important step toward maximizing the profession’s contribution to the global effort to improve the lives of the ‘bottom billion’.

citizens who are intellectually mature, ecologically sensitive and socially responsible.’

-International Union of Architects (UIA, 2008) As designers of the built environment, architects have a tremendous opportunity to make a positive impact on the lives of the ‘bottom billion’. However, in order to be effective agents of change, these designers must understand and appreciate the concept of social responsibility in architecture, and learn to implement it in their own work. Including this subject in the standard architecture curriculum is an important step toward this goal. This study seeks to determine the current state of social responsibility training in architectural education.

Social responsibility in architecture may be defined in a number of ways. According to Paul Goldberger, an architecture critic for The New Yorker, ‘Social responsibility in architecture is, at least in part, a matter of believing, passionately and absolutely, in the potential of architecture to improve the quality of life.’ (Goldberger, 2002) This study will focus on four particular aspects of socially responsible architectural practice.

Sustainability: A considerable amount of attention has been focused recently on sustainable and environmentally responsible design. This is an important aspect of social responsibility in architecture, and while substantial progress has been made in this area, there is still significant room for improvement.

Responsibility to consider the needs of communities and the wider public: Architects have a responsibility to consider the needs of local communities and the wider public as project stakeholders and to reconcile the needs of these groups with those of a project’s client, owner and user groups. By understanding and embracing this responsibility, architects have the opportunity, within their professional roles, to become community advocates and agents of positive social change.

Ethics: Architects have a duty to understand the ethical implications of their design decisions in regard to social, political, environmental and cultural issues. Understanding these implications empowers architects to make responsible decisions.

Civic engagement through public service: Although architects have a unique and useful skill

296

Boonsap Witchayangkoon, and Paulo C.L. Segantine

set that enables them to serve as important contributors and leaders within society, civic engagement and public service in architecture is still significantly underdeveloped.

By

integrating civic engagement and public service into the practice of architecture, architects can apply their professional skills to the benefit of society.

While these issues certainly overlap in some respects, they also represent four distinct aspects of the socially responsible practice of architecture. These four aspects describe significant ways in which architects help to improve society’s quality of life through responsible practice and educating future architects in these aspects of social responsibility will significantly affect the profession’s ability to take up the moral challenge of addressing the needs of the ‘bottom billion’.

2. Approach The curriculum requirements set by architectural education accrediting boards around the world largely determine the topics and concepts that students will be exposed to in the course of their architectural education. This study examines the curriculum requirements set by a number of national architectural education accrediting boards to determine whether they include training in the precepts of social responsibility in design. The countries included in this study are those for which English-language accreditation criteria documentation is readily available.

3. Results For each country, the relevant accrediting authority and specific accreditation criteria are identified and examined below. The results are summarized in Table 10, at the end of the section.

3.1 Australia The accreditation of architectural academic programmes in Australia is jointly conducted by the Architects Accreditation Council of Australia (AACA) and the Royal Australian Institute of Architects (RAIA). (AACA and RAIA, 2006) According to the Australian Architecture Program Accreditation and Recognition Procedure, published jointly by these organizations, ‘Review of programs is undertaken with close reference to both the Architects Accreditation Council of Australia National Competency Standards in Architecture (NCSA 01) and The Royal Australian *Corresponding author (K.Kramer).

Institute of Architects Education Policy.

Extracts from these documents jointly form the

Accreditation and Recognition Criteria.’ (AACA and RAIA, 2006) The Accreditation and Recognition Criteria are organized into a list of numbered ‘Performance Criteria.’ Table 1 lists the Performance Criteria relevant to social responsibility in architecture.

Table 1: Australia: Social Responsibility Education Requirements for Accreditation, Extracted from the AACA National Competency Standards (AACA and RAIA, 2006).

Performance Criteria #

Text of Performance Criteria

06

The concept is informed by an understanding of the history of architectural thought and traditions of buildings and construction and by relevant current social and environmental concerns

11

The impact of the design concept upon the environment and the community is assessed and heeded

13

Respect for the natural environment and awareness of the issues of sustainability are demonstrated in the conceptual design

21

The interests of building users, the community and other relevant groups are investigated and reconciled with the project brief

22

Human, social, environmental and contextual issues are researched and addressed

54

Interests of building users, the community and other relevant groups are reconfirmed

86

Cultural factors relating to the project are researched and their influence and implications reported

87

Community participation processes are understood and recommendations made

88

Relevant environmental issues relating to the site and its location are identified and reported

145

An understanding of professional ethics as they apply to the practice of architecture is demonstrated and ethical practice observed.

An additional section of the Accreditation and Recognition Criteria includes Performance Criteria extracted from the Royal Australian Institute of Architects’ Education Policy. Table 2 lists the Performance Criteria relevant to social responsibility.

Together, the Performance Criteria outlined in Tables 1 and 2 constitute the required training for Australian architecture students in the precepts of social responsibility in design. These criteria require students to develop a significant awareness and understanding of the environmental impacts of their designs. They also require a high level of awareness and understanding of

298

Boonsap Witchayangkoon, and Paulo C.L. Segantine

community interests, needs and participation processes, encouraging students to consider the larger social impact of their designs and their responsibility as designers to acknowledge, assess and address these issues and impacts. The criteria glance on the topic of professional ethics, but stop short of encouraging students to understand and embrace the opportunity for civic engagement and public service in architecture.

3.2 Britain The accreditation requirements for British architectural education programmes are published as the Criteria for Validation by the Royal Institute of British Architects (RIBA). (RIBA, 2010) Table 3 lists the Criteria relevant to social responsibility.

The RIBA accreditation criteria require students to understand the impacts of their projects on the environment and communities as well as their duties and responsibilities as architects, not just to traditional project stakeholders but to the wider society. However, like the Australian criteria, the RIBA criteria stop short of encouraging students to understand and embrace the opportunity for civic engagement and public service in architecture. While an understanding of the ethical implications of design decisions is not required in the educational portion of the validation criteria, it is discussed in the RIBA Professional Criteria required to sit the Professional Practice Examination in Architecture.

3.3 Canada The Canadian Architectural Certification Board (CACB) assumes accreditation responsibility for University Schools of Architecture in Canada that offer a professional degree in architecture.

(CACB, 2011) The accreditation criteria are published as the CACB Conditions and Procedures for Accreditation. (CACB, 2005) For the purposes of accreditation, graduating students must demonstrate awareness, understanding, or ability in a number of ‘Performance Criteria.’ Table 4 lists the Performance Criteria relevant to social responsibility in architecture.

Table 4: Canada: Social Responsibility Education Requirements for Accreditation (CACB, 2005).

Environmental Conservation: Understanding of the basic principles of ecology and architects' responsibilities with respect to environmental and resource conservation in architecture and urban design

37

Ethics and Professional Judgment: Awareness of the ethical issues involved in the formation of professional judgments in architecture design and practice

When conducting accreditation reviews, the CACB also requires educational institutions to address the perspectives of each of its constituencies. This includes public members, addressed by the ‘Architecture Education and Society’ requirement:

300

Boonsap Witchayangkoon, and Paulo C.L. Segantine

‘The programme must demonstrate that it not only equips students with an informed understanding of social and environmental problems but that it also develops their capacity to help address these problems with sound architecture and urban design decisions. Given its particular mission, the APR [Architecture Program Report] may cover such issues as: how students gain an informed understanding of architecture as a social art, including the complex processes carried out by the multiple stakeholders who shape built environments; the emphasis given to generating the knowledge that can mitigate social and environmental problems; how students gain an understanding of the ethical implications of built environment decisions; and how a climate of civic engagement is nurtured, including a commitment to professional and public service.’ (CACB, 2005).

The CACB accreditation criteria require students to develop an understanding of environmental responsibility in design, as well as an awareness of the ethical issues involved in design and practice decisions. The Canadian criteria take a strong stance in demanding a focus on civic engagement opportunities and responsibilities for architects. Though implied, architects’ responsibility to consider the needs of the communities and the wider public is not specifically addressed.

3.4 Hong Kong Because of its size, Hong Kong takes a different approach to architectural education accreditation than most other countries. Rather than create a standard national set of criteria for accreditation, the Hong Kong Institute of Architects (HKIA), which is responsible for accrediting schools of architecture within Hong Kong, has simply made a list of schools whose architecture programs are accredited. Within Hong Kong, this includes the Master of Architecture program at The University of Hong Kong, and the Master of Architecture program at The Chinese University of Hong Kong. (HKIA, n.d.) The list also specifies overseas accreditation schemes which are recognised as equivalent by the HKIA: the U.S. National Architectural Accrediting Board (NAAB), the Commonwealth Association of Architects (CAA), the Architects Accreditation Council of Australia (AACA), and the People’s Republic of China National Board of Architectural Accreditation (NBAA).

A cursory examination of the two domestic masters programs accredited by the HKIA shows that the University of Hong Kong Master of Architecture programme does not prioritise the topic of social responsibility within their programme, though they do mention that ‘the design thesis is an opportunity for students to conduct research in areas that overlap staff research activities, including architecture’s relationship to the environment, its impact on community, and its potential to enrich culture’. (UHK, 2011) The Chinese University of Hong Kong’s Master of Architecture programme states that among the studios’ aims for its students in terms of professional competence is that ‘the framework and outcomes of the studios should reflect the following aspects: awareness of issues such as sustainability and economy’. However, this is the only mention of topics related to social responsibility in architecture. (CUHK, 2011; CUHK, 2010)

3.5 India In India, the Council of Architecture (COA) prescribes the standards of architectural education required for granting recognized qualifications. These standards are published as the Council of Architecture – Minimum Standards of Architectural Education, which supplement the 1983 COA Regulations. (COA, 2008) The Minimum Standards of Education were revised in 2008 to update the original 1983 document, which had no requirements for social responsibility education in architecture curricula. (COA, 2002) Within the Minimum Standards, the curriculum requirements are organized into ‘Subjects for Examination’ in two stages. Table 5 lists the Subjects for Examination relevant to social responsibility.

Table 5: India: Social Responsibility Education Requirements for Accreditation (COA, 2008).

302

Boonsap Witchayangkoon, and Paulo C.L. Segantine

The document also outlines a course of study for an Eco Architecture specialisation track at Stage 2. While it is heartening to see the COA criteria updated to include the subject of environmental responsibility in the standard architecture curriculum (this was lacking in the 1983 document), the criteria still do not mention civic engagement and public service in architecture, or the architect’s responsibility to consider the needs of communities and the wider public in addition to the traditional project stakeholders.

3.6 Korea The Korea Architectural Accrediting Board (KAAB) is responsible for accrediting architectural education programs within the Republic of Korea. The criteria for accreditation are published as the KAAB Conditions & Procedures for Professional Degree Programs in Architecture. (KAAB, 2005) The KAAB accreditation conditions require each architectural programme to demonstrate how it addresses a number of different perspectives. Table 6 lists those relevant to social responsibility in architecture.

Table 6: Korea: Social Responsibility Education Requirements for Accreditation (KAAB, 2005).

Perspective Registration (2.1.3)

Relevant conditions (for each condition, the following issues must be addressed) Delivering issues of responsibility for the society and ethics

Profession (2.1.4)

Issues in reconciling the conflicts between architects’ obligation to their clients, the society, and private enterprise.

Society (2.1.5)

The program must promote student understanding in various social, environmental challenges and foster skills dealing with these issues through proper architectural and urban design resolution

Society (2.1.5)

Importance of ethical implications of built environment determinations

Society (2.1.5)

Issues in promoting civic engagement through commitment to professional and public service

Additional KAAB accreditation requirements are listed in the Conditions & Procedures as ‘Student Performance Criteria’.

Text of Performance Criteria

(2.2.2) 14

Understanding of principles and theories of sustainability in designing and making of architecture and urban design decisions

(2.2.3) 17

Ability of comprehensive architectural design based on collective pieces of information on natural, environmental factors and limitations with consideration for sustainability

(2.2.5) 41

Understanding of ethical issues and responsibility as an architectural professional serving client in the context of society as a whole

The KAAB Conditions & Procedures document begins with the same excerpt from the UNESCO/UIA Charter for Architectural Education which is quoted at the beginning of this study: ‘Architectural education has two basic purposes: To produce competent, creative, critically minded and ethical professionals and designers/builders; to produce good world citizens who are intellectually mature, ecologically sensitive and socially responsible.’ (KAAB, 2005) This is a strong statement of commitment to social responsibility in architectural education but it is an appropriate one for the KAAB accreditation criteria, which take a serious stance on the issue of social responsibility in architectural education. The KAAB criteria require students to understand and address the issues of sustainability, ethical implications of design decisions, the architect’s responsibility to society as a whole, and civic engagement through professional and public service.

3.7 Malaysia Architectural education accreditation in Malaysia is managed by the Board of Architects Malaysia/Lembaga Arkitek Malaysia (LAM). The Malaysian criteria for accreditation, published in the Policy and Procedure for Accreditation of Architectural Programmes, are adopted from the 2003 British Criteria for Validation jointly approved by the Royal Institute of British Architects (RIBA) and the Architects Registration Board (ARB). (LAM, 2005 [Appendix A]; RIBA, 2003) The criteria specify that all graduates must ‘have knowledge and ability in architectural design including ecological balance,’ and that they ‘comprehend thoroughly the architects’ roles and responsibilities in society.’ (LAM, 2005)

The LAM accreditation requirements are further

clarified in Appendix A, organized as a list of learning outcomes. Table 8 lists the learning outcomes relevant to social responsibility.

3.8 New Zealand New Zealand uses the Australian National Competency Standards in Architecture under license. (McRae, 2011) Please refer to the ‘Australia’ section above for details of accreditation criteria.

3.9 Pakistan The Pakistan Council of Architects & Town Planners’ (PCATP) accreditation criteria, as published in the Accreditation Guide provide only very general, loose guidance in terms of expected educational outcomes.

at a Pakistani architecture firm and honorary treasurer of the Institute of Architects Pakistan, this is because: ‘After remaining in the doldrums for many years, the profession of architecture in Pakistan is showing signs of staging a revival. Unfortunately, decades of neglect and apathy have meant that there has been no significant growth in the quality or capacity of architectural education in Pakistan. The need to establish new institutions of architectural education and to improve the quality of the existing ones has put tremendous pressure on the regulating agencies... to develop and enforce criteria that are realistic and yet provide the impetus to improve the quality of architectural education in the county.’ (Belgaumi, 2008) The only element of the PCATP Accreditation Guide which touches on social responsibility is the following general guideline for External Interaction: ‘The institution should provide the environment, which fosters the personality of the students and provide them opportunities through co-curricular and extracurricular activities and student services. These opportunities are to enable the students to become responsible members of the society and should be readily accessible to the students.’ (PCATP, 2008)

3.10 Singapore Singapore’s approach to architectural education accreditation is similar to that taken by Hong Kong. Rather than create a full set of accreditation criteria, the Board of Architects (BOA) has identified two local programmes recognised by BOA for the purpose of registration. These programmes are the Bachelor of Architecture and Master of Architecture programmes at the National University of Singapore. The Board has also identified a list of overseas programmes in architecture with accredited courses recognised for the purposes of professional registration in Singapore. (BOA, 2010) A cursory review of the curriculums of the two accredited domestic programmes shows that in the Bachelor of Architecture programme, all students are required to take courses in Climatic Responsive Architecture and Strategies for Sustainable Architecture. The programme also offers students the choice pursuing a concurrent degree program in Design Technology and Sustainability. (NUS, 2008) The Master of Architecture Programme Information does not specify any particular curriculum requirements related to social responsibility in design. (NUS, n.d.)

3.11 South Africa South Africa’s architectural education programmes are validated by The South African Council for the Architectural Profession (SACAP), according to their Guidelines for the Validation of Courses in Architecture. Rather than provide a specific list of learning outcomes and criteria required for validation, this document references the general criteria for higher education quality assurance in South Africa (as outlined by the Higher Education Quality Committee (HEQC)) and provides guidelines based on international architectural accreditation standards: ‘In an international context criteria for validation should at least take account of the UIA/UNESCO Charter for Architectural Education, June 1996.

For credibility in the

international sphere within which architects from the Republic of South Africa operate (mainly Africa, the Middle East and Europe), broad conformity should also be sought with the RIBA Procedures, Criteria and Policies for the International Validation of Courses, Programs and Examinations in Architecture (February 2001) and the CAA Procedures and Criteria, Qualifications in Architecture Recommended for Recognition by CAA.’ (SACAP, 2007) The referenced validation criteria cover a range of approaches to social responsibility training in architectural education. RIBA validation criteria are examined in the ‘Britain’ section above.

Information about CAA and UIA criteria is presented in the ‘Future Directions – International Collaboration’ section below.

3.12 United States In the United States, the architectural education accreditation process is administered by the National Architectural Accrediting Board (NAAB). (NAAB, 2009) The 2009 NAAB Conditions for Accreditation require that: ‘students enrolled in the accredited degree program are prepared: to be active, engaged citizens; to be responsive to the needs of a changing world; to acquire the knowledge needed to address pressing environmental, social, and economic challenges through design, conservation and responsible professional practice; to understand the ethical implications of their decisions; to reconcile differences between the architect’s obligation to his/her client and the public; and to nurture a climate of civic engagement, including a commitment to professional and public service and leadership’ (NAAB, 2009) *Corresponding author (K.Kramer).

Performance Criteria #

Text of Performance Criteria

C

Leadership and Practice: Architects need to manage, advocate, and act legally, ethically and critically for the good of the client, society and the public. Student learning aspirations include: Knowing societal and professional responsibilities; Integrating community service into the practice of architecture

C.2

Human Behavior: Understanding of the relationship between human behavior, the natural environment and the design of the built environment.

C.3

Client Role in Architecture: Understanding of the responsibility of the architect to elicit, understand, and reconcile the needs of the client, owner, user groups, and the public and community domains

C.6

Leadership: Understanding of the techniques and skills architects use to work collaboratively in the building design and construction process and on environmental, social, and aesthetic issues in their communities

C.7

Legal Responsibilities: Understanding of the architect’s responsibility to the public and the client as determined by registration law, building codes and regulations, professional service contracts, zoning and subdivision ordinances, environmental regulation, and historic preservation and accessibility laws

C.8

Ethics and Professional Judgment: Understanding of the ethical issues involved in the formation of professional judgment regarding social, political and cultural issues in architectural design and practice

C.9

Community and Social Responsibility: Understanding of the architect’s responsibility to work in the public interest, to respect historic resources, and to improve the quality of life for local and global neighbors

In preparation for the 2009 update of the Conditions for Accreditation, NAAB convened an International/Global Task Group which created a prioritized list of issues to be considered in developing the 2009 Conditions. This task group identified ‘social responsibility’ as the number one priority. (NAAB, 2008)

This focus on the importance of introducing issues of social

responsibility in architectural education is apparent in the final Conditions document. While the 2004 NAAB Conditions already showed a strong commitment to issues of social responsibility in architectural education (NAAB, 2004), the 2009 document goes even further. The 2009 NAAB accreditation criteria require that students learn to understand and address the issues of environmental responsibility in design, architects’ responsibilities to communities and the wider

public, and the ethical implications of design decisions, and that accredited educational institutions nurture a climate of civic engagement, including a commitment to professional and public service and leadership.

4. Conclusion The examination of individual country accreditation criteria shows that most countries (8 of the 9 examined in the matrix above) have now embraced environmental responsibility as a required element of architectural education. This is an important issue for all of the world’s inhabitants, *Corresponding author (K.Kramer). Tel: +66-5394-2806. Fax: +66-5322-1448. E-mail address: kimberly.kramer@gmail.com.

but may be particularly important for the ‘bottom billions’, who are likely to be disproportionately affected by climate change, resource shortages, and other environmental problems. Adoption of strict standards of environmental responsibility in design is a significant way for the architecture profession to address the current and future challenges faced by the ‘bottom billion’, and it is heartening to see that this aspect of social responsibility is being almost universally acknowledged and embraced.

Requirements to teach architecture students about their responsibility to consider the needs of communities and the wider public in design decisions and the ethical implications of design decisions have not been as widely implemented (requirements for each of these aspects of socially responsible design have been adopted by only 5 of the 9 countries examined in the matrix above).

However, these aspects of social responsibility in design will also be very important as the profession moves forward to address the needs of the ‘bottom billion’. By understanding and embracing their responsibility to community and public stakeholders, architects become community advocates and agents of positive social change.

By understanding the ethical

implications of their decisions in regard to social, political, environmental and cultural issues, architects become empowered to make responsible, well-reasoned design and professional decisions. Both of these aspects of well-informed social responsibility will be critical as the profession moves forward to address the challenges faced by the ‘bottom billion’.

Requirements to teach students about the importance of civic engagement and public service in architectural practice are lagging even further behind, with adoption by only about 30% of the countries examined in the matrix above (3 of the 9). This is particularly disheartening as this is perhaps the most crucial aspect in the effort to get a new generation of architects involved in the global struggle to address the needs and challenges of the ‘bottom billion’.

Architectural

education gives its graduates a unique and useful skill set which will allow them to be leading contributors to this effort. However, in order to take full advantage of this tremendous potential, a culture of civic engagement and public service must be created within the academic institutions and the profession to educate, inspire and empower new generations of leaders.

5. Limitations It is important to note that this is an examination of the accreditation criteria of only those

countries for which English-language documentation is readily available. Ideally, it would be expanded to create a more comprehensive picture of the state of social responsibility training in architectural education.

It is also important to acknowledge that this is an examination of official accreditation criteria only, and not of the actual content of courses currently being offered within the accredited programs. Individual architecture schools and academic staff may emphasise or de-emphasise aspects of the accreditation criteria within their individual programs, and lack of inclusion of a certain aspect in official accreditation criteria does not necessarily imply that it is not being included as part of the curriculum. However, including these issues as a required part of the standard architecture programme is an important step to formalise the importance of social responsibility within the profession of architecture and to train an active, engaged, well-informed and socially responsible new generation of architects.

6. Future Directions – International Collaboration There is another, concurrent trend which will also have a significant effect on the pace and effectiveness of these changes in architectural education.

International collaboration in

architecture has been increasing (NAAB, 2008), and accreditation authorities have been responding by creating a number of international agreements, accords and organizations intended to promote the international mobility of architects and other design professionals.

6.1 Bilateral and multilateral mutual recognition agreements As explained above, the accreditation organizations of some countries such as Singapore and Hong Kong have established the equivalency of other national architectural education accreditation standards to their own in order to ease international mobility for architecture students and professionals. Other countries have also recognized the value of the inverse approach.

Korea’s accrediting board (KAAB) has noted that ‘it is also the interest of the KAAB for KAAB accredited degrees to hold comparable accrediting or validating status for accrediting / validating agencies abroad which promote corresponding values’, and South Africa’s SACAP notes that “for credibility in the international sphere within which architects from the Republic of South Africa operate,’ broad conformity should be sought with RIBA and CAA criteria.

Many countries have also gone beyond this unilateral approach to join bilateral or multilateral mutual recognition arrangements, which establish equivalency between national accreditation criteria for the purpose of professional registration. For example, in 2010 the Hong Kong Institute of Architects (HKIA) and the Architects Accreditation Council of Australia (AACA) signed an agreement establishing the mutual recognition of their accreditation systems of architectural programs. (HKIA, 2011) Many of the countries discussed in this study are also signatories of the multilateral Canberra Accord, which establishes recognition of substantial equivalency between accreditation systems in the architectural education of its signatories. (Canberra Accord, 2008) Such arrangements will likely become even more widespread as international collaboration in architecture increases.

As this process continues, it will be important to ensure that these

agreements serve to maintain or raise the requirements for training in social responsibility, rather than reducing them to the lowest common denominator.

6.2 Commonwealth Association of Arhitects (CAA) Since 1968, the CAA has published a List of academic architectural programmes that it considered to be of a sufficient standard to recommend recognition by national authorities. The List was intended to provide a means of recognition of courses in countries which did not have their own accreditation system. However, the CAA has identified a growing need for mutual recognition of qualifications between countries both within and outside the Commonwealth. The future formal purpose of the List is, therefore, twofold: a) to continue to provide the means of recommending recognition of a course to a national authority in a country which does not have its own validation procedure, and b) to provide a list of qualifications which can be recommended for recognition by all the constituent national authorities. (CAA, 2007) The CAA procedures and criteria are adapted from and compatible with the aims and objectives of architectural education set out in the Charter for Architectural Education created by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the International Union of Architects (UIA). (CAA, 2007)

General Considerations

Text of General Considerations

#0

That the educators must prepare architects to formulate new solutions for the present and the future as the new era will bring with it grave and complex challenges with respect to social and functional degradation of many human settlements. These challenges may include global urbanisation and the consequent depletion of existing environments, a severe shortage of housing, urban services and social infrastructure, and the increasing exclusion of architects from built environment projects.

#2

That it is in the public interest to ensure that architects are able to understand regional characteristics and to give practical expression to the needs, expectations and improvement to the quality of life of individuals, social groups, communities and human settlements

#7

That the vision of the future world, cultivated in architecture schools, should include the following goals : a decent quality of life for all the inhabitants of human settlements; a technological application which respects the social, cultural and aesthetic needs of people and is aware of the appropriate use of materials in architecture and their initial and future maintenance costs; an ecologically balanced and sustainable development of the built and natural environment including the rational utilisation of available resources; an architecture which is valued as the property and responsibility of everyone

6.3 UNESCO/UIA The UNESCO/UIA Charter for Architectural Education is the international benchmark for architectural education accreditation, referenced in most international accreditation agreements and accords, as well as some national accreditation criteria. As the standard for architectural education within the international community the Charter is an important medium for advocating social responsibility in architectural education around the world.

The 2005 UNESCO/UIA Charter for Architectural Education opens with some stirring language on the subject of social responsibility in architecture: ‘There is no doubt that the architect's capacity to solve problems, can greatly contribute to tasks such as community development, self-help programmes, educational facilities, etc., and thus make a significant contribution to the improvement of the quality of life of those who are not accepted as citizens in their full right and who cannot be counted among the architect's usual clients...Beyond all aesthetic, technical and financial aspects of the professional responsibilities, the major concerns, expressed by the Charter, are the social commitment of the profession, i.e. the awareness of the role and responsibility of the architect in his or her respective society, as well as the improvement of the quality of life through sustainable human settlements’. (UNESCO/UIA, 2005) The Charter also sets forth a number of ‘General Considerations’ and ‘Objectives of Architectural Education’ which take a similarly strong stance on the role of social responsibility in the architectural profession. Table 11 lists those most relevant to this discussion of social responsibility in architectural education.

The UNESCO/UIA Charter sets forth an inspiring vision of the role of architectural education and the architectural profession in addressing society’s challenges and needs. It provides a suitably ambitious set of criteria to serve as a benchmark for national and international architectural education accreditation criteria, and will hopefully serve to guide the profession toward a future in which all architectural education programmes produce graduates who are inspired and empowered to take an active and effective role in helping society to meet the challenges ahead.

Housing is one of the most important basic needs for the community. Many countries suffer from housing problems and take a number of procedures to solve it. This paper approaches one of the strategies used in many countries to provide housing which is Affordable Housing, presents the relations between affordable and sustainable housing and proposes the adaptable multifamily courtyard house as an approach to achieve a sustainable affordable housing. Method: A three items framework for adaptability is introduced, an example of adaptable courtyard multifamily housing is prepared and a comparison is made between the courtyard and the non-courtyard housing. Results: Support the argument of the possibility of investing the concept of multifamily courtyard house to achieve a sustainable adaptable housing with private courtyards for each dwelling which will lead, supposedly, to sustainable affordable housing. Conclusions: This study gives indicators for architects on designing a sustainable affordable multifamily housing.

1. Introduction Affordable Housing is one of the concepts that are used around the world to solve the housing problems and to ensure that housing is available to all of the people including the low-income people. The emergence of affordable housing belongs to the twentieth century and after the World War II and the main objective was to provide low-cost housing for low-income people.

Affordable housing can be defined as the house which provides safety, acceptability, within the applicable standards of housing and is designed, built to be available, accessible and convenient for all people including low-income people. In general it does not require the tenant or owner to spend more than 30% of their income on housing (Sidawi B. , 2008, p. 68), (Qeensland government - Department of housing, 2004, p. 2).

1.1 The Importance of Affordable Housing The importance of affordable housing is divided into several types of positive impacts, they are: economic impacts, educational impacts, healthy impacts and social impacts. Economic impacts include the costs and benefits can that may be measured by observing the production, business and the movement of funds that result from the housing projects. The social Impacts include the positive impacts of affordable housing on education, social life, health and other aspects that can't be easily measured in terms economic profit (Lubell, Crain, & Cohen, 2007, p. 2).

1.2 Strategies for Achieving Affordable Housing There are six strategies for achieving the affordable housing, they are: •

Using standards and determinants in designing and building housing units (Qeensland government - Department of housing, 2004, p. 3).

•

Increasing the density (Poulsen & Silverman, 2005, pp. 5-10).

•

Flexibility (Rao, 2010, pp. 36-40).

•

Standardization (Prince Abdullah Institute for Research, pp. 22-24).

•

Eco-Affordable housing – reducing running cost (Lindburg, Howe, Bowyer, & Fernholz, 2007, pp. 2-4).

2. The Multifamily Housing The emergence of multifamily housing belongs to the ancient time from the Roman till the multifamily housing projects in Europe after the Industrial Revolution and the World War II. The tendency towards the multifamily housing in Iraq during the last decades of twentieth century was for different reasons and the most important reasons of them are: •

The increasing needs for dwelling units.

•

The great increase in the urban residential land value as a result of the spread use of the single family house pattern in the urban area, which led to increase value of the residential land, especially near the centers of cities, services and transportations. This led to the trends of the efficient use of land to the optimum extent to provide housing for largest possible number of people and also to provide the best services to the highest residential density by using the multifamily housing.

•

Reduce the cost of services: Multifamily housing reduces the cost of services such as water supply, electricity, phone and sewage by reducing the length of these supplying networks if designed properly.

•

Multifamily housing reduces the continuous horizontal expansion of the city which result from single family housing pattern. The result of reducing the horizontal expansion of the city will lead to reduce cost of infrastructure, transportation and services.

•

Multifamily housing facilitates the possibility of building the largest number of dwelling units and in short time.

•

Multifamily housing has more economic efficiency compared to single family housing, which helps to provide adequate housing for largest number of people.

But there are some criticisms that were directed to the multifamily housing compared to single

family housing, and the most important of these criticisms is that the dwelling units don't have the ability to accommodate the changing requirements of occupants during the family lifecycle. In addition to this, there are other criticisms like the problem of providing the privacy and the pattern of possession of the dwelling units (Mohammed, 1989, pp. 36-40). *Corresponding author (Ali H.

3. The Concept of Adaptability The research presents adaptability as a strategy towards an affordable housing, and as an attempt to solve one of the most important multifamily housing problems. Previous studies defined adaptability as the building ability to be adapted to accommodate changing in requirements through simple changes. Adaptability indicates the extent to which the building can be adapted to the changes during the period of building’s life which is inevitable due to the changes in the requirements of families over time. The change of the building is inevitable due to the changing in the requirements of families over time or due to the different requirements of families from each other. Therefore, the most adaptable building is considered as the most efficient building and remain for a longer period because it can respond to the changes in requirements (Russel & Moffat, 2001. pp.2-4).

3.1 Adaptability Benefits This paper introduces adaptability due to its significance for housing and sustainability as for the following issues: •

Adaptability advantages for housing: Adaptability gives the house its ability to accommodate different requirements of different families which can achieve the concept of Universal Design; or to cope with changing requirements of the occupants during the family lifecycle.

As a result the family doesn't have to change its residence which associated with many negative impacts to the family. This paper proposes the adaptability in this point as a strategy to solve one of the most important problems in the multifamily housing.

•

The economic advantages of adaptability: There are several economic advantages from adaptability as it extends the service life of housing or extends its ability to achieve different functions. Adaptability provides the possibility of modifying the current house to achieve a different function or add another function to it according to the occupants' requirements (Hashemain, 2005, p. 9), (Gu, Xue, & Nee, 2009, pp. 1368-1369).

•

The environmental advantages of adaptability: Adaptability provides an adaptable house which provides many functions and have the ability to be adapted. As a result it has a longer life which participates in reducing the natural material consumption and the energy consumption. It improves the operational efficiency and contributes in the protection of the

322

Ali H. Al Jameel and Omar A. Al Hafith

environment by reducing the demolition and construction of building and as a result reduces the damage to the environment (Moshaver, 2009, pp. 4-6).

3.2 Adaptability Design Properties There are six design properties related to the adaptable housing, they are: 3.2.1 Structure Concentration and Structure Modularity Structure Concentration is a design variable which describes the structural system of buildings. It plays an important role in facilitating buildings adaptability as concentration means that the supporting points of the structure must be concentrated and reduced as much as possible to increase building adaptability.

The structural modularity indicates the extent of the similarity or repetition among the structural units in relation to its dimensions and sizes (Al-Nijaidi R. H., 1985, pp. 50-54).

3.2.2 Zoning the Areas of Special Provisions Zoning is one of design variables of the building plan, which describes the building's parts according to specific criteria. Zoning in previous studies related with two properties: activities' requirements in the different parts of the building and properties of building's elements itself.

For most studies, the idea of zoning in housing depends on the zoning of kitchens and bathrooms which must be clearly separated from other areas in the house because of the activities' characteristics that are carried out in them, as well as the properties of the services' requirements that are required in those zones (Lynch, 1956, p. 22).

3.2.3 Independency of Building's Elements The independence of the building's elements is one of the variables that is associated with the building's adaptability. The buildings are compound of a variety of interrelated elements and these elements are often of different materials and are therefore of different life period. These elements that are independent from each other can be changed or modified without affecting the other elements in the building (Al-Nijaidi, 1985, p. 54). *Corresponding author (Ali H.

3.2.4 Other Features Other features related with the housing adaptability are: overcapacity, additive forms and growth forms, which are proposed by Kevin Lynch (Lynch, 1956).

4. The Courtyard House This paper proposes the courtyard house as a strategy to achieve the sustainable house and aims to use the courtyard pattern in the adaptable multifamily housing to offer a sustainable affordable housing.

4.1 Sustainability in the Courtyard House Pattern The severe environmental condition in the hot arid regions has clear effects in the design of houses which is associated to the use of courtyard in house design. The courtyard provides the required optimum environmental conditions and at the same time provides the required privacy in Islamic and Arabic cities.

The courtyard house provides the required exposure to the sun which must be exactly determined. The courtyard house provides also the required natural ventilation between the inside and outside. It is associated with the required humidity which provide more comfort for the occupants.

Ali H. Al Jameel and Omar A. Al Hafith

The courtyard house is also associated with the use of wind tower which take the cold air from the outside to the inside. In 1989, Givoni made an experiment to prove the efficiency of courtyard and wind tower to provide comfort conditions in the house depending on a natural tactics. Givoni designed a wind-tower in a courtyard house in Saudi Arabia (Figure.1), and he proved that it is possible to cool down the house by 9.9 Co between the outside and the internal rooms, and 6.7 Co between the outside in the internal courtyard. He also discovered that it is possible to improve the courtyard and wind tower efficiency when he used a sprinkling water and a fan in the wind tower.

He found that the difference between the outside and the internal rooms could reach to 11.1 Co cooler and between the outside and the internal courtyard could reach to 13.5 Co cooler (Edwards, Sibley, Hakmi, & Land, 2005, pp. 221-241) All of these make the courtyard house consumes less energy and natural resources; and fewer producers of bad effects on the environment and achieve one of the most important points in Sustainable Architecture.

5. Adaptable Multifamily Courtyard House This paper aims to show the possibility of making adaptable multifamily courtyard houses. An example of adaptable multifamily housing has been proposed and a comparison is carried out with a normal adaptable multifamily housing according to their adaptability to prove the possibility of making adaptable multifamily courtyard house.

5.1 Two Types of Adaptable Housing This paper introduces two types of adaptable multifamily housing. One of them adopts the concept of courtyard while the other does not.

5.1.1 Non­Courtyard Housing The example in (Figure 2) shows a model of multifamily non-courtyard housing. The building is a residential building in the (NIS) employing the characteristics of adaptable design.

The building was designed to ensure the provision of many possibilities in the organization of residential units within the building as the design provides adaptability in the apartments to expand, *Corresponding author (Ali H. Al Jameel). E-mail address: ahsaljameel@yahoo.com.

minimize or modify the apartment according to the family's requirements (Jovanović, 2007, pp.

33-47).

Figure 2: The plans and drawings of the non–courtyard multifamily housing.

5.1.2 Courtyard Housing The second example is a multifamily housing building adopts the concept of courtyard. The building provides private court for each apartment in the building. The design provides many possibilities to make changes in the dwelling units' arrangement within the building. It also provides the possibilities to expand, minimize or modify the apartments of the building according to the family's requirement (Figure 3). (Al Hafith, 2010).

6. Measurement of Properties Related Adaptable Design This paper measures three of the design characteristics that affect the building adaptability which represent the dependent variable.

6.1 Structure Modularity Structure Modularity can be measured by dividing the number of types of compound structure units to the total number of compound structure units of the building. The minimum amount of the ratio means that the building is more adaptable (compound unit consist of columns, beams and ground slab which based on them).

E1 x1/y1

Where (E1) is the ratio of types of compound structure units to the total number of compound units, (x1 ) refers to the number of types of compound structure units and (y1) refers to the total number of compound structure units.

The smallest amount of this ratio means that the building has more structure modularity and as a result it has more adaptability (Al-Nijaidi R. H., 1985, pp. 82-83).

6.2 Structure Concentration Two indicators are adopted to measure the structure concentration which affects the building's adaptability.

Indicator 1, measures the structure concentration by dividing the number of supporting units to the total area of the building, the minimum ratio means that the building is more adaptable.

Indicator 2, measures the structure concentration by dividing the area of supporting units to the total area of the building, the minimum ratio means that the building is more adaptable

Where (E2) is the ratio of number of supporting units to the total area of the building, (E3) is the ratio of area of supporting units to the total area of the building, (x1) refers to the number of supporting units in the structure, (x2) refers to the area of supporting units in the structure and (y1) refers to the area of the building. The smallest amount of these ratios means that the building has more structure modularity and as a result it has more adaptability (Al-Nijaidi R. H., 1985, pp.

83-85).

6.3 Zoning Areas of Special Provision Proximity is used to measure the zoning of areas of special provision; proximity refers to the distance between any two rooms and can determine the extent of areas of special provision. The zoning is determined by the ratio of the distance between the rooms of special provision and all other rooms in the building by using the formulas below:

Xx x1 x2 x3 xi /i

4 ,

Yy y1 y2 y3 yi /i2

5 ,

R Xx/Yy

6 ,

Where (R) is the ratio of the distance between the rooms of special provision and all other rooms in the building, (x) is the average distance between each special room and all other special rooms in the building, (y) is the average distance between each room and all the other rooms in the building, (Xx) is the average of the average distances between each special room and all other special rooms in the building, (Yy) is the average of the average distances between each room and all the other rooms in the building, (i) is the number of the rooms of special provision and (i2) is the number of common rooms. The smallest amount of this (R) ratio means that the building has more structure modularity and as a result it has more adaptability (Al-Nijaidi R. H., 1985, pp. 89-92).

7. Comparing the Two Types A comparison between the two cases is made to support the argument of the possibility of making adaptable courtyard multifamily housing implying a single private courtyard for each dwelling unit in the building. The research measures the examples' adaptability by measuring three variables of adaptability. They are structure concentration, structure modularity and zoning of

special provision. The first two variables will be calculated for the whole building, while the third variable will be calculated for the apartment within the building.

7.2 Structure Modularity Structure concentration and modularity have been clarified in (Figure 4) for the two examples.

Modularity has been measured depending on equation (3) and the results are as the following: The courtyard house: 4 \ 24 = 0166 The non-courtyard housing: 6 \ 20 = 0.3 It can be seen that the courtyard house has the largest and the biggest concentration in the building and the biggest amount of modularity, which means that the case of courtyard housing is more adaptable than the other.

7.3 Zoning Areas of Special Provision Zoning has been measured using equations (4), (5) and (6). Figure 5 and Table 2 clarify the measurement of zoning in the two examples.

It can be seen that the zoning of areas of special provisions in the courtyard housing is greater than the one in the non-courtyard housing. This means that the courtyard building is more adaptable.

8. Conclusions & Recommendations 8.1 Conclusions •

Adaptability is a significant strategy for achieving affordable housing in terms of reducing the cost of housing in the long and short terms as it offers the possibility of constructing small units compatible with the requirements of the beginning families to grow and evolve with changing requirements without the stress of moving into new houses.

•

This paper supports the argument that (Adaptability) represents a convenient solution for one of the most important problem in the multifamily housing which relates with ability of dwelling units to accommodate with changing requirement of the occupants.

•

Adaptability plays an important role for the issue of sustainability in terms of reducing the consumption of natural resources and wastes of buildings and destruction.

•

Courtyard house with wind tower play an important role for the issue of sustainability in terms of reducing the consumption of energy, operating costs as well as the courtyard association in satisfying the social requirement in terms of providing the required privacy.

adaptable multifamily housing to achieve a sustainable affordable multifamily housing.

8.2 Recommendations •

Courtyard housing must be adopted in the hot arid area to achieve sustainable affordable housing.

•

Adaptability must be adopted in a multifamily housing to achieve sustainable affordable housing and to solve one of the multifamily housing problems.

•

To achieve adaptability, the designer has to use the Beams & Column Structural System with minimum supporting units and minimum structural area which will ensure the provision of the biggest possible free area for occupants to arrange or modify it according to their requirements.

•

To achieve adaptability, the designer has to design the building plan and structural system in a way that makes the whole building composes of several similar units. This will facilitate the modification, addition or subtraction in the dwelling units and in its building as a whole.

•

To achieve adaptability, the designer has to design the building and dwelling units plan putting the areas of special provision in a dependent zone, leaving the biggest possible free area in the dwelling units for occupants to arrange or modifying it according to their requirements.

•

The paper recommends studying design characteristics that are related with adaptability and clarifying the exact influence and relative importance of each of them for adaptability.

In the face of rapid economic development, people increasing needs and changing lifestyles, most historic centers in the Arab world have experienced problems in making the necessary adaptation to the present needs and change. In the Casbah of Algiers, while the number of houses was reducing due to dereliction the density was rising and reached 4,000 persons/ha, making it one of the highest densities in the world. In addition, lack of services and poor sanitation has accelerated the dilapidation and decline of the Casbah, to become an urban slum in the heart of the capital Algiers. The Casbah of Algiers presents an urgent case for urban conservation. UNESCO inscribed it on the World Heritage list in December 1992, but since then there has been continuous disrepair, from 1,200 historic buildings in 1962 only 400 have remained and the number is still decreasing. The cultural heritage of the Casbah should be recognized as a valuable resource for future development. This paper attempts to propose an urgent integrated urban conservation action to rescue the Casbah from vanishing to become a sustainable living heritage.

1. Introduction In the face of rapid economic development, population growth, people increasing needs and changing lifestyles, most historic urban areas in the Arab world have experienced problems in making the necessary adjustment and adaptation to the present needs and change. Today, these historic centres are not only a shelter for migrants but are also very productive. Located in a central position in the growing urban areas, they have to function as a city centre. Consequently, they keep the medina alive and they participate in the economic growth of the city. From the view of experts, people choose travel destinations where they can learn about traditional and distinct cultures in their historic context. In view of the importance of ‘heritage’ to the development of tourism, hotels and catering and the scant attention given to heritage raise the issue of heritage tourism.

There is a growing belief that most of the historic city centers in the Arab world are facing multiple pressures to sustain their characteristics and values. Competing demands for land use, the introduction of new economic activities, and the marketing of heritage resources places an important burden on the local heritage players. These are striving to find appropriate ways to manage these historic assets, in order to save them from the threats of mass tourism and over-consumption. The balance that must be maintained is between visitor access and conservation needs.

During recent years new policy mechanisms have emerged to reconcile the conflicting demands of conservation and development by applying sustainable development policies in historic cities. These issues will be explored through the case study of the Casbah of Algiers in Algeria, a World Heritage Site at risk. Throughout this case study, this paper will conclude with a discussion of the more general implications of the sustainability/historic city centre debate.

2. Urban Conservation and Sustainability What is sustainable development? The 1987 report "Our Common Future" from the United Nations World Commission on Environment and Development (WCED) set forth the most widely used definition of the concept: “Sustainable development is development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs”. The Brundland Commission lists food, water, clothes, shelter, work, energy and hygiene as examples of what is termed ‘basic needs’ (Brundland Commission, 1987: 8 & 44).

Sustainable development can be seen today as a powerful motivation for urban conservation planning. Basically, it consists of a process of urban development based on the constant reuse of existing built resources, associated with a low input of energy for adaptation to new requirements conceived in society. It is also viewed as a process founded in the local culture, in an equitable distribution of urban services, the use of democratic principles of management, the maintenance and regeneration of traditional social values and practices.

From the perspective of sustainability, cultural heritage is understood as a non-renewable resource. It includes some of the most important intangible values of society (identity, memory, self-consciousness and history). Moreover, it is an asset capable of attributing value to new things through the creation of new processes based on established values. As a man-made product, a city is an artifact composed of various historically recognizable parts.

In a progressively competitive global market where spatial and temporal barriers are disappearing, the identity of a place – its character, history, buildings, culture and distinctivenessbecomes crucial (Boussaa, 2003). With a rapidly globalizing flow of resources, information technologies and know-how, the distinctiveness of a specific historic city assumes greater significance in attracting both financial and human forms of investment (Urry, 1995). This local-global dimension of exchange contributes to explain why the local heritage players seek a competitive advantage over similarly historic areas. Cities that demonstrate through promotion and marketing their historical richness are more appealing to those with capital seeking attractive locations, especially for visitors and tourists (Strange, 1997).

In heritage cities, history and heritage have become the dynamic assets that combine the local and the global. They establish the local specificity and distinctiveness so attractive to a globalizing tourist market. Furthermore, they structure the localized patterns, which are brought about by a combination of national and international money exchange. However, the consumption produced by the com-modification, interpretation and replication of a place’s history is not infinite. Rather, the historical relics of a city are liable to deteriorate when ‘over-consumed’ by increasing visitors and the city is pressured for new forms of development. *Corresponding author (D.Boussaa).

In many historic cities, a ‘local fatigue’ results when consuming local infrastructure, historic buildings versus a demand on land, growing social conflict between visitors and local inhabitants, as well as the environmental impact of tourism (Glasson & al, 1995). These tensions between the demands for development and conservation in historic cities have raised the issue of introducing sustainable development policies to counter the consequences of diminishing resources. Such an interpretation implies that there are limits to growth that must not be breached within a historic city as stated by Jacobs: “A limit to the amount of development which an area can take over time, determined by its environmental characteristics…[and]…that if development exceeds a particular level, the loss of or damage to these features [environmental characteristics] will be unsustainable or otherwise unacceptable, and should therefore not be permitted" (Jacobs, 1997: 6).

Historic cities have unique characteristics that guarantee their special conservation and sustainability. On one hand this implies that development in these historic cores should be limited, while on the other hand the issue of maintaining local economic vitality cannot be undermined.

Most of heritage players recognize that such places cannot reproduce themselves without some kind of intervention. These are meant to regulate and manage the physical and social fabric upon whom their local identity and economic success is predicated. In this way it is possible for a range of sustainable economic development approaches to co-exist within and between cities-those which may be growth limiting, growth enhancing, or an integration of both (Strange, 1999).

3. The Casbah of Algiers and Rapid Change Algiers has an area of 276 Km2 and a population of more than 3 million. The Casbah is situated on the coast to the north of the city. The complex labyrinths and a fortress from the 1500s remain as reminders of the past. The Casbah of Algiers (Figure 1) was founded in the 6th Century BC, and was constructed on a steep slope (118m.high), facing the harbour bay and the Mediterranean Sea. Its historical function was military and trade.

The Casbah of Algiers, a landmark of Algerian history in the heart of the capital city, presents an urgent case for urban conservation. UNESCO inscribed the Casbah of Algiers on the World Heritage list in 1992, but since then there has been continuous degradation. The population grew from 60,000 in 1969 to reach 70,000 in 1980, a double of what was in 1830. While the number of houses is reducing, the density is rising and reached 4,000 persons/ha in several districts, making it one of the highest densities in the world (Lesbet, 1987: 67).

Since independence, the original urban and traditional families have been progressively abandoning the Casbah and moved to modern villas and flats on the outskirts of the city. In 1962 there were about 1,200 traditional buildings in the Casbah, going back to the Ottoman era. Thirty years later, 250 traditional dwellings disappeared, giving an average loss of 20% of the initial number (Ministry of Culture and Communication, 1992: 27). The old houses have been rented to rural families migrating to the city. In the meantime the number of houses rapidly diminished due to deterioration and collapse. About 50 dwellings collapsed between 1975 and 1979 (Lesbet, 1985: 101).

In addition to the problem of dwellings collapse a large number of significant public facilities disappeared (Figure 2). Mosques and Zaouias (Coranic schools) have been subject to major loss, from 130 mosques and 18 Zaouias only 10 mosques and 2 zaouias survived, while only six hamams (public baths) remained from an original number of about one hundred. With the absence of any legislation and planning control to protect the Casbah, each time a house was demolished, it was replaced by an apartment block, which destroyed the historical townscape and obstructed views to the sea for the adjacent neighbours. *Corresponding author (D.Boussaa).

Figure 2: Showing the state of deterioration and dereliction making the Casbah an urban slum in the heart of the capital.

This cycle of deterioration and disrepair resulted in a situation in which the Casbah is perceived as an urban slum in the heart of the capital. It is seen as the home of low income and desperate families, a place of misery, overcrowding, violence and insecurity.

The present

population of the Casbah is 70,000 concentrated on 37 hectares (13 hectares representing the vacant land of the buildings collapsed). With an average 12 persons/per room, the traditional house originally designed for one family, now is sheltering around 6 families, an average of one family per/room. This situation has meant that even the common spaces, such as the central courtyard, the surrounding corridor and kitchen have been occupied and subdivided. Only 400 dwellings have survived. This number is due to decrease dramatically if no urgent rescue and salvation action is undertaken. Sustainable development and heritage tourism can form the main catalyst for the revitalization of the Casbah, both socially and economically. After long years of neglect and marginalization this strategy might help the Casbah regain its legendary place within the new growing metropolis of Algiers.

4. The Need for a Sustainable Development Approach Since 1962, the state has been trying through a multitude of conservation plans to conserve the Casbah, but all these plans were not implemented. Apart from restoring a number of monuments and dwellings, no comprehensive action was undertaken to cover the whole urban center. The dilemma of conserving the Casbah is too complicated; it presents one of the rare dichotomies between providing a decent shelter to the low income inhabitants and the need for urgent rehabilitation. Now that the Casbah is on the “world heritage list”, it should not be left to become

Djamel Boussaa

a â&#x20AC;&#x153;world heritage at riskâ&#x20AC;?.

As a starting point, a number of steps and measures should be taken to make the conservation of the Casbah a reality. The first step would be a comprehensive survey and inventory of the remaining buildings. Secondly, selecting of what should be conserved based on the conditions of each building and the values it reveals. Thirdly, a typological analysis of houses and other monuments should be identified and surveyed to be used as a guide for future design, especially in the case of infill and reconstruction projects. Finally, a participatory approach should be promoted to involve the local inhabitants in the rehabilitation process.

In addition to housing, heritage tourism can be a major way of intervention in the Casbah. The historical separation between the private part (residential) and the public part (commercial), in the Casbah should be sustained. There is a need to rehabilitate the higher Casbah for housing, while the lower part for tourism and commercial activities. In this context, the infill projects and reconstruction work should be planned to provide adequate shelter for the local inhabitants, while promoting tourism in the Lower Casbah. Heritage tourism can be a catalyst to sustaining the heritage center by introducing the hard currency. In this way, revenues generated from tourism could be used to finance the restoration and upgrading of the remaining dwellings in the Higher Casbah while regenerating life in the historic center.

The heritage players should bear in mind, that the Casbah is meaningful only if it is inhabited; it is the reflection of the past and the people who live and work there. As such, the Casbah must work in a way to upgrade the living conditions of its inhabitants which form the basis for any sustainable development strategy. While tourism can be promoted, consuming and marketing heritage resources should be kept to the level of not threatening the identity and distinctiveness of the Casbah.

In order to change the image of the urban slum, there is an urgent need to inject a new heart in the Casbah. It is important to stress that the residents of the Casbah have the right to live in a decent shelter, work and be proud of their historical setting. Therefore, the first action to be taken is to stop the drift of rural migrants to the Casbah. The second one should aim to reduce the occupancy of *Corresponding author (D.Boussaa).

houses by half from 6 to 3 families per house. This can be achieved by reconstructing the demolished houses in the vacant lands.

The right to work is another imperative of sustainable development; therefore as a third measure, there is a need to encourage the revival of the vanishing traditional crafts in the Casbah.

These will give a new breath of life to the Casbah, and will contribute to its economic and social sustainability (Figure 3). This approach will enable the creation of jobs for a large number of people unemployed. Once the main heritage resources are conserved, and the cultural and economic activities enhanced, it is possible to present these heritage assets to visitors and tourists.

The situation of the Casbah along other historic city centers in the Arab World is particularly alarming. The historic town is both the content and container of urban heritage. While heritage tourism is an important and desired activity for both visitors and hosts, the challenge to cultural resource managers is to minimize the amount of damage that visitors may cause to sites. The following points emerge as principles for an appropriate visitor management to the Casbah and other historic areas: â&#x20AC;˘

any tourist potential; •

It should be a fundamental principle of any tourist development plan that both conservation, in its widest sense, and tourism benefit from it;

•

The best long-term interests of people living and working in any host community should be the primary determining factor in selecting options for tourist development;

•

Educational programs should insist and invite tourists to respect and understand the local way of life, culture, history and religion;

•

The design of buildings, sites and transport systems should minimize the potentially harmful visual effects of tourism;

•

Pollution controls should be built into all forms of infrastructure;

•

Adequate management should define the level of acceptable tourism development and provide controls to maintain that level;

•

Enable the local population to participate during the selection process and development phases;

•

Develop adequate protective measures to keep visitors away from sensitive parts of the historic centre.

These principles are crucial for tourism development in historic urban centers. While in most

urban cores lacking enough funds to save their cultural heritage, tourism can provide the necessary hard currency to finance the restoration work. In this way, conservation and rehabilitation can be pursued to cover the entire historic urban center. In short, these principles aim to prevent heritage tourism from becoming blight but blessing for all, the host community and tourists.

The concept of sustainability in historic city centers is still under scrutiny. Further study and analysis is required for the application of sustainable development approaches in the Arab World.

So far, no precise indicators have been developed in relation to the built heritage. Nevertheless, some general guidelines can be proposed that might be relevant to achieve sustainable conservation and development of the Casbah and other historic city centers in the Arab world: •

Respect community life, with specific emphasis on the local values and traditions;

•

Improve the quality of life;

•

Maintain identity, diversity and vitality;

•

Minimize the loss of non-renewable heritage assets;

•

Involve different actors from both the public and private sectors in the conservation process;

•

Empower community action and responsibility through participation;

•

Provide an appropriate strategy for integrating conservation and development;

•

Define the capacity by which change can be allowed in historic centers;

•

Issues such as gentrification and authenticity should be taken into consideration when applying a sustainable development approach in the historic city.

The above actions cannot be implemented without an active participation of the local

inhabitants. Therefore, there is need to encourage community participation and involvement of the heritage associations and the larger community. This should be done in collaboration with the local authorities that have the duty to manage the remaining 400 buildings. Heritage management is essential for regulating and maintaining an appropriate level of marketing and reusing the heritage assets.

Algiers is the main coordinator body between the other heritage players. In order to implement the recent Casbah Safeguard Plan, this coordinating body should be in close contact with the Algiers Municipality as well as the ministries of Culture and Housing. In addition, this unit should be open to the Casbah inhabitants and the general public, the different associations, as well as the training and research centers. Therefore, it should be located in the heart of the Casbah.

5. The Casbah: A Living Heritage The citadel was the first restoration project undertaken in the Casbah. This heritage complex encompasses the Dey Castle, castles of the Beys, two mosques, gardens and annexes lying over an area of 11,000 m2. Restoration work started in the late sixties and is still underway. The restoration of the historical monument (Bastion 23) was the second major operation; it was launched in July 1988, and it is now open for public as a museum (Figure 4). This historic monument is an ensemble composed of three palaces, nine houses and defense batteries. It represents the last testimony of the destroyed marine district and lies on an area of 4,000 square meters. These two landmarks, forming two main boundaries in the higher and lower parts of the Casbah are being re-used as museums and cultural centers, and have become two main attractions for both the local and foreign visitors.

In addition to these two major projects, around 37 dwellings were restored. A number of new public facilities were introduced in the Casbah, namely 3 libraries, 2 kindergartens, and 16 open-air *Corresponding author (D.Boussaa). Tel: +974-44034346 / Fax +974-44034341.

areas. These new infill projects are meant to revitalize and enhance the living environment of the local inhabitants as a basis for sustainable development. Furthermore, two main streets (Figure 5) in the Casbah (Rue Rabah Riab, and Sidi Driss Hamidouche) have been rehabilitated along with the reconstruction of five public fountains (Ministry of Culture and Communication, 1992). While these projects are intended to upgrade the living conditions they can also form a major catalyst for a sustainable living heritage.

Despite the problems of insecurity encountered during the last ten years, the Ministry of Culture and Communication succeeded during the period 1994-2000 to implement 13 restoration projects with the assistance of Italian experts. These are mainly monuments: 10 mosques, one castle (Dar Aziza) and the Bastion 23 complex. In addition, few refurbishment works were undertaken on the main buildings in the Basse Casbah, in an effort to recreate the historical link between the Casbah and the sea which is its "Raison d'ĂŞtre" (Zadem, 2002: 147). This link has been revived to become a main hub for tourists with its shopping and a wide range of restaurants.

It can be noticed that there has never been any comprehensive intervention in the Casbah.

Most of the work was piecemeal without any considerable effect, and not worthy of the World Heritage status of the Casbah. An insignificant number of buildings have been restored and rehabilitated since 1962; most of them are monuments, while dwellings are still struggling to survive due to their advanced state of dilapidation and decay. This process of work cannot rescue

the Casbah nor can it sustain it for the present and future generations. While neglect is due mainly to a lack of political will, lack of funds is another obstacle. Therefore, heritage tourism can play a major role in reviving the Casbah socially and economically. In addition it can generate the necessary funds to pursue the conservation endeavor for the entire world heritage center.

In the light of the problems facing historic cities in the Arab World, further study and research is needed. The idea that effective action to promote conservation and management of historic centers requires the implementation of a common strategy which can be based on the following assumptions: •

Historic centers are meaningful only if inhabited; they are the reflection of the past and the people who live and work there;

•

Consuming and marketing heritage resources should be kept to the level of not threatening the identity and distinctiveness of the historic cities;

•

Historic centers must work in a way to upgrade the living conditions of the local inhabitants, and should therefore contribute to ensure their basic needs.

The alarming situation of the Casbah demonstrates that the fundamental problem in urban conservation is the establishment of urban management policies and community development actions. These measures can play a major role in sustaining the conservation and regeneration of this historic city. Obviously this can be achieved by the close cooperation of the private and public sectors, as well as the NGO’s associations, for the safeguard of this nonrenewable cultural heritage.

The trend should be to reverse the situation from a world heritage at risk to a lively and bustling urban centre with a new beating heart.

In order for the built heritage to be incorporated in the aim of establishing a sustainable society, the ‘static’ goal to protect must be married to the managed ‘processes of change. The capacity of the historic center to accept change will depend on relative values that are placed on heritage assets and the priorities of each society (Pickard, 2001: 290).

6. Conclusion The paradox of conserving the Casbah is too complex; it presents one of the rare dichotomies between providing a decent shelter to the low income inhabitants and the need for urgent rehabilitation. Now that the Casbah is still on the “World Heritage List”, it should not be left to become a “World Heritage at Risk”.

This paper attempted to propose an appropriate conservation management strategy for the Casbah of Algiers. The Functional Unit in Charge of the Rehabilitation, Safeguard and Management of the Casbah of Algiers is the main coordinator body between the other heritage players. In order to implement the recent Casbah Safeguard Plan, this coordinating body should be in close contact with the Algiers Municipality as well as the ministries of Culture and Housing. In addition, this unit should be open to the Casbah inhabitants and the larger community.

As a matter of urgency, a number of steps and measures should be taken to make the revival of the Casbah a reality: 1. Undertaking a comprehensive survey and inventory of the remaining buildings; 2. Selecting of what should be conserved; 3. Identify and survey the rescued structures for use as a guide for future design, in the case of infill and reconstruction projects.

4. Promote a participatory approach to involve the local inhabitants in the rehabilitation process.

In order to make the Casbah a living heritage, there is a need to rehabilitate the higher Casbah for housing, while the lower part for tourism and commercial activities. In this context, the infill projects and reconstruction work should be planned to provide adequate shelter for the local inhabitants, while promoting tourism in the Lower Casbah.

The heritage players should bear in mind, that the Casbah is meaningful only if it is inhabited; it is the reflection of the past and the people who live and work there. The right to work is another imperative of sustainable development; therefore, there is a need to encourage the revival of the vanishing traditional crafts in the Casbah. These will give a new breath of life to the Casbah, and will contribute to its economic and social sustainability.

Conserving the Casbah is not a matter of restoring few houses but a question of maintaining the vitality of the entire historic centre. The problem of the Casbah is a shared one; there is a need to save it so it can act as a model for other historic centres in Algeria, like Constantine, Temacine, Ghardaia, Dellys and so on. The Casbah is an example which can provide hope or defeat for the future of historic centres in the Arab World as a whole. Therefore, the proposed strategy should be implemented urgently before witnessing more losses in the Casbah cultural heritage.
