Behind the Scenes: Successful Window & Door Installations

EDITOR’S NOTE

Renu Rajaram

renu@wfm.co.in

The Indian façade & fenestration industry is placing its bet on domestic demand rising in the years to come as it tries to counter the slump in the construction industry that haunted the sector in 2015. Amidst subdued demand and the spectre of China flooding global markets with cheaper products, the going was tough in the past few years, but experts are predicting smoother sailing in the coming years, with the government’s focus on ‘Smart Cities’ and many other massive projects including the forecast of 20 million new houses being built in the next 10 years. Experts are hopeful that the industry will take off and translate into sustained demand in the next couple of years. Developers, with unsold sets to the tune of 30 percent, may also see light at the end of the tunnel and progress construction work. The main story of this edition provides an insight into the operating environment of the uPVC windows and doors industry in India in this milieu.

This edition presents many other interesting articles. We discuss numerous vital, virtually unknown steps applicable to all frame materials, before a window or door frame can be actually manufactured and installed. We also look into various components of rear ventilated façades and how they help in reducing the energy consumption of a building. Improving indoor air quality by demand controlled ventilation in this era of pollution is a new concept. The importance of onsite test methods of the system after assembly and installation have been discussed. Many of our airport designs showcase best of technologies.

We have presented a few case studies of designs for energy efficient airports.

Turner Corporation, one of the largest construction management companies in the world with a construction volume of $10 billion in 2014, bring out their experiences on completing 50 years of global presence.

This special edition also brings reports on the remarkable and successful Zak events – The 7th edition of Zak Aluminium Extrusions Expo, 12th edition of Zak Doors & Windows Expo, and 13th edition of Zak Glass Technology Expo – which was held from 10 - 13 December 2015 at Mumbai.

With lot of hopes and expectations to enlighten all our readers by the light of knowledge and information for a better future, we present the first edition of 2016 to you.

Fenestration Feature Behind the Scenes: Successful Window & Door Installations About the Author:

Robert Höllrigl President - R&D Encraft India

Robert Höllrigl, President of R&D at Encraft India Private Limited, advised the company since 2006 and joined full-time in 2013. His involvement in fenestration covers more than four decades. The uPVC framing is relatively new in India and therefore surrounded by myths, contradictions and exaggerated marketing claims. The uPVC window industry has thrown into the self-generated confusion, product attributes which are actually applicable to other continents and glorified emphasizes of product features which are totally superfluous for the Indian subcontinent whilst stringent fenestration assessments are not adequately addressed. This article is the second one in this series.

For general public, it is unimaginable how much effort, skill and know-how is required nowadays to fill a hole in the wall with any window or door frame. There are numerous vital, virtually unknown steps, applicable to all frame materials, before a window or door frame can be actually manufactured and installed.

In the new build market, most uPVC window companies when receiving an inquiry or an invitation to tender for a sizeable window and door contract fall into a state of euphoria and excel themselves in providing comprehensive computer generated quotations almost instantly.

In the new build market, price matters foremost but surprisingly after the first price submission, questions like “Do the frames cope with the local wind pressure?” or “What hardware has been quoted?” lead most of the time to a re-submission of the prices because the interpretation of the fabricator and the expectation of the architect/

l 6 WFM YEAR-END SPECIAL 2015 l

An architect’s vision, a surveyor’s nightmare, a fabricators head-ache and an installer’s challenge!

contractor sometimes differ. Tender clauses or specification pointers like the fame rigidity/strength shall comply with IS 875 - 3 wind loading for the location or hardware shall be corrosion resistant

to BS EN ISO 9227 and BS EN 1191 life cycle tested to 20.000 cycles, will safeguard the client and will automatically enable the fabricator to offer a solution based on performance instead of price. India is not alone, competitive frame prices are being requested/demanded all over the world.

Succeeding with fenestration products in any new build market is primarily based on “getting it right, first time!”

In the replacement retail market, every uPVC window company has its own comprehensive window and door specification covering wind loading, safety glazing and hardware in order to provide a genuine 10 year product warranty. The frame prices include the complete installation as well and can be forwarded as an indicative offer. The final price is normally established after a survey of the apertures and the fabric of the building. It is a fact that every property and every country have their own installation peculiarities.

For example: When you mention to a German installer that the frames are fitted from the outside and pushed against the internal plaster-line (UK method) he thinks you are crazy whilst a British installer cannot comprehend to install a uPVC window frame with a stapler (US method).

Installing window and door frames all-over the world requires knowledge of building details, practical experience and common sense. Retail surveyors are expected to highlight risk areas and check also the actual suitability of the ordered/ quoted frame types and styles. In many cases, requirements and regulations have changed over the years leading to a change in fenestration.

For example: Window cleaning could be a new customer requirement and the existing frame type may not be suitable or the requested convenience additions like fly screens, louvre shutters and builtin blinds, which may impose new, unexpected challenges.

In the new build market, it is naturally assumed that the fabricator can produce ‘finished’ frames from the drawing sizes and/or frame schedule.

But as a word of caution, I still would check the opening sizes prior to commencement of

Exploring boundaries - unique mosque door in uPVC

manufacture regardless of any assurances.

Aperture sizes can vary from floor to floor and from apartment to apartment. (Note: uPVC framing started its success story in the replacement market, this is why one-offs or individually sized frames can be fabricated cost effectively without sacrificing manufacturing efficiencies.)

In the replacement retail market, a thorough and accurate survey is absolutely paramount to establish the replacement frame sizes. The survey will require occasionally the removal of wooden trims, claddings, tiles and render to establish the correct frame size for manufacture.

Checking the surrounding aperture for defects

l YEAR-END SPECIAL 2015 WFM 7 l

Learning from others - suitable survey and installation guidelines

i.e. crumbling brickwork, missing lintel, wiring through existing frames etc. and their rectification needs to be raised and agreed upon at the survey stage. Removing frames which are keyed-in and/ or frames which are seemingly supporting the whole building structure will necessitate additional engineering work which may be outside the scope of the fabricator/installer, requiring the involvement of other specialist trades.

In the new build market, aperture details and frame handing are well defined on the architects drawing and after checking the actual aperture sizes on site (my personal recommendation), frame manufacture seems straight forward thereafter.

In the replacement retail market, the surveyor is the sole (and lonely) company representative who confirms the frame types, establishes the manufacturing sizes, confirms the frame handing, defines the installation method and proposes any building repairs/improvements. Every window surveyor is walking daily on the borderline between success and failure. This occupation has earned my deepest respect because of the responsibility, judgment and trust we place on the correct survey information. But unfortunately,

mistakes can happen easily, surfacing weeks or even months later. Personal example: In the UK twenty years ago, I measured for our new kitchen extension two apertures for tilt & turn windows which were to be fabricated in W.H.Smith’s window division (the company was later known as WHS Halo, Bowater Building Products and VEKA UK). The window division was headed up by my lovely wife, Maja (in Indian, Maya).

Anyway, it was a straight through opening, like most of the Indian new build apertures, but I got one of the width dimensions mixed up. Instead of writing down 1248 mm wide, I wrote down 1284 mm and as Maja’s installation manager came to fit the frames, he discovered the problem, one frame was 36 mm too wide! He instantly rushed back to the factory (He naturally assumed the factory got it wrong!); Maja found my survey sheet to check the sizes and found the wrong dimension (!!!); the remake got instantly recomputed and rushed through the factory; Maja re-ordered the replacement double glazing unit which got made and delivered in record time to our house; the boys in the factory managed to salvage the tilt & turn gearing and as I came home later in the evening both frames were installed, looked good and functioned extremely well, as expected. As I found out, I could not

believe my silly mistake hence my ongoing admiration of surveyors who are being daily confronted with new challenges. The utilisation of electronic devices and the assistance of a second (trainee) surveyor can also help to avoid costly mistakes. Taking, three width and three height measurements to establish the tightest spot of the aperture plus measuring the diagonals to determine the ‘squareness’ of the opening is actually a simple surveying routine but suggesting how to make good and which installation materials to use requires in depth knowledge and experience.

Another common survey downfall is related to the handing and the viewing position of the frames. In Central Europe, all frames are viewed from the inside whilst Great Britain and Ireland views the frames from the outside. In India, you will find both methods adding unnecessary complications to the already complex surveying job. Fortunately, every company can decide for themselves and can adopt their own methods. It is even more concerning when there is an official British Standard BS 7412:2007 and a British/European Standard BS EN 12519:2004 which are in direct contradiction. For example: In BS 7412:2007 the pinnacle is pointing towards the hinges (pointing away from the handle) and in BS EN 12519:2004 is pointing away from the hinges (pointing towards the handle).

Adding more information onto survey sheets could be advantageous like drawing the handle position and the hinge position as well plus mentioning

l 10 WFM YEAR-END SPECIAL 2015 l

especially in a separate title box ‘OPEN-OUT’ or ‘OPEN-IN’, just in case!

Clarity of the required information is key to success in any business. Ambiguity, room for interpretations and relying on some one’s memory will always endanger the final outcome and/or result. In the window industry, justifiable pricing, correct frame specification and accurate aperture survey are contributing largely towards successful window and door installations.

Energy Considerations in Rear Ventilated Façades

About the Author: Chandra Shekar, Senior Manager – Application Engineering and IT, FunderMax India Private Limited

Chandra Shekar is Senior Manager – Application Engineering and IT at FunderMax India Private Limited and has been associated with the company for the past eight years. He is a Mechanical Engineer by profession and has been in the Façade Industry for the past 14 years. He has trained internationally with prime focus on System Design.

With the advent of Global Warming, energy efficiency and conservation have become paramount factors when designing a building. A typical building contributes to 40 percent of the total power consumption today. As an interface between indoors and outdoors, the façade plays a significant role in the definition of a building’s energy efficiency. By employing a rear ventilated façade, an energy concept can be developed for each building that takes into account the heating and cooling requirements of the building along with the perfect light quality inside it.

What Exactly is a Rear Ventilated Façade?

Rear ventilated façade is a multi-layer building façade system consisting of a rainscreen cladding on the outer layer in combination with a frame, weather resistant membrane, insulation, sub frame and a ventilated cavity. (Image 1) A differential between the temperature on the face

l 12 WFM YEAR-END SPECIAL 2015 l

for applications with plaster, glass, hewn stone or ceramics. (Image 2) How Can a Rear Ventilated Façade Help in Reducing the Energy Consumption of a Building?

Rear ventilated façades with their inherent airflow provide a number of distinct advantages over other façade systems such as:

Image 1: Rear ventilated façade is a multi-layer building façade system

of the cladding panel and the air cavity temperature creates a variation in air density, resulting in a “chimney effect” that produces upward airflow within the cavity.

Materials which can be used for rear ventilated façades include HPL and fibre-reinforced resin composite panels, fibre cement, rock wool, ceramics, fine stoneware, copper, titanium zinc, aluminium composite panels, aluminium boards, bricks, façade-quality fabrics and support panel systems

• Thermal Insulation and Energy Savings - The rear ventilated façade system can be designed for various energy requirements, with individually measured insulation materials of any desired thickness. Thermal bridging is reduced because there are no interruptions caused by floor slabs.

Options do exist to help reduce the amount of thermal bridging introduced or even eliminate the thermal bridging altogether by truly insulating continually across all structural members with not breaks or bridges in the insulation except for the finite fasteners used to attach the cladding to the building. Due to the structure of the rear-ventilated façade, the vapour diffusion resistance decreases from the internal to the external walls. Any moisture from condensation, or accumulated during construction, is channelled through the ventilated space and contributes to a healthy and comfortable indoor climate. The insulation also ensures the highest possible heat retention values for the structure, while it compensates high temperatures in the summer from within, thus resulting in reduction in the heating/ cooling requirements in the interior of the building.

• Acoustic Insulation - Rear ventilated façades positively affect the sound insulating properties of the external wall. Depending on the thickness of the insulation, the dimensions of the cladding and the percentage of open joints, the sound reduction index can be increased by up to 14 dB.

Image 2: Components of a rear ventilated facade

l 14 WFM YEAR-END SPECIAL 2015 l

• Environmental Protection - Rear-ventilated façades are resistant to driving rain. Moisture is quickly removed through the ventilated space between insulating material and cladding. The rain protection of the rear ventilated façade works

on two levels: The ventilation gap functions as a pressure compensation room, which ensures that, in a worst-case scenario, driving rain is drained over the back of the cladding, thus protecting the thermal insulation from wetness. Hence, it is possible to construct rear ventilated façades with open, horizontal seams without decreasing the protection against rain.

What Energy Parameters Need to be Considered before Designing a Rear Ventilated Façade?

For overall façade design, the following general parameters should be considered: • Architectural requirements / restrictions • Thermal performance to be achieved (U-value, g-value, layer temperatures) • Flexibility (adjustable performance) • Interaction strategy with HVAC systems (extract rate, natural ventilation) Apart from these parameters of a more general nature, the following more specific parameters may prove to have significant impact on possible design and, therefore, thermal façade performance: • Loads • Maintenance (interior or exterior) • Element module size • Investment vs. running costs (integrated view) In the following, however, we will focus on one of the main thermal performance parameters: the U-value from a façade contractor’s point of view.

What is U-value and How is the U-value Calculated?

Image 3: A multi-layer rear ventilated façade – Cross section

U-value or Thermal Transmittance is the heat flow density going through one squire metre of a specific wall element when both sides of the wall are subject to a temperature difference of one degree K. U-value gives a measure of the heat loss in any building element such as a wall, floor or roof. It can also be referred to as an ‘overall heat transfer co-efficient’ and measures how well parts of a building transfer heat.

U-value measures heat loss by all three heat transfer modes: conduction, convection, and radiation.

U-values are important because they form the basis of any energy or carbon reduction standard. In practice, nearly every external building element has to comply with thermal standards that are expressed as a maximum U-value. The lower the U-value is, the better the element of a building as a heat insulator.

re-working later on in a project. It allows the designer to test the feasibility of their project at an early stage to ensure whether it is fit for purpose and will comply with regulatory frameworks.

To calculate U-value we first need to find out the thermal resistances of each element (R-values). The R-value is the thickness of the product in meters / Lambda (thermal conductivity). The R-values of all materials used in the application are added and the reciprocal of the resulting sum will give us the U-value for that particular application in the building.

There are different techniques for establishing U-values of walls with rainscreen cladding. They are explained below: a) Detailed Calculations for the Entire Wall: The U-value of the whole wall, inclusive of all fixing arrangements, is assessed by numerical calculation conforming to BS EN ISO 10211.

The result applies only to that particular wall as calculated, any variations need to re-assessed. b) Using a Linear Thermal Transmittance for a Fixing Rail that Penetrates an Insulation Layer:

l 18 WFM YEAR-END SPECIAL 2015 l

A 2-D numerical calculation is undertaken on a section through the wall containing the fixing rail.

The boundaries of the model should be at adiabatic positions, for example mid-way between two rails.

The result is compared with a calculation in which the rail is omitted, so as to obtain a linear thermal transmittance, Ψ, as described in BS EN ISO 10211. That calculation needs be done only once for a given design of rail and penetrated insulation thickness. The U-value of the wall is then U = U0 + (L Ψ / A) where U0 is the U-value of the wall without the fixing rails, L is the total length of rail and A is the total area of the wall. c) Using a Point Thermal Transmittance for a Discrete Fixing Bracket that Penetrates an Insulation Layer: A 3-D numerical calculation is undertaken on a section through the wall containing a representative fixing bracket. The boundaries of the model should be at quasi-adiabatic positions, for example midway between two brackets. The result is compared with a calculation in which the brackets are omitted, so as to obtain a point thermal transmittance, χ, as described in BS EN ISO 10211. That calculation needs be done only once for a given design of bracket and penetrated

insulation thickness. The U-value of the wall is then U = U0 + n χ where U0 is the U-value of the wall without the fixing rails and n is the number of brackets per square meter of wall.

emissivity of 0.9, a 50 per cent humidity and an external wind speed of 4m/s. However the U-value is not always constant and can change under the following conditions:

With a high thermal performance envelope comes the associated responsibility to account for overheating, air quality and ventilation. Such walls will set the complete building on a path towards very low operational energy and sustainability as long as designers, constructors and owners put the remaining pieces in place and provide the holistic thinking to complete the job.

• Change in the External Temperature: Very small influence on the U-value. It does not affect opaque, well insulated walls. For glazed walls the variation is also very small: a curtain wall with a mean U-value of 1.75W/m2 degree K at +10 degrees C outside will have the same value at -10 degrees C outside, and will raise to 1.76W/m2 degree K when the outer temperature is +30 degrees C.

No allowance in U-value calculations should be made for the effect of the rainscreen cladding itself, because the space behind is fully ventilated. The effect of brackets or rails fixing the cladding to the wall behind needs to be allowed for, if the brackets or rails penetrate an insulation layer or part of an insulation layer. As the effect of fixing brackets or rails on the U-value of the wall can be large, even when a thermal break pad is included, their contribution to the overall U-value needs to be assessed by a detailed calculation.

• Change in Emissivity of Materials can have an influence, and it varies depending on the material.

When a material has an intrinsic low emissivity it is difficult to make a difference on the U-value if we reduce it even further.

The calculation model should omit the cladding but include the fixing rails or brackets to their full length.

The external surface resistance should be taken as 0.13 m²K/W to allow for the shading effect of the cladding.

Today, rear ventilated façades are amongst the most popular façade systems. In addition to their functional safety, architects chiefly value the design possibilities provided by the use of rear ventilated façades. These systems are thus less susceptible to damage than other façade systems. In addition, fire, noise and lightning protection requirements can be implemented easily and creatively.

The air in well ventilated airspaces is taken as the same as that of the external air. Accordingly the resistance of the airspace and that of all layers between it and the external environment are disregarded. However, as the cladding provides protection from wind, the external surface resistance is greater than its normal value of 0.04 m²K/W. What are the Parameters that Can Modify the U-value of a Wall?

The U-value is calculated under standardized conditions, usually under an air temperature of 20 degrees C inside and 10 degrees C outside, a surface

l 20 WFM YEAR-END SPECIAL 2015 l

• Wind Speed has an important influence if the wall is a glazed façade, and it doesn’t affect the mean U-value if it is a well-insulated opaque wall.

Conclusion:

Separating thermal insulation and weather protection materials, the design of a façade with rear ventilation is not only structurally advantageous but also allows the use of different cladding to create a range of effects. A wide range of materials, formats, shapes, seams, colours and mounting types are available to turn custom design ideas into reality.

Countless new build and retrofit examples demonstrate how designs incorporating rear ventilated façades address their environments with sensitivity and reflect the character of buildings in the urban space.

Case Study

Navodaya Educational Trust Educational Institution Bangalore Protech collaborated with one of India’s leading architectural firms based in Bangalore, Gayathri & Namith Architects (GNA) to deliver to the Educational community a world class building which is the cutting edge of design.

To meet Navodaya Education Trust’s requirement that its state-of-the-art building be highly appealing and well as conform to the latest green building standards, The design for the facade was conceived keeping in mind the climatic conditions of Raichur which are hot and dry.

The aim was to achieve energy efficiency while maintaining the use of natural light and views that were integral to the design. The constraining parameters that were taken into account in the early design stage were: • Climate (solar radiation, outdoor temperature) • Site and obstructions of the building (latitude, daylight availability, atmospheric conditions, exterior obstructions, ground reflectance) • Use of the building (operating hours, occupant’s tasks) • Building and design regulations The façade system for the building was conceptualized as a double skin façade consisting of a three dimension louver application positioned in front of the internal glass glazing that could provide protection from the sun as well as accentuate the design of the building. The louver system formed an independent façade without any support of the façade glazing. Thermal comfort and glare control along with low thermal transmission (U-Value) and low solar heat gain coefficient (G-Value) were

Navodaya Educational Trust’s Educational Institution

achieved using this façade system. It also ensured that the acoustic performance of the building was improved and less noise was transmitted to the interior of the building.

The individuality of the façade design was the key to high performance. It was necessary that the design process should be overall considering the façade as an integrated part of the building and detailed enough in order to determine all the parameters that lead to better performance.

Designed to provide a sense of peace and tranquility for the students inside, and to meet shade requirements, the material selection was of utmost importance. The material used for the louver application was FunderMax high pressure laminate – 0161 Light Afro décor from the Max Exterior Range of Decors. These panels were chosen because of their sturdiness and functionally due to their low thermal conductance and open ventilated system to provide utmost efficiency for the prevailing climatic condition. Each fitted panel was 2800 X 300 mm in length and width and was 6mm thick. The panels

were placed at an angle of 54 degrees to the vertical and the spacing between the panels itself was kept at 250 mm.

Although the concept of Double Skin Façade is not new, there is a growing tendency from the architects to put it into practice. Its complexity and adaptability to different climatic conditions increase the need for careful design. Each Double Skin Façade has to be designed for a certain building location and façade orientation otherwise the performance of the system will not be satisfactory.

FunderMax HPL panels used as louvers allowed just enough natural light to enter the building without making the interiors too hot. These panels were cut and assembled in full size units beforehand to allow for fast on – site installation.

l 22 WFM YEAR-END SPECIAL 2015 l

The mechanical component of the façade rests on the internal structure via MS plates. These MS plates were welded together and positioned in front of the internal glazing layer. The wooden panels were then placed on the MS plates and riveted.

As the design was innovative and different, it required both craftsmanship and engineering.

The installation of the panels was a humongous task due to the high level of technical detailing involved. The maintenance of the degree of inclination of the fins and the inclination of the MS structure at a particular angle along with the sub structure throughout the building as per the design was herculean. Further getting an independent structure which is not connected to the structural glazing was an extraordinary task and at the same time to maintain the geometrical tolerance throughout the building for its sustainability was a feat in itself.

Therefore, it is of utmost importance to take into account these aspects that influence the inner climate, such as fresh air. As the interest in insulation and airtight construction is growing, the importance of a good ventilation is also increasing. Air circulation, replacing polluted indoor air by fresh outdoor air,

leads to a healthy and comfortable indoor climate.

A topic to really think about …

Each day, the indoor air is polluted by a number of sources; occupants (breathing, sweating), their activities (cooking, showering, heating, smoking, etc.) but also by the building itself and its furnishing (radon, volatile organic compounds, paint, glue, varnish, detergents, etc). Do you know, that a new building has 3000 to 5000 litres of humidity, which has to disappear and that humans during normal activity produce about 1 litre of sweat every day? The concentration of all these pollutants indoor can be 2 to 5 times worse than outdoor levels, occasionally even much higher. We do not see these pollutants, but they are there and they have an impact on our health if we do not take the necessary actions to get them out of our buildings.

With an increasing trend towards airtight construction, there are problems with humidity,

Do you Know • A new building has 3000 to 5000 litres of humidity, which has to disappear and that humans during normal activity produce about 1 litre of sweat every day?

• If the humidity is over 75 per cent for more than 72 hours you will have mould in your house.

• The number of dust mite increases exponentially with the increase of the humidity and that this is the main reason for allergies.

• The concentration of all these pollutants indoor can be 2 to 5 times worse than outdoor levels, occasionally even much higher.

• The CO2 level in an average room will reach the unhealthy level in 3 hours if the room is not ventilated adequately.

• Radon is the most dangerous radioactive gas and it is widely found in houses.

• We do not see these pollutants, but they are there and they have an impact on our health if we do not take the necessary actions to get them out of our buildings.

• 16 per cent of all heath spending is related to the air quality!

CO2 and various other substances staying inside the home as adequate ventilation is not considered.

As a matter of fact, excessive insulation and inadequate ventilation create a dead and stale air which accumulates mites, moulds, viruses, bacteria, as well as moisture and harmful chemicals. It has been proven that breathing larger amounts of these pollutants for even the shortest period will affect our

health. This may cause health problems (irritation of eyes, nose and throat, headache and sickness, among other issues) as well as comfort problems (smells, condensation, and moisture). This is why we must regularly and properly ventilate our buildings.

How to Ventilate?

Humans do need about 20 m³ of fresh air to feel well. Fresh air, full of oxygen, gives us energy, improves concentration and avoids sleepiness. In the past, ventilation was not an issue, as most of the old buildings had their own ‘natural’ ventilation through cracks in the construction. Today, our houses and other buildings are constructed as airtight as possible and architects and builders need to include elements, guaranteeing the indoor air quality is not poor.

Many people still believe that opening windows from time to time is sufficient. However the effect of openings windows is only temporary and ventilation through open windows is uncontrollable and, therefore, wasting energy. In addition, they lead to other problems, such as noise, the risk of burglary, the intrusion of insects… Many buildings are also equipped with air-conditioning systems. People or building operation and maintenance companies are, however, setting these air conditioners with energy savings, which means they are just recirculating already cooled air, without combining it with fresh outside air. As a consequence, the pollutants concentrate inside the room. A controlled ventilation, 24 hours a day, is the only effective and secure solution to obtain a good indoor air quality and a healthy inner climate.

l YEAR-END SPECIAL 2015 WFM 25 l

The A, B, C(+), D of Ventilation In general, there are 4 different ways of ventilating, all of them based on the same three principles:

using electricity. The system cannot be stopped and is therefore less interesting than a demand-controlled ventilation system C+ or D. C: Natural Supply and Mechanical Extraction.

• The supply of fresh air in the dry rooms, such as living room, sleeping room…

• The drive of air through the dwelling via halls by means of louvres in the doors.

• The extraction of filthy air in the wet areas, e.g. toilet, kitchen, bathroom …

These ventilation systems are classified by the way the air is supplied and extracted.

This is a system, which can be easily integrated in new builds and renovation. The installer only has to integrate a minimum of ducts and apart from the regular maintenance of the extraction louvres and the self-regulating window vents no further maintenance is needed.

C+: Natural Supply and Demand-Controlled Extraction.

A: Natural Supply and Extraction.

The most easy and cheap way of ventilating, which does not always respect the standard. The circulation of air happens in a natural way based on the differences in pressure. The air enters the dwelling through adjustable openings in windows, walls or the roof. These openings are adjustable as they can be opened or closed just a little bit. In this way you can prevent the ventilation to go in overdrive during windy days. Some of these openings are self-regulating, which means they determine the volume of supplied air depending on the weather. Slits under doors allow the air to circulate through the dwelling, ending in the wet rooms, where it is extracted in a natural way by means of adjustable extraction openings.

B: Mechanical Supply and Natural Extraction.

Using ventilation system B, the fresh air supply happens mechanically and the air is circulated throughout the dwelling via integrated ventilation channels. The mechanical supply of air results in a so-called chimney effect, resulting in the automatic extraction of air in a natural way. Combining a mechanical supply and a natural extraction, this system can be used to ventilate in a correct way in loud areas or in places where smells can appear. This supplied air can be directed through a filter before entering the dwelling. This kind of ventilation is however barely used in dwellings. Why? The answer is simple: the ventilators of the system are constantly

l 26 WFM YEAR-END SPECIAL 2015 l

The difference between C and C+ is the demandcontrolled extraction, using modulating extraction louvres. The ventilation level is adapted based on the way of living. As the ventilation level is never higher than really needed, energy consumption can be minimized. This kind of systems use a central extraction unit, combined with extraction louvres in the various wet rooms.

Ventilation system C+ combines the constant supply of fresh air through self-regulating vents and the transit via door grilles with the extraction on-demand of polluted air in the wet as well as dry rooms thanks to a central extraction unit Healthbox. This unit has a powerful motor with control modules that can ensure proper ventilation of any connected room at all times. Dynamic sensors measure the extraction air in both the wet and the dry rooms 24 hours a day on CO2 or humidity and/or VOCs and adapt the ventilation level to the needs of the residents in an intelligent way. In this way, the Healthbox® makes a healthy indoor environment possible. Thanks to a new integrated technology, the polluted air is not only extracted in the wet rooms, but also in the sleeping rooms, which is very important to have a good air quality during sleep.

This technology ensures that the house is optimally ventilated according to the residents’ activities. As a matter of fact, you can have

ventilation controlled within the rooms the residents are most present. When they are watching television, the extraction level is raised in the living room. When they go to sleep, the extraction in the living room is decreasing and more polluted air is extracted in the sleeping rooms. Result: RENSON® developed a system that follows the residents and guarantees an optimal air quality in the house.

The supplied air in this setup is not heated. In order to prevent draughts it is better to use self-regulating window vents. The more wind, the more the valve is closing, resulting in the same volume of air supplied at all times. When you are living along a road with a lot of traffic, you can use acoustic window vents.

In this way, fresh air is supplied without having problems with disturbing noise.

Think About Mechanical Ventilation Demand controlled ventilation (DCV) allows air to be circulated according to a building’s use and occupancy. DCV uses sensors to monitor and measure ambient conditions and feed real-time data back to a controller, which adjusts the fan speed modulating the ventilation rate to match the use and occupancy of the building. In this case, ventilation rates are kept to a minimum when nobody is the building or in a specific room. The ventilation is increased when people are entering a specific area of the building. This results in a good air quality in every room of the building and reduces energy in a significant way.

Just an example: if people get up in the morning, they first go to the toilet. The clever sensors of the ventilation system notice someone entering the toilet and immediately increase the ventilation level in the room. When the occupants of the building move from the toilet to the bathroom taking a shower, the ventilation system will detect the increase in humidity and automatically adapt the level of ventilation in both rooms. In the end, when people are going to work, the ventilation will be reduced to a minimum.

System D is based on the mechanical supply and extraction of air by means of ventilators. Both the supply and extraction can be controlled, but you need to have a double duct net: one for the supply in the dry rooms and one for the extraction in the wet rooms. In most cases, systems with heat recovery are used. The supplied air is then heated using the warmth of the extracted air. This system has its advantages in

Today, demand controlled ventilation can even be extended to the bedroom. As the sleeping rooms are seen as dry rooms, in a normal setup only supply of fresh air is integrated, no extraction. The new technology adds extraction to the bedroom, because during the night people are creating a lot of filthy air, reducing the air quality in the room. By extracting bad smells, humidity and other pollutants out of the bedroom, people are guaranteed a good and healthy rest during the night, increasing activity and improving life quality during the day.

some cases, but is also more expensive as you need to have more ducts and you have to take into account the maintenance and change of filers on a regular basis in order to prevent health problems.

Need For On-site Tests on Tested Facades About the Author:

P.Jothi Ramalingam, Director, Winwall Technology India Private Limited

P.Jothi Ramalingam, a management graduate, is associated with the architectural aluminum industry for the last 25 years. Since 1990 he has specialized in setting up and running and aluminum anodizing plant and a fully conveyorized powder coating plant to surface finish aluminum extrusions to international standards. In 2012 he entered into a joint venture with Winwall Technology Pte Ltd, Singapore to set up a performance testing laboratory in Chennai to cater to the ever growing demand of the façade and fenestration industry. Winwall Technology India Private Limited is based in Chennai and in its two years of existence, conducted performance tests for over 55 projects across India and Sri Lanka in its laboratory and half a dozen on site tests for projects in India.

“Why should I get an independent agency to conduct on site tests on a tested façade or window when it has already been tested at a lab and certified?”

A curtain wall façade, aluminium window or door is made up of several components which are cut, fabricated and assembled at a factory before it is installed at the project site. The manufacturers of each component which forms a part of the window would have issued test certificates for their specific product quality but how the component as a part of a system perform yet remains untested.

If the developer chooses to use a window or door system from a system supplier which has already been tested for certain specifications and the test certificates are submitted as proof of performance. However the window fabricated by the manufacturer in the country of origin and

the quality of fabricated window by the approved franchisee in India may not be the same.

The size and the number of windows used in a particular project may sometimes not justify the costs for an offsite testing. Under these circumstances an onsite testing is the only option left to reassure the developer that there has been no dilution in the performance of the system he has chosen while it is fabricated by a franchisee of the system supplier. The structural performance of the system may not vary widely as the alloy and temper of the aluminium used would be more or less identical. However the performance of the window with regard to air infiltration and water penetration is entirely dependent on the fabrication skill of the window fabricator.

the inside of the window in inspected for water ingress after 15 minutes of spraying. The same blower is also used to suck air out of the chamber through an air flow meter connected in the pipeline to measure the air infiltration.

For onsite testing of curtain walls, skylight and shop fronts AAMA 501.2 are the recommended method. This method involves spraying water on the vertical and the horizontal grooves of the curtain wall system using a specially designed calibrated nozzle at 30-35 psi pressure. The nozzle is held 305 mm from the exterior surface of the curtain wall and gently moved on the groove line for 5 minutes to cover 1.5 mts length.

Thus it may take around 25 to 30 minutes to cover all the groove lines within the identified sample area.

An onsite testing is also a process specified by the developer to ensure every window delivered to his site matches the performance specified by the consultant and it is installed with due care. As the windows are installed in the project an onsite test is conducted by a third party agency on a random window identified by the developer on a progressive basis. If there are any failures identified during the test, then the cause of failure is analysed and corrective action is done on all the windows installed and adequate care is taken by the window fabricator during fabrication to prevent such mistakes.

On site testing for windows and doors is conducted as per ASTM E 1105 or AAMA 502.02.

Both these specifications recommend an air and water test using two methods. The most common method used is to construct a small temporary chamber using aluminium frames and 6 mm plywood to enclose the window from the inside of the building. This chamber is made air tight. An array of nozzles is installed 400 mm (see diagram 1) from the outside surface of the window. Water is sprayed on the window at 30-35 psi. A negative pressure is created inside the chamber using a blower and

A third party agency specialized in on site testing would be able to conduct the test without any bias and submit a detailed report on the results of the test with photographs and a clear method statement of the process followed for the record.

The results of the test can be analysed by the faรงade consultant in the case of failure and the root cause identified and thereafter corrective action taken to prevent further such failures during the execution of the rest of the project.

intent. A thoughtfully designed skin can make a new building work wonders, through efficient performance for its users and the environment, and the architects have displayed a similar intent in the airport designs.

Furthermore, the façade of such buildings that require consistent energy consumption, not only give shape and add an impressive elevation to the structure, rather it is on the efficiency of such facades (calculation of heat flow) that HVAC equipment and system sizing is based on. If a façade system helps the building with less heat gain, the airconditioning system uses less energy in order to cool the building; therefore an energy efficient façade needs to have a high thermal performance.

Architecture thrives on creative ideas and bold solutions that fascinate and surprise the

user’s experience each time.

Understanding the properties of building materials before, during and after construction is the key to achieving a high performing façade. However, the actual implementation of these measures requires knowledge and experience in the exact requirements of a particular airport, as is evident from Creative Group’s style of architecture in each terminal, setting it apart from the other.

The inspiring architecture of Chennai Airport

Architecture at its visionary best exhilarates and inspires. It is a field that embodies design ingenuity, creating places and most importantly imagination.

But today’s architectural buildings are not just meant to be admired from a far; rather they have become this intelligent place of moulding itself in a manner most suitable for its user.

The new Domestic and International Terminals facades are made up of over 40,000 sq mt of glass, equating to 14,000 bespoke panels. Facades need to perform specific functions like monitoring the potential for overheating in summer. To help manage the temperature, the glass is coated with a film which controls the amount of sunlight entering the terminal.

power consumption, very low external reflection and very high transparency was the perfect solution to wrap the world-class terminal with.

Each facade is predominantly glazed to allow greater transparency through the building and clear views of the airfield and the surrounding city side. Maximizing the use of natural light also contributes to the energy efficiency of the building. Further, the Double Laminated DGU (86.4 - 24 68.4) is the glazing combination that provides suitable acoustic comfort to the passengers within the terminal.

The efficiency of the terminal can be attributed to its meticulously planned spaces.

The H-shaped plan is what forms the very genesis of this sustainable terminal.

Not only did it bestow the passengers with green landscape views, breaking the monotony created by security processes inside the busy airport, but also ample daylight reached every nook of the building. This planning strategy clearly exemplifies that “Even Big can be sustainable”.

“Further, the planning of the airport is laid on the foundation that as sustainability is

sowed, sustainability will grow. By implementing facets of sustainability in every quarter of building design and planning, the green terminals are pillars of sustainability,” explains Ar. Gurpreet Shah, Principal Architect, Creative Group The airport has prudently used glass to create a visual treat while being functionally superior and ultimately enhancing the user experience. The high performance glass provides excellent solar control that increases occupant comfort and reduces traveller fatigue,

air conditioning & artificial lighting cost. Also, the coloured & lacquered glass, SGG Planilaque, greatly adds to the aesthetic value, making the Chennai International Terminal, truly international.

Not only inspiration was taken from the traditional sustainable strategies, but also many new innovations in design and construction were carved on the way. The resultant is a path breaking terminal, with unmatched parallels in sustainable design successful through the incorporation of an intelligent façade system.

The Avian Raipur Airport

Raipur airport terminal

The integrated terminal is an elegant modern structure defined by a high-tech aerodynamic building offering a smooth transition to its passengers from the flight to the city. Its organic form deriving its genesis from an “Avian” is conceived with a sliced dome at the centre and multiple wings elevating the roof profile towards the sky.

The slicing of the roof profile maximizes the daylight, while emitting light in the sky making it visible at night. The design of the terminal building, liaise emphasis on the vastness of spaces, the visual experience of the sky and the subtle landing on the ground with the terminal

building as catalyst integrating all three.

Integration of an efficient façade glass and skylights that act as an extension to the glazed envelope further accentuated through reflective metal panelling supported on steel frames, enable the terminal to achieve large wide open spaces with natural light in abundance. The architects vision and creativity in double curves have been creatively realized through the designing of the glazed aerodynamic.

accommodating a largely span spaced roofing system and the curb side canopy done with polycarbonate sheets, lends an extremely symbolic and high-tech appearance to the built form. The rear side of the air-side corridor is designed to be evolved from a “spaceship” which is attained using a louvered tube form.

“The façade treatment of any structure is designed and executed to meet appropriate facilities for maintenance in the long term. Quality of supervision, adherence to specifications and coordinated efforts from a qualified façade engineer is most important

The most prominent structural feature for the New Integrated terminal is an arching, sweeping roof that spans the entire length of the terminal.

However, it is alarming to note the sudden movement of adoption of curtain walls from the west, irrespective of the climate condition of the region.

Hence, any architectural building, any diverse design is one which mimics the climate and its very moods, moulding itself in the most appropriate manner for the user. And one component that can truly give shape to such a structure is the intelligent design and execution of the faรงade/the skin of the building.

Gone are the days when airports were nothing more than a stopover between the journey and destination. Today, with cross-continental travel being stressful enough, airports need to create an atmosphere of calm & comfort, a place where one can reduce the fatigue & stress that comes with travel.

And The New age Airport designs, along with efficient faรงade designs, are bound to do just that.

Fenestration Industry: Past & Present The fenestration industry in India witnessed a leap in the 90s with an incredible growth in economy and the rising demand of the housing sector. By end 90’s the sector had to follow the ups and downs faced by the construction industry, which in turn depend on the state of the economy. However, the first decade of this century, a slowdown in the housing and real estate sector caused a setback to the doors and window market. As a few positive signs of growth in the real estate sector become visible, the doors and windows market is expected to grow in the near future.

Saket Jain, Business Head, Fenesta points out that the Indian fenestration industry is directly linked to the construction industry’s performance. The slowdown in the construction industry in recent times have resulted in a setback in the window industry. The overall growth is around 20 per cent annually. He observes that retail is still on a steady growth path, though project business has shown a slump in the last couple of years. Jain is optimistic since there have been positive sentiments in the last few months.

Farid Khan, Director & CEO, Profine India Window Technology Pvt. Ltd too agrees that 90s witnessed rapid growth in the demand for doors and windows along with growth of real estate sector and the growth kept increasing since early 2000. “We have seen a boom in this sector in the mid-2000 and now we are witnessing steady growth,” says Khan. India is in a

phase of huge projects announcements, especially from Government, like 100 smart cities, which provides huge opportunity for doors and windows industry. For Khan, all this is a sign of a more fruitful environment for fenestration industry.

Robert Höllrigl, President - R&D & Maja Hoellrigl, President - Marketing & Operational Systems, Encraft India Pvt Ltd too state that the real estate boom of 90’s continued for almost a decade, especially when lot of housing societies came up in different parts of Delhi and when the culture of multi-storied apartments started. “Though the phase of such boom in multi-storied apartments have fizzled out in cities like Delhi & Mumbai in the last few years, the same has shifted to Gurgaon, Noida, Lucknow in North Pune, Lavasa, Powai, Thane etc., in west and also to cities like Chennai, Bangalore, Hyderabad in south, where the culture of multi-story apartments had picked up”, says Robert.

Mario Schmidt, Managing Director, Lingel Windows & Doors Tech (P) Ltd also agrees on the present slump in the construction sector. “With unsold assets of upto 30 per cent, developers are under extreme pressure, especially in NCR and Mumbai. This has affected fenestration sales too,” he adds.

According to Smita Limaye, Project Technical Support, Ege Profil Tic. ve San. A.S. – Deceuninck, the demand for the products are much higher in the Tier 2 and 3 cities than the metros. The 2008 -09 collapse forced builders/developers to move towards suburbs to offer low-cost housing, which saw a fall in window prices and specifications and this is expected to continue for the next 4-5 years. Better connectivity of these towns and cities have greatly helped the fenestration industry to reach out to the hinterland in India.

William Chen, South India Zonal Manager, Kinlong Hardware

William Chen, South India Zonal Manager, Kinlong Hardware observes that in the past 5-10 years, demand for traditional steel and wooden doors and windows were decreasing while Aluminium & uPVC products were increasing.

As the standard of living is improving in India, there is more demand for new apartments and consequently for better doors and windows. But it is still in a nascent stage since consumers have relatively less knowledge about latest products.

Ten years back, more than 90 per cent of doors and windows were wooden and now aluminium and uPVC doors and windows are becoming more popular. There are few new products like tilt-andturn, and sliding folding series in the market, but enquiries are comparatively low.

Arun Sharma, Managing Director, aluplast India Pvt. Ltd, finds that the quality uPVC fenestration solutions

market is still growing at a good pace and he hopes that it will continue to do so.

However, Rajiv Gupta, Secretary, uPVC Windows and Doors Manufacturers Association (UWDMA) observes that there is a slow-down in the uPVC sector since projects initiated by Government and private sector are sloppy.

Narendra Patel, Managing Director, Torfenster System India Pvt Ltd says that in 90’s the definition of windows and doors were different. It was just a necessity. Now home designers are considering different benefits of the product too.

Jean-Gabriel Creton, CEO, Euradif also agrees that there is a strong interest in the PVC segment in

India. Decorative doors panels for entrance doors in PVC and aluminium have been used for more than 20 years Europe. The demand for this concept is catching up in India.

Based on the comments from all the industry leaders, we can come to an inference that with huge projects announcements from the Government like 100 smart cities, and with the propositions by the Planning Commission to build over 20 million new houses to be built in the next 10 years, the real estate sector in India continue to seek greener pastures, thus the related segments, including windows & door market will vroom again, though the past 10 years saw a slump in sales. It is also evident that, with huge number of multi-story apartments coming up, even in tier 2 and 3 cities, demand for traditional steel and wooden doors

per cent and that of uPVC is at about 5-7 per cent.

In Europe, the share of uPVC as profile material is much higher at around 55 per cent. Smita Limaye of Deceuninck observes that Steel also has a share of about 25 percent.

and windows were decreasing while Aluminium & uPVC products were increasing. Popularity of UPVC products are going to reach new heights in the coming years.

Sales of uPVC, Aluminium, Wood, and Steel Windows & Doors Saket Jain of Fenesta and Robert Höllrigl of Encraft perceive that Aluminium still dominates the market compared to other options with its low cost and varying quality versions. Use of wood and steel have become quite negligible. uPVC has become more acceptable than what it used to be five years ago and the market share is growing. Narendra Patel from Torfenster too notes the same and comments that the need for wood windows is decreasing because of its scarcity, maintenance issues and increased cost.

“As per my information and our internal research with our association UWDMA, the size of the uPVC marked in India has reached almost RS 1500 crores.

Considering that the overall market share of uPVC in fenestration is about 10 per cent, the fenestration industry would have a size of RS 15,000 cr”, observes Mario Schmidt of Lingel Windows & Doors. We know that for all economical, budget buildings and houses, Aluminium or low quality wood is the main material used. According to Mario, 80 per cent of the market goes to those materials.

Arun Sharma also remarks that in India, the share of aluminium as a window profile material is about 70

l 54 WFM YEAR-END SPECIAL 2015 l

Jain (Fenesta) explains that the Aluminium Window Industry is estimated to be around 50-55 per cent whereas Wood is on the downslide with about 19-20 per cent share. Traditional steel is still used in low cost houses and in rural areas with a share of about 11-12 per cent. uPVC is window industry is hovering around 14-15 per cent and is expected to grow at a steady pace. But according to Höllrigl, the share of uPVC is still in single digit. uPVC windows are better as compared with low segment aluminium, but surely you can get all benefits in higher segment aluminium windows at a comparatively higher price than upvc, says Narendra Patel of Torfenster . Price is a big factor in India. Manufacturers are selling windows at a lesser price to sustain and as a result of that they have to compromise in the quality which is very critical point for upvc window industry. Solution is to increase technical knowledge and never compromise in the quality because of market war. Ultimately it will spoil upvc industry over a period of time, adds Patel.

From these discussions, we could conclude that Aluminium dominates the fenestration market with 50 percent, followed by wood, steel and uPVC hovering around 22 percent, 18 percent and 10 per cent, respectively.

uPVC Vs. Aluminium All industry leaders agree that both uPVC and Aluminium are on par with respect to strength and performance. Though Aluminium is widely used now, uPVC would be the most preferred material in future, with improvements to frame appearance, weathering performance, thermal insulation, ergonomics, raw material efficiency, sophisticated hardware and frame durability. Moreover, it would be more cost effective and eco-friendly.

Smita Limaye says that for certain sizes of uPVC offers better performance in terms of heat reduction, noise and weather tightness. For very big sizes, Aluminium scores better as new extrusions can be produced at lesser cost and in faster time than uPVC. Bigger openings in uPVC lead to bigger profiles, steel reinforcement and heavy duty hardware which may make the window look bulky. Sleek window systems have been launched by many Aluminium system companies which offer floor to roof sliding systems.

Proper orientation of the building/window for such systems is essential – west/south west facing huge windows would be a large heat source.

According to Saket Jain, in recent years, the use of uPVC has grown in popularity due to low maintenance needs. Aluminium is resilient, but can pick up rust whereas uPVC never rots, flakes, rusts or fades. uPVC is also the most durable of the materials available. uPVC frames are constructed to the utmost hardness making it extremely difficult to break or damage.

Aluminium is similar, if not more secure and is considered burglar-proof due to its strength. Besides, uPVC is considered as green material because it can be recycled and helps in reducing use of wood. The energy required to manufacture uPVC profiles is far lesser than that of aluminium. uPVC window profiles are reinforced with steel.

Therefore, the advantage of aluminium over uPVC in terms of strength is offset , says Arun Sharma. In terms of performance, it is advisable to go for quality uPVC profiles as they are well engineered system products coming with Eurogroove etc. which make for more durable and high performing window solutions.

Great door designs- Torfenster

He too stresses that uPVC profiles are more energy efficient, eco-friendly and durable.

Robert Hoellrigl states that the perception of uPVC frames and screens as a week component is a baseless one. It can match the strength of Aluminium and provides a uniquely engineered, sophisticated outer cover to house a well-engineered steel profile which provides the actual strength. Cleverly designed uPVC frame coupling arrangements and/or static bars (also known as Hurricane bars) provide additional strength to cope with wind pressure, security and human safety (passenger loading). High performance is built-in by design into every uPVC frame requiring that the correct components like steel reinforcements, gaskets, hardware and fasteners are used. The material cost difference between solid Aluminium frames and steel reinforced uPVC frames is virtually negligible when the same glass and hardware is being used. The Government’s effort towards CO2 and energy cost reduction will necessitate the introduction of thermally broken Aluminium frames. This will favour uPVC framing even more, says Hoellrigl. Even Aluminium’s well propagated recycling advantage has been matched nowadays by uPVC’s outstanding material properties.

According to Jean-Gabriel Creton, an entrance door has to be solid, secured and appealing. Aluminium is an ideal product from this aspect when coupled with suitable locks, hinges or even electrical locking systems ad biometric readers. The interior door in its

Project by Torfenster

allure needs to be beautiful, original, easy to maintain and affordable in terms of price. uPVC perfectly meets these requirements.

It makes little sense to compare uPVC with Aluminium, says William Chen. Aluminium windows & doors have good fire resistance and with exotic appearance. It is weak in integrity, easily deforms and has weak heat & sound insulation. But use of advanced aluminium can improve these qualities quite a lot. uPVC has become very popular only in the last 5 years. The major issue at present is scarcity of patterns. It’s hardware fittings are not good quality and not diverse. Besides, the recycling technology of waste materials is not good enough, says Chen.

“In my opinion, it is important to compare the right products”, says Mario Schmidt. “Local aluminium sections available should not be considered in comparison between uPVC. For a costumer it is always advisable to have a look at the final product / sample before making any decision”.

A good system in Aluminium and an equivalent uPVC window will have a same performance. It will be finally the costumer’s choice, whether he likes the “metallic sound” of the Aluminium window or the feel of the wood while using uPVC windows.

Both Systems, if designed correctly, are able to meet the structural requirements and create large span openings. In terms of thermal insulation, of course uPVC is much better then non thermal break Aluminium. Thermally broken Aluminium sections are

Farid Khan says that fusion welded corners of uPVC Windows prevents entry of water through joints.

Structural strength can be imparted with careful selection of profile system and thereby suitable for high rise dwellings. But Introduction of uPVC to Indian market has been late and is taking time to create market awareness.

“If we talk about the challenges and solutions”, delves Khan, “then we can say ‘awareness’ is like two sides of the same coin, it is a challenge as well as solution for u-PVC fraternity to create awareness amongst the consumers who still have connection with traditional material like wood and steel”. A possible solution is to inform architects, builders, government bodies etc. about the benefits and advantages of uPVC. India being a tropical country, sees large temperature variations and if manufacturers are to be believed then, uPVC can easily pass off these conditions.

Market Challenges Speaking about the challenges faced by the uPVC sector, Saket Jain of Fenesta points out that cheap imports is still a major cause of concern. Pricing is another important factor in the Indian market. Heavy import duties and competition from cheap Chinese products will always be a major challenge in the market. Market acceptance is also necessary as uPVC is relatively a new concept in Indian market. Most of the windows sector is still unorganised, manufacturing practices nonstandard and, inefficient, resulting in poor quality products at times.

For Arun Sharma and Smita Limaye too the major challenge of window sector is its unorganized structure. According to Sharma, in most cases, window decisions of house owners are more of an afterthought rather than a priority when constructing a house. This results in the decisions and considerations on fenestration choices often being made too late.

Smita Limaye says that uPVC window producers are better equipped with modern machines and factory set up but often treated in par with on site fabricators.

According to her, there is always a huge gap in prices due to the overheads in design, production and management costs.

Due to absence of standards, customers find it very difficult to compare products and understand the price and quality differentials and could end up buying poor quality products at high prices, notes Limaye.

William Chen of Kinlong Hardware too complaints of companies wanting to make fast money, taking advantage of the absence of standards. In the process, the reputation of the industry has suffered damage.

According to Robert and Maja Hoellrigl, the first and foremost challenge faced by the uPVC system suppliers is to make the influencers like architects and end customers understand the difference between a good quality uPVC systems and bad one, since all uPVC systems look alike. The customer is unaware of the parameters that differentiate between good and bad uPVC. Ideally, the product standard would come first and a competent assessment authority would join shortly afterwards to certify components and/or manufacturers. India could benefit from 6 decades of uPVC window know-how, extensive material R&D and proven European (EN) standards, says Robert and Maja. It would be prudent to adopt EN standards as an interim measure until BIS is ready to issue an official standard for uPVC fenestration.

Narendra Patel emphasises on the need for standards such as BIS for fenestrations in India. There should be a regulatory body to maintain quality parameters and improve specific fields, says Patel. As of now it is extremely easy and economical to set up uPVC door & window manufacturing unit involving low capital investment, availability of low quality equipments and machinery. This leads to manufacturing of substandard products.

With the growing number of faรงade and window consultants in the country, the industry will mature

and stress on the quality rather than going for cheap material. With standardisation, the specification on design blueprints too can be unified and this will help the suppliers to go into mass production and deliver it on time. Since the scope is huge, the sooner we bring in regulations for standardization, the better for the industry and the consumer. Delivering high quality products will become possible.

According to Mario Schmidt of Lingel, unorganized situations at construction sites is a major issue. Timely readiness of openings for production and installation is a challenge. It is again almost impossible to make a production planning programme in advance.

Personal effort of the sales person is the key to success in this industry today, says Mario. Providing the best possible service and a personal attention to all possible mistakes will raise the company value. Changes in pricing policy of competitors has positive and negative impacts. There is a slowdown in construction sector and the entire industry is under pressure to work at rates which are practically impossible.

Farid Khan points out that many channel partners/ fabricators face similar problems like tight cash flow, project delay, competition from cheap Chinese material and lack of awareness on part of the customer. The segment needs more informative campaigns to create better awareness. Narendra Patel of Torfenster finds lack of technical knowledge,

Gupta, Secretary, UWDMA feels that much is about controlling and disciplining the fabrication fraternity and profile extruders with an element of transparency.

availability of skilled man power and turnover ratio of the employees as major challenges.

Rajiv Gupta, Secretary, UWDMA observes serious lack of push/exposure with retail sector, lack of knowledge with respect to inherent values the concept offers versus cost are few major challenges.

Price wars and infighting within uPVC players in this scenario of limited demand at this nascent stage is another hurdle.

Challenges in the uPVC Window Industry Faced by the System Suppliers: Robert and Maja Hoellrigl, feel that the foremost challenge is to improve the fabrication standards to match international parameters. Ensuring use of good and right quality of hardware for Windows, correct glazing, correct sealing gaskets etc. is also a challenge. As mentioned earlier, price is a more important parameter than quality or performance in India today, due to which the fabricator tends cut costs by use of inappropriate hardware.

Since the end customer always looks at the complete window or door as the product of the brand, it becomes very important for the system suppliers to ensure that their fabricators use good quality of hardware, maintain high fabrication standards, follow parameters recommended by the company for steel reinforcements, effective sealing gaskets and correct glazing, over and above the application of high quality & appropriate uPVC profile system. Rajiv

Farid Khan of Profine India Window is very optimistic about the future of the industry. The announcement of 100 smart cities, infrastructure projects, increase in FDI and emergence of middle class give a clear indication that door and window market will gather pace and create more opportunities for uPVC segment. Published reports suggest that the Indian uPVC doors and windows market is expected to grow at a CAGR of 7.0 per cent during 2015-2020.

Smita Limaye of Deceuninck expects the fenestration business in our country to touch Rs 15,000 Cr by 2020 and is hopeful about evolving technologies too. The uPVC industry has moved from using lead stabilizers to completely lead free products in the last decade.

High performance window systems with U value less than 1 have been developed though they are yet to enter the Indian market. She expects that the superior products like tilt and turn window, lift and slide, bi-fold, pivoted windows, wave door, tilt and slide doors and many more designs will penetrate the market and would surge by 2020.

Saket Jain, Business Head, Fenesta feels that going by the current rate , uPVC should capture about 25 per cent of the market by 2020, with lot of focus on energy efficiency, solutions to mitigate pollution hazards and better sound insulation.

William Chen and Arun Sharma are confident that the sector will become more organized by 2020. uPVC is poised to achieve a higher and faster market penetration in the years to come and wood, steel and aluminium will become less common.

Robert and Maja foresee that with metros and big cities becoming noisy and getting more and more polluted, uPVC window & doors in particular is expected to become a priority area for the customer segment in middle and upper income group segment across metros and mini metros, thinking about building or renovating their dream homes.

l YEAR-END SPECIAL 2015 WFM 59 l

Mario Schmidt also expects to witness a huge change over the years the next 5 years and presumes that the speed is to continue. He hopes that the development / housing sector will improve, developers will have a chance to use better products, introduce new technologies to finally benefit the buyer. Branded companies, system providers and members of UWDMA would be able to educate the market / consumers, so that the products do not move into the wrong direction, which the low end Aluminium did 20 years ago.

Smart windows with lot of added value like double glazed windows with uPVC frames will take over due to energy efficiency. Their use could reduce a building’s greenhouse gas emissions by half as compared to the use of aluminium framed windows.

Global Window & Door Demand According to a study from The Freedonia Group, Inc., a Cleveland-based industry research firm, global demand for windows and doors is projected to rise 5.9 percent annually through 2019 to $233 billion. Slowing growth in building construction spending in the Asia/ Pacific region (the largest regional market for these products) will restrain demand gains.

Window and door demand will accelerate in higher income areas such as the US and many countries in Western Europe because of rebounds in housing construction. Through 2019, the fastest demand gains are expected in plastic windows.

Even with its deceleration, window and door demand in the Asia/Pacific region is forecast to expand 6.8 percent per annum through 2019, a faster pace than that in any other region.

Rising personal income levels in the developing countries of the region will allow consumers to purchase more modern windows and doors.

through 2019 as housing construction in the country continues to rebound from the sharp contraction it suffered between 2006 and 2011.

China was the largest national market for fenestration products in the world in 2014 and will see its share of global demand rise from 36 percent in 2014 to 39 percent in 2019. China is expected to post fenestration product demand gains of 7.6 percent per year through 2019, a deceleration from the double-digit annual gains of the 2009-2014 period but still among the fastest in the world.

The Africa/Mideast region is also expected to post rapid window and door demand gains through 2019. Growth will be above the global average due to strong increases in building construction spending as well as rising personal income levels that will allow adoption of more advanced building practices, encouraging the use of modern fenestration products.

North America will enjoy the second fastest demand growth of any region through 2019, boosted by gains in the US and Mexico. The large US market for windows and doors is expected to advance 7.3 percent per year

Western Europe, which posted gains of less than one percent annually between 2009 and 2014, and Japan are also projected to see an acceleration in demand through 2019, though growth will still remain below the global average.

The Oval Room Bronze Mesh Laminated Glass Panels About the Author:

Tariq Kachwala Director FG Glass Industries

Tariq Kachwala is the Director of FG Glass, one of India’s leading glass processing companies with a project footprint throughout India and over 20 countries worldwide. He holds a MS-MBA degree from New York University and spearheads operations and new business development in his organization. One of the prominent figures throughout the glazing fraternity, Tariq, as the Honourable General Secretary of the Federation of Safety Glass (FOSG), has collaborated on various industry initiatives such as establishing new quality standards, inventory management and cost analysis and control. He also consults architects, façade specialists and developers on glass functionalities in modern façades and more recently, fire-rated glass and related safety guidelines.

When you walk towards the majestic Oval Room at The Mansion, your eyes will undoubtedly stop at the striking bronze-shimmered glass panels enveloping this beautiful architecture. What started out as a wildly imaginative design concept, now stands as the country’s largest metal-incorporated glass façade. But there’s more to these glasses than their spectacular appearance - they also very effectively diffuse sunlight and provide a massive reduction in solar heat gain, two inherently important but often overlooked requirements in such free-standing structures. This case study elaborates the design features of these glass panels and its journey from concept to reality.

Hyatt Regency Delhi’s Oval Room at ‘The Mansion’ is its newest event space designed to host conferences, seminars, weddings and corporate meetings. Spread over 1,400 Sq m, it is an opulent pillar-free space that can accommodate up to 1,000 guests with an open kitchen setup that translates

live cooking into a theatrical experience, a first for New Delhi. The high ceiling is adorned with contemporary fibre-optic chandeliers and mood lighting. But perhaps most of all, it’s 3.8 m meter, stylish glass panels embellished with a bronze mesh serves as the highlight, flooding the hall with natural sunlight and still reducing glare by over 65 percent.

The Concept The Oval Room at ‘The Mansion’ was conceived as a new event-space structure in the Hyatt Regency Hotel, New Delhi’s oldest five-star property. As Shiv Jatia, Chairman and Managing Director of developers Asian (North) Hotels puts it, they needed “an energising event space situated in the busiest location in New Delhi, showcasing Hyatt Regency Delhi’s inspiration to create innovative ideas”. A courtyard overlooking the main building was the selected location and BauerLatoza Studio from Chicago, renowned for its work in architecture,

planning, historic preservation and hospitality design was appointed as the principal design architect.

From the onset the intent was clear: the building needed to create a never-before-seen statement and everything from the design to the choice of materials had to be absolutely unique and of the highest order.

The Team CR Narayana Rao Architects from Chennai was signed up as the local architect and the interior design work was entrusted to Hirsch Bedner Associates from Dubai, with consultation from designer Michelle Evans, DPA Lighting from UK and MKA from Seattle. Chennai-based Mahesh Arumugam from Meinhardt Façade was enlisted as the façade consultant to supervise the technical feasibility of this experimental structure and the Bengaluru-based Geodesic Technologies was entrusted with the execution of both, the steel structure and the façade. Future Architectural Glass LLC from UAE was appointed as the glass fabricators due to their past extensive experience in executing complicated and large glass assemblies.

set about designing a grand space that would be enveloped with something unique, standing out from the ordinary. Various concepts kept playing to create a “live” façade that was both dynamic and elegant with subtle variations throughout the day. The challenge was to allow a high light transmission to create a bright interior space without the undesirable and characteristic Delhi sun glare and at the same time give a unique sheen to the envelope. Conventional glass tints, coatings and frit patterns would look flat and create either total transparency or part-opacity, both unacceptable. Only a mesh structure would solve the conundrum - and the challenge now lay in integrating this material into a glass assembly.

The Façade Tim Vacha and John Azarian from BauerLatoza Studio

relatively high light transmission of up to 41 per cent. The depth also creates a beautiful threedimensional effect giving the façade the dynamism that was originally conceptualized. This mesh now needed to be protected within a laminated glass assembly for longevity and ease of maintenance.

Ordinary clear glass has an intrinsic subtle green tint that would blight Mandarin’s natural bronze sheen. To counter this, a low-iron ultra-clear glass was selected to effectively preserve its appearance.

PPG’s Starphire® (USA) ultra-clear glass was finally chosen owing to its very high light-transmission (91 per cent) and colour-rendering index (99 per cent) and almost negligible residual colour. And finally, the glass assembly was to be fixed on the main steel structure with Schueco systems from Germany.

The Materials Post a lengthy and painstaking selection process, Mandarin - a woven bronze metal fabric was selected from GKD-Gebr Kufferath AG based in Germany. Mandarin is an intricately woven and flexible metal mesh made with pure bronze strips in its natural lustre (see inset for details). The small opening size of 37 per cent does a wonderful job of diffusing direct sunlight and still maintains a

Rewind to March 15, 2013 in CR Narayana Rao’s Chennai office where all the key design, production and installation firms are deliberating over the challenge of integrating metal and glass together.

Can we combine the lustre that only metal can offer with the robustness and transparency of glass?

This was something never tried before in India at this scale and the very strict project timelines demanded quick testing and specification finalisation to facilitate production and installation.

To cater to the stringent HVAC demand of a low U-Value, the outer laminated panels were converted into an insulated glass unit with an extra inner clear glass lite that also facilitated vastly enhanced

The bright interior space without the undesirable and characteristic Delhi sun glare

acoustic insulation (STC of 44 decibels) and better thermal comfort.

The choice of interlayer was critical to ensure perfect adhesion and durability. Conventional polyvinyl butyral (PVB) interlayers used to laminate simple glass assemblies would not work since their adhesion with metals is extremely poor and a better interlayer technology was needed to ensure the design’s success.

DuPontTM’s SentryGlas® ionoplast interlayer technology was then considered. The chemical composition of SentryGlas® allowed for metalto-glass assemblies due to its substantially superior flow-rates ensuring that all areas of the mesh were comprehensively covered during the lamination process. The clearer appearance and higher Young’s Modulus (300 MPa) and tensile strength (34.50 MPa) served as added benefits compared to PVB interlayers and imparted a strength which could be compared to that of a fully bolted structure. Still, extensive testing was required to ensure that this experimental façade yielded the desired results.

SentryGlas® interlayer was approved on either side of the mesh and two 8.00 mm heat-strengthened low-iron glass lites were selected to encapsulate this assembly, giving a total unit thickness of 43 mm.

Fabrication Detail

The focus now shifted to finalising the glass and interlayer thickness. An important consideration was the higher-than-normal glass height of 3.80 m which could result in the units buckling due to self-weight and consequently distorting the optical clarity of the integrated mesh assembly. Also the right interlayer thickness was needed to ensure that the “gaps” in the mesh were perfectly filled and no air-pockets were created which could result in adhesion failure over the lifetime of the unit. With a wire diameter of 3 X 0.50 mm for the cables and 0.50 mm for the rods, the total mesh thickness was calculated at 1.30 mm. After much deliberation, a 1.52 mm

Post some very extensive stability, integrity and water penetration tests, production commenced at Future Architectural Glass’ UAE facility. Every step of the manufacturing process needed to be carefully monitored to ensure that quality levels were maintained and adhesion values were not compromised. Extensive changes in the lamination process and auto-clave cycles were essential and after some experimental manufacturing, the final recipes and processes were frozen. Says Firoz Kachwala, director of Future Architectural Glass, “The project presented both a challenge and an opportunity to create a unique glass product. It had many firsts to its credit: glass assemblies with new materials, new lamination process technologies and new testing procedures. The extremely high cost of raw materials put us under tremendous pressure to get things moving quickly and with very constrained margins for rejections.”

The units were assembled and shipped in final form to the hotel site from Dubai port and erected on a massive steel-fabricated structure constructed

by Geodesic Techniques. Impressively, the entire structure was completed as per the expected timelines and the result today stands truly as one of India’s modern architectural statements.

years of our presence here, trying to understand the construction market first, specifically the construction management market. We feel that the construction management market is at a very nascent stage here in India, and is still slowly catching up. Developers are hiring international consultants for project management. They think that these consultants are much more empowered to take decisions. We feel that we are one of those people who will bring the desired change to the sector. We have done it internationally and are sure that we will be doing it in India as well.

WFM: Coming to Project management consultancy, in foreign countries you provide end-to-end solutions for projects. What is the scene in India?

JP: Our model remains unchanged in India. We like to provide end-to-end consultancy and we are doing it for our projects. We are providing our services at pre-construction stage, construction stage, and at the hand over stage.

WFM: Do you get the leverage to select your suppliers and other service providers? Does it vary from client to client?

JP: Yes, it varies from client to client, depending up on the scope of work given to us. But on a job that we are there from day one, we are able to select the suppliers, consultants and contractors through proper tender mechanism and make sure that we add value to the client.

Emirates Towers, Dubai

AS: The decision at the end of the day is that of client’s. What we do is we make recommendations, and the clients decides on whom to go with. We keep the whole process very transparent and open without setting any bias and levelling out everything and make recommendations. We have to collaborate with our clients and it is always a united decision that we make.

WFM: Please tell briefly about your ongoing projects in India?

JP: We are doing two projects with DLF: DLF Mall of India and DLF Capital Greens in Delhi. We are also doing the prestigious project, Statue of Unity in Gujarat. We are working on another project for the defence services, which is a confidential one and we cannot disclose the details to the media. In Mumbai, we are doing two projects for Piramal Realty. One is commercial centre and the other one is a residential project.

WFM: How do you project the facades for your signature projects? How is the branding done through the facades?

JP: Facades make great statements. Facades also need to have the sustainability aspects captured on to it. The importance of facades were realised about

multifaceted. Our expert in Facade based at Malasia, Nickey Haize, is managing these jobs very well.

WFM: Do you have any in-house team of facade consultants or do you hire any outside consultant?

AB: We have people, in-house experts, though we won’t call them consultants since they are part of our team. They have done several project including the Burj Khalifa at Dubai. So they understand and know all the details on it, hence we do not typically go to any consultants.

WFM: In all your other establishments abroad, you have directors for every department, which is missing in India. Why is it so? Do you think hiring facade consultants is a liability?

Hearst Tower, New York

40 to 50 years back with the works of one of the greatest among the architects - Mies van der Rohe.

When we talk about Facades, we are doing a project which is very special, showcasing innovative cladding. The whole concept of facade engineering is still in the developing stage in India.

Our project, the Statue of Unity at Gujarat, has a very interesting facade. It has got bronze cladding on its facade, which is very unique. From the technology perspective and installation perspective, and from the uniqueness perspective, it is truly different. Each panel used would be different since we are following the body contour. We all know that the facade and cladding consultant plays a very big role in this project.

Facade is the skin of the project. It should be sleek and iconic. Hiring an expert for the facade design is very important. But budget is always a constraint.

WFM: Please tell us about the current facade design trends?

JP: I must say that aesthetics play a big role.

When you are talking about the unitized curtainwall system, it is where the complexity lies. There is always structural engineering aspects related to it. It is where the engineering part is also related. There are various factors that play a big role. In India, when you look at it, when you

WFM: Please tell us about some of your complex jobs on facades?

AS: We are doing many complex curtain wall jobs in Malaysia and have completed about 183 highrise buildings in Malaysia. Some of them extremely

take a balance approach, for an office building or a residential building, what you have is a twin glazed with a standard insulation. Most of the architects recommend this. I think it is a good solution and is a very practical one too. It is reasonably competitive in most of the weathers and geographical conditions we experience in India. But it does put certain amount of load in the mechanical systems, even on the airconditioning systems. So we need to use it judiciously. Glass is a great material and we have very good manufacturers in India. We don’t need to import glass. All that we need to ensure is that, implementation of best of technologies.

Facade technology is a growing field in India and there is a lot more opportunities for many players to perform. As the buildings are becoming more and more complex in design, many foreign experts including architects are coming in to do these challenging projects. It puts tremendous stress on the contractors also.

WFM: When you are looking at the projects you are doing in India and abroad, do you follow the same measures in same manner in India? Is the budget again an issue here?

JP: We try to follow the same pattern and uniform process regardless of which country we operate from. But sometimes there are gaps. So that is why, when we take up a project, we feel that we are in a better position to implement the necessary changes and client see the value in this, though they pay a little more premium.

l 80 WFM YEAR-END SPECIAL 2015 l

WFM: Globally you have done many wonderful projects and you have taken up many commendable projects in India. As you see the Indian building Industry is flooded with new ideas and technologies, pushing glass processors and glazing companies for new innovations and collaborations. What kind of quality control procedure do you follow while procuring the materials for your projects?

JP: We do the inspection at the factory and do the three crucial test before the materials being shipped.

All these three tests are very important. As far as the curtain walls are concerned, the quality checks start from the factory. Then it is cut and sized and is ready for shipping. Next is tracking the fabrication and the production process and the quality control at the factory itself. Always random tests are done to ensure quality.

When it comes to the site, obviously one need to make sure that installations are in place, and you need to ensure that the site is ready to receive it. I do not recommend that the curtain wall being stored at the place. As soon as it reaches the site, it should be installed well.

Pullman Saigon Centre Ho Chi Minh City

It is extremely important to start the facade work without any delay. The client must realise it too.

The more he leaves the building open, he is actually risking his own project.

WFM: Could you please tell us about the challenges you face during installation of facades?

Agastya Business Park, Mumbai

Then we do the water, fire, wind tests followed by many other assessments that need to be done, which is part of the process.

WFM: Could you please brief on the fire safety measures?

JP: The architect must specify the necessary fire stops, which are essential between the floors. This is the first aspect for safety. The glazing that comes has a panel which could be broken. Glazing comes with a fixed panel or a non-fixed panel which the firemen can identify. These things are of great importance.

When we do buildings, we identify the panels which can be accessed from outside during the event of fire. So it is not that the glass buildings are unsafe and people get trapped. We have to understand this and all the measures have to be taken appropriately.

WFM: What are the usual challenges you face during the construction of facades and fenestration?

JP: The biggest challenge that we face during the facade building is the delay in installation of facade which should be followed very swiftly. The biggest challenge we face is the delay in decision making on selecting a cladding contractor. Because of the delays, facade work does not start even after the completion of 60 percent the building structure. Only if the building is covered, one can start with the fitout work. Facade is an envelope. The building cannot be left naked. Once the facade work is done on time, the productivity is very high. It is an offset process. It is similar to a pre-fab. It is all done off-site.

Mark A. Boyle (Mark): When you look at the facade industry today, we have a very limited market.

There are not many major design projects, since the market has shrunk over the last 8 to 10 years. It is a challenging market right now and it is challenging in number of ways. When we evaluate the facade sub-contractor, or supplier, we first look at couple of things: 1. Their project management team: do they have a team to take on a major project 2. Their engineering capacity and skills to take up the project.

Reality is, until just recently, the major components like aluminium, glass, and the miscellaneous sealants and gaskets, were available in plenty in the world.

But during last eight month, glass has become an issue. Now it is working its way out uniformly worldwide. We were doing the KL tower in Kuala Lumpur, it is a 118 story tower. We had to devide the total work to be able to get enough capacity to do the whole tower. In the US, a lot of fabrication is out sourced to various locations. Vietnam and Taiwan has become very competitive and is a heaven

for fabrication & assembly of fabricated units. We haven’t looked at the Chinese market yet, though they can produce very good products. But they are not good at installation part. We are following the facade market worldwide.

The problem with the market sector or the trade is that it faces exposure to loss. 50 percent of Turner’s loss is due to the facade. Many of the facade consultants around the world are also facing the same problem. US is facing it terribly. We are facing the same problem, whether it is in Kuala Lumpur or in Mexico. It is a worldwide issue which we pay great attention to. I do not see any additional capacity coming in from any major company in this sector.

We at Turner, keep track of major facade suppliers.

If you look at the major suppliers around the world, they all have changed hands. Thus we are seeing more and more consolidation in that fashion. The smaller, privately owned facade companies cannot sustain anymore.

WFM: What would be your advice to manufacturers and fabricators of doors and windows in India?

JP: Focus on quality control which is extremely important, with frequent visits at the sites. All in the business should maintain international standards.

We also strongly urge the local contractors and developers to stop manufacturing the doors and

l 82 WFM YEAR-END SPECIAL 2015 l

Statue of Unity, Gujarat

windows in the job sites. Instead go for good makes and not to compromise on quality. The customers are investing their hard earned money.

So we have to make sure that we give good value to them. Also make sure all the commitments are honoured, and not to compromise on the quality. In India, we need to focus much more on the quality and there is a need for leap frog improvement.

WFM: What is the main factors that differentiate your firm from your competitors?

JP: There are many points which makes us superior.

The two main points are: we are very customer centric and we are very people focused.

ZC: There are always cultural differences which can create obstacles to a quick understanding of what clients want and price sensitivities which vary globally. What doesnโ t change however in our experience is an understanding of the principles of good design. We are finding that more and more of our clients in developing countries seek for high quality innovative projects.

WFM: Is there a distinct preference in design and materials for faรงades of residential, commercial, public and institutional buildings?

Could you please explain?

WFM: Tell us briefly about evolving trends in Faรงade & fenestration designs.

ZC: We are seeing a growing demand for prefabricated modules and construction techniques.

This is driven by economy and speed of construction.

ZC: The faรงade material depends on design which is based on the category of the building being designed.

There is a slow but perceptible shift from the use of traditional masonry towards the use of new and innovative faรงade materials. The concept is fast catching up in India but it is not just for the aesthetic reasons. The new materials offer better natural lighting, air flow and are in line with the increasing adoption of green and sustainable building practices, an essential in current times.

WFM: Please elaborate on innovative materials used for faรงades of your projects ThaneOne and Acropolis? Are the faรงade material and technology used for Indian projects different from those you are doing abroad?

Recent trends show an array of structural practices and lightweight building such as rain screen faรงades and sun breakers, dual wall faรงades and even building integrated photo voltaic though at a very small scale.

ZC: The Faรงade for each of these projects have been designed with different materials, keeping in mind the design of the building. For ThaneOne (corporate real estate project with iconic office space at Thane), it was strip glazing, structural glazing,

WFM: Double façade is being used in many buildings in west for thermal control, but not so popular in India. Why? ZC: A double skin façade is predominantly used in the west to control thermal comfort levels, prevention of condensation and moisture to the interior of the buildings.

However adequate drainage, thermal control and the avoidance of damp ingress need to be thought about more carefully in India. Poor detailing and lack of careful drainage must be addressed in tropical monsoon driven environments.

WFM: Tell us about your recent projects in India? How different are the façade designs of the projects?

Acropolis Mall, kolkata

WFM: Other than glass, have you found any new materials used abroad which could be used effectively in India?

ZC: We are always looking for innovative materials to use for our façades. However we do try to keep costs down, to be resourceful and more sustainable we tend to source locally. The quality of building finishes and methods of construction are always being looked at; particularly the use of steel frame systems.

ZC: We try to be original in what we do. Each centre brings different challenges with it - from project size, site conditions to client expectations. In many ways, retail centres do have characters of their own driven by varying design concepts; however for any given retail centre, we work hard at controlling signage with the integrity of the architecture.

WFM: Considering quality control (QC), what all criteria you look for while choosing glass and other materials used for façades & fenestration for various projects?’

ZC: We are generally seeing an overuse of glass in contemporary architecture in India; Glass is an efficient material with low U values, similar to masonry construction. Coatings used on the surfaces, laminates and secondary skins can help control uncomfortable solar heat gain and glare.

WFM: How are you looking at the plasticity of the material to mould the façade and then the colours and concepts?

WFM:Talking about fenestration, the trends are changing. Could you please provide insight on this?

ZC: There is an underlying beauty in creating simple façades detailed well. However, with retail designs

west, for speed and ease of construction. We will certainly see the use of more of these sophisticated panel systems in India.

WFM: In India, designers generally do not prefer UPVC for their projects; atleast for upper or upper middle size residential projects. What is your observation on this?

ZC: We also find this to be true. In these income classes we see more glass and masonry being used.

This is more predominant in stone and granite clad, lower part of the building where people can see and touch the faรงade. And of course, the difference in material quality cannot be perceived on higher floors, where pre constituted stone and precast is preferred.

WFM: How important is positioning of Windows?

ZC: It is fundamental while considering the external aesthetic of the building faรงade. A simple harmonious expression is preferred, taking careful consideration of the activity or internal use of the building. The building should be an honest expression externally of what is inside - the servant and server space.

WFM: What are the hurdles faced by the building designer while collaborating the view of the faรงade consultant, fabricator, contactors, etc?

l 88 WFM YEAR-END SPECIAL 2015 l

ZC: The coordination of different contractors is always challenging, and the challenges increase with the scale and complexity of the building. An understanding of phasing/timing of these different skill sets on-site and managing this process, both onsite and in our final construction documents, is essential to ensure a well coordinate final product. Not to mention one of the hardest challenges of them all, effectively managing many different people and personalities that come with it.

WFM: What advice would you give the fabricators/ manufacturers of materials and doors & windows, contractors and consultants in India in terms of the following: Upgrading knowledge, commercial variability, quality control and installation?

ZC: Our built environment is everywhere, we can all learn by visiting more places around the world to understand what makes quality buildings and urban centre. India is a rapidly maturing market and has the good fortune of learning from the best examples internationally. This is just why Bentel Associates International as well as other global consultants within the building industry (JLL, CBRE and L&T but to name a few) will always be busy in India.
