Throughout my five years of study in architecture school, architecture to me is no longer about pure sculptural forms and spaces, but more importantly the expression of each building’s identity with a good integration of structure and climatic strategies. Aesthetics is not ornamentation but a poetic expression of structure and functional elements. There is always a logical sequence of steps that the design process could be broken down into and the adoption of intuition only commences when solving specific issues at each step. A piece of architecture should be able to tell its own story.

Biomechanica is an air-right building across the Ayer Rajah Expressway, to complete the loop of watering holes in the One North and Science Park I by bridging the CINTECH building cluster and MediaCorp Campus. It serves as an extension of the green belt streching from the MediaCorp landscape terrace to the Substation to promote a healthier and more sporty lifestyle by providing sports facilities and introducing cutting-edge sports technologies and products. The scope of innovation can cover three aspects of sports technology: digital apps to connect sports lovers in the area, ticketing platforms to manage the bridge, and biomechanical technologies to improve sports products to enhance user performance. Responding to the strategic location between pro-research Science Park and pro-business One North, Biomechanica provides opportunities for knowledge exchange both among reasearchers as well as between researchers and public users. Interaction among researchers is enhanced by the sharing of the hot desk workshop and a shared database. Comparing with the inward-looking Science Park buildings, Biomechanica allows for more communication opportunities with overlooking floors and large shared spaces. While manufacturing is carried out offbridge, showcasing early-stage design processes by making certain workshops visible and seasonal exhibitions of new innovations intrigues the public to try out the new products. On site product trials will give first-hand data feedback to the researchers. Workshops to introduce new technologies such as 3D printed shoes for the visitors will also enhance user experience. In a nutshell, the users are brought closer to product development and sports technologies can be better understood by the public. In total, Biomechanica houses 4 performance measurement rooms with controllable environments and 11 testing labs for researchers. For the public, usage of sports halls can be reconfigured by interactive floor lighting. The total area can serve up to 10 badminton courts. All in all, this arena will become the centre of sports innovation in Singapore. Family and leisure oriented activities will also revitalise One North during nighttime and weekends, thereby increasing the land use efficiency.

Current trend of fast globalisation and the increase of wealthy youth group as the Millenniums together are causing the tourism to shift towards luxurious travelling experience for the young acults. Number of luxurios hotels is rising exponentially, especially along coastline and at near shore sites. The problem of these resorts is that large land or sea area is required and the living environment for coral reefs is threatened. Meanwhile, the shift of energy resource from oil to LNG is causing more and more oil rigs to decommission and to be abandoned. Thus, we make use of the possibility of combining oil rig and luxurious hotel to explore how the wasted structure can be recycled and readapted into an exciting hotel experience with minimum footprint and waste to be more economical and environmentally friendly.

Pg.15

OILRIGRESORT

2017-18


In this design, the oil rig’s original structure is retained as much as possible to be kept as the theme of the hotel. An experience of precarious feeling is designed to be consistent with this theme. For example, all grill-floored walkways and guestrooms are hung from trusses to let the guest feel the unstableness of the thrilling sea. Hotel rooms will be make of recycled Ferris Wheel capsules which provide panoramic view and good enclosure for private living, keeping consistent with the intention of saving material and reduce waste. Permutation studies of fitting different hotel configuration into three types of oil rigs show that capacity could soar up to 564 rooms in a three-legged jack-up rig. To consider not only the capacity/floor ratio but also spatial quality in the hotel, i.e. to provide an atrium (as in typical luxury hotel deisgn) and sufficient distance between guest rooms, the first type of four-legged Jack-up rig is chosen to proceed with the design proposal.

Urban Decentralized Egg Farm to Support Singapore’s Food Resilience & Energy Generation ChickEnergy aims to provide 100% egg production for local consumption in 2030. Being a high carbon-emission system, egg production relies heavily on transportation, including importation of chicken feed and breeder chicken, delivery of egg and removal of manure. 11 decentralised farms are distributed around the whole island, allocated near to populated districts with the highest density, so that the carbon footprint of local delivery can be cut down. To keep consistent with Singapore’s goal of reducing carbon emission by 36% in 2030, it will be a good move to make use of the massively produced chicken manure by each farm to generate electricity using waste-to-energy technology, in order to cut down on the country’s energy reliance on fossil fuels. According to calculation, assume current manure conversion technology efficiency remains, one farm will generate 54600 kWh per day. If 14600kWh is reserved for the farm (Current 0.65M layer farm’s minimum daily consumption is 10020 kWh), 40000kWh extra electricity can be generated. To respond to the new trend of sharing economy, a business of electric vehicles (EVs) is introduced where EVs owned by the farm can be booked and rented by consumers who do not need to buy a car and EV owners can drive to the farm to charge their cars or replace car battery. In this way, 1000 EVs can be supported by each farm daily.

To raise the public awareness of this chicken-waste-to-energy concept and make consumers and visitors appreciate the energy generation system, the proposal is to expose all the services on the outer shell of the layer houses, including the feed silos and auger, egg collection conveyer belt, and air scrubber towers on the roof. Car system is also made very visible to showcase the eye-catching car movement. Even though visitors are not allowed to enter the layer house area, they are able to see all the presentable services and mechanical systems from the outside as well as the visitor centre. Thus, the overall site planning is to have the frontage (visitor centre) facing the neighbouring residential buildings and the back (loading bay) facing the express way and primary road. The digester tanks and energy plants are in the middle to separate the visitor’s side and the chicken’s side. The typology and arrangement of layer houses is responding to the highly dense urban or suburban context to answer to the growing population. The general strategy is to have maximum enclosure for each layer house so that biosecurity is not impeded by the packing and stacking of layer houses. Many buffer zones are replaced by architectural elements such as cavity walls where pipework and ductwork run. Ventilation systems are enclosed with air chutes to filter the exhaust foul air using air scrubber systems. Chicken manure is transferred with a downward duct in each layer house to the underground anaerobic digester tank to be processed. All in all, ChickEnergy achieves higher land-use efficiency by having higher productivity of eggs as well as providing a value-adding function, electric vehicles, to actively react to the economic trend. In this way, egg farming is no longer a primitive livestock farming concept but a contemporary high-tech industry, where systems are mostly automatic, less manpower is needed and waste is more efficiently managed.

Tunnel ventilation with cooling pads and exhaust fans is adopted in the new typology, with the hot exhaust air directed upwards to be filtered in the air scrubber system. The back-up cross ventilation windows are replaced with mechanical air ducts to take in fresh air from the bottom and release foul air on the rooftop. Each layer house has a manure collection duct at the “dirty” end. The distribution of feed and collection of egg are on the “clean” end which also has the cooling pads.

Current typology of layer houses in the form of sheds.

The new typology of layer houses consists of layer houses slotted in side by side in a reverse way. So that the frontages of the neiboughring layer houses are facing opposite direction.

The spatial plan of the visitor centre is to seperate the staff’s office space and the visitor’s space (dining, cafe, viewing platform), but keep a mininal difference in spatial quality standard to ensure the staff also has a enjoyable working environment. Thus these spaces are stacked and arranged in a linear way.

WIND ENERGY HARVEST STUDY

As a part of the alrounded energy generation proposal of the group, wind energy is a potential but challenging part. Wind energy being a clean and renewable energy resource should be harvested but not currently widely used in Singapore. This project aims to examine and explore how potential small scale wind energy generation can be helpful to Singapore in a neighbourhood scale using a typical residential site, West Coast HDB. Turbines designed for low wind speed are identified. As the prevailing wind comes from two directions during the two monsoon seasons in Singapore, average wind speed during each Monsoon season at West Coast HDB area will be estimated using simulation of the district scale, with surrounding buildings within 1km of the site being considered. Zoomed into neighbourhood scale, more detailed wind speed and direction will be simulated and high-wind-speed zones will be identified with both height and plan location. Autodesk CFD 2018 is used for rough estimation of the wind conditions. After simulation, the high wind speed zones are used for the identified wind turbines to function i.e. higher than cut-in speed for each wind turbine type in each Monsoon season. Total production rate is then calculated and evaluated to assess the feasibility of wind turbines at each location.

WIND @ MARINA BAY POTENTIAL DEVELOPMENT

Impact of Building Typology on Neighborhood Scale Wind Environment

Urban Heat Island Effect (UHI) is a worldwide problem as cities are rapidly expanding. Singapore City Center is important to study due to three reasons. Firstly, it is a highly dense area with clusters of buildings of various heights which cause very complex wind conditions. The significant wind types to be considered in the site are the two monsoons and the sea-land breeze. it is near the coastal line where the sea-land breeze must be promised with a certain urban permeability level that needs to be checked. It has also the highest density of people, causing the highest UHI and thermal comfort to be crucial. Existing and potential wind paths are identified through morphological modelling method using geographical information system(GIS) method with the software ArcGIS and the most important wind, sea breeze from southeast direction, is used for the sole wind input. Six typologies are compared in how much area satisfying thermal comfort within the immediate wind tunnel area. In this study, 6 different building scale design is considered and simulated. Quantitative and qualitative analysis is made among the strategies and reasons behind each strategy’s success or failure are understood. it is crucial for the sea breeze not to be blocked by new buildings in the land plots. In the end, it is hoped that this study will be useful for future development at Downtown area.

Six typologies are compared in how much area satisfying thermal comfort within the immediate wind tunnel area. The results show that option 2 with the addition of stepped podium is the most efficient in enhancing wind speed and hence thermal comfort at pedestrian level and option 2 and 4 (stepped podium and separating blocks) are efficient in thermal comfort. This is because these two strategies are responding directly to the incoming wind direction and become the most efficient ways to enhance urban ventilation in Downtown area.

CELL FACADE Cellular facade tries to provide for a better indoor lighting condition by reflect natrual light into many directions and reach deep into the room. The complexity of cell shape should be able to receive adequate sunlight all day long to reach within an ideal lux level range (in this case 300-500lux for office) and absorb solar irradiance through its depth to keep the indoor space cool. More ideally, it should have some overhang to be rain-proof. Each studio member had attempted on 6 cell designs and improved several with light and solar irradiance simulation to reach the desired level. Some samples are shown below and on the next page.

SMILE VILLAGE 2016 Smile Village NUS is a community project in partnership with NGO PSE (Pour un Sourire d’Enfant) in Cambodia and STEP (Solutions to End Poverty) in Singapore. Smile Village is a community development project that attempts to create a “life institute” for the families of PSE students whom are living in the dumpsite slums. The families living in the “Life Institute” will be in a cluster-housing community, which will also provide them the opportunity to move out from poverty by empowering them through values and vocational training. This project is to design and build a playground in the outskirt of Phnom Penh for underprivileged kids and youths from the Smile Village. A preliminary design was done in Singapore then it was further modified in Smile Village after getting feedback from teenagers and staff in Smile Village. The interactive play structure facilitates and helps to develop local teenagers’ teamwork and leadership skills.

The design of Residence Giesing focuses on the formation of co-existence of comfortable private living spaces and communal spaces, and harmoniously respond to the existing surrounding buildings, so as to achieve the fundamental goal of this project, that is to create a better collective living experience to answer to the rising need of higher urban density. Ground floor plan in the site

Collective living encourages resource-efficiency, including tangible resources, such as space, greenery, electricity, etc. and intangible ones, including time and knowledge. To answer to this, five key design strategies are used here in the sequence of scale hierarchy, i.e. from macro scale of site response and building form, circulation management, to outdoor public spaces, communication between public, semi-public and private spaces, and finally minute details including loggias and windows.

To follow the urban tissue so as to keep a modest gesture and not to disrupt the urban composition, the two buildings designed are of comparable height, shape and footprint to the row of houses in the west which is forming a footprint trend. Smaller voids in the north and a larger open space in the south are formed to allow for more sunlight to save energy for heating and lighting.

A loggia is allocated to each apartment right beside the living room and is always facing the south or the west to get sufficient sunlight for better natural lighting and effective saving of electricity for artificial lighting. This could also enhance interaction between indoor and outdoor by forming good views into the greenery. Windows are larger and taller than common windows in local buildings so as to allow for better natural lighting too. With enlarged windows and the loggia as the outdoor area, although the room is smaller than normal apartments to achieve higher living density, it will look less enclosed and the comfort level is promised for the residents.

Rotation of both buildings avoids the formation of parallel alley-like spaces but creates several triangular spaces of different sizes which suggest a series of alternating movements and pauses in the site. Small resting areas are automatically formed along with circulation paths so that space and land, being very limited in the given site, is efficiently economized. Connection and smoothness of movement is also carefully considered in this design by making use of the three major entrances into the site. Path connecting the west and the east gives convenience to the residents to walk across the entire site without having to waste time in going around this urban block to reach the other side. Privacy level is addressed in a hierarchy including private space, semi-public spaces for small community, and public spaces for the neighbourhood. Public areas will be merged with the walking path to save space and encourage communication, which includes an open garden and an outdoor cafe. Shared library and indoor cafe serve as a smooth transition from outside to inside and induce activities. 2014-15
