Introduction
Manifesto
The neccessity of sustainable environmental design “Sustainable design is crucial, but why should sustainable assessment be a necessity in architectural design?� People in history have been using buildings as a mean to shelter themselves not only from harm but also displeasure caused by weather. Because of this, vernacular architecture evolved in the way that they would withstand the climate and help differentiate indoor comfort from the outdoor discomfort. While the severity of climate circumstances and condition is getting larger due to the irrefutable global warming, the role of architecture in assisting people to cope with the weather is, in contrast, getting smaller. People nowadays instead turn
to the convenient of technologies which provide energy-consuming solutions for heating and cooling and available within reach of a dime. Although most of the architects were taught to work with the concern of climate condition, the fight to extend the simple yet proven knowledge using rules of thumb will no longer suffice as people do not see the need to acclimate. Without proper tools to evaluate the effectiveness of the methodologies, the guesswork provides no assuring to convince clients. The sustainable environmental design analysis will provide solutions for this issue by using concrete data to ensure them that the solutions are optimum.

01 Rethinking HDB Flat
Applicable Design of Public Housing in Singapore Bedok, Singapore | Singapore In the tropical environment, high level of heat and humidity are primary factors that make air conditioning become a popular yet high-energy-consuming solution for internal cooling for the majority of urban households. With the rising trends in global warming, continued increase in air conditioning usage has become serious environmental concerns over the past decades, calling for the need to rethink of a more sustainable solution to low-energy consuming and environmental-friendly living space.

Pr e f a c e
The dissertation proposed a sustainable, energy-efficient, free-running design solution for hi-rise residential buildings in Singapore. It is based on theoretical studies, simulations and supporting empirical experiments. The proposed approach uses the combination of design and materials to minimise impacts from humidity while leveraging the benefits from relatively mild temperature for cooling. The solution can be achieved through integrating sustainable design strategies to optimise thermal and daylighting performance, with effective moisture control strategies.

possible while hygroscopicity is although unnecessary but desirable. It means that if these building elements get in contact with the water in any form, the transfer of moisture content would be slow or halted, however, in the case that the parts have absorbed water, it is better if they could release the water quickly. Next, it is preferable for typical CONTROL internal walls to have high PASSIVE HUMIDITY hygroscopicity while moderate to low capillarity and permeability are acceptable as their chances of exposure to water are considerably low. the ability to absorb and let water through should be kept at the minimum.

Accordingly, the main selection of materials Fig. 24 regarding their individual breathability requirement are: Material Selection
Accordingly, the main selection of materials regarding their individual breathability requirement are:
Dense concrete is commonly selected for building structures, especially in high-rise buildings because of its strength and handy application. Dense concrete is considered not breathable; it would be used as a structural element and foundation where the impact from water and vapour should be minimal. ● Timber Timber usually absorbs and release moisture quickly, but it does not allow the transfer through. In this project, the main sources of timber are renewable rubber ash and bamboo which grow well in Thailand and Malaysia. ● Unfired Clay Brick Stufy The internal and external walls feature unfired clay brick as the main structure combined with lime rendering and appropriate cladding. Unfired clay brick is similar to traditional brick, but its production using radiation from the sun to dry instead of fire or manufactured heat causes them to have a lot less embodied carbon. They dry quickly and importantly let vapour transfer through. Nevertheless, the capillarity level of unfired clay brick alone is high and therefore a suitable render is needed. ● Hygro-skin This composited material allows the possibility to create the ideal property for external walls. Hygro-skin is a climate responsive material which was a part of FARC Centre Oelean done by a team from The ICD from University of Stuttgart in 2013. The way hygro-skin works is simply by using the property of a thin layer of wood which has a natural mechanism to quickly change its shaped in response to the humidity level. This property in a natural setting could be seen in pine cones which could change their outer skin shape according to the dampness in the air as shown in Figure 25. The application of hygro-skin on the external walls as seen in Figure 26 and 27 would create an automatic adaptability to slow down or stop moisture buffering when the humidity outside gets higher.

Occupant Activities at Shared Balcony
BRINGING PEOPLE CLOSER In a traditional Malaysian Kampong verandas are always the liveliest areas. The shaded spaces are visually connected to streets and used for the majority of daytime activities. The verandas filter the public and private space but at the same time encourage connection
within the neighbourhood. This socio-environmental phenomenon occurs similarly in semi-open spaces in high-density residential buildings. The forecourts which connect corridors and residential units create a strong sense of security and neighbourliness.

02 Urban-Patch
Sustainable Living @ Diespeker Place Islington, London | UK Contrary to tackling a big site and building a mega housing project that may not fit into the surrounding finer scale building typologies, we are challenging ourselves with something small, something leftover and perhaps oddly shaped. These are plots that developers may not find interesting or worth investing due to the small scale or site constraints. We believe that these locations have great potential to stitch together the urban context and densifying neighbourhoods in the least intrusive manner. The building is lightweight as lightweight buildings perform better
in variable climate and have lower embodied carbon. The proposed building design is 30% below the Good Practice total energy consumption benchmark. The estimated annual Co2 emission from heating is 96% below than the Good Practice standard. Flexible spaces have been provided for occupants to perform different activities throughout the day, both for work, rest, and entertain. The rooftop offers a communal vegetable garden space with covered areas under the trellis and PV panels giving protections from the rain and hot summer sun.

We proposed to look into a simple construction system that requires a low-tech system that would satisfy all the requirements of thermal insulation, cold bridging, noise protection, fire protection, security, space dimension standards, etc. In addition, various passive adaptive measures will be implemented to provide flexible control to the occupants.

03 H o l y Tr i n i t y P r i m a r y S c h o o l Design by Architype
Richmond, London | UK This environmental design assessment report on the Holy Trinity Primary School expansion was done within two and a half months. The outdoor and indoor studies comprised of analysing previous studies on the building, interviewing the architect, visiting the site to make observations and measurements, informally interviewing the teachers and staffs, followed by analytical work and simulations. The goal was to analyse and understand the building performance, usability, and occupant comfort to draw conclusions and provide suggestions for improvements if deemed appropriate. Architype was responsible for the design of the Holy Trinity Primary School expansion project. It was a fast pace design-build project with construction started in 2010 and
Keystage 1 (source: Architype) 31
finished in 2011. The project achieved BREEAM Excellent with its use of local sustainable materials and 20% reduction in energy consumption and CO2 emission, etc. The building itself was designed to fit the school activities and to achive high performances of sustainability. Unfortunately, the short period of the study only allowed us to focus on the extension wings. The materials used in this project were chosen carefully. Consequently, the high building performance makes the building very well insulated and which cause the building decoupled from the outdoor which make it easier to archive the thermal comfort and would use less energy for heating. The materials were not only high in performance but also environmentalfriendly and renewable.

Since one of the design goals was to achieve a highly airtight building envelope due to flight noise issues, a mechanical ventilation system with heat recovery ventilation9was installed. The MVHR coupled with the Earth Tube system uses the less fluctuated temperature underground to cool or heat up the outdoor air before letting it into the building, which would help improve air quality while simultaneously improve the indoor temperature as well (Figs. 009-010). Interestingly, Architect Christian Dimbleby revealed in retrospect during an interview that it was not wise to put the Earth Tube System under the building foundation. He noted that it would be better to put the system next to or around the perimeter of the building. This would simplify the construction process and lower cost as well as providing the ability to access the system for maintenance later.
A multifaceted approach was taken to meet these requirements:

INDOOR PERFORMANCE ASSESSMENT The team learned that the building gets overheated in the summer. The high temperature may have been due to user errors such as blocking the vents, as well as causing artificial lights to be on all the time with posters blocking the daylight from entering the room. The high temperatures may
37
also be the lack of manual overrides on the ventilation system, which is operated by automatic temperature sensors. Referencing these studies, we applied a similar methodology when collecting measurements. The collected data also showed that daylight distribution is an issue.
by spot measurements (in the Appendix) and furthermore gger information on Figs. 075-076, the indoor temperatures ee rooms seem to be stable. The figure shows that week 3 w comfort, which may be due to the thermostat being set me temperature compared to the previous two weeks, even he outdoor temperatures were lower than the previous weeks’ ures. MVHR would bring in colder air for fresh air requirement, , causing the indoor temperatures to be below comfort band.
The outdoor temperatures seem to not have a big impact on the indoor temperatures. We can therefore infer that the building envelope’s airtightness is performing well and it is decoupled from the outdoor environment. This decoupling from the outdoor is a good sign for an air-conditioned building. However, the team is interested in looking at different strategies to turn this building H O L Y T R IN IT Y S C H OO L K E Y S T A G E W IN G a toward free-running.

Solar Analysis By looking at Incident Solar
COURT YARD GLAZING The team wanted to test how the existing overhang is performing by looking at Incident Solar Radiation on the glazing, specifically at the south facing façade at the courtyard.

Materials were chosen carefully to match the existing conditions as closely as possible in order to yield more accurate simulations for analysis. Below is a list of the material reflectance used in the daylight model for base case as well as material alteration for the proposed refurbishment case. Simulations were ran to test the performance of the existing daylight conditions and find ways to improve it. Fig. 069 compares the Base Case to Case 1, which is increasing the window to floor ration by raising the glazing by 0,5 meter. We can see that this does have a positive impact on the daylighting potential of the N classrooms, with & a 6% daylightSCHOOL autonomy increase. OLY TRINITY CE PRIMARY NURSERY

PROPOSED IMPROVEMENT SUMMARY The Holy Trinity Primary School is an excellent example of refurbishment with a tight schedule and budget. The Architects and Engineers have achieved a great amount while balancing function and aesthetic. After in-depth analysis, we discovered several things that can be improved if given a more relaxed schedule and budget. These strategies would bring the high indoor temperatures during the warm period into the comfort band and increase the indoor temperature during the cold period by 1-2K. The building would still
need some heating during the cold periods, but the heating load would be reduced. By implementing these refurbishment proposals, the Key Stage 2 Classroom Wing would reduce energy consumption by about 50% from artificial lighting and close to free-running for heating and cooling. Consequently, the school will significantly save operational cost over time and reduce CO2 emissions, while providing students with a more adaptive and natural learning environment.

The project started with an intense discussion between owners and the designers on developing this deserted four storey office building in the heart of Udon Thani. The conclusion to converted this building into hostel came after considering the growth of tourism business, size and interior space, and limitation and potential of the building location. Hostels are getting more popular in Thailand not only because they are affordable but also the friendliness of staff and guests
43
which bring the opportunity to get to exchange idea and thoughts with new and interesting people. Hostels have become unique temporary community space. Bicycles are popular among all ages in Thailand. Udonthani urban concept aims to convert the city to be bicycle friendly as to be more sustainable and for the people's health. Udonthani is also a prime destination of both Trek and Touring cyclist. The project is bound to finish in the 4th quarter of 2017.

04 Laboratory Ramathibodee Hospital Phyathai, Bangkok | Thailand
Laboratory design is a very sensitive kind because it requires the understanding of function and equipment, as well as basic maintenance methods to be able to achieve well-fitted layout, materiality and styles of furniture. The major problem occurred on this project was the lack of this set knowledge by the designers causing the design to fail upon installation. Additionally, the construction work in the hospital is likewise sensitive. The work needed to be scheduled according to the hospital working hours, particularly, to control of the construction noise to the level that it would not disturb the patients, especially the nearby Psychology Department.
Because of these issues, Abbott Laboratories, the main donator of this renovation, hired the consultant to coordinate with the contractor and designer to complete the project correctly and within the deadline. The consultant responsibilities covered; • • • • • •
site and construction work inspection Arranging weekly and monthly meetings with the contractor, the users, and the designers Re-organising work schedule Discussing with the designers regarding design revision Resolving construction and equipment installation issues Prepare documentation

Sukhumvit, Bangkok | Thailand The Swiss-German, Mr Kundert, bought this impressive home on Sukhumvit 34 street, Bangkok Central as a retirement home for himself and his family. While loving Thai culture and tropical climate, Mr Kundert wished to add European sense to the house as to accentuate the identity of his mix-cultured family. The scope of work covered renovating the already in good condition house by featuring exterior, interior and landscape design while providing fitted spaces for Mr Kundert's
beloved collection of Scandinavian style furniture which each piece of furniture has a unique character. To save cost, the structure which was ideally in good condition were all maintained. The designer pulled out the old identity of the existing house and mixed them together with the contrast modern style by displaying the first-floor timber structure and add details of steel frames to reinforce the structure. While keeping the whole skeleton of the house, the atmosphere and appearance have been altered to the clients' taste.

Modular for Diaster Victims Anywhere | Thailand The Plain-Plane house is a part of a research project done for Silpakorn University-based nonprofit organisation, "CPR: Center of Prefab for Disaster Relief". The study aimed to develop practical prefabricated houses which can be built easily and quickly in any terrain and site condition for those who suffer from either natural or humanmade disaster. The Plain-Plane house was developed by RicePopper studio using 2D panel prefabricating system which relies on
load bearing wall structure. The system was picked because; • The variety of component materials • Small panel size can be transported. • The dry-construction system The panel developed in this project is a lightweight framing structure using folded galvanised steel to increase the material's strength. This folded metal frame allow the components to be lightweight enough to be installed without heavy machines.

MODULE MAKES PERFECT (FOR EXPANSION) The Plain-Plane house also allows owners to extend their home if needed. Even though the government will only be able to provide only standard type unit (37sq.m.) in case of disaster. However because the made-to-be-simple structure
65
system can be easily built by the residents, the building materials such as modules and bolts could be purchased later at the reasonable price. This flexibility feature provide the opportunity to extend or rebuild to fulfil Thai expanding family norm.

The lightweight system is flexible to be installed on raised concrete or steel structure platform with beam and column system. It can also be fixed on the ground slab.

06 London Farmhouse Edible Micro City London | UK “When I have bacon, I don’t go home and fry them in my own pan. That way I might get fed, but I’ll take it to the village kitchen and see how many people could be fed” - Brandy Gallagher (O.U.R Eco Village founder) Are we the only intelligent creature? Ants could develop an efficient working system in the colony. The system is simple; ants do not act individually; they behave according to the needs of the colony. Every single ant works strictly on designated responsibilities, and when unexpected events happen, they all together adapt to the situation. Like ants, men used to have "Spirit of Village" which is the way of commune living where the
members of society think about the well-being not only of themselves but the whole community. In Utopia, every year, a group of people would be sent to a countryside to learn how to maintain agriculture land. Each group would spend 2 years working and teaching the new crews. Utopia is a perfect example of how urban agriculture could work; The project aims to deliver an architecture that can fulfil agriculture purpose allowing people to switch from insecure life style to a new way of subsistence living. This EdibleArchitecture uses maximum space efficiency to produce food at its full capacity. Each part of the building is to be used for farming.

REVERSED ENERGY PYRAMID Ecological system is simple yet effective nevertheless. The widely recognised system is the energy pyramid which shows a proportion and relation of and between members in any ecological cycle.

However, using this arrangement directly might not be the answer. Consider energy use in transport food and items up and down the height of the building to flip the system upside down could allow time and energy saving in transportation.
