The purpose of this study was to gain an insight into the sustainable architecture concept and apply it to residential design in Bangkok. This concept advocates harmony between architecture and man as well as environment. Later, it developed into Green Architecture and Sustainable Architecture. In general, the sustainable architecture concept involves 4 aspects: energy, materials, water and the lifestyle of those living in such a house. It does not imply that a house designed using this concept will last longer than other houses designed using different concepts. The major concern of residential design with this concept is that the house must be comfortable to live in while at the same time expending less energy and water as well as being part of the environment. To study how much energy and how much water this kind of house used, the DOE2 program was used to build a house model and it was compared to a common house of the same size. It was found that the model house used fewer resources and created longerperiods of pleasant ambiance internally. In addition, it passed the criteria used to assess housing. These standard criteria have been proposed by an institution in the United Kingdom. The sustainable architecture design requires fewer resources and thus, it poses little threat to the environment. Moreover, the quality of life of the residents are better. As a result, this concept should be promoted at community and city levels.
