Abstract
This study is to concern about the effort of architectural practice to realize the sustainable architecture. It is necessary to know about the integrated design method which combines the passive design method with the active design method from the initial design phase. One case study is followed to explain the method. Integrated design starts from defining the project and goal setting, site evaluation, design concept, design optimization, documents and specifications, bidding and construction and post occupancy evaluation followed respectively. In order to construct the sustainable design, sophisticated understanding about nature and its' principle is important and adaptable application of nature and climate depending on location is followed. In conclusion, architects and specialists of sustainable design should make an effort more study.
