Abstract

The purpose of this study is to analyze the state-of-the-art housing cases with passive cooling technologies and to explore the feasibilities for their applications in domestic housing design. Nineteen Leadership in Energy and Environmental Design housing cases from 2002 to 2007 were selected and analyzed their used passive cooling technologies. Besides traditional passive cooling technologies such as site planning according to the sun direction, the use of thermal mass, insulation, shading, below-ground spaces and ventilation, the relatively new technology trends were detected as followings; the use of high performance envelope, operable windows, and geo-thermal energy as the cooling source of heat pumps, increased areas of photovoltaic cells, and the education of the owner and tenants about the adopted passive cooling technologies in a building. Especially, the education may have not been focused in the domestic design despite of its effectiveness on the appropriate operations of passive cooling technologies. The results of this study show their positive adaptations would be beneficial to domestic housing design to reduce energy costs and have cooler housing environments in summer.
