Title: INFLUENCE OF CRAWLSPACE DESIGN AND UTILIZATION ON THERMAL ENVIRONMENT IN DETACHED HOUSE WITH INSULATED FOUNDATION FOR MODERATE AND HUMID CLIMATE REGION
Abstract: The foundation insulation has been adopted in the moderate and humid climate region as in cold region. However, very little research is spent on the design policy and the use methods of the crawlspace in this climate condition. In this paper, five detached houses with the insulated foundation located in northern Kyushu, Japan, have been chosen as various cases for research. The heating system, details of thermal insulation and air-tightness in these five houses have been described. The influence of crawlspace design and utilization on thermal environment has been analyzed by using the measured data. According to the analyzing result, the foundation insulation detached house is well applicable in moderate and humid climate region. Furthermore, by the analysis on the thermal environment in winter, it is can be concluded that the utilization of the insulated crawlspace as an element of heating system is effective for this climate condition.
