[Abstract]

　Carbon dioxide emission from residential sector of Japan has been increasing due to the changes in living quality and life style. Growing rate of energy consumption from residential sector during 1980 and 1990 was more than 24%. Carbon dioxide emission rate from residential sector is approximately 23% comparing with the whole carbon dioxide emission in Japan, and 12% is household emission.
　As countermeasures to cope with global warming it is important to establish the control and reduction system of carbon dioxide from residential sector.The major purposes of this study were to investigate the reduction system of carbon dioxide emission from residential sector.
　The data obtained from model simulation study , measurement in model house and experimentation on living persons in artificial environmental simulator were analyzed. Forecast the future for the reduction amount of carbon dioxide emission from residential sector owing to the introduction of Eco-house was conducted based on model simulation. Technology assessment for the development of an Eco-house was also conducted.
