Development of the adaptive model for thermal comfort in Japanese houses

This study was undertaken to investigate comfort temperatures and adaptive model in Japanese homes. We measured temperatures in the living rooms and bedrooms, and a thermal comfort survey of residents over a three year in Kanto region of Japan. The residents were found to be highly satisfied with the thermal environment of their houses. Significant seasonal differences were found in their comfort temperatures. The results showed that comfort temperature varied with changes in both the indoor and outdoor climate. The strength of the relationship between indoor and outdoor temperatures justified the adoption of the adaptive model for both prediction and design of control strategies for the provision of indoor comfort.
