The final purpose of this study is to propose a thermal performance evaluation method for passive and low-energy buildings that considers the effects of the residents' behavior. As one of a series of researches, we conducted an experiment with subjects for investigating the thermal comfort zone used to the evaluation method. In the experiment, the subjects lived in an actual house without any heating/cooling equipment. They followed a schedule that included movements between the rooms and three types of actions. And they were allowed to change their clothes according to their thermal sensation. Prom the experiment, we proposed the predicted thermal sensation votes (PTSV) as new comfort index. In addition, the PTSV comfort zone with conditions that are best suited to the residents is proposed as "thermal comfort zone of daily life in residence", considering the adjustments by residents.%本報では、既報で提案した評価方法で用いることを前提に、実rn住宅で被験者実験を行い、住宅内の日常生活における温熱快適範囲rnについて検討した。以下に主な成果を示す。rn1）今回検討した既往指標による快適範囲内となる環境は、温冷感rn±0.5以内の申告数の半分に満たないが、7割方は温冷感申告値±0.5rn以内であったことがわかった。
