Study on Comfort Temperature and Occupant Behavior in Office Buildings in Hiroshima

In this study, we investigated the indoor environment and thermal comfort of office workers in the Hiroshima region, using data from field measurements and questionnaire surveys. Additionally, we analyzed the relationship between comfort temperature and the outdoor temperature, aiming to propose a thermal adaptive model specific to this region. Furthermore, we examined occupant behavior, such as adjusting clothing insulation and taking actions to stay cool or warm, to validate the adaptive model. The findings indicated that individuals who made greater changes in clothing tended to have a wider range of comfort temperatures, providing insight into the mechanisms of thermal adaptation.
