Abstract

Thermal environment measurements and thermal comfort surveys were conducted in August, October and December 2020; May and June 2021 in apartment residences in Osaka, Japan. Indoor air temperature and relative humidity were measured. Thermal comfort surveys reported thermal sensation, thermal comfort, reasons for thermal discomfort, and adaptive behaviors. Griffiths Method, linear regression, and probit regression were used to derive neutral temperatures, which were calculated 23.8°C, 22.9°C, and 23.0°C, respectively. The comfort zone was then derived as a function of outdoor air temperature. The gradient of derived comfort temperature function was steeper than those of ASHRAE and CEN, whereas shallower than that of the survey in the Kanto region. This indicates that climatic factors and building performance contribute to comfort zone. The derived thermal comfort zone was compared with thermal sensation votes, which showed a discomfort within the predicted thermal comfort zone, whose reason might originate from higher activity level.
