Abstract
In order to clarify effect of humidity on the room temperatures reported to be comfortable, an occupant thermal comfort and behavior survey was conducted for five summers in the living rooms and bedrooms of residences in the Kanto region of Japan. We have collected 13,525 thermal comfort votes from over 239 residents of 120 homes, together with corresponding measurements of room temperature and humidity of the air. The residents were generally well-satisfied with the thermal environment of their houses, with or without the use of air-conditioning, and thus were well-adapted to their thermal conditions. The humidity was found to have very little direct effect on the comfort temperature. However, the comfort temperature was strongly related to the reported skin moisture. Behavioral adaptation such as window opening and fan use increase air movement and improve thermal comfort.
Highlights
Thermal comfort is one of the most important factors in creating more comfortable homes.Investigating and establishing the comfort temperature of the residents can suggest customary temperatures in the house, so as to minimize excessive energy use and save the overall energy costs of the household
The data were divided into two groups: the free running (FR) mode and cooling by air conditioning mode (CL) [20]
In order to explore the variation of the comfort temperature, and to investigate the behavioral adaptation in Japanese houses, we conducted a thermal comfort and occupant behavior survey in houses in living-rooms and bedrooms for the hot and humid season in the Kanto region of Japan
Summary
Thermal comfort is one of the most important factors in creating more comfortable homes. We need to investigate comfort temperatures and the effect of humidity on the occupants of dwellings. We need to construct an adaptive model using thermal comfort survey-data from Japanese dwellings. In hot and humid conditions air movement is an important factor in determining the indoor comfort temperature [15]. Behavioral adaptation such as window opening and fan use can increase the air movement for adaptive thermal comfort. In order to clarify the comfort temperature and investigate behavioral adaptation in Japanese houses we conducted a thermal comfort survey and an occupant behavior survey in the living rooms and bedrooms of 120 houses during the hot and humid season in the Kanto region of Japan
