ANALYSIS OF RESIDENTIAL ROOM TEMPERATURE AND OCCUPANT'S THERMAL COMPLAINT IN WINTER FIELD SURVEY

摘要

To evaluate safety and comfort of residential thermal environment in winter season, field study at 13 residences and questionnaire survey for these occupants were performed around Nagoya city area in Japan. Room temperatures were measured during 14 days, also occupants mentioned thermal complaint for low room temperature and temperature difference among 7 rooms. On the purpose to reveal the relation between room temperatures and recognition of occupants for them, measured room temperatures were compared with thermal complaint. As a result, their awareness for low temperature and room temperature difference were not enough to avoid the risk of heat shock between heated rooms and non-heated rooms. There is the limitation on the accuracy of occupant's recognition for room temperature. Therefore, it is necessary to moderate the room temperature differences in order to reduce domestic thermal related accidents.
