Abstract
The thermal performance and occupant's behavior of about 1000 detached houses in Tohoku city area and also in Sapporo and Tokyo as references were investigated in winter of 1982 by means of questionnaire and liquidcrystal thermometers. The regional characteristics of such thermal performance and occupant's behavior of houses was analysed by a multi-variate analysis method. The results are shown as follows : 1. It was found that the cities of Tohoku area could be divided into three groups from the view point of thermal performance and occupant's behavior. Aomori and Akita were comparatively similar to Sapporo. Miyako, Fukushima and Iwaki were almost equal to Tokyo. 2. Among many factors of thermal performance and occupant's behavior, the room temperature, hours of heating, heating apparatuses, oil consumption, etc. were different between above three groups. In Aomori and Akita, the living room temperature is higher, the hours of heating is longer and oil consumption is greater than the other groups. In Miyako, Fukushima and Iwaki, the opposite characteristics was found. In the other cities, such factors were distributed between each house. On the other hand, there were little difference in performance level of thermal insulation and air-tightness between three groups, except that only in Aomori, windows usually were furnished with double glazings. 3. Average air temperature in living room of all houses during heating time after supper was 17.9℃. Average living room temperature is more than 20℃ in Sapporo, Aomori and Akita, and was less than 18℃ in Miyako, Fukushima and Iwaki. Especially the living room temperature in Fukushima is as low as 14.9℃.
