The indoor thermal environments of 78 residential wooden houses in 8 cities of Tohoku district were investigated in winter seasons of fiscal years of 1979 and 1980. Eight cities are Aomori, Morioka, Sendai, Sakata, Yamagata, Akita, Kohriyama and Miyako. The results of the investigation are as follows. (1) In Aomori, the semi-vented oil heater with large capacity is used in 60% of the houses, while both unvented or vented oil heater and electric heater (Kotatsu) are used in 74% of the houses in the other cities. (2) Living rooms are heated about from 7 to 9 a.m. and from 7 to 10 p.m. in almost all of the houses. The air temperature at the point of 110cm high above the floor level in the living room is 18 to 25℃ during the heating time after supper. But the other rooms are un-heated almost all day long. The mean air temperature of the living room during the heating time after supper is 22.8℃ when the daily mean outdoor temperature is 0℃. At that time, the mean temperature of the bed room and the corridor are 8.6℃ and 6.2℃, respectively. (3) The air temperature difference between the points of 110cm high and 5cm high above the floor level in the living room is great during the heating time after supper. For example, the temperature difference is 7 to 10℃ when the outdoor temperature is nearly 0℃. (4) The clo-values of the husbands and wives are distributed from 0.75 to 1.50 during the heating time after supper. The difference of the clo-values among 8 cities and the inversely proportional relation between the clo-value and the room temperature could be found in the range of room temperature below 20℃ (5) The analysis by means of the quantification theory III shows that the indoor thermal environments of houses in Aomori and Akita are different from those of the other houses, and especially the houses settled with the semi-vented oil heater have the well tempered environment.
