A field survey on the living room temperature in terms of residential building types, heating space and operation throughout Hokkaido has been done in 2008 winter. The 879 residential buildings responded to the questionnaire on the types of their building, heating equipments, heating space, operations and clothing style. In addition, they measured their living room air temperature for seven days by liquid crystal thermometer card. Followings are results; 1) Average room air temperature throughout Hokkaido is 20.9 C . 2) Central heating systems are installed in 3O0o of all. In the other houses only the living room was heated with convectors. The room air temperature of the central heating and living room heating is 21.6 C and 20.8 C respectively. 3) For heating operation, ratio of houses with all-day heating is about 3O0o and that with intermittent heating is about 7O0o. The room air temperature of two groups is 21.5 C and 20.7 C respectively. 4) The room air temperature with the convection heating systems is 1 C lower than that with the radiation heating systems. 5) The mean occupant's clothing value in their living room is 0.6 do for male and 1.0 do for female. 6) According to the multi-variate analysis, it is found that the factors such as age and family size affect the living room air temperature.
