摘要：Residents of non-insulated houses in Kyoto were surveyed in the winter, spring and summer of 1992. The surveys measured room temperature and recorded residents' behavior. This study compares residents' behavior in spring, which is conventionally considered a neutral thermal environment, with residents' behavioral thermoregulation reacting to cold in winter and to heat in summer. Moreover, the relationships between room temperature and behavior are presented quantitatively, based on the measurement of room temperature. The results of the survey can be summarized as follows: Since residents customarily heat only the living room, the time they stay there increases in winter. When houses are poorly insulated and heating appliances are inadequate, staying in the only heated room as a means of behavioral thermoregulation increases. Moreover, since even the warmth of the heated living room is inadequate, residents spend more time near heating appliances. Furthermore, since the temperature near the floor surface is lower still, there is regular use of a supplementary heating appliance designed for sitting down with on the floor. Because of the use of these devices sitting on the floor, time spent sitting on a chair or a sofa decreases in winter. Thus the lives of residents in winter are restricted by low room temperatures. However, avoiding heating other rooms and living with seasonal variations in room use are efficient and economical means of achieving thermal comfort.
