The floor heating system is regarded to have high profitability in comparsion with other heating system in view of the heat balance and thermal sensation of human body. In addition, Japanese are fond of floor heating, who have accustomed to warm their feet at "KOTATU" in winter season. However, it is also pointed out physiologically that the controlling center of body temperature will be out of order to react local heat such as that of floor heating system. Therefore, it is necessary to experiment what reaction of human body occurs when his sole is heated by floor heating system. The experiment I was conducted to observe the change of body temperatures, thermal sensations and degree of comfort under the various floor heating conditions. The experiment II was done under the un-uniform distribution of air temperature in a room. The results of experiments were as follows. The rectum temperature did not drop when the sole was heated (for example 44℃) in spite of physiological expectation. And the sole temperature did not work on comfort votes in such range of sole temperature as 33-44℃, in case that the subjects were seated with light work in about 20℃ still air for 90 minutes. Under the un-uniform distribution of air temperature in the room the subject felt unpleasantness because of decrease in the lower limbs skin temperature.
