In order to evaluate ambient temperature for office and house heating, experiments on thermal sensation of bare hands and fingers, and impression of freshness were conducted under the two kinds of clothing condition. Test A: six male subjects selected clothing ensemble to keep thermally neutral sensation. Test B: the subjects wore normal winter clothing. The subjects were exposed for three hours to four ambient temperature conditions of 7°, 10°, 14° and 18℃ for test A and 10°, 14°, 18° and 22℃ for test B. The following results were obtained I the subjects felt their hands and fingers thermally neutral at the ambient temperature of 21℃, which is the lowest ambient temperature for eliminating discomfort due to coolness of bare hands. The subjects felt fresh below the ambient temperture of 20℃, and the authors found that the optimum ambient temperature for freshness was 18℃, accepting slight discomfort of cold hands.
