寒冷地の住宅環境と衣服着装の快適性に関する研究(第2報) : 夏季における住宅環境と衣服着装との関係(佐々木肇教授退職記念号)

Iwate Prefecture lies in the cold region and is geographically divided into the coast area and the inland area. The life of the people is often influenced by various natural seasonal conditions and the severe coldness in winter, in particular, has a great influence. This climatic background may be one of the reasons why a new and comfortable living environment, that is insulated and air-tightened houses, has been spread over the people there since the then Ministry of Trade and Industry and the then Ministry of Construction presented "Energy Saving Standard" in 1980. However, in recent years, compared to rapidly spreading insulation and air-tightness of houses, the clothing of the residents is not necessarily favorable, and in order to live a comfortable life in summer, we have to take clothing environment as well as living environment into consideration. This study is the investigation of the influence of living environment on clothing environment in summer in Iwate Prefecture, and it follows the study on the relation ship between living environment and clothing style in winter. As a result, both in insulated and air-tightened houses and in the houses with traditional Japanese wooden structure, the humidity is low and the temperature is high in the kitchen and the toilet and the temperature and the humidity are low in the living room. Compared with these differences in living environment, clothes the residents wore are similar during the week. The fact that they tended to perspire much for 7.5 successive hours, though they were lightly clothed and Clo value was low, suggests that clothing behavior is much influenced by living environment. The living environment in summer involves a lot of problems to improve such as wearing more clothes to avoid too much cooling in an air-conditioned room, and wet clothes by perspiration in summer may cause the imbalance of controlling the body temperature. To secure the comfort of the clothing life in summer, it is recommended that they should improve the way of life which makes humidity and temperature rise in the living environment and that they should make good use of mechanical ventilation in the insulated and air-tightened houses and furthermore, that they should make good use of natural ventilation when the residents perspire on account of the rise of the indoor temperature and humidity
