| Research Abstract |
The present study was undertaken to clarify the relationaships between the thermal environment of the elderly people and psycho-physiological characteristics, and to propose the recommended room temperature and cooling-heating systems for the elderly people. For this purpose, we conducted the survey on residential thermal environments for the elderly people and the experiment on ifluences of thermal environment on physiological and psychological responses in the elderly subjects in climate chamber. In a questionnaire survey on residential thermal environments, the most popular cooling system were the air conditioners, and electric fans among the elderly people who were over 60 years old in summer. In winter, the heating mechanism most commonly used was stove among the elderly people. In the measurements of residential thermal environments in the elderly people residences, the mean room-air-temperatures (Ta) were 27C-29C in summer. In winter, Ta were 15ﾟC-18ﾟC at living-room and about 8ﾟC at bed-room. In the experiments of climate chamber, the skin temperature at the chest (trunk) of the elderly was lower and dropped greater than the young subjects in the same air temperature. But the drop of the elderly's skin temperature at the shin was smaller than that of the younger groups in summer. These suggest than the special attention should be required for an room temperatures to be adjusted properly and comfortably for the elderly. We recommend room-temperature of 26ﾟC-29ﾟC in summer and 21ﾟC-25ﾟC in winter with the radiant heating system at the floor.
