Abstract
The purpose of this study is to clarify the psychological influence of thermal environment on elderly people in their welfares facilities. Two facilities where the elderly people actually used were regarded as objects to conduct the thermo-humidity measurement and hearing survey.
As for actual living environment during investigation time, the range of measured temperature was wider than criteria value of indoor temperature for elderly people in winter and summer. While the range of measured PMV was wider than the standard comfortable value of PMV (-0.5∼0.5) in winter and summer, the elderly people announced that it was neutral for them. Humidity-reaction of elderly people was also duller, and it was also difficult for them to perceive the temperature gradient from head to foot.
