【 摘 要 】

The purpose of this research is to verify the necessity to control indoor humidity in Southeast Asia, while the setting temperature of indoor air is increased for energy-saving. Therefore, physiological and psychological responses to ambient humidity were studied using subject experiments in a climate chamber where indoor air condition can be controlled at discretion. For easily finding the characteristics of Southeast Asians, two subject groups, hot humid and temperate natives, participated in the test. As a result, this study revealed an existence of the variation in the physiological and the psychological reactions to a change in ambient humidity, regarding hot humid natives. In particular, a surrounding with high humidity tend to reduce heat flux on forehead and humidity acceptability. These circumstances could not be found in the temperate natives. The conclusion drawn from our experiments is that it is necessary to control not only indoor temperature but also humidity in the case of a building where there are occupants coming from hot humid locations. However, it remains a challenge for future researches to investigate the amount of sweating, physiological and psychological responses of the whole body and the influence of long-term acclimatization for artificial environment upon physical and mental well-being.
