Abstract
The physiological and psychological responses of the human body at the start of air conditioning were explored in a total of four experimental rooms, that is, standard and low-emissivity (low-e) interiors, individually combined with two types of window glass, low-e and regular windows. The results showed that both temperature and PMV decreased faster in the low-e room than the standard room, and such lower values were maintained until the end of the experiment. The difference in window glass specifications more remarkably clarified, the difference in these measured values between the standard and low-e rooms. Among the physiological responses, the skin temperature decreased after subjects enter the room, and the degree of the decrease was greater in the low-e room than the standard room. The temperature of the room with the low-e window glass was about 0.5°C lower than that in the room with regular window glass. Psychologically, the subjects only in the low-e environment felt “cool” over time, and the combination of the low-e window made them more rapidly felt “cool” than the combination of the regular window. To conclude, physiological and psychological responses are strongly influenced by the low-e environmental condition in the viewpoints of transitional and settled periods.
