In order to clarify the effects of humidity on subjective comfort and productivity under transient conditions in summer, subjective experiments were conducted. Subjects were exposed to 30C/70%RH for 15 minutes in Chamber 1. Then they moved to Chamber 2, in which 4 different conditions were set, and stayed for 180 minutes. For all 4 conditions, SET* was kept constant at 25.2C. Skin wettedness on left chest and skin moisture on left forearm decreased more at low relative humidity. No significant difference in subjective task performances was found among all conditions. Total rate of complaints at 70%RH was higher than those under other humidity conditions throughout the exposure in Chamber 2.
