In medical facilities, the aim of room temperature is based on past studies for postures of standing and chair sitting, and on epidemiological knowledge. Studies aimed to clarify an evaluation of change of thermal environment based on psychological and physiological reaction for a posture of supine are needed. This report aims to exam an evaluation of change of thermal environment based on psychological and physiological reaction for hospitals. As a result, mean skin temperature for thermal neutralization became 33.7〜33.8℃ and for maximum thermal comfort became 34.1〜34.3℃ regardless of sex and cooling system almost equally to the value. Based on amount of physiological unit and psychological slope ratio, the radiant cooling system and convection cooling system has almost the same performance for hospitals.
