居住者の温冷感覚におよぼす温熱環境と色彩環境の複合効果に関する研究

Abstract

It is very important to design and control the optimal indoor environment suitable for man's health, comfort and work-performance, taking into account as well the energy conservasion. The authors have proposed the need of the synthesized index covering thermal and non-thermal environmental factors for that purpose. In the present paper, the interactions between thermal event and color event, which is one of the representative non-thermal environmental factors, are discussed through four experiments using a chamber with red and blue walls for various room temperatures. There, the psychological responses such as thermal sensation, comfort level, and hue-heat impression of surrounding colors were measured by means of adjective pairs. Mean skin temperature were calculated for the physiological response. The main results are as follows : The interactions between thermal sensation and hue-heat impression was confirmed, taking into account affective reactions to thermal and color events. One is that hue-heat impression to color is significantly proportional to room temperature. The other is that thermal sensation was significantly affected by surrounding color in mainly such cases as room temperatures were changing from thermally uncomfortable condition to neutral condition and as the successive period after the change. In other words, so-called hue-heat hypothesis was confirmed. It is concluded that these interactions between different modalities are based on the intensity and/or the change of affection level aroused by each event.
