사무실 공간의 조명환경 변화에 따른 시각적 감지 변화

Abstract

This study examines the influence of color temperature and illuminance levels on occupants' visual perceptionin a small office space. Field measurements and surveys were conducted in a full-scale mock-up space wherefour lighting conditions were formed by direct/indirect lighting fixtures. Results imply that the perception of glareincreased as color temperature of light increased. Under equal color temperature conditions, the increase of illuminancecaused more glare. The glare perception for paper tasks was weaker than that of computer tasks. Subjects felt thatspace became more spacious as color temperature increased under equal illuminance levels. In order to enhance visualcomfort under 3500K conditions, the space should be kept bright and lighting environment needs to be maintained ina way that occupants see letters clearly. Under 5000K conditions, the perception of visually warm and brightness isan influential factor on visual comfort.
