References(1) The effects of the glare level and the illuminance level on visual comfort and discomfort experienced by the observers were investigated in a full scale office room located in the laboratory. Sixty-one observers, who were not informed of the real aim of the observations, aged from 20 to 41, were asked to rate their impressions as to various lighting conditions in the room on the Semantic Differential Rating Scales consisting of 13 pairs of adjectives. As a result, the influences of the glare and the illuminance level on which adjectives were chosen by the observers were analyzed statistically. We found that the illuminance had a greater influence on the comfort of the interior atmosphere than did the luminance of the luminaires. Also, the luminance had greater influence on the psychological tenseness of the interior atmosphere than on the comfort of the interior.
