Discomfort glare is caused by a light source sufficiently bright to cause annoyance, discomfort, or loss in visual performance. Both absolute brightness and apparent brightness produce discomfort glare. And the severity of the glare that a light source causes is due largely to its brightness. The Purpose of his study is to evaluate discomfort glare sensation difference from distance on the non-uniform window plane. The experiment was conducted at 1.5m and 3m distance from the glare source. Three results were obtained from the experiment. First, the discomfort glare degree was increased according to luminance of lighting source was increased. Second, the distance of the subjects did not have relative with the discomfort glare rating. Third, distance was increased 1.5m to 3m, the result of DGI and luminance values which were decreased. |
