| Abstract |
The purpose of this study was to evaluate and predict the discomfort glare on a window in the CIE standard overcast sky. For this research, a computer software program was developed to simulate DGI and UGR glare evaluations, and results provided by these glare evaluation system were analyzed for a variety of window conditions such as window-wall ratios, observer's positions, and window shapes. To verify the computer program, Superlite 2.1 and Radiance were used in this study. The results show that the keys to control window glare are as follows ; in a room shape, a small size cell-type room rather than a wide open-plan one is desirable; in wall-window ratio, below 60% window ratio is appropriate. |
