| Abstract |
Discomfort glare from a real daylight window is appraised to examine the effect of the average luminance of the window on discomfort glare. The window is divided into 6 parts. Discomfort glare from each part of the window and from the whole window is evaluated by 32 subjects. The degree of discomfort glare is an increasing linear function of luminance of each part, but the average luminance of the whole window is not related to the degree of discomfort glare. It is concluded that the average luminance of the entire window is unlikely to be a factor in the genesis of discomfort glare. |
