Research Abstract

To assess discomfort glare from daylight, dynamic evaluation method is required. The purpose of this study is to develop an evaluation method for discomfort glare from windows including shading devices. Glare sources are determined from the visual field by using luminance image and the effect of adaptation level on glare sensation was examined. The border between the contrast glare and the saturation glare was determined due to the change of the pupil size and the effect of spectral distribution on peripheral glare was tested. The applicability of the evaluation method was also demonstrated.
