Abstract: Existing discomfort glare metrics have been utilized to evaluate various daylit scenes. However, existing metrics focus on reporting perceived levels of discomfort glare without identifying what causes the problem. This paper develops a new analysis method, which can inform users both the existence of discomfort glare and its dominant cause in a daylit space. Human subject study was performed inside a closed office. More than 150 glare scenes were collected with subjective evaluation surveys. The collected data was statistically analyzed to develop a new method using luminance and contrast ratio, which will help promote discomfort glare analysis in daylighting design.
