Abstract: This paper describes experience gained attempting to evaluate visual comfort in a brightly lit workspace. Simulation demonstrated that common discomfort glare metrics such as Daylight Glare Probability (DGP) and Daylight Glare Index (DGI) were ineffective for evaluating glare in a brightly illuminated space, and a subsequent mockup confirmed this conclusion. We attempt to explain why the metrics produced unsuitable simulation results.
