Perception of glare in relation to the CIE scale on Unified Glare Rating (UGR) and the impact of ambient light on both UGR and Subjective Glare Index Scales (SGI)
(2023) The 30th Quadrennial Session of the CIE- Abstract
- Today the UGR tabular method according to CIE 117-195 and CIE 190-210, is practically the only one used for evaluation of glare in the lighting design process. It is important to investigate if the method is in line with the subjective perception of glare (SGI). The objective of the study was to investigate whether the perceived discomfort glare from commonly used lighting systems for workplaces is in agreement with the UGR calculation method currently used in lighting design to estimate the degree of discomfort glare. We have compared four different SGI with UGR in order to see how well they correlate. Another objective with the study was to investigate how important the room brightness is for the experience of discomfort glare.... (More)

Today the impact of ambient light is normally not considered in the calculation of discomfort glare when using the UGR tabular method. (Less)
