Abstract

ABSTRACT LEED is one of the most widely adopted building benchmarks globally, and it encompasses multiple rating criteria for performance. However, such criteria typically focus on reducing energy consumption and may disregard providing a high level of occupant satisfaction. LEED focuses on a desk height evaluation of Spatial Daylight Autonomy and Annual Sunlight Exposure to predict the daylight availability and probability of glare, respectively, which may disregard an occupant’s visual comfort at eye level. This paper proposes a more comprehensive approach to daylighting performance evaluation in a commercial office space that incorporates Annual Glare – vertical-eye level glare evaluation, in addition to Spatial Daylight Autonomy and Annual Sunlight Exposure. A comparison between Annual Sunlight Exposure and Annual Glare is established to understand the criteria missing in LEED that evaluates discomfort glare and improves the visual performance and comfort of the occupants significantly.
