Abstract: This paper builds on previous efforts to evaluate and compare dynamic light-exposure profiles over time and throughout space. This paper examines two office-floor plans through the eye-level exposure of 10 representative occupant profiles as they move throughout a series of seated locations over time. These 10 profiles are then used to create a weighted score for the full occupant population by applying the performance of each representative profile by the number of similar profiles in that same class. This allows us to compare the percentage of occupants that are expected to meet the WELL v2 Feature L03 150 EML target at a building scale, while also accounting for typical use patterns and pushing the WELL standard to account for dynamic behavior. The findings presented in this paper are meant to illustrate the impact of building form, interior material, and typical occupancy scenarios on circadian light exposure across a dynamic occupant population.
