This paper explores and elucidates two viable methods for conducting daylight simulations that verify whether a design achieves effective implementation of circadian daylight per the WELL Building Standard. The purpose is to weigh the relative efficacy of each of these emerging analysis methods, as well as their relative merits in interaction with other daylighting metrics.

The proposed circadian daylight analysis methods easily integrate into the design process to assess circadian daylight potential, but do not holistically address the full range of daylighting concerns in a project. Circadian daylight simulation should be used early in the design process, but must be coupled with traditional daylight analysis to evaluate illuminance levels and glare potential throughout the year.
