Abstract:

Daylight has a large impact on human health and well-being. Existing research thoroughly addresses visual comfort conditions and has begun to focus on circadian lighting as well. However, there is a gap in research on the intersection between circadian lighting and visual comfort. In order to gain a better understanding of the connection of these parameters of daylight, this study utilized computer-based daylight simulation to evaluate both the visual and circadian effects of daylight by simulating different window-to-wall ratios (WWR) in an office space. The results of the simulations show that there is an overlap in recommended daylight autonomy (sDA) and circadian lighting measurements between a WWR of 40%-90%.
