Abstract: The effects of building design on human circadian rhythms have been linked to health, behavior, and performance outcomes. Limited options, however, are available for predicting circadian stimuli during the design process, other than via quantification of a single variable known as melanopic illuminance. Several additional circadian illuminance quantities (including rhodopic-, cyanopic-, chloropic-, and erythropic-lux) have not, to date, been utilized in simulating circadian exposure. We demonstrate how daylight, spatial, and material choices may alter the contribution of five currently-known photoreceptor channels to regulating circadian rhythms. This novel 3D rendering system will also support future circadian research and applied solutions.
