Summary
This paper presents a novel 3D rendering framework that simulates all five photoreceptor-channel illuminances (not just melanopic lux) to predict circadian exposure during the building design phase. Lighting designers and architects can use this tool to evaluate how daylight availability, room geometry, and surface materials collectively shape occupants' circadian stimulation before construction.
Key Findings
- Extends circadian simulation beyond melanopic illuminance to include rhodopic, cyanopic, chloropic, and erythropic lux, enabling a more complete picture of photoreceptor activation.
- Demonstrates that daylight strategies, spatial configurations, and material reflectance choices each independently alter the contribution of the five photoreceptor channels to circadian regulation.
- Establishes a novel multi-dimensional rendering pipeline intended to support both future circadian research and practical applied lighting design solutions.
