Summary
This paper presents a new simulation tool and workflow for modeling the non-image-forming effects of light, integrating inputs from all five retinal photoreceptors as processed by ipRGCs. Practical application enables lighting designers to predict and optimize circadian-effective light exposures during the building design phase, before physical installation.
Key Findings
- A workflow was developed to simulate non-image-forming light effects by combining spectral inputs from all five photoreceptor types (S-cones, M-cones, L-cones, rods, and melanopsin-containing ipRGCs).
- The tool enables computation of melanopic and other photoreceptor-weighted metrics within energy and building simulation environments, supporting circadian lighting design at the architectural planning stage.
Categories
The Science of Light: Directly addresses ipRGC photoreception, spectral sensitivity of all five photoreceptors, and simulation of non-image-forming (NIF) effects of light.
Sleep & Circadian Health: The simulation workflow targets circadian entrainment and other non-image-forming biological effects relevant to lighting design for health.
