Summary
This paper presents an extension to the open-source Lark simulation tool (plugin for Grasshopper/Rhino) that enables designers to model ipRGC-influenced light responses during the building design phase, incorporating spectral, temporal, and spatial lighting characteristics. Practically, this gives architects and lighting designers a computational workflow to evaluate and optimize circadian and alertness-relevant lighting conditions before construction.
Key Findings
- The Lark extension incorporates currently available knowledge on ipRGC-influenced light (IIL) responses including spectral sensitivity, temporal dynamics, and spatial distribution of light
- The tool is open-access and integrates as a plugin to Grasshopper for Rhino, demonstrated via a simulation workflow for building and lighting design
- No quantitative experimental findings reported; paper is a methodological/tool development contribution
