Category: infrastructure

Tags: radiosity, lighting-simulation, webgpu

Score: 6.7/10 (Innovation: 6, Technical: 7, Documentation: 5, Utility: 7)

CircadianLab is a browser-based radiosity lighting simulator that calculates mel-EDI, illuminance, glare, and daylight metrics using WebGPU. It stands out by combining practical lighting engineering standards (ANSI/IES RP-46-25, CIE S 026) with an accessible web tool, potentially filling a gap for architects and lighting designers who need rapid circadian-light analysis without heavy desktop software.

Target audience: architects, lighting designers, building engineers
