This is version 1.0 release of Lark Spectral Lighting for Grasshopper to investigate circadian light metrics within a Radiance daylighting workflow. Lark includes tools to interpolate spectral data, build spectral materials, prepare spectral sky definitions and Radiance and DAYSIM methods to evaluate circadian illuminance and luminance. Lark does not include electric lighting nor should it be used with scenes that have direct beam light (yet).
