This is the first 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. Note, Lark does not include electric lighting nor should it be used with scenes that have direct beam light (yet).

Lark Spectral Lighting is a collaboration of University of Washington and ZGF Architects LLP. We have tested this project, but it is the first release and it might still contain bugs. Please use it "as is", it does not come with warranties. We spent a lot of time developing the logic and implementing it, please give credit where credit is due.
