Simulate non-visual lighting in Grasshopper

New version of Lark Spectral Lighting Grasshopper plugin

Why is this relevant?

Our eyes have a dual function: They allow us to see, but they also mediate several psychological and physiological (non-visual) responses. Light reaching the eyes regulates circadian rhythms and affects alertness. Since we spend most of our time indoors, building designers are responsible for providing healthy indoor lighting. A simulation tool is now available to help meet this challenge.

New version of the Lark simulation tool

Lark Spectral Lighting 2.0 is available on food4Rhino with new features, components, and templates to investigate non-visual lighting design. Lark is a plugin that helps architects, designers, and researchers examine a lighting design's effect on circadian rhythm and alertness.

The updates in Lark 2.0 include:
  • Ability to run daylight and electric light simulation
  • Calculation of spectral irradiance and output metrics relevant to the non-visual effects of light according to the CIE (α-opic metrics)
  • Analysis workflow that accounts for the direction in which light reaches the human eye, which is relevant for non-visual effects
  • Simulation of a period of light exposure and analysis to optimize alertness according to a light-driven biological model
