Overview
annual_daylight.gh is an official Honeybee Radiance sample from Ladybug Tools LLC in the honeybee-grasshopper-radiance GitHub repository. The definition sets up sensor grids and a sky matrix from EPW weather data, runs the annual daylight recipe with the Radiance engine and visualizes metrics such as Daylight Autonomy and UDI on the model.
It requires Ladybug Tools 1.x with Honeybee Radiance and the free Radiance engine, is licensed AGPL-3.0, and downloads directly from GitHub; the same folder holds 18 samples including daylight_factor.gh, annual_glare.gh, leed_i.gh and en17037.gh. A practical starting file for daylighting studies and LEED or EN 17037 style reporting.
