Free Grasshopper Definition: Ladybug Direct Sun Study (Ladybug Tools)
Original title: Ladybug sample: direct_sun_study.gh
Overview
direct_sun_study.gh is an official Ladybug sample definition from Ladybug Tools LLC, kept in the samples folder of the ladybug-grasshopper GitHub repository. The definition imports EPW weather data, builds a sun path and runs a direct-sun-hours study on building geometry, then displays the results with legend and graphics components, giving a compact template for solar and shading analysis in Grasshopper.
It requires Ladybug Tools 1.x (free via the Pollination installer or Food4Rhino) and is released under AGPL-3.0; the .gh is a free direct download from GitHub, alongside about 28 other samples such as radiation_study.gh, solar_envelope.gh and outdoor_comfort.gh. A good first environmental analysis file for architects.
