Calculate Mean Radiant Temperature & UTCI thermal comfort using the SOLWEIG model.
About
SOLWEIG (Solar and Longwave Environmental Irradiance Geometry) is a high-performance urban microclimate model for calculating Mean Radiant Temperature and thermal comfort indices. Features: - Single timestep and timeseries Tmrt calculations - UTCI (Universal Thermal Climate Index) computation - PET (Physiological Equivalent Temperature) computation - Sky View Factor (SVF) preprocessing - EPW & SUEWS weather file import - Support for large rasters via tiled processing and GPU Requirements: - The SOLWEIG Python library must be installed separately. - The plugin will offer to install it automatically on first use. - To install manually, run this in the QGIS Python Console: import pip; pip.main(["install", "solweig", "--no-deps"]) Documentation: https://umep-dev.github.io/solweig/ This plugin provides QGIS Processing algorithms that wrap the SOLWEIG Python library. This version of Solweig is currently in testing as a proof of concept for Rust + GPU + tiled processing to handle large rasters.
