This plugin has an experimental version available!
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"])
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.
