Main Components

MRT Sensors
Create comfort sensor probes from a mesh (face centers) or points.
MRT Surface
Mesh Breps into a tagged radiation surface for an MRT analysis.
Surface Settings
Thermal + optical material properties for a building/ground MRT surface.
Thermal Comfort
Compute a thermal comfort metric at a point: UTCI (Ta, RH, wind, MRT), PET (adds the personal inputs), or NOAA Heat Index (Ta, RH only). Pick the metric from the dropdown — the inputs adapt. Wire hourly lists (e.g. EPW series) to compute annual values.
Tree Settings
Canopy material properties for an MRT tree surface.
Vegetation Settings
Leaf/canopy material properties for an MRT vegetation surface.
MRT
Compute mean radiant temperature at the sensors. Direct-raycast shortwave by default; wire MRT Settings with reflections/diffuse radiation on to use the Radiance DDS engine.
MRT Settings
Configuration for the MRT + UTCI analysis.
Sky Exposure
Computes the Sky View Factor (SVF) for each input point using the Tregenza 145-patch sky subdivision. Casts 145 rays toward the upper hemisphere and returns the fraction of unobstructed sky directions (0 = fully obstructed, 1 = fully open sky).
UTCI Simulation
Compute annual per-probe UTCI from simulation outputs: MRT and wind-speed data trees, plus air temperature and relative humidity. For a weather-only calculator, use "UTCI (Weather)".
