New climate zone model with arbitrary shape and stratification

Included in the Expert edition

A new zone model for detailed indoor climate analysis with results visualized in a 2D/3D-grid of the zone volume (air temperature, air velocity, operative temperature, draught risk, CO2, PPD, PMV).

The new model supports:

Points

Detailed radiation for arbitrary room geometry (also non-convex) with detailed view factor calculation, for long-wave and diffuse solar radiation exchange between surfaces and between surfaces and occupants.
Air stratification based on flow elements such as jets, plumes, and wall currents, e.g. cold air draft close to window in winter.
Operative temperature with, optionally, direct and diffuse short-wave radiation taken into account.
Equipment and other loads with position in the zone.
Position dependent sensors.
