Heat analyses for outdoor spaces enable an early, quantitative assessment of thermal comfort. Based on a BIM model, simulations are carried out that calculate, among other parameters, the Physiologically Equivalent Temperature Index (PET), wind flows, and shading conditions. In addition, analyses according to UN climate scenarios can be incorporated to ensure long-term climate resilience in planning. The results are continuously integrated into the planning process and support data-driven, climate-adaptive design of outdoor spaces.
