Big city life is vibrant. Many people, however, means reduced quality of air. The Planning Advice Map Urban Climate (PHK), which was developed in 2001, aims at improving the climate.
The PHK comprises results of extensive urban climate modelling. The key focus of the PHK is the thermal situation, i.e. thermal load, in the city. More than 60 percent of the city area have been classified as “unfavourable” or “less favourable” in that regard. This means that our natural air con is letting us down in these areas. Updrafts would normally pull the heated air higher up, which would then be replaced with cooler air from green spaces.
Climatic concerns can be integrated adequately into urban development planning based on the PHK. In its latest 2022 version, it consists of an assessment of daytime conditions, nighttime conditions, and a combined overall assessment; a map identifying areas with particularly poor urban climate conditions and vulnerable areas; and a map of recommended measures.
