Planning measures for the mitigation of local human heat stress:
Local heat stress, which is caused by the combined effect of changed atmospheric background conditions due to regional climate change and the dynamics in the urban development, is a burden especially for people in urban quarters, which were less confronted with it in the past, such as in Central European cities.
Due to its negative impacts on the increasing urban population, urban planning is faced by the challenge to design measures for the reduction of local human heat stress within urban quarters. For this, suitable results from numerous human-biometeorological investigations are available, which quantify the qualitatively long-known impacts of such planning measures by thermo-physiological assessment indices.
For Central European inland cities, a dual planning strategy represents an effective measure for the mitigation of local human heat stress. It is based on the reduction of the daytime heat input into all urban spaces, especially through the shading of the direct solar radiation by green infrastructure, and sufficient ventilation. This dual strategy is easier to implement in new planning than in urban renewal in already existing urban quarters.
