Urban densification influences wind, temperature, noise, daylight and air quality in both city scales and microscales like streets, neighbourhoods, parks. While software for wind simulation is available and best-practise guidelines have been formulated throughout the years, this is not the case for the simulation of heat. As climate change poses significant challenges on the built environment e.g. in form of heat waves and heavy storms, a resilient and liveable city can only be developed when the abovementioned environmental aspects are considered throughout the planning process.
