Research is currently being conducted at Stuttgart University of Applied Sciences to improve urban sustainability and resilience in the city of Stuttgart with the help of geoinformation systems (GIS) and microclimate simulations. Muhtasimul Islam Rushdi, under the direction of Prof. Dr Angela Blanco-Vogt, is investigating the impact of green spaces on the urban microclimate, with a focus on mitigating the Urban Heat Island (UHI) effect in Stuttgart's urban environment
In a recent study, the relationship between simulated microclimate data from the ENVI-met software and real measurements is analysed. The study, which was carried out at HFT Stuttgart, shows that the conversion of paved areas into green spaces can lead to significant temperature reductions that promote better thermal comfort and environmental sustainability. Specifically, based on simulations, temperature reductions of up to 1.15°C were observed in some areas, highlighting the potential for urban design strategies to combat climate challenges in the city.
The study showed a strong correlation between the simulated and actual temperature and humidity data, with R² values of up to 0.93 (= 93%, very high fit of the model to real measured data), confirming the reliability of ENVI-met as an important tool for analysing the urban microclimate. This emphasises HFT's commitment to using innovative technologies such as GIS to develop climate-conscious solutions that are both resilient and connected.
The following images illustrate the GIS analysis and the changes in the microclimate variables (temperature and relative humidity) due to changes in the proportion of green space. One image shows the green area added in each case. The other image shows the effect on the air temperature (in °C, blue/green areas = decrease in temperature).
This work supports HFT Stuttgart's strategic vision of being climate-competent - resilient - connected and demonstrates how geographic information systems (GIS) and simulation technologies can drive sustainable and adaptive urban design. It is a testament to the university's commitment to applied research that contributes directly to climate-conscious urban planning in Stuttgart and beyond.
At HFT Stuttgart, we are not only researching the future - we are also shaping it.
