Research conducted by the TU/e revealed that the effect on air quality in the city center of Eindhoven could be substantial when fine dust and soot is captured in underground car parks and clean air is released back into the city. The researchers used computer simulations and models to demonstrate that the potential improvement of city air extends well beyond the immediate areas.

Feasibility study

In the first phase of the project, TU/e has investigated the potential of purifying the city air by implementing ENS Urban air purification systems in parking garages in the city center of Eindhoven. The effect on air quality was analyzed using three-dimensional computer simulations (Computational Fluid Dynamics, CFD).

Under the direction of Professor Bert Blocken (Research Group Urban Physics and Wind Engineering), the buildings in the city center of Eindhoven were mapped out in great detail. 16 underground parking garages were included, to allow the analysis of the effect of the reduction of particulate matter in these parking garages on the concentration of particulate matter and soot in the city. Two scenarios were analyzed: one minimum scenario with 99 and one maximum scenario with 594 air purification systems.

Validation measurements

During the second phase, highly detailed measurements were carried out around one parking garage to validate the calculation method on which the simulation models are based. Data analysis is currently being finalized, after which the results from the first phase are being refined and re-analyzed.

The result is insight into the relationship between the required cleaning capacity and the extent to which city air quality can be improved. The results will be presented mid-2020 in a scientific peer-reviewed journal.

Practical cases and measurements

In recent years, many impact studies have also been conducted in practical projects such as parking garages, tunnels, street canyons and public buildings.

With air flow simulations, an optimal placement was investigated prior to the application, after which measurements were used to compare the situation before and after placement. This always showed that it is quite possible to significantly improve the air quality at these locations, creating a healthier stay for visitors and staff. Such impact studies are carried out with external measuring institutes.
