L'hypercube is proud to have contributed to the Grand Prix National de l'Ingénierie 2021, won by AREP teams, for the transformation project of the Saint-Michel Notre-Dame station (RER C).
For the hypercube, it is the recognition of the Air Quality expertise, born during this project in 2017.
After preliminary study phases that were marked by the development of predictive models of air quality in train stations and a fruitful collaboration with the CSTB allowed us to develop a simulation framework to estimate the ventilation induced by train passages ("piston" effect),the main driving force of the air quality improvement on this project.
Subsequently, we had to deal with other site constraints, such as acoustics and flood control. It is precisely this collective and iterative work of the different engineering departments that was rewarded by the GPNI!
Below is a video presentation of the main challenges of the project:
