3. Calculating natural ventilation
In order to obtain a façade pressure coefficient for each wind event over the year, a computational fluid dynamics (CFD) calculation is performed for several angles of incidence.
The approach used conventionally, as well as that adopted in this article, is then presented. The influence of the wind rose, angular discretization and the presence of the urban environment on the estimation of natural ventilation is also discussed.
3.1 Case study presentation
A calculation was carried out for the Strasbourg station, where the hall is largely glazed, making it highly susceptible to infiltration. Its access doors are also frequently open during the day. The meteorological file used takes into account conditions representative of Strasbourg's...
