Natural ventilation is at the heart of the bioclimatic strategy implemented on the future extension of the Roland-Garros airport on the Réunion Island. The project's morphology, characterised by the presence of a central climatic canyon, uses wind-related pressure gradients to renew the air, without having to pay for a ventilation system. From the onset, the validation of the concept represented a major challenge because reaching sufficient air renewal and flow control is crucial to the proper functioning of the terminal building.
The AIA Environnement team entrusted the CSTB with a series of tests at the Jules Verne wind tunnel in Nantes, which took place last September from the fourth to the nineteenth. A 1:150 model of the terminal building was specifically made.
