Indoor air quality simulation
Perpignan, Occitania

In Perpignan, the housing schemes and public facilities likely to pursue certification are designed in a hot and windy climate, where the siting of air intakes and the sweep principle call for particular attention, in particular with regard to outdoor sources and exposure to the tramontane. The simulation with INDALO models the predicted concentrations from the emissions of the specified products, the ventilation system and the occupancy scenarios, and produces the justification expected in the file. This is a study carried out at the design stage, with no air sampling or analysis.

In Perpignan, the indoor air quality of a new building is decided at the design stage, through two levers: the specification of products according to their emissions health labelling and the design of the ventilation. The simulation estimates the predicted concentrations and produces the technical justification expected by certification schemes, before choices are locked in.
