Indoor air quality simulation
Chambéry, AURA

In Chambéry, the teaching and research premises of the area have high and variable occupancy densities, a parameter that bears directly on the predicted concentrations and on the sizing of the ventilation. The valley setting, prone to winter thermal inversions, also makes the siting and filtration of air intakes more sensitive than on an open site. The simulation with INDALO makes it possible to test these scenarios at the design stage and to provide the justification required in the file. This is a modelling study, carried out ahead of works.

In Chambéry, 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.
