Abstract The position of air intakes on the roof of a building is a determining factor for indoor air quality owing to the possible reintroduction of contamination from the neighbouring exhaust stacks. Ventilation system designers currently use tools such as mathematical models and wind tunnel simulations to estimate the dilution between the source and the air intake. Using field tests and boundary layer wind tunnel modelling, this study investigated the dilution phenomenon and impact of certain parameters (wind direction, stack height and location, roof irregularities, turbulence, air exhaust velocity) to refine the models used. This project resulted in the development of guidelines intended for ventilation engineers. The results are also of interest to professional associations and standardization organizations.
