The attribution of pollutant concentrations on buildings from local traffic - Effects on ventilation requirements - A Wind Tunnel Modelling Study

This paper describes an analysis using the BRE Pollution Dispersion Wind Tunnel to estimate pollution concentration patterns on buildings in urban arrays due to local line sources of pollution, typical of vehicular traffic emissions. The experimental procedure involved measurements of both pressure and concentration patterns on building forms in urban arrays, intended to provide information on the ingestion of pollutants into buildings in urban areas.

Transport of contaminated gas and dust in high-rise apartment buildings.

Jacques Whitford Environment Limited (JWEL) and Morrison Hershfield Limited (MH) have completed a research project investigating the level of risk associated with soil gases and dust in high-rise apartment buildings. The research was conducted in response to a request for proposals issued by the Canada Mortgage Housing Corporation (CMHC). The study investigated the hypothesis that the risk associated with gas and dust from contaminated lands can be reduced for residents of high-rise apartment buildings compared to residents of single-unit or low-rise residential structures .
