Achieving good IAQ in polluted surroundings

BRE has developed guidance to help architects and designers achieve acceptable indoor air quality in areas with high pollution levels, whilst providing sufficient ventilation for the building. Existing guidelines on ventilation requirements usually assume that the external air supply is ‘fresh’ and free from contaminants, which is often not so in urban areas.

This report, funded by BRE Trust, provides practical information on how to assess the concentration of pollutants in the vicinity of proposed urban buildings or developments from a range of sources. It also looks at ways to reduce the impact of polluted outdoor air on indoor environments.
