Summary: This information paper focuses on use of Pollutant Ingress Index to develop more effective ventilation of buildings. Effective ventilation of buildings to provide optimum indoor air quality relies on good outdoor air quality in the locality of the building. However, in practice, outdoor air is often contaminated by pollutants from external sources. A new methodology giving a Pollutant Ingress Index has been developed to identify the areas of a building where pollutant ingress is most likely to occur and to determine the relative magnitude of this ingress. Application of the methodology will assist with optimum placement of building ventilation inlets, carrying out more effective air quality assessments in relation to indoor air quality, and developing strategies to protect building occupants from toxic contaminants releases.
