- Abstract
- The U.S. Department of Housing and Urban Development's Healthy Homes Initiative is addressing a wide range of indoor air quality (IAQ) concerns to improve urban housing conditions and protect the health of children. To evaluate the impact of potential interventions on indoor contaminant concentrations and occupant exposures, a simulation study was conducted using the multi-zone IAQ model CONTAM. The model was used to predict ventilation rates, contaminant concentrations of carbon dioxide, carbon monoxide, nitrogen dioxide, water vapor, particles, radon, and volatile organic compounds and occupant exposures for a baseline case and for eight different interventions, which included source control, filtration, local exhaust ventilation and dilution ventilation. While source control interventions were always the most effective on an individual contaminant basis, not all sources of indoor contaminants can be removed. On the other hand, interventions impacting air change rates, such as ventilation and envelope tightening, can either increase or decrease contaminant concentrations depending on the origin of the contaminants.
