The Lawrence Berkeley National Laboratory Population Impact Assessment Modeling Framework (PIAMF) was expanded here to enable determination of indoor PM2.5 concentrations and exposures in a set of 50,000 homes representing the US housing stock. A mass-balance model is used to calculate time-dependent pollutant concentrations within each home. The model includes size- and species-dependent removal mechanisms. The particle model was applied to the housing samples of the Relationship of Indoor, Outdoor, and Personal Air (RIOPA) and The Detroit Exposure and Aerosol Research Study (DEARS) studies to compare model- and measurement-based estimates of indoor PM2.5 of outdoor origin. Model-derived distributions of infiltration factors (ratio of indoor PM2.5 of outdoor origin to outdoor PM2.5) are compared to measurement-based distributions obtained in studies conducted in 11 US cities.
