Describes an assessment using carbon monoxide and volatile organic compounds as IAQ indicators for indoor air quality in a representative underground parking facility. Measurements were made at different time intervals throughout the day. The EMFAC7F1.1 model was used to estimate vehicular emission factors. Concentration profiles were then assembled using a transient mass balance model. Estimates were made of the ventilation rates required to maintain pollutant concentrations within acceptable standards under maximum UPF occupancy, and a sensitivity analysis was conducted to evaluate the effect of changes in EMFAC7F1.1 input parameters on EFs and ventilation rates.
