This paper presents an indoor air quality (IAQ) assess ment in a representative underground parking facility (UPF) using carbon monoxide and volatile organic com pounds as IAQ indicators. For this purpose, concentra tions of both pollutants were measured at different time intervals throughout the day. Vehicular emission factors (EFs) were estimated using the EMFAC7F1.1 model. A transient mass balance model was then applied to con struct concentration profiles. The ventilation rates re quired to maintain pollutant concentrations within ac ceptable standards were estimated under maximum UPF occupancy, and a sensitivity analysis was con ducted to evaluate the effect of changes in EMFAC7F1.1 input parameters on EFs and ventilation rates.
