This paper describes the measured and calculated results of air infiltration and decay profiles of tracer gas in a passive solar test house used to evaluate the simulation model COMIS for multizone air infiltration and pollutant transport. The interior leakage and exterior windows and wall leakage were measured by the fan pressurization method. Air infiltration was measured in three rooms under different conditions. The concentration decay method using three gases, N2O, SF6, and CHCl2F, was employed to find the air exchange rates and investigate indoor pollutant transport. The data, such as gas concentrations, temperatures, and wind, were measured in situ. In addition, the data from the measurements were used as simulation input data for air infiltration and pollutant concentrations, assuming tracer gases as the pollutant. The results of comparisons between measurement and simulation values of air exchange rates and tracer gas concentrations using the COMIS model are reasonable.
