The aim of the BASE study was to collect air quality data for office buildings in the USA, using air flow rates measurements or tracer gas (CO2) methods. Results for 100 buildings are summarized : 11 % of buildings have outside air ventilation rates below ASHRAE recommendations. The accuracy and the limitations of the measuring methods are also analyzed. CO2 tracer gas method best represents the ventilation rate.
