Single Tracer Gas Decay Measurements

Attached garages can pose a threat to a home’s indoor air quality because the garage air, which often contains some contaminants such as particulate matter, carbon monoxide, and volatile organic compounds, can migrate into living spaces. In this paper, a model is developed to characterize the transport of contaminants from a garage to a living space based on a measurement of single tracer gas decays without limiting the numbers of zones in the building.
