Abstract

Mass-balance models for indoor concentrations of CO, NO and NO2 were applied to an energy-efficient townhouse. Model parameters included source emission rates, infiltrating airflows, and, for NO2, loss rate coefficients. Emission factors for CO, NO and NO2 were estimated for each of the gas-fired appliances in the house. Airflows were estimated using sulfur hexafluoride (SF6) decay techniques. Loss rates for NO2 were calculated as the difference between NO2 removal rates and estimated air exchange rates; CO and NO concentrations decayed at a rate not significantly different than that for SF6. Comparing model predictions with measured concentrations yielded differences averaging 17% for CO and NO, and 28% for NO2.
