Heating system-generated indoor air pollution

Heating systems may emit pollutants into living spaces of buildings. Presents model for estimating exposure to pollutants allowing for variation of air change rate and inside-outside temperature differences. Examines the effect of energy conservation measures. Concludes that if ventilation alone is reduced the pollutant concentrations will rise but if reduced ventilation is balanced by increased insulation then pollutant contributions will remain unchanged. The analysis applies only to pollutants generated by the heating system.
