Energy conservation and indoor air pollution

Presents model of indoor pollution that assumes a linear relation between indoor pollutant levels and the air change rate. Discusses effect of heating system and cooking on pollutant levels and ventilation rate. The model predicts that when air change rate is reduced 4-fold, heating systems pollutant contributions can still rise up to 3-fold despite the saving in energy from reducing ventilation. Suggests precautions are necessary when tightening building envelope. Recommends that pilot lights be eliminated and effective kitchen ventilation systems installed.
