Energy conservation and indoor air pollution
AbstractEnergy-conservation measures for buildings work partly by reducing air exchange (v) between buildings and their surroundings, resulting in greater retention of pollutants emitted indoors by combustion and other sources. For example, if v is reduced 4-fold, pilot-light pollutant contribution will quadruple (perhaps rising from ≅5 mg/m3 to ≅20 mg/m3 for carbon-monoxide). A calculation shows that it might take h for CO levels to decline below the EPA one-hour ambient standard after only 1 h of oven use in a small kitchen when air change/h (ach) but less than h when v = 1 ach.We present a model that accounts for the reduced heating system operating requirement permitted by energy conservation by assuming that indoor pollutant levels are linear in v This model predicts that when v is reduced 4-fold, heating system pollutant contributions can still rise up to 3-fold, depending upon building characteristics and the extent of increased insulation.Thus precautions are clearly necessary when tightening building envelopes. At a minimum, pilot lights should be eliminated and effective kitchen ventilation systems installed.
