Conservation measures that seal a building, like storm window installation, can significantly reduce its energy requirements. These measures also protect its occupants from air pollutants having outdoor sources but amplify any harmful effects of those generated indoors. Using these Fourier series techniques and an approximation of outdoor pollution peaks by step functions, we obtained the following results: the average daily concentration indoors is the same as outdoors for any pollutant with no indoor sinks if inside and outside air are assumed uniform (that is, well mixed). However, lowering a building's air exchange rate 4-fold will still protect its occupants from outdoor pollution sources, but only if the outdoor peak or variation above its average is much greater than its average, and the peak is short-lived.
