The indoor air quality in an air conditioned California high school has been measured over a range of ventilation rates ranging from 13.3 ft/sup 3/ of outside air per minute for each classroom occupant to approximately 1.5 cfm per occupant. The purpose of this pilot study is to determine the effect of reduced ventilation on indoor air quality and energy use. Parameters measured include outside air supply rate, occupants' subjective perception of indoor air quality, microbial burden and the concentrations of carbon dioxide, carbon monoxide, nitrogen oxides, sulfur dioxide, and ozone in two classrooms, a hall, and outdoors. Results show that carbon dioxide was the only parameter to show a substantial increase in indoor concentration when ventilation rates were reduced; however, classroom levels of carbon dioxide still remained far below levels considered to be a health hazard. This study indicates that at Carondelet High School, moderate energy savings are possible without significant deterioration of indoor air quality, and that substantial energy savings would be possible in a more severe climatic region.
