Indoor air quality measurements in energy-efficient houses.

Reports field monitoring program by the Lawrence Berkeley Laboratory to assess the potential impact of reduced ventilation of indoor air quality. Three houses, designed to be energy-efficient, were monitored using a mobile laboratory. Parameters measured included infiltration rate, CO2, CO, NO2, NO, O3, SO2, HCNO, total aldehydes and particulates. Preliminary results show that although considerable energy savings can be achieved, indoor levels of several pollutants exceed levels found outdoors; however in general, the indoor levels of most pollutants are still within limits established by ambient air quality standards.
