Sources of indoor contaminants.

Characterizes indoor contaminants as two continua - mass stressors and energy stressors. Describes the rates of generation and transportation of contaminants in terms of 4 sources (outdoor air, building materials, occupants and indoor processes) in 4 environmental zones. Reviews information on contaminant generation and discusses factors that affect these rates, including temperature, moisture content, acidity, room air distribution and occupant proximity. Concludes that sufficient information is available for new control strategies to be used to provide acceptable indoor air quality.
