Description:
The chapter discussses indoor air quality (IAQ) modeling. Such modeling provides a way to investigate many IAQ problems without the expense of large field experiments. Where experiments are planned, IAQ models can be used to help design experiments by providing information on expected pollutants. IAQ models can also provide information on the factors that are important and help in determining what must be measured. Mass balance models provide the tools best suited for studying general IAQ probelms. These models can provide good predictions of pollutant concentrations and individual exposure under a wide range of conditions. The models allow rapid analysis of IAQ control options. Where information on population exposure is desired, statistical models are useful. And where information on personal exposure very near sour ces is desired, computation fluid dynamics models are required. The quality of the model predictions depends on the adequacy of the input data. The most important data are those necessary to describe source and sink behavior. Source and sink data are not available for many important indoor sources. Where the data are available, they are not adequate to provide a detailed description of the variability of the pollutant emissions.
