This project reviewed existing technologies that could protect the supply air systems of buildings from chemicalbiological chembio contaminants. This CH2M Hill research 1 analyzed existing filtration technologies for building heating, ventilating, and air-conditioning HVAC systems, and 2 examined numerical models for predicting air flows in and around buildings during a release of chemical or biological agents. This report gives the results of the research into numerical models. Researchers identified modeling products that would depict the results of a chembio release, and rated the models on resolution, cost, convenience, and accuracy. Four models were examined in depth, two for external and two for internal releases. The results provide a modeling approach that can be used to simulate the dispersion of contaminants inside buildings. Such a numerical simulation will help designers and managers evaluate possible ways to reduce occupant exposures to chembio contaminants.
