Synopsis

Whole-building airflow and contaminant transport modeling has a potentially important role in the development of contaminant sampling strategies in response to the airborne release ofchemical or biological agents . The effectiveness of these strategies relies on the ability of theselected sampling locations to adequately characterize the levels of contamination throughoutan exposed facility to a desired level of confidence in the sampled results. The Department ofHomeland Security has sponsored a series of multi-agency exercises, during which contamination experiments were performed to gauge the confidence that could be obtained by various sampling strategies as well as the effectiveness of various sampling methods in a real-worldsetting. These experiments are very resource intensive and time-consuming, limiting thenumber of experiments that can be reasonably performed. Building simulation can be used toperform virtual experiments that would allow more tests to be performed under a much larger set of building operational and environmental configurations. However, in order for thesimulations to be useful, the building models need to provide realistic results with a high levelof confidence. The purpose of this report is to describe a simulation validation effort based onmeasurements of contaminant levels performed during the aforementioned exercises.
