In this paper, a CFD analysis of airflow and contaminant distribution within enclosed vehicular parking facilities is presented. First, the CFD simulation is validated using field data. Then, the results of a parametric CFD analysis are summarized. In particular, it was found that significant fan
energy savings can be obtained when simple on-off controls are properly implemented without affecting the indoor air quality within the garage. Moreover, it was found that the position
of the exhaust fans relative to the supply fans can be crucial to ensure high effectiveness of the ventilation system.
