Abstract

Garages contain many harmful pollutants, including particulate matter smaller than 2.5 micrometers (PM2.5). These particles are responsible for millions of premature deaths annually, underscoring the urgency of mitigating air pollution. This study addresses the increase in air pollution in underground parking garages due to automobile exhaust. A physical model is used to demonstrate the effectiveness of auto-adjustable ventilation systems to clear PM2.5 pollutants in a one-level underground garage.  Results show the most effective setup for achieving optimal air clearance in the testing trials is operating a central exhaust along with intake fans at 50% capacity.
