Feasibility of Multi-Zone Simulation for Estimating Contributions of Outdoor Particulate Pollution to Indoor Particulate Matter Concentration

As concerns about the health effects of particulate matter (PM) are growing, controlling indoor PM has become vital for ensuring occupants’ health. Active strategies, such as air purification and high-performance filtering, widely implemented to control PM. However, passive including air-tightness compartmentalization, promising alternatives, demonstrated by recent studies. To enhance implementation an appropriate evaluation method designs must be established. The objective this study was investigate whether a multi-zone-based is suitable strategies. Multi-zone simulations were performed four seasons, indoor/outdoor concentration (I/O) ratios obtained exterior, interior, corridor on every floor reference building. I/O at different locations indicated that outdoor particle transport in building accurately estimated according airflow rate path. Moreover, addition changes temperature through envelope, size significant factor affecting concentrations. results multi-zone can effectively estimate number particles penetrate envelope seasons locations.
