Indoor air quality is important to human health because people spend significant amount of time indoors (Klepeis et al., 2001). In addition to provide adequate air exchange for the indoor environment, air-conditioning and mechanical ventilation (ACMV) system in office building also helps to protect indoor occupants from exposing to air pollutants originated from both indoor and outdoor sources. This study aims to understand the level of protection provided by the ACMV system during both hazy and clear outdoor conditions. The indoor and outdoor particle concentrations were monitored simultaneously to evaluate the impacts from the ACMV system.
