Occupational Safety Systems Design and Maintenance Building says one of the sources of indoor air pollutants is HVAC and ensuring maintenance of them. “When the HVAC system is not functioning properly for any reason, the building is often placed under negative pressure. In such cases, there may be infiltration of outdoor pollutants such as particulates, vehicle exhaust, humid air, parking garage contaminants, etc. Also, when spaces are redesigned or renovated, the HVAC system may not be updated to accommodate the changes. For example, one floor of a building that housed computer services may be renovated for offices. The HVAC system would need to be modified for office employee occupancy (i.e., modifying temperature, relative humidity, and air flow).”
