Indoor Air Quality

UNC Charlotte indoor air quality (IAQ) refers to air quality inside university buildings. These buildings have natural ventilation or mechanical heating, ventilation, and air-conditioning (HVAC) systems. The air quality in laboratories, classrooms and offices may contain sources of air contaminants: chemicals, fumes, and particulates. Common causes of air quality concerns include HVAC system failures, mold, inadequate air supply, and odors.

what you need to know

  • If your work activities create odors, take action to reduce or eliminate exposure. This may consist of the following:
    • Using “green” or low emission (low VOC) paint, carpet, or furniture.
    • Opening a window, turning on a fan or local exhaust ventilation.
    • Performing the activity outdoors.
    • Scheduling work when the building is minimally occupied.
    • Adjusting work schedules if the building indoor temperature reaches excessive levels.
    • Not allowing gas powered vehicles to idle near building air intakes.
    • Disposing of all foul odor foods and ensuring sink drains are regularly flushed.
  • If you notice an odor, check with building occupants to determine if the problem is throughout the building or specific location.
