Building Ventilation

05/11/2008

Building ventilation is the circulation of air throughout a building. The ventilation or the heating, ventilating, and air-conditioning (HVAC) system of a building supplies and removes air either naturally (windows) and/or mechanically to and from a space. Building ventilation may be an important factor determining the relationship between airborne transmission of respiratory infections and the health and productivity of workers. Improper operation and maintenance of HVAC systems is one of the most common problems that impact workplace indoor environmental quality (IEQ).

There are a variety of pollutants and sources of pollutants in a building such as:

• carbon dioxide (CO2)
• tobacco smoke
• molds and bacteria
• cleaning products
• copy machines
• pesticides
• vehicle exhaust

Diligent maintenance of HVAC system equipment is essential for the adequate delivery and quality of building air. All well-run buildings have preventive maintenance programs that help ensure the proper functioning of HVAC systems. HVAC checklists to assist with maintenance and record keeping are available.
