Building Air Systems
A building air system provides a controlled environment for personnel working in the building and provides the needed air adjustments. This is done by using exhaust and air makeup to control contaminates and preserve the building structure. This course describes the purpose of building air systems, makeup and exhaust air systems, conditioning methods, and air balance.

Sample Video Transcript
The type of air conditioning methods and equipment used is determined by the building occupancy. For example, office areas would typically use HVAC equipment with distribution ducting equipped with fans, cooling and heating coils, humidity control equipment, and necessary filters. While in manufacturing areas, supply fans with inlet filters direct air through steam, or glycol heating coils in cold climates. On the wet end of paper machines where exhaust air streams contain large amounts of water and fiber particles, separators may be used to separate water droplets and contaminants from the exhaust air stream before entering the fan. Separators are essential to prevent ice formation on building roofs in cold climates.
