Preparing Your Building For The Return To Work

Airborne viruses are present in your building, understanding and adjusting air movement in your HVAC system can help control the spread of dangerous viruses.  The following recommendations from ASHRAE allow building operators to manage their HVAC systems to control the flow of air in their buildings.

  • Increase outdoor air ventilation
    • Disable demand-controlled ventilation (DCV). Use caution in areas with high levels of airborne pollutants.
    • Adjust outdoor air damper positions as high as 100% and eliminate recirculation.  In extreme weather conditions, HVAC systems may not be able to fully condition the building.
  • Employ higher MERV-rated filtration media to MERV-13 or the highest compatible option, seal edges of the filter to limit bypass.
  • Run systems longer hours to reinforce changes to DCV and air filtration.
  • Utilize portable air cleaners with HEPA filters as a temporary measure.
  • Install Ultraviolet Germicidal Irradiation (UVGI) in supply air ductwork, particularly in high-risk spaces such as waiting rooms and lobbies where a high concentration of people are expected.
