Biological Air Quality Considerations for Non-Healthcare, As Built Environments

Air quality has become a focus of facility considerations since the pandemic started. The Global Biorisk Advisory Council™ (GBAC) offers access to a FREE peer-reviewed article from the GBAC-TIPS Journal to provide insight on measures a facility and those involved in cleaning facilities should take into consideration to control the spread of infectious agents, with a particular concern for those spread through airborne routes.

Here’s a preview of the content from GBAC-TIPS:

The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) recommends certain low-cost measures that all building owners and operators should consider improving the effectiveness of their respective HVAC systems (ASHRAE, Ashrae Epidemic Task Force 2021).

First, the operator should ensure the HVAC system provides the minimum levels of outside air prescribed by codes and standards. Fresh air dilutes the concentration of contaminants thereby reducing the risk of infection. Secondly, air filters that achieve…
