Venue ventilation for COVID-19

venue ventilation COVID-19 Attention, meeting planners! Safe meeting venue ventilation for COVID-19 is critical. As we start thinking about returning to in-person events, it’s crucial to check that venues are upgrading their HVAC systems to handle potentially virus-infused air.

There has been little public discussion on this important topic. In this post, I’ll explain why questions about venues’ HVAC safety should be at the top of your site visit checklist.

Before we start, I need to make clear I’m not an HVAC engineer. My (perhaps) relevant background is an ancient Ph.D. in high-energy particle physics, and two years spent exploring ventilation systems—specifically air-to-air heat exchangers—when I owned a solar manufacturing company in the 1980s.


Since the pandemic began, the science on COVID-19 transmission has evolved rapidly. Because early theories turned out to be inaccurate, current preventative measures are frequently misdirected. So I’ve included a short history of theories of COVID-19 transmission that shed light on the reasons we’ve underestimated the importance of ventilation in creating safe environments for indoor events.

Next, I’ve outlined what current research indicates venues and properties should be doing.

Finally, I’ve aired my concerns about how well venues and properties are responding to the safety concerns I’ve introduced.
