Webinar: Using CO2 to Assess Ventilation

March 11, 2021 @ 2:00 pm - 3:00 pm

Using CO2 to Assess Ventilation

On Feb 19 the CCTC held our Indoor Air Quality Summit. This webinar from the Maine Indoor Air Quality Council touches on some of the topics discussed during our summit. It is free to register.

Thanks to COVID-19, facilities managers and owners have become acutely aware of the need to ventilate indoor spaces to reduce virus exposures. Knowing whether or not adequate ventilation is available is critical.

You cannot “see” ventilation in indoor spaces, because air and air movement are invisible. But you can measure it. One of the easiest methods to assess ventilation is by measuring CO2. Because CO2 indoors is generated by people exhaling into an indoor space, measuring how much CO2 is present can indicate whether or not there is sufficient ventilation indoors to exhaust CO2 and other airborne pollutants, thus reducing virus exposure.

Measuring CO2 isn’t as simple as waving a magic wand (a hand-held CO2 meter) or installing a magic box (electronic controls for an HVAC system). It’s important to know when, where, and how to measure CO2 properly, so that users can be accurately informed on their ventilation strategies.

This one-hour webinar will briefly discuss various methods to use CO2 measurements to assess ventilation, and will discuss specifics of where, when, and how to properly measure CO2 to accurately inform users of ventilation options.

Program Outline:

  • How do we think about indoor air quality, what are good indicators to look at to help establish and identify possible issues
  • Why do we look at carbon dioxide as an indication of general air quality
  • What reading ranges look like
  • Particulate counts in environments and how does this help in identifying areas to be addressed if necessary
  • Metering; what should you have in your “Tool Bag”?
  • Understanding the reading from your “Tool Bag”
  • Q&A
