Top 5 Tips: Pro-active Commissioning Helps Improve IAQ

Better indoor air quality leads to “increased work performance, reduced Sick Building Syndrome symptoms, reduced absence, and improved thermal comfort for millions of office workers.” – Results from  a study by Lawrence Berkeley National Laboratory and the Environmental Protection Agency

Improving indoor air quality is very important, especially right now with a resurgence of COVID cases seen around the country. And commissioning can significantly contribute to improving indoor air quality in buildings. Here are the top five pro-active commissioning activities that building owners and managers can do now that will make a big difference later:

  • Verify how much outdoor air ventilation is actually being delivered to your building through air flow measurements. Buildings are designed to provide outside air according to ASHRAE 62.1 and the best way to ensure buildings are still operating as designed is through commissioning.  
  • Identify opportunities to increase outside air to the space to improve IAQ. In most cases this is a low cost, high impact solution for better IAQ which leads to healthier and higher performing occupants. 
  • Confirm optimum filter selection and change frequency. Most building systems can handle higher MERV rated filters to reduce the amount particulates recirculating through the system.  
  • Review potential for the addition of UVGI systems to main air handlers. UVGI applied to the coil deactivates viruses and keeps your coil clean which improves maintenance and energy costs. 
  • Commission HVAC equipment to ensure continued efficient and effective operation for tenant comfort, indoor air quality, and energy costs. 

To learn more about commissioning and how it can improve indoor air quality, please reach out to WB's expert commissioners, Ted Blackinton ( or Alex Bolovschak ( 

Coming soon, we will be exploring one effective strategy of providing outside air to a space: ERVs.
