HVAC Strategies to Improve Indoor Air Quality in a Post-Coronavirus World
Indoor air quality is becoming more paramount in all types of facilities in light of the Coronavirus Disease 2019 (COVID-19) pandemic. According to the Environmental Protection Agency, Americans, on average, spend 90 percent of their time indoors. As businesses reopen and employees return to work, building owners are seeking strategies to protect the health of their building occupants. While there are several factors to be considered and methods available to control the spread of airborne pathogens, the obvious method is through the HVAC systems.
In the white paper, “HVAC Strategies to Improve Indoor Air Quality in a Post-Coronavirus World,” Kris Schnitgen, PE, LEED AP, Principal and Senior Mechanical Engineer at Kohrs Lonnemann Heil Engineers, Inc. (KLH Engineers), provides an in-depth analysis of the advantages and challenges of several HVAC strategies used to help eliminate airborne pathogens including:
- HVAC system operation.
- Outdoor airflow.
- Air filtration.
- Bi-polar ionization.
- Ultraviolet and germicidal irradiation (UVGI).
- Temperature and humidity control.
- Real-time reporting of indoor air quality.
Implementing only one of these methods will not be as effective as implementing several lines of defense. Each option should be carefully weighed and studied based on the application and retrofit conditions. In addition, some methods will require the expertise of a mechanical engineer as well as personnel training following implementation.
