As part of President Joe Biden’s National COVID-19 Preparedness Plan, released March 3, the U.S. Environmental Protection Agency (EPA) is releasing the “Clean Air in Buildings Challenge,” a call to action and a concise set of guiding principles and actions to assist building owners and operators with reducing risks from airborne viruses and other contaminants indoors. The Clean Air in Buildings Challenge highlights a range of recommendations and resources available to assist with improving ventilation and indoor air quality, which can help to better protect the health of building occupants and reduce the risk of COVID-19 spread.
"Protecting our public health means improving our indoor air quality,” said Michael S. Regan, EPA Administrator. “Today, the EPA is following through on President Biden’s plan to move our nation forward in a healthy, sustainable way as we fight COVID-19. Throughout the pandemic, building managers and facility staff have been on the frontlines implementing approaches to protect and improve indoor air quality to reduce risks and keep their occupants safe and healthy, and we are so grateful for their efforts. The Clean Air in Buildings Challenge is an important part of helping us all to breathe easier."
Infectious diseases, like COVID-19, can spread through the inhalation of airborne particles and aerosols. In addition to other layered prevention strategies, like vaccination, actions to improve ventilation, filtration, and other proven air-cleaning strategies, can reduce the risk of exposure to particles, aerosols, and other contaminants, and improve IAQ and the health of building occupants.
Key actions outlined in the Clean Air in Buildings Challenge include:
- Create a clean indoor air action plan;
- Optimize fresh air ventilation;
- Enhance air filtration and cleaning, and
- Conduct community engagement, communication, and education.
While the recommended actions cannot completely eliminate risks, they will reduce them. The Clean Air in Buildings Challenge presents options and best practices for building owners and operators to choose from, and the best combination of actions for a building will vary by space and location. Such steps would depend upon public health guidance, who and how many people are in the building; the activities that occur in the building, outdoor air quality, climate, weather conditions, the installed HVAC equipment, and other factors. American Rescue Plan and Bipartisan Infrastructure Law funds can be used to supplement investments in ventilation and indoor air quality improvements in public settings.
The EPA and the White House COVID-19 Response Team consulted with the U.S. Centers for Disease Control and Prevention (CDC), the U.S. Department of Energy (DOE), and several other federal agencies with roles in promoting healthy IAQ in buildings to develop the Clean Air in Buildings Challenge. The announcement also highlights an array of resources to help building owners and operators meet the challenge. The document will be made available in Spanish, Chinese Simplified, Chinese Traditional, Vietnamese, Korean, Tagalog, Arabic, and Russian.
