EPA launches clean air in buildings challenge to improve IAQ

New guidance is intended to help building owners and operators improve indoor air quality and protect public health.

The U.S. Environmental Protection Agency (EPA) has launched the Clean Air in Buildings Challenge, a call to action and concise set of guiding principles and actions to assist building owners and operators reduce risks from airborne viruses and other contaminants indoors. The guidance is part of President Biden’s National Covid-19 Preparedness Plan released earlier this month.

The Clean Air in Buildings Challenge highlights a range of recommendations and resources to help improve ventilation and indoor air quality, which can help to better protect the health of building occupants and reduce the risk of Covid spread.

EPA Administrator Michael S. Regan said, “Protecting our public health means improving our indoor air quality. Today, 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 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 indoor air quality and the health of building occupants.

Key actions outlined in the Clean Air in Buildings Challenge include:

• Create a clean indoor air action plan
• Optimise fresh air ventilation
• Enhance air filtration and cleaning
• 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 heating, ventilation, and air conditioning (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.

EPA and the White House Covid-19 Response Team consulted with the Centres for Disease Control, the Department of Energy, and several other Federal agencies with roles in promoting healthy indoor air quality in buildings to develop the Clean Air in Buildings Challenge.
