The Center for Green Schools at the U.S. Green Building Council (USGBC), with technical support from American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), released survey results from school districts across the country, detailing measures they have taken to improve indoor air quality (IAQ) in school buildings in response to the COVID-19 pandemic.
The responses cover more than 4000 schools serving 2.5 million students in 24 states.
“Indoor air quality continues to be a critical concern as more teachers and students are returning to the classroom,” said Anisa Heming, director of the Center for Green Schools at USGBC.
“Increasing clean air circulation for our teachers and students is vital to promoting public health and is a key green building strategy for school buildings. Our aim with this report is to inform policymakers and nonprofits that support our schools of the challenges that our education institutions face in combatting the spread of COVID-19, particularly given the deficient state of many school buildings across the country,” Heming said.
The report shows what school districts have prioritized, which actions they have taken, how they have made decisions, and what the consequences have been. The results of the survey show that schools have implemented some protective measures to improve IAQ, prioritizing ventilation and filtration to reduce the transmission of the virus. However, school districts still have unmet needs and face numerous challenges related to high costs and outdated building infrastructure.
“This report provides a wide-scale, foundational framework to school leaders and lawmakers alike towards the implementation of new building design guidelines and to advance health and sustainability goals, while instilling confidence in the places where people learn,” said 2020-21 ASHRAE president Charles E. Gulledge III, P.E.
Additional findings from the survey:
- the most-frequently cited challenge to implementing protective air quality measures at schools was school buildings were not designed to support the strategies that were being recommended;
- school districts which are able to act have leaned heavily on their mechanical systems, such as increasing air supply through HVAC systems or upgrading filters to implement protective air quality measures for students and teachers;
- only two-thirds of respondents were regularly monitoring IAQ before the pandemic, indicating providing time, staff, and funding for regular monitoring and data collection has not been a priority for many districts in the past; and
- respondents want to continue the measures implemented during the pandemic, citing student and teacher health, and 70 percent of school districts plan to continue some or all strategies they have implemented.
This past spring, President Joe Biden signed the $1.9 trillion American Rescue Plan into law, which includes close to $130 billion for K-12 education, and several other provisions affecting schools. The funding headed to schools represents an opportunity to support student needs during the ongoing pandemic and to address persistent inequities, a press release from USGBC said.
“Schools can use federal funds for a variety of items relevant to the building industry and green building, including school building improvements that reduce risk of virus transmission and exposure to environmental health hazards,” said Heming.
