Clean indoor air is an investment that enhances the health and productivity of the entire school community. Effective ventilation and filtration do more than just clean the air; they defend students against seasonal respiratory bugs and protect children from asthma attacks, which cause millions of missed school days every year. Research confirms that fresh air translates to higher test scores, whereas insufficient fresh air circulation and elevated indoor carbon dioxide levels limit student focus and lower cognitive performance. Teachers benefit just as much as students, as healthy school environments drastically improve job satisfaction and keep teachers from leaving the profession. Ultimately, managing indoor air quality (IAQ) saves school districts money. By adopting a proactive written IAQ Management Plan focused on preventative upkeep, school districts can stay ahead of costly emergencies like toxic mold outbreaks and sudden HVAC system breakdowns.
The Center for Green Schools at the U.S. Green Building Council is here to help. The Center for Green Schools provides free locally relevant education and peer-to-peer connections to K-12 school district staff on IAQ management that also prioritizes energy efficiency. This support includes local in-person workshops, virtual trainings, and on-demand resources. Targeted resources include:
School District Energy Efficient Indoor Air Quality Management Plan Toolkit: Created by the Center for Green Schools at USGBC, in partnership with American Lung Association, Go Green Initiative, and the University of Utah. The Toolkit guides K-12 school districts through each component of IAQ management, while also prioritizing energy efficiency. The Toolkit includes example IAQ Management Plan language, case studies, and an easily editable IAQ Management Plan Template that school districts can customize to their needs.
School IAQ Fact Sheets: The IAQ Fact Sheet Series is designed to help people without a technical background understand details about indoor air quality (IAQ) so that they can make important decisions for their schools.
Clean Air in Schools Course: A free, on-demand introductory training on IAQ best practices, co-developed with the Efficient and Healthy Schools Program and the EPA.
This work supports the national Creating Healthy and Efficient School Environments: Indoor Air Quality and Energy Management Initiative, of which the Center for Green Schools is a lead partner, along with the American Lung Association and the Go Green Initiative.
