The Impact of Outdoor Air Ventilation in School Corridors

摘要

In the United States, students spend on average 6.64 hours in school, making the need for improved indoor air quality (IAQ) in school buildings highly critical. About 55.4 million students were enrolled in U.S. elementary and secondary schools in 2021. Worldwide, there were about 614 million secondary students and 739 million primary students, representing more than 17 of the global population. As the U.S. Environmental Protection Agency (EPA) reports, school environments affect attendance, concentration and performance of everyone inside school buildings, including students and educators. In this article, the authors present simulation results using the U.S. Department of Energy (DOE) Secondary School prototype building to demonstrate the impact of providing outdoor air ventilation to the corridors above the current required rate in ASHRAE Standard 62.1-2022.
