Assessment of Indoor Air Quality in School Facilities: An Educational Experience of Pathways for Transversal Skills and Orientation (PCTO)

Abstract

Italy’s education landscape witnessed a significant reform with the introduction of alternating school–work programs known as the School–Work Alternating System (PTCO). This innovative approach aims to enhance students’ transversal skills and career orientation while addressing crucial health concerns, including indoor air and environmental quality within school environments. This study, conducted at an Italian high school in collaboration with a university as part of a PTCO initiative, engaged eight students in environmental monitoring data collection. The students focused on thermal comfort, CO2 levels, and microbiological pollutants, collecting data in 19 classrooms and other school areas using professional instruments during February 2019. The results revealed varying thermal comfort levels and acceptable room temperatures, but inadequate ventilation and elevated CO2 concentrations, particularly in crowded areas like the cafeteria. Microbial analysis identified potential health hazards, underscoring the need for proactive indoor air and environmental quality measures. Post-intervention data showed improved CO2 levels, suggesting increased student awareness about the importance of air circulation. Engaging students in indoor air and environmental quality research through PTCO fosters critical thinking and civic engagement, which are crucial for sustainable development. Advocating for improved ventilation and periodic indoor air and environmental quality assessments aligns with the United Nations’ 2030 Agenda for Sustainable Development, particularly Goal 3 (Good Health and Well-being) and Goal 4 (Quality Education). The PTCO initiative empowers students to tackle real-world challenges like indoor air and environmental quality, developing essential skills and promoting positive change. Further research and policy efforts are needed to ensure equitable access to healthy learning environments, contributing to both educational success and long-term environmental sustainability.
