The quality of school environments is crucial for student well-being and productivity. This study, conducted within the necessARIA project, focuses on improving environmental conditions in schools located in climatically distinct regions: Bolzano (south Tyrol) and Nereto, TE (Abruzzo region). Using acoustic, thermal, and air quality data, the study highlights differences in climate, temperature, and building materials, offering insights into environmental influences. In Bolzano, with its alpine climate, emphasizes the need for thermal insulation and acoustic control, while in Abruzzo, with its Mediterranean climate, air quality management and passive cooling were most relevant. The study, compliant with UNI EN 16798-1, aims to establish a standardized protocol to create healthier, sustainable learning environments, improving student comfort and performance. The findings provide valuable educational guidelines for policymakers and administrators, contributing to the broader literature on school environments.
