Introduction:

Chiang Mai, Thailand, is facing a critical air pollution crisis, with Air Quality Index (AQI) levels frequently soaring due to high concentrations of PM2.5 particulates. This environmental challenge extends beyond outdoor spaces, underscoring the urgent necessity for effective Indoor Air Quality (IAQ) management, particularly in educational institutions. To address this issue, our case study examines the implementation of a hybrid natural and mechanical ventilation system integrated with IAQ sensors and control mechanisms in school environments. This innovative approach ensures the continuous circulation of clean, breathable air, thereby enhancing the health, comfort, and overall well-being of students and teachers. Testing results over a 30-minute period demonstrated a gradual reduction in PM2.5 levels, affirming the system's efficacy in improving IAQ.

This study highlights the critical role of maintaining high indoor air quality in schools and showcases Kruger Ventilation's dedication to fostering healthier, safer, and more productive learning spaces.
