10 schools were studied in Tirol, four in Innsbruck. Additional interventions included a 5 minute video, posters in schools, a CO2 indicator light (5 schools), or installed automatic ventilation systems (2 schools). #ÖCSK2024#ECSA2024
The CO2 levels in schools (measured before COVID) were typically well over 1000 ppm, and are often over 2000 ppm. Gabriel Rojas's project is looking into whether things changed post COVID. #ECSA2024#ÖCSK2024
