Large-scale CO₂ measurement campaigns in Danish schools

Abstract

In two large measurement campaigns performed in 2009 and 2014 more than 1500 spot measurements of CO₂ were made by pupils in Danish primary school classes. In 2009 56% of the measurements exceeded the recommended value of 1000 ppm CO₂. This percentage had increased to 60% in 2014. Changing the behaviour of the pupils had a positive effect, as the proportion of classrooms exceeding 1000 ppm CO₂ in separate measurement (students outside and airing in the break preceding the measurement lesson in which the measurement was made) was 39%. The principle of ventilation had a substantial impact on the measured CO₂ concentrations. In 80% of the classrooms with natural ventilation the concentration of CO₂ exceeded 1000 ppm, while the fraction was 40% in classrooms with balanced mechanical ventilation.
