Abstract

The concentration of CO2 was measured in three measurement campaigns using either spot measurements or week-long continuous measurements. The results, once again, documented that ventilation is inadequate in many Danish schools. More classrooms exceeded the recommended limit of 1000 ppm in the campaign using continuous measurement (91%) than in the campaign using spot measurements (60%). Pupils were exposed to CO2 concentrations exceeding 1000 ppm in almost half of their time in school during winter but only 12% during summer.
