Air temperature and CO2 concentration were measured in classrooms with ventilation system from April 2018 through March 2022. It is assumed that, under the COVID-19 circumstances, windows of the classrooms, where ventilation system was working, were basically kept open throughout a year. The average air temperature at foot level was 11°C during winter period because of cold outdoor air infiltration. The estimated ventilation rate tended to decrease during winter period. However, the estimated ventilation rate per person more than 30 m3/h was obtained in case of half number of pupils in the classroom with Hybrid-Flexible lesson for the whole day.
