Maintaining the proper parameters of the microclimate in classrooms and classrooms to ensure the well-being of students is an important social task, since young people spend a significant part of their time in educational institutions. Failure to admit microclimate parameters in class rooms, in particular due to the high concentration of CO2, leads to deterioration of the state of health and disability of the students, as well as to the inadequate absorption of the training material.

In the last decade, modernization of school buildings in Ukraine is being carried out. Thermorenoval measures such as thermal insulation of exterior walls and replacement of existing windows are most often used. Installing hermetic metal-plastic windows significantly reduces the heat loss of premises, but leads to disturbance of air regime, as outdoor air infiltration is often the only source of external fresh air supply.
