The Federal Environment Agency has presented recommendations for the ventilation of schools in the corona pandemic. "To protect yourself from infectious particles, the air should be changed three times per hour.
This means that the room air is completely exchanged for fresh air from outside three times an hour," writes the office. In the cold season of the year, the room should be ventilated every 20 minutes with the windows wide open for 3 to 5 minutes during lessons -
so-called burst ventilation. In addition, there should be ventilation during the entire breaks. The office advises against only opening the door for ventilation, because small aerosols could then spread from one room through the hallway to other classrooms.
Ventilation with only one open or tilted window is also not recommended.
