Correct ventilation in kindergartens

Fresh air in daycare rooms for the health of young and old

For kindergartens, ventilation is the most important measure to protect against infection with infectious diseases. Other hygienic protective measures, such as keeping your distance or adhering to sneezing and coughing labels, are difficult to implement in a group of small children. In addition to avoiding infection, the CO2 concentration in day-care centers is also decisive.

The German Federal Environment Agency recommends maintaining an average CO2 concentration of 1000 ppm for day-care centers. In general, the design can be based on DIN EN 15251: 2012 and DIN EN 16798-3.

Depending on which classification is agreed, outside air volume flows between 20 and 36 m³/h per person are recommended. The combination of mechanical ventilation with heat recovery and window ventilation is an effective solution for exchanging the air in accordance with the recommendations of the German Federal Environment Agency, without the rooms cooling down too much, the children having to freeze and without expensive reheating. The ventilation through wide-open windows is reduced to a minimum.


Decentralised ventilation of group rooms

Planning example for ventilation in kindergartens...



  • Between 20 and 36 m³/h per person
Example Floor Plan Ventilation in Kindergartens



The iV-Office creates continuous basic ventilation within the specified requirements for sound emissions (here: 40 dB (A)).

In this case, the iV-Office is designed with 30 m³/h per device, with 4 devices in the room (two pairs of devices) this results in an outside air volume flow of 120 m³/h. It corresponds to 10 m³/h per person with a group of 12 people. In addition, before and after use, the air exchange can be temporarily increased to up to 180 m³/h. In addition to the removal of CO2, the mechanical ventilation also prevents infections.


Existing aerosols are transported to the outside via the devices and the fresh air supplied lowers the concentration of viruses in the room air. In order to achieve the required air exchange in this application, the ventilation should be supported by opening the windows temporarily.




  • Discharge used room air
  • Minimize the risk of infection
  • Simple retrofitting in the outer wall
  • Set the ventilation intensity intuitively
  • Heat recovery through ceramic core
  • Fresh air at a comfortable temperature
