Irish Department for Education Guidelines and Recommendations for CO2 Monitors

The Department of Education has issued guidelines about installing CO2 monitors in schools across Ireland. The use of CO2 monitors can provide a useful general indication that areas/rooms within a building may not be adequately ventilated and can enable occupants to become familiar with the impact that activities, outdoor weather and window openings have on levels of good ventilation within a room. This information can be used to inform strategies for improving ventilation.


  • The monitor should 0.5 metres away from people and should not be placed near windows or ventilation grilles.
  • The monitor can provide information to occupants to indicate levels of poor ventilation. Both the Chartered Institute of Building Services Engineers and the Air infiltration and Ventilation Centre advise that CO2 concentrations above 1400 – 1500 ppm are likely to be indicative of poor ventilation and therefore require ventilation to be increased by opening windows, doors etc.
  • The lower the CO2 reading the higher the level of ventilation present in multi occupancy rooms and the higher the ventilation dilution effect that is possible while maintaining an appropriate balance between ventilation and comfort levels.
