Besançon equips its public primary schools with CO2 sensors

In its measures taken to fight against Covid-19, the town hall of Besançon is trying to optimize the duration of ventilation of the classes to also improve the quality of indoor air. The city thus announced on Monday that it had equipped its public primary schools with mobile CO2 sensors. The municipality has ordered 80 devices for a total amount of nearly 12,700 euros.

“Since Friday January 14, (the municipality) has distributed one sensor per school to each of the 64 public schools in the primary cycle (nursery and elementary schools)”, specifies in a press release the EELV mayor of Besançon, Anne Vignot. The CO2 sensors ordered “early January” have a “simple display” of three colors – green, orange and red – depending on the level of CO2 measured in the air.

A union demand

“The indications from the sensors provide information on the ventilation time needed to reduce the CO2 level in the classrooms”, depending on the size of the room, the number of pupils or even the air renewal capacity. Anne Vignot also underlines “that one of the most effective barrier measures in the fight against Covid is the ventilation of rooms” and thanks the staff who work in schools for their involvement in “the implementation of these measures in favor indoor air quality (IAQ) and the fight against the pandemic”.

Equipping classrooms with CO2 sensors is one of the flagship demands of the National Education unions. The Minister of Education, Jean-Michel Blanquer, admitted in early January that the deployment of these sensors in schools was “totally insufficient”. He then launched a “call to mayors” to take advantage of the state fund of 20 million euros to provide their schools.
