Swegon: how do we know that the indoor climate in our schools is sufficient?

Since the outbreak of the COVID pandemic awareness has grown rapidly about the importance of fresh air indoors and increased ventilation rates. Much of the attention has been focused on schools – our children’s working environment – as a potential place for contamination and spread of viruses. The debate has focused on the ventilation of classrooms and how to make sure that the air quality and air exchange in the room is correct, and how to increase the ventilation rate where needed. Hence a lot of schools have started to install carbon dioxide (CO2) sensors.
