Teaching and learning take a good indoor climate. The Danish Ministry of Health describes in the report, “Indoor climate in schools”, the negative influences that a poor indoor climate have on the education. The symptoms are, amongst others, sleepiness, fall in the learning ability and problems in concentrating. In the report the Ministry offers a number of recommendations.
At the same time, a recent study, elaborated in the USA, shows that creativity and the learning ability drop with a rising CO2 level in the air.

Studies from e.g. DTU (Technical University of Denmark) prove that somewhat more than half of the Danish class rooms have CO2 levels beyond the limit of 1,000 ppm.
Fresh air in a class room can be assured either by a ventilation system or by a consequent ventilation during and/or between classes. The relatively many persons in a relatively small room takes a considerable air turnover.
The measurements – what use do they have?
The IC-Meter be used for the documentation of indoor climate and ventilation conditions, it can activate the users and e.g. be used for a meter station in a customized ventilation system.
Teachers, students and the school Board will initially all be able to receive the indoor climate measurements and the calculated key values for ventilation.
The statistics – what use do they have?
The statistics of the indoor climate are distributed as to if there are persons present in the room or not. From a health point of view it is interesting to document the indoor climate for the periods that the room is in use and not for the longer periods that these kind of rooms are not in use.
