Since we are insulating more and more and are filling the slightest opening or crack, indoor air is no longer renewed naturally. As a result, it may be more polluted than outdoor air. During class day, pupils are spending hours in classrooms with unhealthy air. Some consequences of this are stenches, irritated eyes, and headaches. But also, and that is the most worrying, stale air induces a high CO2 level variation. When the CO2 level is high, it makes pupils becoming restless and disruptive. They lose their concentration and their learning ability decreases significantly. No need to say that a healthy indoor air atmosphere is worth it, and it is our responsibility to offer them a good learning environment.
According to studies, indoor air in schools can be twice, or even five times, more polluted than outdoor air. The exposure to indoor pollutants is the major key contributor to asthma and the spread of most infections and allergies
A solution may be to open windows and doors, but this will create drafts, expose learners to outdoor noises, and induce a waste of energy. A much better solution is to ventilate artificially. A high efficiency ventilation system assures a better learning environment by purifying the air. Its heat recovery feature permits to recover calorie watts without wasting electricity watts.
When the ventilation rate is doubled, researches show that the students’ perfWce in school rises by around 15%.
