Opening windows and doors helps ... but what with winter approaching?

Venting by always leaving windows and doors open does have a positive effect on indoor air quality, as the Sense already demonstrated during some test setups in Belgian classrooms. Only ... what about with winter approaching?

Going back for a moment to Sept. 1 ...

It was "breaking news" at the start of the school year: ventilation is a priority to minimize the risk of airborne spread of the Covid-19 virus in crowded classrooms. So windows and doors open wide, so fresh air is constantly available and healthy indoor air doesn't give the virus a chance. And it's paying off. Renson equipped about 10 Belgian schools with the Sense at the end of August as a pilot project. And the measurement results show that with the windows and doors open, even in classrooms without a ventilation system, CO₂-levels barely rose above 1200 ppm 7.7% of the total time. Previously (read: before the September 1 restart), when windows and doors in those same classes were still mainly kept closed, that was still found to be the case 29.9% of the time.

But what with winter approaching?

So ventilating by always leaving windows and doors open does have a positive effect on indoor air quality. But with winter approaching, this is already much less obvious as a solution. And then the Sense really is a handy extra pair of feelers in the classroom, at home or in the office: what you don't notice yourself, it does: it warns you when the air quality is deteriorating and so it is high time to bring in fresh air. Then the window can still be opened, just until the Sense gives you "blue light" again.

Long-term solution? Continuous and controlled ventilation

Ok, the Sense may notify you when indoor air quality leaves something to be desired, but ultimately it's still up to you to manually act on its signal. If you really want to be able to live, teach or work comfortably, you need to look for a solution that relieves you. And that's where Renson's Smartzone ventilation comes in. With a smart ventilation device that - like the Sense - reduces CO₂but also monitors moisture and pollutants, you never even have to worry about healthy indoor air. In fact, such a ventilation system automatically adjusts itself to your needs and requirements. The figures from the classes with a ventilation system in the pilot project speak for themselves. With 99.8% of the total time below 1200 ppm CO₂ in the air, there is virtually always automatically the best possible indoor air quality in that case.
