Protect your home from bad indoor air

 

(akz-o). Whether it's a new building or an extensively modernized old building - for reasons of energy efficiency, not only the thermal insulation but also the tightness of the building is optimized these days. If people do not ventilate sufficiently, this has a negative impact on indoor air quality.
Breathing and fumes from furniture, cleaning products and cigarettes can lead to high concentrations of CO₂ and volatile organic compounds (VOCs) in the house. Then there is a risk of headaches, fatigue, susceptibility to infections or allergies and eye irritation. If the humidity becomes too high due to sweating, cooking, showering and drying laundry, this can even lead to the risk of mold forming.
Experts therefore recommend ventilating three to five times throughout the day for five to fifteen minutes, depending on living habits and the room. Ideally, you can ensure there is a draft with windows wide open on several sides of the apartment. However, it is obvious that this is hardly possible for working people, for example. Convenience or concerns about moisture damage caused by rain also mean that these recommendations are rarely implemented consistently. There are therefore ways to ensure air exchange automatically.
 

In addition to a central mechanical ventilation system, the installation of which is very complex and expensive - especially in modernized old buildings - electric or solar-powered windows now also ensure the necessary air change. With Velux roof windows, for example, regular ventilation intervals can be easily set using the app. The windows then open and close automatically on a schedule without anyone having to worry about it. However, no one has to be afraid of sudden rain: thanks to a built-in rain sensor, the roof windows close by themselves. This technology is further optimized in combination with the Velux Active SmartHome system. A sensor measures the humidity and CO₂ concentration in the room. If a limit value is exceeded, depending on the setting, the roof window or the ventilation flap opens automatically until there is sufficient ventilation.
