For residential buildings (including renovations) on sites of degree of sensitivity I or II according to the Ordinance for sound protection, and for office buildings for which a double facade takes into account the sound protection, the mechanical ventilation can be replaced by automatic windows. All living, sleeping and working spaces, as well as wet rooms in the building, must be equipped with automatic windows.
• Motorized window as an alternative to mechanical ventilation.
• Control for example via a program clock or according to the humidity of the premises.
• No filtration of outside air.
• Low acoustic insulation and thermal comfort compared to gentle ventilation.
• MINERGIE® standard for residential buildings (in particular renovation) on sites of degree of sensitivity I or II according to the Ordinance of protection against noise and for office buildings with double facade.
• All living, sleeping and working spaces, as well as wet rooms in the building, must have automatic windows.
• Windows must be arranged in such a way as to allow efficient diagonal shock ventilation.
• For good comfort, noise emissions must remain below the threshold of 55 dB (A) during the night.
• For school buildings, automatic windows are generally unsuitable because shock ventilation during lessons is not ensured due to thermal comfort and internal noise transmission (via the stairwell).
