Ventilation
Dual-flow ventilation: healthy air and up to 20% savings thanks to heat recovery.
Poorly ventilated homes suffer from humidity, mold, energy losses and respiratory issues. A dual-flow mechanical ventilation (MVHR) system renews the air continuously while recovering heat from the exhaust air.
Up to 20% energy savings through heat recovery, significant improvement in indoor air quality, reduced health risks. Cantonal subsidies for dual-flow ventilation range from CHF 3,000 to 5,000.
A renovated home without proper ventilation equals guaranteed issues in the medium term. Ventilation boosts heating performance, prevents building damage and improves long-term comfort.
