Passive houses and low-energy buildings are systematically equipped with dual-flow mechanical ventilation systems to meet airtightness standards and minimize heating needs. The system ensures continuous air renewal while conserving thermal energy. High-performance filtration eliminates pollen, dust, and pollutants.
Energy-efficient renovations in detached houses benefit from the installation of a double-flow mechanical ventilation system (MVHR) to improve thermal comfort and eliminate cold drafts. Supply vents distribute preheated air into each living space, while exhaust vents remove stale air.
