Passive House (Passivhaus in German) is the world's most rigorous voluntary energy performance standard for buildings. It represents the pinnacle of energy-efficient construction, reducing heating and cooling energy use by up to 90% compared to conventional buildings.
Developed in Germany in the 1990s, the Passive House standard has been proven in over 60,000 buildings worldwide across all climate zones. It's not a brand or proprietary system - it's a performance-based standard that can be achieved using various products and techniques.
Windows are critical to Passive House certification. They must meet strict requirements for thermal performance, air tightness, and installation quality. Our certified window systems are specifically designed and tested to meet these demanding standards.
