What is a Passive House?

Passive House (Passivhaus) is considered to be the most rigorous voluntary energy-based standard in the design and construction industry today.

Climate change is the challenge of our generation.  Growing evidence is driving international consensus for action to limit global warming below 2°C.  Buildings consume up to 40 percent of global energy use and contribute up to 30 percent of annual global greenhouse gas emissions – they are a key piece of the puzzle towards a low-carbon future.

Passive House (Passivhaus) buildings consume up to 90 percent less heating and cooling energy than conventional buildings.  Applicable to almost any building type or design, the Passive House high-performance building standard is the only internationally recognized, proven, science-based energy standard in construction. Certification ensures that designers and consultants are expertly qualified to design buildings to meet the standard.

The benefits of employing Passive House standards include fine-tuned control over indoor air quality and temperature with simple to use and durable systems, making them extremely quiet and comfortable throughout the changing seasons. The reductions in operating costs quickly make up any additional costs associated with construction, and the reduced carbon emissions provide priceless peace of mind.

Passive House (Passivhaus) is at the foundation of how we build better. It is how we feel better.
