Passive House certification is a quality assurance process designed to ensure project compliance with a strict energy standard that targets up to 90% energy savings when compared to a conventional project. The Passive House Institute determines whether a project meets quantitative levels for airtightness and very low heating demands. This is achieved through extremely durable building materials and high-level detailing of components and intersections. Buildings designed to this standard have high levels of occupant comfort and health with extremely low energy use. Projects are registered and certified through the Canadian Passive House Institute.
