The certification of a Passive House through the Passive House Institute or any of its accredited Building Certifiers offers enhanced quality assurance. The vast experience of these certifiers benefits designers throughout the planning process whereas the certification itself provides evidence of the building’s quality. Many (but far from all) Certified Passive Houses can be found in this global database, and world map.
The North American Certifiers Circle (NACC) is a group of organizations actively certifying buildings to the international Passive House Standards (Classic, Plus, Premium, and EnerPHit) in North America. The NACC works cooperatively to serve the public. Download the two-page flyer HERE.
