Passive House Windows and Doors Continue to Wow
Among the new wave of highly efficient windows and doors, some are going beyond the strict energy criteria set by the Passivhaus Institute (PHI) to offer additional green features and innovations designed to reduce overall environmental impact. Most frontrunner products are imported, suggesting European manufactures continue to lead in quality (see “European Windows for Passive House Buildings”). However, U.S. manufacturers have begun to certify windows through the international standard and may soon offer products with competitive performance and lower embodied transportation energy.
