Passive buildings are more than just well-built structures, they help contribute to the quality of life of the people who live, work, and learn in them. At PHIUS we believe that the benefits of passive buildings should be enjoyed by all, and that these levels of performance should be the market standard – not the exception.

PHIUS is a 501(c)(3) organization committed to making high-performance passive building the mainstream market standard. PHIUS is transforming the building sector by developing and promoting North American specific standards, practices, and certifications for buildings, professionals, and products to create structures that are durable, comfortable, healthy, and super energy efficient.

Founded in 2003, PHIUS has trained over 2,000 architects, engineers, energy consultants, energy raters, and builders in the passive building standard. The organization is the leading passive building research and information provider in North America. PHIUS released the PHIUS+ 2015 climate-specific building standard, developed under a DOE grant in partnership with Building Science Corporation, in March of 2015. In addition to the DOE, PHIUS has also established strategic relationships with key organizations including RESNET and the Home Innovation Research Labs, among others. The organization has received funding from the Richard King Mellon Foundation and, more recently, the John D. and Catherine T. MacArthur Foundation.

Through its Passive House Alliance US (PHAUS) program, a membership-based organization with over 800 members across 18 local chapters and dozens of corporate sponsors, PHIUS is building a robust national network of passive building communities across North America.
