The North American Passive House Network (NAPHN) is leading the transformation of the building industry to low-energy, high-performance Passive House design and construction. We support the widespread adoption of the international Passive House design and construction standards, building science principles and protocols.

A non-profit educational organization – NAPHN’s work is internationally recognized. NAPHN is focused on the inflection point between policy and implementation. We partner with leading stakeholders across all building sectors, including: governments, professional associations, manufacturers, owners, builders, labor organizations, and educational institutions – to make the transformation complete. See our about us document here.

Our Vision:

A sustainable, post-carbon, all-renewable energy future – supported by buildings that are efficient, comfortable, affordable, resilient and healthy.

Our Mission:

The transformation of the built environment, using the tools developed by the Passive House Institute, in a critical effort to combat global warming. We provide training, conferences, and other events to both engage and educate design and building professionals, policymakers, and the general public. We support the success and vitality of the Passive House community.

For over 26 years the Passive House Standard has been the state-of-the-art scientific foundation of high-performance and net-zero buildings, around the world. Training qualified professionals is an essential prerequisite for successful Passive House construction. Basic training can be toward becoming a Certified Passive House Designer, Consultant or a Certified Tradesperson. Specialized technical training is also available. NAPHN is dedicated to accelerating Passive House training across North America. Why Are There Two “Passive Houses”?
