About Us

The Challenge

Most buildings – even “green” buildings – are counterproductive: They use too much energy, provide poor and unreliable indoor air quality, are not safe in black-outs, and expensive to operate and maintain. They remain dependent on fossil fuels. The sad fact is the building industry is generally illiterate when it comes to understanding what makes buildings good or bad. Stakeholders don’t discern the direct connection between design and construction choices and climate, health, and social outcomes. Their judgment is impaired by bad habits. 

To complicate things, typically, the corrective steps proposed suffer from low expectations. All involved hedge on deep reform with imagined technology fixes around the corner. They fail to recognize their own power and fall well short of the systemic change required of our built environment.

Our Approach

The Passive House Network (PHN), formerly known as NAPHN, is a high-performance building literacy program. We provide comprehensive, high-quality Passive House education to stakeholders across the building industry – from architects and engineers, to builders and developers, to regulators and policymakers. We demystify the impact of design and construction choices, form knowledge-sharing networks, raise expectations, and transform how professionals fundamentally think and work.

Passive House is widely recognized as the most powerful tool we have today to produce buildings that rise to meet our challenges, forming the cornerstone of climate mitigation and adaptation, public health, and equity impacts.

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, is 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.

Two Passive Houses?

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 Certified Tradesperson. Specialized technical training is also available. PHN is dedicated to accelerating Passive House training across North America. Why Are There Two “Passive Houses”? Many are confused about how or why PHI and PHIUS are both promoting “Passive House” but do it separately.
