Buildings that are comfortable, healthy, and use very little energy.
The Passive House Network (PHN) is the US nonprofit that trains and connects people who support, design, build, and own Passive House buildings, working with the Passive House Institute (PHI).
Passive House is PHI’s international building standard. It sets clear limits for energy use and comfort, and buildings around the world meet them.
And you don’t learn it alone. PHN chapters meet across the country, online and in person, to talk through real projects. Anyone can come, at any stage.

An expansive and complex knowledge base was well-documented, presented and supported throughout the program. Highly recommend!”
