When you get Phius certified, you automatically join the Phius Alliance, a community of passive house professionals throughout the U.S.: builders, developers, architects and others like you.
Build energy-efficient, comfortable structures that are good for people, planet and your bottom line.
A Holistic Approach
The Phius standard starts with a holistic, sustainable energy plan, rather than trying to compensate for shortcomings later.
Set Yourself Apart
Becoming Phius certified is the gold standard for building sustainably.
Boost Your Bottom Line
Passive buildings cost about 3-5% more than a conventional home, which shrinks as the scale of the project grows.
Phius is at its core about educating design professionals (builders, architects, consultants, academics, researchers) to make informed decisions to move us quickly to net zero, high performing, healthy buildings.
The CPHB training and certification is the absolute best building training I have ever had, hands down, when it comes to understanding best building and design practices for the region you are building in.
