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.
In the next 20 years, Phius will be the market standard as far as I'm concerned.
Phius has given us the education, the tools, the building science knowledge, and the ongoing community support to put into practice what 16 years ago was still a vision: buildings that leave no trace on the climate.
Phius' mission is to combat climate change by making high-performance passive building the mainstream standard, in the quest for zero. We go beyond professional certification and standards to foster collaboration. Phius plays a key role in policy initiatives that have spurred growth in affordable, multifamily passive housing in the U.S. We also work tirelessly with federal, state and local governments to educate them on the value of incorporating Phius standards into their building codes.
