The PHIUS+ Standard is the Best Route to Net Zero

The PHIUS+ Passive Building Standard ignited tremendous growth in passive building from coast to coast. The most significant gains are in commercial and in multifamily housing. PHIUS+ Certified and Pre-Certified projects now total more than 1 million square feet across 1,200 units nationwide.

PHIUS+ represents the sweet spot where aggressive carbon and energy reduction overlap with cost-effectiveness because the WUFI® Passive modeling tool is the most potent passive building-modeling tool available. Developed by Fraunhofer Institute for Building Physics in collaboration with PHIUS and Owens Corning, WUFI Passive is a user-friendly software uniquely suited to North America's varying climate zones.
