The PHIUS+ Standard

The PHIUS+2015 Passive Building Standard released by Passive House Institute US (PHIUS) in 2015 is the only passive building standard on the market based upon climate-specific comfort and performance criteria. Buildings designed and built to this standard perform 60-85% better (depending on climate zone and building type) on an energy consumption basis when compared to a code compliant building (International Energy Conservation Code IECC 2009).
 
The cost-optimized PHIUS+2015 Standard is spurring new growth in passive buildings from coast to coast, with the most significant gains coming from the multifamily housing sector. Certified and Pre-Certified PHIUS+ projects now total more than 1 million square feet across 1,200 units nationwide. As more units come online every day, more families are enjoying the affordability, resiliency, and health benefits of passive buildings.

PHIUS+ OFFERS UNPARALLELED QUALITY ASSURANCE

PHIUS+ is the only passive building certification system that requires third party quality assurance/quality control (QA/QC). The QA/QC process is essential to making the case to investors and stakeholders that your project will successfully achieve modeled levels of performance.

THE PHIUS+ STANDARD IS NOW WITHIN REACH

The cost-optimized, climate-specific PHIUS+2015 Passive Building Standard, developed in cooperation with Building Science Corporation under a US Department of Energy grant, pins down the sweet spot between investment and payback to achieve the most comfortable and cost-effective building possible for a given location.
