- How to Get Certified
The PHIUS+ 2015 Passive Building Standard certification program is the only passive building certification system requiring third party quality assurance/quality control (QA/QC). The rigorous QA/QC process associated with full certification verifies to investors and program managers that built projects achieve modeled levels of performance.
The PHIUS+ 2015 Standard is being co-promoted by the US Department of Energy (DOE) as the next level of high-performance building standards. PHIUS+ 2015 certification requires that in addition to meeting passive building standards and principles, projects must also comply with DOE-accepted performance practices including the US Environmental Protection Agency’s Indoor airPLUS and WaterSense program requirements.
PHIUS+ 2015 certified residential projects also qualify for the DOE’s Zero Energy Ready Home program, which recognizes high-performance homes that are so energy efficient most or all annual energy consumption can be offset with renewable energy. The DOE offers a Lender Partner Agreement whereby lenders who become partners will have greater ease in financing homes with lower risk because these homes are built to much more rigorous standards than minimum code and afford occupants significantly lower operation costs.
