PHIUS+ Certification/U.S. DOE Challenge Home

The PHIUS+ Certification program combines a thorough passive house design verification protocol with a stringent Quality Assurance and Quality Control (QA/QC) program performed on site by highly skilled and specialized PHIUS+ Raters. The benefits of PHIUS+ certification include:

  1. Comprehensive design and energy model review
    Passive house buildings in North American climates present unique design challenges; small mis-steps can lead to big problems. PHIUS+ certifiers are the most experienced passive house professionals in North America. They thoroughly review projects at the design stage, identify problems, and work with project designers to make projects work.

  2. Rigorous quality assurance
    Project testing and inspections are conducted by experienced HERS Raters, trained by PHIUS to work on PHIUS+ projects. The on-site inspections and testing help to assure PHIUS and the project teams that the buildings will perform as designed.  

  3. RESNET HERS Index Score
    Most projects will automatically receive a RESNET HERS Index score as part of certification. The RESNET HERS Index is the leading industry standard by which a home’s energy efficiency is measured. Many local, state, and federal financial incentive programs require a HERS Index to demonstrate compliance.

  4. One-Stop Certification Shopping Now Encompasses U.S. DOE Challenge Home
    PHIUS works with energy leaders like the Department of Energy’s Challenge Home program, Energy Star, and others. That means when you get PHIUS+ Certification you also get recognition from other programs.

  5. Listing on the PHIUS+ Certified Projects Database
    PHIUS+ certified projects are included with pertinent project information and photos on the PHIUS+ Certified Projects Database.
