The PHIUS+ Certification program is built on the new, PHIUS+ 2015 passive building energy standard, which has been cost-optimized by climate. PHIUS+ 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 number of PHIUS Certified projects is growing exponentially. You'll find single-family homes, multi-family apartment buildings, commercial and education buildings in the PHIUS online-database of certified projects. Click on headings to sort.
PHIUS developed the Verified Window Performance Data Program to make verified building component performance data readily available to passive building practitioners. Manufacturers who have their building component performance data verified by PHIUS are able to better position their products in the marketplace by providing practitioners with the comprehensive information and climate specific recommendations they need to specify high-performance products in their projects.
PHIUS developed the Certified Building System / Panel System Program to make verified performance data for opaque building components (which may include windows and doors) readily available to passive building practitioners. The scope may comprise a full construction system, or a partial system such as a wall, roof, or foundation. Manufacturers who have their building / panel system performance data certified by PHIUS are able to better position their products in the marketplace by providing practitioners with the information they need to specify high-performance products in their projects.
The PHIUS Certified Ventilator Product Program (now in pilot phase) provides performance data needed for passive building energy modeling, and gives recognition to units that are particularly suitable.
WUFI Passive is the industry standard for assessing passive building. The following videos are narrated by Lisa White, certification manager at PHIUS.
