Find a PHIUS+ Rater

The PHIUS+ certification program for North American passive buildings combines extensive design review with a rigorous on-site quality assurance program. PHIUS+ aligns with the quality assurance protocols of Energy Star 3.0 and DOE Challenge Home, while including additional tests and protocols specific to the PHIUS+ passive building certification program.

PHIUS+ Raters are RESNET raters in good standing who have successfully completed PHIUS passive house rater training. Only PHIUS+ Raters have the training to perform PHIUS+ certification, assign an accurate HERS Index, and to perform RESNET-approved quality assurance and quality control on passive house projects. Raters complete two-days of rigorous hands-on training, including one day of classroom work with a second day spent in the field to learn advanced testing and inspection protocols for the PHIUS+ program. To ensure third-party QA/QC standards are upheld, PHIUS+ Raters who have also earned the Certified Passive House Consultant (CPHC®) credential cannot rate their own projects.
