Rater Training Earns


Here’s a great way to expand your business and move into the passive house market

PHIUS is seeking experienced HERS Raters to complete a two day course in order to become qualified to conduct on-site quality assurance for the PHIUS+ program. Passive buildings are some of the most energy efficient buildings in the world, with space conditioning energy savings of up to 90% compared to standard new construction. 

The PHIUS+ certification program for North American Passive Houses 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 checks, specific to the PHIUS+ program.

The two-day course includes one day of classroom work with a second day spent in the field, demonstrating advanced testing and inspection protocols for the PHIUS+ program. The course concludes on the second day with an exam. Successfully completing the course and exam qualifies a Rater to become a PHIUS+ Rater and earns the Rater fourteen (14) RESNET professional development credits. Application to the program is required.

(Certified Passive House Consultants are eligible to become PHIUS+ raters, but once qualified, cannot rate their own projects.)
