Maintaining the PHIUS+ Rater Credential 

PHIUS+ Raters will be issued a yearly email requesting that they submit the annual Rater agreement to PHIUS. Any questions or issues should be reported to PHIUS as soon as possible by emailing

In order to maintain/extend their standing, a Rater must complete and return the annual Rater agreement to PHIUS at the beginning of each year (January 15th). They must also maintain their status as a Certified HERS Rater in good standing with RESNET and a Quality Assurance Provider in order to be renewed. (Exception: CA and AK Raters must maintain status with their state-sponsored ratings systems and providers). 

A nominal maintenance fee will be billed on a yearly basis starting on January 15, 2018. One listing fee will be due per professional regardless of the number of certified credentials held by that professional. (For example a CPHC® who is also a Builder, will be subject to a single maintenance fee. The fee will help maintain and improve the listing database and assist in the development of the continuing education programs for all professionals.

In addition, Raters must also complete one (1) of the following four activities to maintain their status:

  1. Rate a PHIUS+ Certified Passive Building Project. In combination with the annual Rater agreement, this will extend the current expiration date to January 15th of the next year.
  2. Attend the 2-Day core conference of the PHIUS North American Passive House Conference. In combination with the annual Rater agreement, this will extend the current expiration date to January 15th of the next year.
  3. Attend the PHIUS CPHC training. In combination with the annual Rater agreement, this will extend the current expiration date to January 15th of the next year.
  4. Attend and complete the PHIUS+ Rater/Verifier Webinar and online quiz offered in December. In combination with the annual Verifier agreement, this will extend the current expiration date to January 15th of the next year.

If Rater Certification Expires

  • A Rater who fails to meet one of the above requirements by January 15th of each year will be removed from the Rater database.
  • A professional whose Rater status has expired can reactivate certification by taking and passing the current Rater exam.
