We recommend contacting a PHIUS+ Rater/Verifier as soon as certification becomes a goal for the project, and incorporate them into the project team early on. PHIUS asks that you hire a Rater/Verifier when you submit a project contract to PHIUS at the start of Certification.
- Before pre-certification is awarded to a project, PHIUS requires a letter of intent from the PHIUS+ Rater on the project, stating they have been hired to complete the on-site verification process.
PHIUS acknowledges that the addition of this component to our certification does raise fees. However, we also feel strongly that it helps create higher quality buildings.
PHIUS has not set a fee structure for the PHIUS+ Raters/Verifiers to charge for their services. For a single family home, expect 20 hours of work at the PHIUS+ Rater/Verifier’s hourly rate (typically $75-$125 per hour depending on market). This does assume a relatively straightforward process. Significant problems could result in more time needed, but simple homes may expect less time for completion.
Be aware that travel can significantly affect the quote the project team receives from a PHIUS+ Rater/Verifier.
3.7.1 Non-certified Inspectors
See Appendix E Section 2.3 below.
3.7.2 Typical Site Visits for the Rater/Verifier:
- Sub-slab insulation check.
- Preliminary blower door test.
- Insulation quality check.
- Final blower door, ventilation commissioning, final Quality Assurance Workbook.
Coordination of the site visits and design review by the PHIUS+ Rater/Verifier should occur between the Rater/Verifier and the project team. The number of site visits is up to the Rater/Verifier. If they are close by, we encourage them to see the slab insulation in person. However, they can choose just to collect photos. Preliminary blower door testing is, strictly speaking, optional, however, it is strongly encouraged.
