What is a Rating Field Inspector (RFI)?

An individual certified by a Rating Quality Assurance Provider to conduct field inspections for home energy ratings. A Rating Field Inspector (RFI), under the direct supervision of a certified Home Energy Rater, may conduct the inspections and necessary basic performance tests (air tightness and duct leakage) to produce a home energy rating. This certification requires the ability to identify and quantify building components and systems.

How to become a Rating Field Inspector (RFI)?

Complete five (5) probationary ratings with a Mentor using the RESNET RFI Field Evaluation Form. At least one (1) rating must be a rough in inspection and one (1) must be a final inspection. Ten (10) supporting photos must be taken at each home and kept by the Rating QA Provider for a minimum of three years.

All required RFI tasks during the final evaluation must be successfully completed in one exam period.

    • Ten (10) photos for each home are to be kept by the Rating Provider for each candidate.  (See photo documentation guidelines below.)
   Step 3
  • Qualified Assessors should record on the provided RFI Field Evaluations Form ONEfinal graded field evaluation home per candidate.
    • Final graded field evaluations are conducted after the five mentored ratings are completed and must be completed in one exam period.
    • Candidate final evaluations must list “satisfactory” (100%) on all features that are present.
    • Assessors must sign the candidate’s assessment form.
