Roadmap to becoming a Home Energy Assessor

Outlined below are the required steps to become an authorized Home Energy Assessor with the City of Portland Home Energy Score program.

This entire process is estimated to take a minimum of four weeks and $625 to complete.

To complete the process, you must hold an Oregon CCB license for residential contractor, residential specialty contractor license, or residential restricted Home Energy Performance Score Contractor. Download the Roadmap or follow the step outlined here.

STEP 2. Complete Home Energy Score Simulation training.

US DOE will email you access to the Simulation Training. This is a self-paced training process where you will conduct virtual home walk-throughs designed to show a variety of situations you might encounter, in order to learn how to produce an accurate home energy score. Once complete, US DOE will email you to confirm you passed a series of test homes and a multiple choice exam.

Note: For additional assistance, you can optionally attend guided trainings through Earth Advantage. Recommended for those without experience in on-line simulation training modules.

Estimated cost: Free (unguided) or $100 (guided)

Estimated time frame: 12+ hours, usually over a few weeks (unguided) or 12-16 hours over 1.5 to 2 days (guided)

STEP 3. Obtain and verify home energy assessor CCB certificate.
