Download the Roadmap or follow the step outlined here.

STEP 1. Obtain and verify qualifying US DOE credentials.

STEP 2. Complete Home Energy Score Simulation training.

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

STEP 4. Complete the home energy assessor participation agreement

STEP 5. Attend mandatory orientation.

STEP 6. Successfully complete required mentoring session.

Estimated time frame: varies by training provider

STEP 2: 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: Earth Advantage will email you the approved ODOE – Home Energy Assessor Training Certification Form from Step 1.

STEP 6: As required by US DOE, you must schedule and score your first home accompanied by a mentor designated by Earth Advantage (unless you already completed this as part of a guided in-person simulation training – see Step 3).

Estimated cost: $150

Estimated time frame: 2 hr. field visit + energy modeling

STEP 7: You are now authorized to conduct City of Portland Home Energy Score assessments and generate the home energy report!

Estimated cost: $25/score quality assurance fee

Estimated time frame: 1.5 hr./home - field assessment, energy modeling, home energy report generation

Program Roles
