Step 1- Credential Requirements
Hold a credential in one of these certifications at a minimum
Residential Energy Services Network (RESNET) HERS Rater
Building Performance Institute (BPI) Building Science Principles Certificate of Knowledge
Certified GreenHome Associate – CGHA or CGHP
National Association of the Remodeling Industry (NARI) Green Certified Professional, Certified Remodeler, or Master Certified Remodeler
International Association of Certified Home Inspectors (InterNACHI) Home Energy Inspector
American Society of Home Inspectors (ASHI) ASHI Inspector or Certified Inspector
National Association of Home Inspectors (NAHI) Certified Real Estate Inspector
North American Technician Excellence (NATE) Air Conditioning/Heat Pumps, Gas/Oil Heating, or Gas/Oil Hydronics
*Minimum credential is not required if the interested Assessor already holds a higher level certification from one of the credentialing organizations listed.
Step 2 - Pass a free online test
Interested Assessors with the necessary credentials must also pass a two-part test in order to access the Home Energy Scoring Tool. The test includes practical and written portions. The practical exam takes place in the Home Energy Score Simulation Training (the Sim), a 3-D simulation environment.
HOME ENERGY SCORE SIMULATION TRAINING AND TEST (THE SIM)
The Sim models the data collection process in several sample homes. Before taking the test, candidates have access to training tools including practice houses in the Sim. Candidate Assessors must score an 80 or better on three “Challenge/Practice” homes and a 90 or better on two test homes. Candidates must score an 80 or better on the written portion of the exam which consists of 20 questions covering the Home Energy Score program. A video demonstrating the Sim is available from Interplay Learning, the technology company that developed the Sim for DOE.
There is no limit to how many times you can take the test and it is open book / open note.
Step 3 - Mentorship
Once you have passed the test and are qualified to score homes, you must be accompanied by a “mentor” (a highly experienced professional) during their first home walk through. There may be opportunities to mentor on multiple projects and there could be funding to pay for training. Please inquire. There may also be a fee for mentorship, all of this contingent on funding and location or willingness to travel.
Step 4 - Quality Assurance & Upkeep
First, you up keep your credential and you will be audited to ensure it is active. These assessments may qualify to fulfill your credential upkeep duties.
Each home you score and submit will cost $25.00, this will help fund a quality assurance retest of 5% of all of your audits. Homeowners may be contacted to request a re-inspection follow up, please let them know they may be contacted for a request.
There are no cost for submittals on GreenStar registered projects.
Existing Assessors who have qualified within the last four months or have kept their status active by scoring houses within the last four months will not need to requalify. Those who have not stayed active will need to work through with GHI to take a brief online Assessor refresher course and test, at no cost.
HES & GreenStar Homes Certification
While not required, we highly encourage all the GreenStar Home Raters to utilize the Home Energy Score for their projects. The Home Energy Score will be a foundational way to make better decisions in GreenStar home renovations and additions as well as be a basis for many of the energy points. HES assessors also prequalify to be GreenStar Raters. GreenStar Professionals can also use this tool to do test in or guide design but it must be assessed by a 3rd party rater at the end of project.
What homes qualify?
- Existing Homes
- Planned renovations or additions
- New Construction
- Only Single family attached or detached
- No multifamily projects with separate stacked living units are allowed (though exceptions may apply)
Can I work with more than 1 parner?
You may be interested in working with different partners based on the markets they serve, funding and/or incentives available to do assessments. We encourage you to partner with others as needed. It only requires that you have a separate email account for each partner.
