Add value to your Advanced Home Upgrade proposals by offering your customers the Home Energy Score using your existing modeling software (OptiMiser or SnuggPro). Build It Green-sponsored trainings will start in December for Advanced Home Upgrade contactors and raters!

Begin Enrollment


Enhance your business by adding the U.S. Department of Energy’s Home Energy Score to your menu of services. A Home Energy Score—like a MPG rating for a car—rates the home on a scale of 1-10, based on how much energy the home is expected to use. It can give your customers reliable information to help them save money on energy bills and live more comfortably in their homes. As energy labeling becomes more influential in the real estate market, stay ahead of the curve and offer this vital information to your clients!

Ways to use the Home Energy Score:

  • Bundle as added benefit with a standard energy audit or home inspection assessment for Advanced Home Upgrade projects
  • Encourage lead conversion to Advanced Home Upgrade projects
  • Compare pre- and post-upgrade energy efficiency improvements to show homeowners the impacts of their investment

Build It Green (BIG) is an official Home Energy Score Partner of the U.S. Department of Energy (serving California with a focus on PG&E’s service territory). That means we can assist you in completing the required FREE trainings and forms. Interested in learning more? Contact your BIG account representative

Steps to Get Started

  1. Enroll in a training class.
    • First classes begin in December 2017 with two more scheduled for 2018.

  2. View the orientation resources
  3. Review the Home Energy Score Assessor Agreement (pdf).
    • You will need to complete and sign this Agreement and return to BIG.

  4. Complete the two-part Simulation Training & Test.

    The Simulation Training and written exam require 8-12 hours of a candidate’s time to complete. It can be taken at your own pace online or during an in-person two-day Boot Camp training with Build It Green. The two-day Boot Camp training includes mentoring on your first Home Energy Score which is a requirement before you are able to score homes on your own. To find an upcoming Home Energy Score training, browse our Events Calendar

  5. Score a home with a mentor.

    Candidate Assessors must score their first home with a mentor (a Build It Green staff member). If you complete simulation training and testing online, you will need to schedule a separate Home Energy Score mentoring session with Build It Green before you are able to score homes on your own.

  6. Start scoring homes!

    After a minimal investment in time, you’ll be ready to offer Home Energy Score on your own. Scores will be uploaded to BIG along with your HPXML file for Advanced Home Upgrade applications.
