Save Energy

Investing in energy-efficient homes helps Oregonians save money now and supports a better energy future.
Home Energy Score SampleHome Energy Performance Score systems help homeowners and homebuyers better understand a home's energy use, and how even small improvements can make a big difference in energy savings.

A certified professional evaluates a home's performance and issues a score, similar to the bright yellow Energy Guide label found on home appliances. The professional will look for air leaks, check insulation levels, inspect windows and doors, make sure heating and cooling systems are well-maintained, check lighting, and more. 


Home Energy Performance Scores in Oregon​

The Oregon Department of Energy has developed a standard home energy performance score system to illustrate a home's energy efficiency and energy use.

Oregon Administrative Rules outline the requirements for residential and commercial energy performance scores. The rules also establish training requirements for licensed home energy assessors and define requirements for score systems.

Oregonians will benefit from the streamlined process with consistent measurements across home energy performance score systems. A stakeholder panel is helping inform the voluntary program. 


Approved Oregon Home Energy Performance Score Systems

Currently, Oregon has three approved home energy performance score systems:
Become an Approved Score System

Businesses and other entities seeking approval for a home energy performance score system will need to submit an application to ODOE.

The Home Energy Performance Score Stakeholder Panel will review applications and recommend approval or denial to ODOE's director. ODOE staff are available to help businesses improve or streamline proposed systems. 


Home Energy Score Assessors
 ​​​
Find an Assessor

Home energy scores are required within the city of Portland limits. Visit the City of Portland's website to learn more about its home energy score program, and find a list of qualified assessors with Earth Advantage​.

Outside Portland, home energy scores are voluntary. The Oregon Department of Energy is working on developing a list of approved assessors who can conduct home energy score assessments outside Portland.

Apply to Become a Certified Home Energy Assessor

​Certified home energy assessors can assign a home energy performance score to residential buildings. 

Assessors must complete training from an Oregon Department of Energy-approved source. See the Home Energy Assessor Training Certification Form​ for a list of approved training courses. 

The step-by-step process to become a certified energy assessor and related application materials are available on the CCB website

Deactivation or Transfer of Home Energy Assessor Certification

Oregon administrative rules require each home energy assessor to hold, or work under, a current CCB license and home energy assessor certificate. If any of the following occur, the home energy assessor certification associated with that license will become deactivated and scoring software accounts will become deactivated:

  • CCB license expires
  • Home energy assessor certification expires
  • Home energy assessor disengages employment with an organization holding an active CCB license 

Each home energy assessor is required to notify the Oregon Department of Energy and program implementation staff if there has been a change in home energy assessor licensing status.

A home energy assessor certification may be reinstated, or a new certification produced, once the individual has fulfilled proper CCB licensing and certification steps or is employed under a new company with a valid license. Steps to obtain new licensing and changes in licensing are available on the CCB website . ​
