Energy in Oregon

​​To build smart and conserve energy, Oregon has developed energy codes and standards for buildings.

Oregon's building codes are administered by the state Building Codes Division, including the:

  • 2021 Oregon Efficiency Specialty Code (OEESC): The 2021 OEESC, based on ASHRAE Standard 90.1-2019, became effective on April 1, 2021. This code becomes mandatory after the six-month phase-in period ends on Oct. 1, 2021. More information can be found on the Oregon Building Codes Division Energy Code Program page.
  • 2021 Oregon Residential Specialty Code (ORSC), which in Chapter 11 contains the residential building energy provisions. The 2021 ORSC became effective on April 1, 2021, and will become mandatory after a similar 6 month phase in as the commercial energy code.  During the phase-in period, use of the 2017 ORSC with the 2021 ORSC Chapter 1 or the 2021 ORSC in its entirety is permitted.
These codes outline energy efficiency requirements for Oregon buildings. The codes cover insulation, equipment, windows, lighting, and much more.

ODOE and Energy Code

The Oregon Department of Energy acts as a consultant to the Building Codes Division to evaluate and adopt the codes and amendments that will improve energy efficiency in Oregon buildings. 

ODOE also serves as a member of the  Construction Industry Energy Board and has participated with previous energy code committees offering energy efficiency guidance and recommendations.

Our team has served as a governmental voting member for development of the 
International Energy Conservation Code  (IECC), and also served directly on the 2021 IECC Commercial Code Development Committee The IECC serves as a national energy code model that cities and states may adopt or amend as appropriate. The IECC is updated on three-year cycles.​​

Additionally, ODOE participates in state and regional workgroups that may impact or focus on energy codes in Oregon, offering state-level perspectives on energy code discussions and analysis.

Oregon Energy ​Code Stakeholder Panel

In 2020, ODOE began convening convening monthly stakeholder meetings​ to discuss energy code development and code specifications and calculations, and to inform ODOE's code consultation to Oregon’s Building Codes Division. This work is part of an effort to achieve directives included in Governor Brown's Executive Order 20-04.

Built Environment Efficiency Working Group

In 2018, ODOE began convening a multi-agency working group, which is tasked to implement the directives in Governor Brown’s Executive Order No. 17-20  . The EO has directives to improve energy efficiency, boost electric vehicle adoption, and support actions to reduce greenhouse gas emissions in the state.
