The City of Portland has adopted the new 2019 Oregon Structural Specialty Code (OSSC), which includes new energy efficiency provisions.

All building permits submitted on or after Jan. 1, 2020, must be designed to comply with the 2019 OSSC.

The 2019 OSSC includes new provisions for energy efficiency (Chapter 13 of the 2019 OSSC). The provisions are referred to as the 2019 Oregon Zero Energy Ready Commercial Code. The provisions are divided into two parts.

Part I applies to buildings constructed under the OSSC that are not Group R-2, R-3, or R-4 buildings, three stories and fewer above the finished grade. The standards are based on ASHRAE Standard 90.1-2016 which is a change from the previously adopted standard.

Additional resources about compliance and the transition to ASHRAE Standard 90.1-2016 are available from the Oregon Building Codes Division here.

The Oregon Building Codes Division also adopted Statewide Alternate Method No. 19-01 which allows use of the 2018 International Energy Conservation Code as an alternate method of compliance with Part I.

Part II applies to multi-family buildings that are Group R-2, R-3, and R-4 buildings, three stories and fewer above the finished grade designed and constructed under the OSSC. The standards are based on the 2018 International Energy Conservation Code.

In 2020, the Oregon Building Codes Division intends to update the OSSC energy provisions to ASHRAE Standard 90.1-2019 effective Oct. 1, 2020.
