This presentation will cover changes to commercial energy codes for buildings in Oregon and Washington. In 2019, Oregon underwent a major shift from I-code to ASHRAE Standard 90.1-2016 as its commercial energy code, which impacted the areas of envelope, lighting, mechanical systems, and building commissioning. Recently in 2021, Oregon has adopted the next version of the ASHRAE standard, ASHRAE 90.1-2019, which will become fully effective October 1. The Washington changes, effective as of Feb. 1, 2021, will require a calculation of HVAC system efficiency and will impact the areas of lighting as well. Both codes have adopted a whole-building energy performance compliance path. Also mentioned will be Washington’s new Clean Building Bill, and what that legislation means for facilities. Find out what you need to know about these energy codes that apply to newly constructed buildings, additions, and alterations and existing building energy performance.
