Oregon Building Performance Standard ASHRAE 100

Oregon Building Performance Standard (ASHRAE 100) establishes energy performance requirements for existing commercial buildings, advancing the state’s sustainability goals. Mandated by the Oregon Department of Energy, this policy aligns with ANSI/ASHRAE/IES Standard 100-2024, requiring building owners to implement energy efficiency measures, conduct audits, and meet greenhouse gas reduction targets. Covering Tier 1 and Tier 2 buildings, the standard outlines performance benchmarks, compliance schedules, and decarbonization strategies. To avoid penalties, building owners must submit energy reports and adopt energy-saving upgrades. This initiative is designed to drive significant emission reductions, lower energy consumption, and support long-term sustainable development.
