Energy Modeling & Compliance in Siletz, OR

Energy Modeling & Compliance in Oregon: what governs your project

Oregon enforces its own Oregon Energy Efficiency Specialty Code (OEESC), based on ASHRAE 90.1-2019 and effective since 2021 — a state-written code that diverges from the model IECC in meaningful ways — with the Oregon Commercial Reach Code (2025) available as the above-code stretch option. Energy Trust of Oregon incentives reward efficient commercial construction. Torch models to the OEESC's actual provisions, documents compliance for Oregon's reviewers, and aligns the analysis with incentive requirements.

Permitting & plan check

Portland's Bureau of Development Services runs a well-established electronic plan review process; other large cities like Eugene, Salem, and Bend operate their own portals. Many smaller cities and counties rely on third-party review agencies. Land-use approvals often run on a separate track from building permits in Oregon jurisdictions.
