Oregon Residential Specialty Code: Energy Efficiency Analysis

The Northwest Energy Efficiency Alliance (NEEA) contracted with Ecotope, Inc. to conduct the 2017 Oregon Residential Specialty Code (ORSC) Energy Efficiency Analysis. The study was designed to evaluate energy performance for newly constructed homes to inform the future Oregon residential energy code and support the Governor of Oregon’s Executive Order in achieving the U.S. Department of Energy’s Zero Energy Ready (DOEZER) homes by 2023.

This study provides a snapshot of annual energy consumption for homes to comply with the 2017 ORSC and meet the DOEZER specifications. The analysis also shows alternative pathways to achieve DOEZER equivalent energy savings by 2023. The report documents least cost pathways and maximum energy savings pathways which can be considered to meet the DOEZER Equivalent target. Finally, the report provides recommendations of combination of measures which can be considered in the future code development in Oregon.
