Code Amendments: Washington

  • Beneficial Mass Wall Credits Will Remain in Washington Energy Codes
    If you are designing a gymnasium, big-box retail, or one of several other building types, you can still utilize integral-insulated exposed single-wythe concrete masonry (CMU) walls for code compliance. This cost-effective wall system remains a prescriptive path design option in the latest Washington and Oregon energy codes.
