Northwest 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. 

In Washington state both mass wall U-factor requirements of 0.104 and the single-wythe concrete masonry exception will remain in the 2021 state energy code that runs until July 1, 2026.
