Washington State Energy Code
Thurston County Enforces the 2015 Washington State Energy Code. Unlike building (construction) codes -- which are based on the International Building Code -- the Washington State Energy Code is a state-written, state-specific code. Residential and commercial construction in unincorporated Thurston County must meet the requirements of this code.
For Microsoft Excel-based compliance worksheets (residential), visit the Washington State University Extension Energy Program. The WSU website also offers energy code training materials and reference publications.
To read the code, visit the State Building Code Council's website and scroll down to "Energy Code"
