Washington State Energy Code (WSEC) Commercial Provisions – Compliance Forms and Educational Resources
NEEC provides technical assistance, tools and educational resources for the Commercial Provisions of the WSEC. Commercial Provisions apply to all commercial occupancies, Group R-2 and R-3 occupancies greater than 3 stories above grade, and Group R-1 of all building heights. Many building jurisdictions require that Compliance Forms accompany project permit submittals as a means of documenting the method of compliance of all applicable commercial provisions. Educational resources include classroom trainings, webinars, fact sheets and other informational tools.
NOTE: The 2015 WSEC 2nd Edition has been posted by the WA State Building Code Council (SBCC). This edition is effective October 1, 2017.
