16 Wisconsin Code Creation Process Per Legislature: Wisconsin must adopt new ICC Suite of Codes within 3 years of publication Safety & Buildings Division does background work to compare existing code to proposed new code A C Code Advisory Panel is selected to advise the Division on each portion of the code (IECC for example). This group is made up of representatives from Municipal Inspectors, ASHRAE, AIA, Assn of General Contractors, SMACNA, and Other stakeholders.

17 Wisconsin Code Creation Process Following a series of Code Council meetings, a Draft is published The Secretary of the Dept Reviews and Approves the Draft Public Hearings are held and all comments require response Final Approval from The Secretary Final Draft is submitted to the legislature for Approval This Entire Process Generally takes 2 years

18 Wisconsin Codes Future Commercial Buildings: ASHRAE /IECC 2009 has passed through Public Hearings and has been sent to the legislature. Enforcement anticipate by April 1, 2011 Residential Buildings: Code Advisory Council is setting up meetings to update the current Comm 22 (equivalent to IECC 2006) to meet the new Energy Efficiency Standards of IECC For various reasons, it is unlikely that the current One & Two Family Dwelling code will be tottally replaced with the IRC, althiugh the requirements are almost identical.
