The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Last DSIRE Review: 10/05/2012
Program Overview:
State: Wisconsin
Incentive Type: Building Energy Code
Eligible Efficiency Technologies: Comprehensive Measures/Whole Building
Applicable Sectors: Commercial, Residential
Residential Code:COMM 22 of the state-developed Uniform Dwelling Code (UDC) is applicable to 1 & 2 family dwellings and incorporates the 2006 IECC with state amendments. (REScheck may be used when the code assignment is indicated to be "Wisconsin" in REScheck). Multi-family dwellings also comply with these codes in addition to specific changes from the COMM 63 guidelines based on 2009 IECC implemented on September 1, 2011.
Commercial Code:Comm 61-66 of the state-developed Uniform Dwelling Code (UDC) is mandatory statewide. It is applicable to nonresidential dwellings and incorporates the 2009 IECC including additional air barrier requirements. COMcheck can be used to show compliance.
Code Change Cycle:Codes are updated automatically and on an ongoing basis through various citizen advisory project committees and the Wisconsin Building Code Advisory Review Board. Most recent update to COMM 63 codes effective September 1, 2011.

Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

In March 2006, SB 459 was enacted to promote renewable energy and update the state's building energy codes.

The law required the Department of Commerce (DOC) to create codes for energy conservation in public buildings and places of employment and to review that code. In conducting the review, the DOC must consider incorporating into the Energy Conservation Code design requirements from the most current national energy efficiency design standards that are generally acceptable and used by engineers and the construction industry. Unlike the previous law, SB 459 refers to the International Energy Conservation Code instead of the 1989 version of a standard adopted by ASHRAE. The bill also changes the five-year revision requirement to a three-year requirement.

The state of Wisconsin implemented many changes to its Uniform Dwelling Code (UDC) for 1&2-family dwellings. Among them, changes were made to COMM 22 (beginning on page 66/102) of the UDC to incorporate the 2006 IECC with Wisconsin amendments. The 2009 IECC code, with some augmentations for commercial construction was officially implemented on September 1, 2011.
