The Division of Industry Services (DIS) sets standards for energy efficiency on buildings in Wisconsin. See the
Commercial Building and
One- and Two- Family Dwelling programs for enforcement, education, and consultation details for those building types.
Questions regarding the energy codes can be sent to DspsSbBuildingTech@wisconsin.gov.

Can mercury containing devices be sold in Wisconsin?
No. This is based on Wisconsin Law as published under 2009 Act 44.
Commercial Building Code
COMcheck is Federal Department of Energy (DOE) software approved in Wisconsin for demonstrating compliance with commercial building envelope requirements and interior and exterior general lighting requirements ONLY (HVAC portions of the program are not acceptable). COMcheck can be used for commercial buildings or high-rise (>3 stories) multi-family buildings. Within COMcheck, a user is required to choose the code option of "2015 IECC" unless 2015 IECC section C401.2 Item 1 is applied which would then allow the application of ASHRAE 90.1-2013, in which case the option "90.1 (2013) Standard" must be used. Although IECC C406 is NOT adopted for use in Wisconsin, COMcheck users are reminded that they must indicate an "Additional Efficiency Package Option" on the screen in order for the COMcheck programming to evaluate the entered data.
Uniform Dwelling Code
REScheck is a software application that has been created by the Federal Department of Energy for demonstrating compliance with building envelope requirements of various State building codes. As of January 1, 2016, a user is required to select “2009 IECC” in order to demonstrate compliance with the requirements listed in the Wisconsin Uniform Dwelling Code (UDC) for use with one and two –family dwellings. Additionally, the user must then also indicate that the calculations are for 1- and 2- family dwellings. REScheck is available for download
DIS has requested that the software developer modify REScheck so that heat loss calculations can also be addressed, as was the case prior to January 1, 2016. Please feel free to return to this web page at a future time so as to view the status of that request.
