The Industry Services Division 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.
Rental Weatherization Energy Efficiency is a separate program. The division also maintains standards for energy efficiency of existing rental units. Certificates of compliance are issued by state-certified private inspectors.
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 & exterior general lighting requirements ONLY. (HVAC portions of the program are not acceptable since the information is required to be on the associated plans.) 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 options of “2009 IECC” unless 2009 IECC section 501.2 is applied which would then allow the application of ASHRAE 90.1-2007, in which case the option “90.1 (2007) Standard” must be used.
REScheck, another software application from DOE, is now used for demonstrating building envelope compliance for low-rise multi-family (3 dwellings or more 3 stories or less above grade). (Within REScheck, a user is required to choose the code option of “2009 IECC” as the code type to demonstrate building envelope compliance.)
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
The department 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.
