The commercial IECC prototype building models were developed by Pacific Northwest National Laboratory in support of the U.S. Department of Energy's (DOE's) Building Energy Codes Program. These prototype buildings were derived from DOE's Commercial Reference Building Models. The prototype models include 16 building types in 19 climate locations for for recent editions of the IECC. Also included is a scorecard for each prototype building. The scorecard is a spreadsheet that summarizes the building descriptions, thermal zone internal loads, schedules and other key modeling input information.

The State of Michigan is in the process of updating its current state residential energy code, which is an amended version of the 2015 International Energy Conservation Code (IECC) to the 2021 IECC. The Michigan Bureau of Construction Codes, a bureau within Licensing and Regulatory Affairs (LARA), requested a cost-effectiveness analysis, that considers the Michigan Stille-Derossett-Hale Single State Construction Code Act,1 comparing the current state residential energy code to the unamended 2021 IECC.

The resulting analysis shows that a home designed to comply with the residential provisions of the 2021 IECC would yield short-term and long-term consumer benefits compared to a home built to the Michigan-amended 2015 IECC.

The International Energy Conservation Code (IECC) prototype building models (prototype models) were developed by Pacific Northwest National Laboratory (PNNL), in support of DOE's Building Energy Codes Program (BECP), to simulate energy savings associated with changes in energy codes and standards. For residential buildings, PNNL utilized two base prototypes to simulate both Single-family detached house, and Multi-family low-rise apartment building types. Energy models for the recent versions of the IECC are available for each climate.
