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 2006, 2009 and 2012 versions of the IECC are available for each state.
Complete IECC Prototype Building Model packages include files for every state by IECC version.
Each ZIP file includes EnergyPlus model input files (.idf) and corresponding output files (.html).
Note: each of these files are over 100 MB in size; download times may vary.
