The files on this page contain commercial reference building models for existing buildings constructed before 1980, organized by building type and location. These U.S. Department of Energy (DOE) reference buildings are complete descriptions for whole building energy analysis. You can also return to a summary of building types and climate zones and information about other building vintages.
These files are updated regularly. There are two versions of these files on this page. Version 1.3_5.0 was updated September 27, 2010 and Version 1.4_7.2 was updated November 13, 2012.
You can also view related resources:
- an archive of past reference buildings files
- a ZIP file containing the TMY2 weather data that were used to generate the following reference buildings
- a document identifying the changes made from the previous version.
- a summary of the annual energy use per square foot for each building in each climate is available.
The DOE reference buildings, in ZIP files, are by building type and climate zone. The ZIP files contain the following:
- An EnergyPlus software input file (.idf)
- An html file showing the results from the EnergyPlus simulation (.html)
- For ZIP files by building type, a spreadsheet that summarizes the inputs and results for each location (.xlsx)
- For ZIP files by climate zone, the EnergyPlus TMY2 weather file (.epw).
- For version 1.4, only the IDF file is included.
Reference Buildings by Building Type
In addition to the ZIP file for each building type, you can directly view the "scorecard" spreadsheet that summarizes the inputs and results for each location. This Microsoft Excel spreadsheet is also included in the ZIP file. For version 1.4, only the IDF file is included.
