You are here

The files on this page contain commercial reference building models for existing buildings constructed in or after 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:

  • For ZIP files by building type, a "scorecard" 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.
