The files on this page contain commercial reference building models for new construction, 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 and comply with ANSI/ASHRAE/IESNA Standard 90.1-2004. For more information about standards, visit the ASHRAE Web site. 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.
