Commercial Reference Buildings

From Open Energy Information

DOE developed Commercial Reference Buildings which provide descriptions for whole building analysis using EnergyPlus. There are 16 building types and three categories that apply to all building types. The commercial reference buildings were developed across 16 reference locations.

Building Types

DOE developed 16 Commercial Reference Building Types[1] , which represent approximately 70% of the commercial buildings in the U.S. [2]. Whole building energy analysis data (developed using EnergyPlus simulation software) is available for each construction category (listed below) and each building type.
