As an outcome of ASHRAE RP-1771, we have developed building energy models based on Commercial Buildings Energy Consumption Survey (CBECS) data to supBEMport the development of the ASHRAE building energy quotient (bEQ) standard. These building energy models can be used as a starting point to reconcile the differences between the empirical and modeled baselines for energy performance comparison for new and existing commercial buildings, allowing seamless translation of building energy performance metrics among LEED, Standard 90.1, Standard 189.1, Standard 100, and the bEQ As Designed and In Operation ratings. 

These building energy models are developed based on the 2003 CBECS data, which include 18 commercial building types in two vintages (pre-1980 and post-1980) in 15 climate locations in the U.S. This results in an overall set of 540 total building energy models (EnergyPlus™ Version 9.0 for Supermarket; EnergyPlus™ Version 8.7 for the other building types).


Current version (V2.0) was released on 3/11/2022. See release history for previous releases.
