Building Energy Models for Commercial Buildings Based on CBECS Data

BEM

As an outcome of ASHRAE RP-1771, we have developedbuilding energymodels based on Commercial Buildings Energy Consumption Survey (CBECS) data to support the development of the ASHRAE building energy quotient (bEQ) standard. These building energymodels 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 energymodels are developed based on the 2003 CBECS data, whichinclude 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).
