Updates to ENERGY STAR scores with CBECS data

For most types of commercial buildings, the 1 – 100 ENERGY STAR score is based on the Commercial Buildings Energy Consumption Survey (CBECS), which is conducted about once every four years by the Energy Information Administration (EIA). New CBECS data will be available in late 2015, when EIA releases the results of its 2012 survey.

To learn how EPA will use this information, view the May 2014 recorded webinar, Planning for Updates to the 1 to 100 ENERGY STAR Score with 2012 CBECS Data. EPA plans to host a series of additional webinars, starting in Fall 2014, to keep you informed and gather your input throughout the process of updating the 1 – 100 ENERGY STAR scores. All webinars will be publicly announced, recorded, and available to watch at any time on the ENERGY STAR training portal.

The table below provides a quick overview of each 1-100 ENERGY STAR score’s data source and most recent update. Most of the scores rely on data from CBECS. EIA was unable to publish the 2007 CBECS; therefore, many of the scores still rely on data from prior CBECS. Once EPA has access to the CBECS 2012 data, we will conduct extensive analyses to begin the process of updating our existing ENERGY STAR scores as well as develop scores for additional types of buildings.
