Which CBECS data is Portfolio Manager using? Follow

As of August 26, 2018, EPA is using the 2012 Commercial Building Energy Consumption Survey (CBECS) data to create most of the 1-100 ENERGY STAR scores in Portfolio Manager.

For details on this and future score changes, please visit: www.energystar.gov/scoreupdates

Until the next CBECS data set is available (the 2018 survey is currently underway), users of the ENERGY STAR Score should have confidence that:

  • The ENERGY STAR Score remains the best representation of commercial building energy performance in the market
  • CBECS 2012 continues to be the best source of industry data
  • EPA will work to develop alternative methodologies if deemed necessary or beneficial. Currently, five of the property types eligible to receive an ENERGY STAR score in Portfolio Manager were developed using non-CBECS data. The five property types are: Data Centers, Hospitals, Multifamily Housing, Senior Care Facilities, and Wastewater Treatment Plants.
