In August 2018 the EPA updated the ENERGY STAR® performance metrics in Portfolio Manager® to reflect the most recent market data available. The data showed that energy use and business practices in U.S. commercial buildings have changed dramatically since the EPA last updated the ENERGY STAR® score models in 2007. The average ENERGY STAR® score was reduced by 10 points from the 2007 office model to the August 2018 office model.

Based upon feedback EPA received from various commercial office properties in September 2018, companies with portfolios spanning different regions of the U.S. reported a trend of greater score reductions in colder climates. EPA's analysis found that an adjustment was needed to account for energy used for heating. The analysis found that an adjustment is needed to account for energy used for heating. Therefore, EPA has reintroduced HDD (heating degree days) into the scoring process, which results in more equitable scores for office properties in all climates.


Office building scores, including adjustments for HDD where applicable, became live in Portfolio Manager® on 7/22/19. You may see score increases for some office buildings located in colder climates. On 7/31/19 EPA plans to resume ENERGY STAR® certification for office buildings.


The Awards Committee voted that in the 2020 TOBY cycle each building's State of Energy Performance ENERGY STAR® score will be reduced by 10 points. Over the next year we will monitor ENERGY STAR Portfolio Manager®, as well as applicant scores, closely and will discuss whether to make adjustments to the TOBY scoring model for future awards cycles.


                                2020 TOBY Cycle

  • ENERGY STAR® Score: <65:       3 points
  • ENERGY STAR® Score: 65-74:    4 points
  • ENERGY STAR® Score: 75-84:    5 points
