Upcoming Updates

1-100 ENERGY STAR score for U.S. medical office buildings to be updated February 7, 2022

Medical BuildingEPA will roll out an updated 1-100 ENERGY STAR score for U.S. medical office buildings on February 7, 2022. The updated score will provide building owners and managers with a more accurate picture of how their building’s energy use compares to similar facilities across the country. In addition, after an eight-year hiatus, U.S. medical office buildings will once again be eligible to earn EPA’s ENERGY STAR certification for superior energy performance.

About the New Score

The updated ENERGY STAR score is based on 2015 data collected by the American Society for Health Care Engineering and will replace the existing score which is based on a dataset from 1999. A score of 50 on EPA’s 1 – 100 scale indicates that a building has average energy performance, while a score of 75 indicates that a building outperforms 75% of similar buildings and is therefore eligible for ENERGY STAR certification.

In 2014, due to the age of the dataset on which the existing score was based, EPA suspended certification for medical office buildings. With the availability of much more recent data in the 2015 dataset, EPA is able to update the model that powers the ENERGY STAR score and once again support ENERGY STAR certification for the top 25% of all U.S. medical office buildings.

What You Need to Do

  1. Review your Number of Surgical Operating Beds and Number of MRI Machines. Both will now affect your score, so you want to make sure they’re correct. If you don’t have anything filled in, we’ll default both values to zero (0).
  2. Keep a record of your previous scores. Once the score model is updated, you will automatically see a new score in your Portfolio Manager account, even for historical time periods. (We update the historical scores so you will be able to accurately compare your buildings’ energy performance over time. Otherwise, you would not be comparing "apples to apples" in your metrics from year to year.) To save your old scores, follow our instructions to run a “Performance Highlights” report or create a custom report, then download and save those reports.

How Will Your Score Change?

The 1-100 ENERGY STAR score is a comparative metric, rating your building against similar buildings nationwide. The current score is based on a national survey of medical office buildings conducted in 1999. The new scores are based on a 2015 survey to reflect the most recent data available—both in terms of energy performance, but also in terms of modern equipment and operations. For example, the new score will adjust for MRI machines and surgical operating beds—equipment that was not factored into the current score.

We can’t predict how your individual score will change. On average, across all medical office buildings in Portfolio Manager, we are expecting a slight increase in ENERGY STAR scores, particularly those with greater quantities of MRI machines and surgical operating beds. However, it is possible that some buildings will see their scores decrease when compared to the newer 2015 data set.

Limited-Time Opportunity to Apply for 2021 ENERGY STAR Certification

From February 7 - March 7, medical office buildings that receive a post-update ENERGY STAR score of 75 or higher will be able to have their certification be labeled as 2021 or 2022. It is possible to earn certification for both years, thanks to our flexible rules around re-certification. As long as you apply for 2021 certification using a Period Ending Date (PED) of Oct, Nov, or Dec 2021, then you will be able to apply for 2022 certification using any PED after July 2022.

Data collection underway to develop a 1-100 ENERGY STAR score for U.S. convenience stores

Represented by the National Association of Convenience Stores (NACS), the U.S. convenience store industry includes about 152,720 retail stores, owned by about 1,500 retailers, and is serviced by about 1,600 suppliers. NACS conducted a survey to gather data on the energy use and operations of convenience stores and has shared the data collected with EPA. EPA is now analyzing the data and will be developing a new 1-100 ENERGY STAR score and certification for convenience stores, with an expected launch in 2023. 

Data collection planned for U.S. vehicle dealerships

Represented by the National Automobile Dealers Association (NADA), the U.S. vehicle dealership industry includes some 16,500 new car and truck dealerships with 32,500 brand franchises. In the spring and summer of 2021, NADA conducted a survey to gather data on the energy use and operations of U.S. vehicle dealerships and has shared the data  with EPA. EPA is now analyzing the data and will be developing a new 1-100 ENERGY STAR score and certification for U.S. vehicle dealerships, with an expected launch in 2023. 

Past Updates

2021 Update of the 1-100 ENERGY STAR Score for U.S. Hospitals

In February 2021, EPA updated the 1-100 ENERGY STAR score for U.S. hospitals to reflect new market data from 2015 collected by the American Society for Health Care Engineering (replacing the prior data from 2008). This update also included the addition of heating degree days (HDD) to the scoring model.  While the score change for each hospital will depend on a number of factors unique to that property, the average score change for U.S. hospitals in Portfolio Manager was an increase of 1.4 points, and ~95% of hospitals experienced score changes ranging from -2 to +5 points.

2018 updates to ENERGY STAR® metrics

In August 2018, EPA updated performance metrics for U.S. buildings in ENERGY STAR Portfolio Manager® based on the most recent market data available. This update is part of EPA’s standard process to keep ENERGY STAR metrics as current as possible, and reflective of current market performance. At this time, the 1–100 ENERGY STAR scores and other source energy metrics for were updated for U.S. buildings benchmarking in Portfolio Manager across all time periods to reflect the latest performance metrics.

This update was followed by a score review period for U.S. K-12 schools, worship facilities, warehouse properties, hotels, offices, retail stores, and supermarkets, during which EPA engaged industry to get feedback, conduct additional analysis, and ensure the score models deliver metrics that support organizations' energy efficiency goals. Certification was temporarily suspended and resumed on a rolling basis as EPA finalized its analysis for each score model. In July 2019, EPA concluded the score review period and certification resumed for all eligible U.S. building types.

Note that none of these changes impacted Canadian buildings.
