Upcoming Updates

1-100 ENERGY STAR score for U.S. medical office buildings tentatively set to be updated in late 2021

Medical BuildingEPA is in the process of analyzing survey data and developing an updated 1-100 ENERGY STAR score for U.S. medical office buildings. The goal of the score update will be to provide a more timely comparison for building operators and to reinstate ENERGY STAR certification for medical office buildings.

The current model compares today’s hospitals’ energy use and operations against the 1999 Commercial Building Energy Consumption Survey (CBECS) dataset. Due to the age of this model, EPA made the decision to suspend certification for medical office buildings effective on January 1, 2014. This update will provide a comparison based on 2015 data collected by the American Society for Health Care Engineering (ASHE).

The update is tentatively scheduled to take place in late 2021. EPA will provide further updates in the coming months, and will hold a webinar to share details of the updated model prior to its release.

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 is conducting a survey to gather data on the energy use and operations of convenience stores and intends to share the data collected with EPA. EPA will then analyze the data to determine if a new 1-100 ENERGY STAR score and certification can be developed for convenience stores. The NACS data collection survey is expected to be completed sometime in the spring of 2021, followed by analysis to determine if a new score can be developed based on survey responses.

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. NADA plans to undertake a data collection effort during the spring and summer of 2021. If sufficient data is collected, NADA will provide that data to EPA for analysis and to determine if a new 1-100 ENERGY STAR score and certification can be developed for U.S. vehicle dealerships.

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.
