ENERGY STAR Announces Updates to Metrics with New Market Data

ENERGY STAR regularly updates their performance metrics based on the most recent market data available. The next update will occur on August 26, 2018 and may result in a change in the 1-100 ENERGY STAR score for buildings across your portfolio. The ENERGY STAR score compares your building’s energy performance to that of similar buildings nationwide. The most recent market data available shows an overall improvement in the energy performance of the U.S. building stock in recent years.

ENERGY STAR is updating the score models across 10 building types (e.g. Offices, Hotels, Warehouses, etc) as well as providing data center estimates and a Source Energy Factor.

When the methodology updates are released the new calculations and values will automatically be applied to all time periods. You will still be able to compare performance over time and analyze differences that are a result of your own activity.

How to prepare:

1) If needed download your pre- and post-update metrics in Excel using Portfolio Manager reports.

it’s important to note that after the metric updates are implemented, EPA will not be able to provide “before and after” score changes for individual buildings or portfolios. To record this information and calculate changes, you’ll need to download the report prior to the August update and again after the update. This may be relevant if you’re participating in third-party certifications or incentives.

2) Apply for ENERGY STAR certification

If you earned 2017 ENERGY STAR certification for your building, you may apply for 2018 certification using a period ending date of April 30, 2018, or earlier. Applications submitted:

  • Before July 26, 2018 and which require no significant follow-up or changes, will be guaranteed to be approved and awarded certification using the existing score models.
  • July 26, 2018 – August 26, 2018 may be evaluated using the updated score models, especially if significant follow-up or changes to the application are required.
  • After August 26, 2018 will be evaluated using the updated score models.

3) Communicate the metric updates to colleagues, clients, stakeholders, etc.

There are a variety of additional materials available from ENERGY STAR here. These include timeline, FAQs, recordings of past webinars, links to register for upcoming webinars, and communications toolkit

What is the ENERGY STAR Score?

The 1 – 100 ENERGY STAR score is a screening tool that helps you assess how your building is performing. It’ll help you identify which buildings in your portfolio to target for improvement or recognition. A score of 50 is the median. So if your building scores below 50, it means it’s performing worse than 50 percent of similar buildings nationwide, while a score above 50 means it’s performing better than 50 percent of its peers. And a score of 75 or higher means it’s a top performer and may be eligible for ENERGY STAR certification.
