What your 1 – 100 ENERGY STAR score means

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.

The ENERGY STAR score provides a comprehensive snapshot of your building’s energy performance. It assesses the building’s physical assets, operations, and occupant behavior in a quick and easy-to-understand number.

What the 1-100 ENERGY STAR score does (and doesn’t) tell you

EPA, in conjunction with stakeholders, developed the 1 – 100 ENERGY STAR score as a screening tool; it does not by itself explain why a building performs a certain way, or how to change the building’s performance. It does, however, help you assess how your building is performing and identify which buildings offer the best opportunities for improvement and recognition.

The Score Does

The Score Does Not

  • Evaluate actual billed energy data
  • Normalize for business activity (hours, workers, climate)
  • Compare buildings to the national population
  • Indicate the level of energy performance
  • Sum the energy use of each piece of equipment
  • Credit specific technologies
  • Compare buildings with others in Portfolio Manager
  • Explain why a building performs well or poorly

Poor performers save the most

In an analysis of more than 30,000 buildings that benchmarked consistently in Portfolio Manager over a 3-year period, EPA found that buildings that start with lower ENERGY STAR scores and higher energy use achieve the greatest savings.

In fact, buildings starting with ENERGY STAR scores below 50 saved twice as much energy as those starting with higher ENERGY STAR scores.
