Updates to ENERGY STAR® metrics with new market data
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.
