    • Applicable to all sizes/sectors; 6-12 months typical; ongoing surveillance audits.

    ENERGY STAR Details

    What It Is

    ENERGY STAR is a U.S. EPA-administered voluntary labeling and benchmarking program for energy efficiency. It establishes category-specific performance specifications for products, homes, commercial buildings, and industrial plants, using standardized test methods and third-party verification to signal superior efficiency.

    Key Components

    • Performance thresholds (e.g., 15% above federal minima for appliances)
    • DOE-referenced test procedures
    • Mandatory third-party certification and 5-20% annual verification testing
    • Brand governance via controlled marks and Portfolio Manager benchmarking (75+ score for certification) Built on four pillars: thresholds, testing, verification, labeling.
