ENERGY STAR Details
What It Is
ENERGY STAR is the U.S. EPA's voluntary labeling and benchmarking program for superior energy efficiency. It sets category-specific performance thresholds above federal minimums using standardized DOE test procedures, covering products, homes, commercial buildings, and industrial plants.
Key Components
- Performance thresholds (e.g., 15% above minimums for appliances)
- Third-party certification via EPA-recognized labs/CBs
- Ongoing verification testing (5-20% models annually)
- Portfolio Manager for 1-100 building scores (75+ for certification)
- Strict brand governance and mark usage rules Certification requires annual third-party verification for buildings/plants.
Why Organizations Use It
Drives $500B+ savings, 5T kWh reduced, 4B tons GHG avoided. Unlocks rebates, procurement advantages, ESG credibility. Mitigates risks from misuse/delisting; enhances reputation via trusted label (90% recognition).
Implementation Overview
Assess via Portfolio Manager; test/design for compliance; certify through CBs; maintain via verification/reporting. Suits all sizes/industries; U.S./Canada focus. Involves labs, audits, data submission; continuous for sustained certification.
