ENERGY STAR Details
What It Is
ENERGY STAR is the U.S. EPA-administered voluntary labeling and benchmarking program for energy efficiency. It sets category-specific performance thresholds for products, homes, commercial buildings, and industrial plants, using standardized DOE test procedures and peer-relative scoring.
Key Components
- Performance thresholds (e.g., 15% above federal minimums, 75+ score for buildings)
- Third-party certification by EPA-recognized labs/CBs
- Post-market verification (5-20% annual testing)
- Portfolio Manager for benchmarking
- Brand governance via controlled marks Certification requires ongoing compliance and annual renewal for buildings.
Why Organizations Use It
Reduces energy costs ($500B saved since 1992), emissions (4B tons avoided), unlocks rebates/procurement. Builds trust (90% recognition), enhances reputation, supports ESG. Voluntary yet de facto standard in many markets.
Implementation Overview
Assess via Portfolio Manager, test/certify products, benchmark buildings, verify annually by PE/RA. Applies to manufacturers, builders, owners across sizes/industries in U.S./Canada. Involves data governance, retrofits, continuous monitoring.
ISO 20000 Details
What It Is
ISO/IEC 20000-1:2018 is the international certifiable standard for establishing, implementing, and improving a service management system (SMS). It focuses on managing the full service lifecycle—planning, design, transition, delivery, and improvement—to ensure consistent service quality. Built on Annex SL high-level structure and PDCA cycle, it emphasizes risk-based thinking and flexibility.
Key Components
- Clauses 4–10 cover context, leadership, planning, support, operation, performance evaluation, and improvement.
- Clause 8 details operational processes: service portfolio, relationships, supply/demand, design/transition, resolution, assurance.
- Core practices include incident/problem management, change control, configuration, availability, continuity, security.
- Certifiable via accredited bodies with Stage 1/2 audits, surveillance, recertification.
Why Organizations Use It
- Drives operational efficiency, risk reduction, customer trust.
- Enables market differentiation, procurement advantages.
- Integrates with ISO 9001, ISO 27001.
- Builds resilience in multi-supplier environments.
Implementation Overview
- Phased: gap analysis, design, deployment, audits (12-18 months typical).
- Applies to all sizes/industries providing services.
- Requires leadership commitment, training, tooling, continual improvement.
