Practice Description
Power Usage Effectiveness (PUE) is the most widely cited metric in data center efficiency — and one of the most misused. A facility can achieve a low PUE while consuming enormous amounts of water, operating with inadequate resilience, or failing to meet community sustainability obligations. PUE alone is not a sufficient measure of efficiency for AI infrastructure.
EDC Certified™ is LegacyGrid AI's proprietary certification standard. LegacyGrid AI develops, governs, and issues the certification — evaluating efficiency across five dimensions: power, cooling, water, resilience, and sustainability. Each dimension is assessed against documented evidence — not vendor claims or design intent. The result is a LegacyGrid AI-issued certification that owners, investors, and community stakeholders can rely on as an evidence-based record of actual facility performance.
Application
Certification scope must begin with verified operational data. Develop an evidence register, assessment methodology, scoring criteria, and certification documentation. Coordinate with facility operators, utility providers, and community stakeholders while preserving independent certification authority.
Practice Controls
Evaluate efficiency across power, cooling, water, resilience, and sustainability dimensions
Distinguish verified operational performance from design intent or vendor claims
Document evidence sources and assessment methodology for each dimension
Connect certification findings to owner-side decision-making and community reporting
Typical Deliverables
EDC Certified™ assessment report with dimension-by-dimension scoring
Evidence register documenting data sources and verification methodology
Certification documentation for owner, investor, and community use
Remediation roadmap for dimensions that do not meet certification thresholds
Questions We Help Answer
What operational data is available to support an independent efficiency assessment?
What efficiency claims have been made by the facility operator — and what evidence supports them?
What are the water consumption and sustainability performance characteristics of the facility?
What resilience and availability performance does the facility actually deliver?
What community sustainability obligations apply — and how are they being met?
