NEMA, ASHRAE, and Pacific Northwest National Laboratory (PNNL) have published an AI data center energy performance framework aimed at data center project developers and facility managers working on the design, installation, and ongoing maintenance of critical energy infrastructure. The guidance focuses on electrical and thermal systems, plus integrated designs intended for safe, reliable, resilient operation.
The AI Data Center Energy Performance Framework is organized as a single operating guide that links technical standards, guidance, and deployment considerations for data center environments. It covers energy sourcing, energy use, and water use across data center design, construction, and operations.
For engineers dealing with AI-driven load growth and higher rack densities, this kind of “one place to start” document can be useful—but only if it stays practical at the system level. The most valuable sections will be the ones that connect real design choices (electrical architecture, cooling approach, and control strategies) to measurable outcomes like efficiency, resilience, and commissioning results, rather than repeating generic best-practice language.
The framework calls out best practices and applicable standards across planning and siting, integrated design principles, energy and thermal efficiency, grid-interactive design, resilient design, commissioning and performance validation, operations and maintenance, and retrofit and modernization strategies. It incorporates more than a dozen NEMA technical standards and guidance documents, including resources covering energy storage systems, microgrids, fire and life safety equipment, insulating material, transformers, switchgear, UPS systems, wire and cable, electricity metering, and AC grounding and bonding systems.
“As data centers grow in number, complexity, and scale, it’s imperative that they operate safely, reliably, and as efficiently as possible,” said NEMA President and CEO Debra Phillips. ASHRAE President Bill McQuade said the work is intended to translate “complex technical challenges into clear, actionable strategies” that help operators “make more effective use of energy, while strengthening reliability at both the facility and grid level.” PNNL Director of Buildings and Industrial Programs Bing Liu said the guide is “a dynamic online resource” designed to be updated over time.
NEMA said the framework is intended to reduce uncertainty across project development stages, particularly as the industry prioritizes “speed to power” and evaluates alternative pathways to energization.
