What is ISO/IEC 30134-2:2026 on power usage effectiveness in data centres?
ISO/IEC 30134-2:2026 defines Power Usage Effectiveness (PUE), the globally recognized key performance indicator (KPI) for quantifying how efficiently a data centre uses energy. As digital infrastructure continues to grow and power consumption becomes a growing concern, PUE provides organizations with a standardized way to measure the energy performance of their data centres and identify opportunities for improvement.
This updated edition includes new guidance for mixed-use buildings, updated measurement requirements, and greater clarity around unaccounted energy and on-site generation.
Why is measuring power usage effectiveness (PUE) important?
With demand for cloud computing, streaming, and AI skyrocketing, data centres have become critical, and energy-intensive, infrastructure. Governments and businesses alike are under increasing pressure to optimize energy use, reduce emissions, and meet sustainability goals. PUE helps organizations do just that by tracking how much energy is used by computing equipment compared to total facility energy consumption.
Used correctly, PUE enables smarter design, investment, and operations decisions, whether you're operating a hyperscale data centre or managing a small enterprise facility.
Benefits
- Track and benchmark data centre energy efficiency using a globally accepted metric
- Improve transparency with clearly defined measurement categories and reporting rules
- Identify energy waste in cooling, power distribution, and other supporting infrastructure
- Support sustainability and emissions reduction goals through better energy insight
- Use the mPUE variant to assess energy performance in mixed-use buildings
FAQ
This standard outlines how to measure, calculate, and report PUE accurately and consistently. It introduces multiple PUE measurement categories, guidance for on-site energy generation, and rules for dealing with unmeasured energy, making it easier to compare facilities over time or across organizations.
Yes. By identifying inefficiencies in your infrastructure, such as overcooling or poor energy distribution, PUE provides actionable insight to reduce energy use, cut costs, and support environmental targets.
