Energy KPIs
The KPIs come from the plant: nothing to enter. Switch to metered data for real twelve-month totals, or paste monthly data for a regression baseline and verified savings.
Prefilled with the plant model; overwrite with your metered 12-month totals. The readouts show each meter against the model.
Synthetic example: facility = 150 + 1.12·IT + 0.35·CDD MWh with a fixed ±1.5 % pattern, and a 5 % saving in the reporting year. Paste your own meter data.
| Part | KPI | Definition |
|---|---|---|
| 30134-2 | PUE | Total facility energy ÷ IT energy, category 1, 2 or 3 by metering point |
| 30134-3 | REF | Renewable energy ÷ total facility energy |
| 30134-4 | ITEEsv | Server energy-efficiency capability (peak performance ÷ peak power) |
| 30134-5 | ITEUsv | Server utilisation (average ÷ peak capability) |
| 30134-6 | ERF | Energy reused outside the data centre ÷ total facility energy |
| 30134-8 | CUE | CO₂ from data-centre energy ÷ IT energy |
| 30134-9 | WUE | Site water use ÷ IT energy (L/kWh) |
| ISO 50001 clause | PDCA | What a data centre produces |
|---|---|---|
| 4–5 | Plan | Scope and boundary (the metering boundary of M0), energy policy, top-management roles |
| 6 | Plan | Energy review, significant energy uses, EnPIs and energy baselines (ISO 50006), objectives and action plans |
| 7–8 | Do | Competence, operational control of cooling and power, energy considered in design and procurement |
| 9 | Check | Monitoring, measurement and verification of savings (ISO 50015), internal audit, management review |
| 10 | Act | Nonconformity, corrective action, continual improvement of energy performance |
Certification cycle. Initial audit in two stages (documentation, then implementation), a surveillance audit in each of the following two years, and recertification in the third. ISO 50001 additionally requires demonstrated improvement in energy performance, not only a working system.
Related systems. ISO/IEC 27001 (information security, including physical security controls), ISO 22301 (business continuity), ISO 14001 (environmental management). They share the same high-level structure, so one integrated management system can carry all four.
