EED Article 12
Annual report by 15 May for the previous calendar year, under Delegated Regulation (EU) 2024/1364. Covers energy use, PUE, WUE, energy reuse and renewable share.
ESG reporting
Energy and ESG reporting for datacenters.
Cyclops reads the energy, water and heat meters in your datacenter, calculates PUE and the other EED indicators, and attributes energy and emissions to tenants and workloads. The output is data you can submit for EED and CSRD reporting and use as evidence for certification.
PUE1.32
- Facility energy
- 1,452 MWh
- IT energy
- 1,100 MWh
- Renewable share (REF)
- 68 %
- Water use (WUE)
- 0.41 L/kWh
PUE = total facility energy ÷ IT equipment energy
What operators must report
Datacenters must now report their energy performance.
Under the EU Energy Efficiency Directive, operators with 500 kW or more of installed IT power report energy and water KPIs to a European database every year. Investors, tenants and certification bodies ask for the same data. Most operators still collect it by hand from meters, building systems and invoices.
CSRD and EU Taxonomy
Scope 1 and 2 emissions, energy mix and alignment with the EU Code of Conduct for Data Centre Energy Efficiency, as expected under Taxonomy activity 8.1.
LEED, BREEAM and others
Green building schemes need measured evidence on energy, water and operations. Verified data also supports access to green finance.
Energy & ESG reporting
One platform for usage, cost and energy data
Cyclops already collects usage data from every resource it bills. It now adds energy and water readings from the facility, so ESG figures come from the same audited source as your invoices.
PUE assessment
Continuous PUE from grid intake, UPS and PDU meters, at hourly, monthly and annual resolution. Partial PUE per hall or cooling zone shows where losses occur.
EED KPI set
PUE, WUE, Energy Reuse Factor (ERF) and Renewable Energy Factor (REF), calculated with the methods referenced in the EED reporting rules and the ISO/IEC 30134 series.
Energy per tenant and per job
IT energy is attributed to projects, tenants, GPU jobs and LLM tokens. Customers receive energy and emissions figures alongside their invoice.
Scope 1 and 2 emissions
Location-based and market-based Scope 2 emissions from metered energy, grid factors and renewable contracts. Scope 1 from on-site generation and refrigerants.
Report-ready exports
Annual EED data set, CSRD energy and climate tables, and evidence packs for LEED, BREEAM and EU Code of Conduct submissions.
Audit trail
Every figure links back to its meter readings and calculation method, so auditors and third-party verifiers can check it.
Where Cyclops measures
Five meters give you the four EED indicators
Cyclops reads the meters most datacenters already have. Total facility energy (M1) and IT energy (M2) give PUE. Water (W), reused heat (H) and renewable supply (R) give WUE, ERF and REF.
Indicators
The four EED indicators, and how Cyclops calculates them
Each indicator follows the method in its ISO/IEC 30134 standard. Cyclops records the meters and readings used, so every value can be traced and checked.
| Indicator | What it measures | Formula | Unit and target | Standard |
|---|---|---|---|---|
| PUEPower Usage Effectiveness | How much energy goes to cooling, power distribution and other overheads | M1 ÷ M2 | Ratio, 1.0 or higher. Lower is better. | ISO/IEC 30134-2 |
| WUEWater Usage Effectiveness | Water used on site per unit of IT energy | W ÷ M2 | L/kWh. Lower is better. | ISO/IEC 30134-9 |
| ERFEnergy Reuse Factor | Share of total energy reused outside the datacenter, for example as district heat | H ÷ M1 | 0 to 1. Higher is better. | ISO/IEC 30134-6 |
| REFRenewable Energy Factor | Share of total energy from renewable sources, on site or contracted | R ÷ M1 | 0 to 1. Higher is better. | ISO/IEC 30134-3 |
M1 = total facility energy · M2 = IT equipment energy · W = site water use · H = reused energy · R = renewable energy. See the diagram above.
PUE assessment
Start with a measured PUE baseline
A PUE assessment is the first step towards EED reporting and certification. We connect to your existing meters, measure PUE over a full operating period and show where energy is lost.
- Connect. Read grid, UPS, PDU, cooling and water meters through BMS, DCIM, Modbus, SNMP or Redfish.
- Measure. Calculate PUE and partial PUE at hourly resolution, with data gaps and meter faults flagged.
- Report. Receive a baseline report with an EED data gap analysis and a list of efficiency measures.
What the assessment covers
- Annual and seasonal PUE, with partial PUE by zone
- WUE, ERF and REF where data is available
- Meter coverage check against EED requirements
- Cooling and power-distribution losses
- Recommended measures ranked by energy saved
Data sources
Works with the meters and systems you already have
Building and DCIM systems
Import readings from building management and DCIM platforms through their APIs or scheduled exports.
Meters and devices
Read energy, water and heat meters, UPS units and PDUs directly over Modbus, SNMP and Redfish.
Contracts and certificates
Add utility invoices, power purchase agreements and guarantees of origin for renewable share and Scope 2.
Prepare for your next EED report
Start with a PUE assessment of your site. We will show which data you already have, what is missing for EED reporting, and where energy can be saved.
