On March 10, 2023, the European Parliament and Council agreed on the final text of the Energy Efficiency Directive (EED). IDED (formerly known as SDIA) welcomes the agreement as a significant milestone: The new directive includes many elements that IDED has long advocated, which are urgently needed for progress along the SDIA's roadmap towards a sustainable digital infrastructure by 2030.

In the areas of transparency and waste heat utilization, the directive marks an important breakthrough. IDED looks forward to supporting its implementation into national law by member states. Particularly positive: The directive sets an ambitious timeline — the first reporting obligation comes into effect on May 15, 2024.

The Highlights:

- Operators of data centers over 500 kW must publicly disclose their environmental performance at least once a year — including energy consumption, PUE, temperature set points, waste heat utilization, and the use of renewable energy according to CEN/CENELEC EN 50600-4.

- Data centers with a total installed power over 1 MW must recover their waste heat or demonstrate technical or economic impossibility.

- The EU Commission will establish a European data center database where all reported information will be aggregated and published.

- The Commission will use the collected data to present another EED revision by May 15, 2025 — likely with proposals on minimum performance standards and a roadmap to zero-emission data centers.

- The specific metrics and indicators will be defined in the Commission's delegated act. IDED is involved in shaping these metrics — further information is available in our position paper. Even in its current version, the directive is a major step towards transparency.

### Annex VIa

> - the name of the data centre,

> - the name of the owner and operators of the data centre,

> - the date of entry into operation and the municipality where the data centre is based;

> - the floor area of the data centre;

> - the installed power;

> - the annual incoming and outgoing data traffic;

> - and the amount of data stored and processed within the data centre;

> - the performance, during the last full calendar year, of the data centre in accordance with key performance indicators about, inter alia, energy consumption, power utilisation, temperature set points, waste heat utilisation, water usage and use of renewable energy, using as a basis, where applicable, the CEN/CENELEC EN 50600-4 "Information technology - Data centre facilities and infrastructures", until the entry into force of the delegated act pursuant to Article 31 of this Directive.
