A concrete Article 11 triage for turning energy-consumption data into the 10 audit route, the 85 TJ energy-management-system route, or a documented out-of-threshold result.
Use it to collect all energy carriers, calculate the previous-three-year average, and keep the enterprise threshold test separate from data-centre and public-body routes.
This workflow is relevant when an enterprise needs to decide whether Article 11 of Directive (EU) 2023/1791 routes it to an energy audit or a certified energy management system. The core calculation is the average annual energy consumption over the previous three years, taking all energy carriers together.
Start with energy data, not company size. Article 11 uses average annual consumption over the previous three years and requires the calculation to take all energy carriers together.
Create one file per enterprise boundary and list each carrier separately before converting totals into a common energy unit. Eurostat describes energy balances as accounting for statistically significant energy products and converting commodity balances into a common energy unit such as .
Do not assume that the tested boundary stops at one legal entity or site. Commission Recommendation (EU) 2024/2002 suggests counting with more than 50% control across the EU, but not ; it also notes that Member States may include partner-enterprise consumption. Treat that as Commission guidance and verify the boundary in the applicable national rule.

Route the result mechanically. The 85 route requires an energy management system certified by an independent body. The 10 TJ route applies to enterprises above 10 TJ that do not implement an energy management system and makes them subject to an energy audit.
The Directive says 'higher than', not 'at least'. An average exactly equal to 10 does not enter the lower Article 11 route, and an average exactly equal to 85 TJ does not enter the higher route, although the lower audit route may still apply at 85 TJ if no energy management system is implemented.
Do not substitute employee count, revenue, sector, or a single electricity meter for the threshold test unless a cited source in the implementation file supports that narrower boundary.
Operational example: annual all-carrier totals of 8 , 12 TJ and 13 TJ produce an average of 11 TJ: (8 + 12 + 13) / 3. That crosses the audit threshold but not the mandatory EMS threshold. If no energy management system is implemented and no qualifying exemption applies, record the audit route and retain the three annual totals and conversion sources.

The audit-route record includes the audit report, a concrete and feasible action plan based on its recommendations, evidence of management submission, and public availability of the action plan and implementation rate subject to trade-secret and confidentiality protections.
For the energy-management-system route, keep evidence that the system monitors actual energy consumption, includes actions to increase energy efficiency, measures progress, and is certified by an independent body under relevant European or international standards.

After the enterprise threshold route is assigned, run two narrow branch checks. These checks do not replace the 10 and 85 TJ calculation; they capture separate EED facts that are based on the directive and Commission material.
Branch only when the facts are present in the evidence file. Do not infer data-centre status from cloud usage alone, and do not infer public-body status from public-sector customers alone.
For an in-scope data centre, separate Article 12 public availability from the directly applicable database duty in Delegated Regulation (EU) 2024/1364. The operator reports the preceding calendar year's information and KPIs by 15 May through a national scheme where one exists or directly to the European database otherwise, and keeps the measurement-point and device record for at least 10 years.
