Showing 18 of 38 items.* ### [What evidence should support the audit report?](/artifacts/eu/energy-efficiency-directive/faq/audit-report-contents.md#what-evidence-should-support-the-audit-report) *Module: [EED energy audit report contents: what should be included?](/artifacts/eu/energy-efficiency-directive/faq/audit-report-contents.md)* The evidence file should let the enterprise, auditor, competent authority, or later reviewer reproduce the main conclusions without relying on memory. Annex VI expressly requires audit data to be storable for historical analysis and performance tracking. - Measured data extracts, meter registers, bills, submetering exports, production or occupancy data used for normalization, and electricity load profiles where relevant. - Site list, process list, transport boundary, sampling rationale, and explanation of why the audited sample is representative. - Calculation sheets for each proposed measure, with baseline, expected savings, cost assumptions, life-cycle cost inputs, residual value assumptions, discount-rate assumptions, and sensitivity notes where used. - Recommendation register showing energy efficiency measures, renewable energy opportunities, technical feasibility, economic feasibility, responsible owner, and action-plan status. - Quality-control evidence such as auditor qualifications or independence checks required by the Member State scheme, review comments, and final management submission record. - A retained historical archive so future audits can compare performance, validate implementation, and update measures rather than starting from scratch. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Annex VI requires detailed and validated calculations and storable audit data for historical analysis and performance tracking. - [Commission study on minimum criteria for energy audits and energy management systems](https://energy.ec.europa.eu/publications/study-guidance-member-states-minimum-criteria-energy-audits-and-energy-management-systems_en?ref=sorena.io) - Commission publication frames the minimum-criteria study as guidance for authorities implementing Article 8 and Annex VI requirements. ### [How should the report connect to recommendations and the Article 11 action plan?](/artifacts/eu/energy-efficiency-directive/faq/audit-report-contents.md#how-should-the-report-connect-to-recommendations-and-the-article-11-action-plan) *Module: [EED energy audit report contents: what should be included?](/artifacts/eu/energy-efficiency-directive/faq/audit-report-contents.md)* For enterprises subject to Article 11(2), the audit report should be written so the recommendations can be converted into a concrete and feasible action plan. Article 11 says the action plan is based on the audit recommendations, identifies measures to implement each recommendation where technically or economically feasible, and is submitted to enterprise management. - Recommendation text should identify the affected system, expected energy saving, implementation dependency, cost basis, and calculation reference. - Feasibility notes should distinguish technical blockers from economic blockers instead of merging both into a vague priority score. - The management submission package should include the audit report, recommendation register, action plan, exception rationale for non-implemented recommendations, and implementation-rate method. - Confidential business information should be separated from publishable action-plan and implementation-rate content so Article 11 transparency can be handled without exposing protected details. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 11 links audit recommendations to a concrete action plan, management submission, and publication of action-plan and implementation-rate information. - [EN 16247-1:2022 energy audits standard catalog entry](https://standards.iteh.ai/catalog/standards/cen/3fbb3fd5-0106-42d0-8b9f-cb546db8465a/en-16247-1-2022?ref=sorena.io) - Standards catalog material supports treating energy audit reporting as part of a structured audit methodology and deliverables set. ### [Does the EU Energy Efficiency Directive set a single penalties table?](/artifacts/eu/energy-efficiency-directive/faq/penalties.md#does-the-eu-energy-efficiency-directive-set-a-single-penalties-table) *Module: [EED penalties: what does Directive (EU) 2023/1791 require?](/artifacts/eu/energy-efficiency-directive/faq/penalties.md)* No. Article 32 creates a Member State obligation, not a single EU penalty schedule for companies to copy into a checklist. Member States must lay down penalty rules for infringements of national provisions adopted under the EED, take the measures needed to implement them, and ensure the penalties are effective, proportionate, and dissuasive. - Use Article 32 for the Directive-level rule: penalties are created and implemented through Member State national provisions. - Do not publish or rely on country-specific fine amounts unless the relevant national law source has been checked. - Tie any enforcement assessment to the exact national EED obligation at issue: threshold assessment, certified energy management system, energy audit, action plan, annual-report publication, authority filing, or data-centre reporting where relevant. Sources for this answer: - [Directive (EU) 2023/1791 Article 32 penalties provision](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Primary legal source showing that Member States set and implement EED penalty rules and that penalties must be effective, proportionate, and dissuasive. - [European Commission revised EED implementation guidance announcement](https://energy.ec.europa.eu/news/commission-publishes-final-guidance-documents-implementing-revised-energy-efficiency-directive-2024-09-23_en?ref=sorena.io) - Supports the national-transposition framing because the Commission describes guidance for Member States transposing the revised EED into national law. ### [What evidence reduces EED enforcement risk for Article 11?](/artifacts/eu/energy-efficiency-directive/faq/penalties.md#what-evidence-reduces-eed-enforcement-risk-for-article-11) *Module: [EED penalties: what does Directive (EU) 2023/1791 require?](/artifacts/eu/energy-efficiency-directive/faq/penalties.md)* For Article 11, the first evidence file is the threshold and route analysis. The Directive uses average annual energy consumption over the previous three years, taking all energy carriers together, to identify enterprises above the 85 TJ energy-management-system route and enterprises above the 10 TJ audit route where no energy management system is implemented. - Three-year energy-consumption calculation by energy carrier, including source data and the enterprise boundary used for the national filing. - Article 11 route conclusion: certified energy management system route, audit route, environmental management system route, energy performance contract route, or out-of-scope rationale. - Certification evidence for an energy management system: standard, independent certification body, certificate scope, covered sites, covered activities, and expiry or surveillance status. - Audit-route evidence: qualified or accredited expert evidence, independence or authority-supervision evidence, audit report, and timing record for first and subsequent audits. - Action-plan evidence: recommendations, technical or economic feasibility decisions, implementation measures, management submission, implementation-rate method, and confidentiality basis for any public reporting limit. Sources for this answer: - [Directive (EU) 2023/1791 Article 11 on energy management systems and energy audits](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Supports the 85 TJ and 10 TJ Article 11 routes, independent certification, audit route, action plan, management submission, and implementation-rate publication requirements. - [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Commission overview supports the practical focus on audit obligations, energy management systems, and competent professionals under the revised EED. ### [What counts as a public body under the EU Energy Efficiency Directive?](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md#what-counts-as-a-public-body-under-the-eu-energy-efficiency-directive) *Module: [EED Public Bodies FAQ: 1.9% Reduction and 3% Renovation Duties](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md)* Directive (EU) 2023/1791 defines public bodies as national, regional or local authorities and entities directly financed and administered by those authorities, provided the entity does not have an industrial or commercial character. - Classify the entity: national, regional, local authority, or directly financed and administered non-commercial entity. - Separate public-body consumption from commercial or industrial activity where the national transposition draws that line. - Keep the scope file tied to national implementation, because the directive sets EU minimum requirements and Member States may introduce stricter measures. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Defines public bodies and states that the directive's requirements are minimum requirements that Member States may make stricter. - [EUR-Lex record for Directive (EU) 2023/1791](https://eur-lex.europa.eu/legal-content/en/ALL/?uri=CELEX%3A32023L1791&ref=sorena.io) - Supports the public-sector context, including the recital that public bodies should cover final energy consumption across public services and installations. ### [What is the 1.9% public-sector energy consumption reduction duty?](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md#what-is-the-19-public-sector-energy-consumption-reduction-duty) *Module: [EED Public Bodies FAQ: 1.9% Reduction and 3% Renovation Duties](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md)* Article 5 requires Member States to ensure that the total final energy consumption of all public bodies combined is reduced by at least 1.9% each year compared with 2021. - Baseline: final energy consumption of all public bodies for 2021, subject to the directive's public transport and armed-forces caveat. - Reduction: at least 1.9% each year compared with 2021 for all public bodies combined. - Transitional status: the Article 5 target is indicative until 11 October 2027, and Member States may use estimated consumption data during that period before aligning the baseline with actual consumption. - Reporting: national energy and climate plan updates must include the reduction to be achieved by all public bodies, disaggregated by sector; progress reports must report the achieved annual final energy consumption reduction. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 5 is the direct source for the public-body 1.9% final energy consumption reduction, 2021 baseline, transitional period, and reporting duties. - [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Commission overview identifies the revised EED and links the public-sector Articles 5, 6 and 7 guidance. ### [What is the 3% renovation duty for public bodies' buildings?](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md#what-is-the-3-renovation-duty-for-public-bodies-buildings) *Module: [EED Public Bodies FAQ: 1.9% Reduction and 3% Renovation Duties](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md)* Article 6 requires each Member State to ensure that at least 3% of the total floor area of heated and/or cooled buildings owned by public bodies is renovated each year so those buildings are transformed into at least nearly zero-energy buildings or zero-emission buildings. - Covered building stock: heated and/or cooled buildings owned by public bodies, over 250 m2 total useful floor area, and not nearly zero-energy buildings on 1 January 2024. - Output standard: renovation to at least nearly zero-energy building or zero-emission building level. - Selection discretion: Member States may choose which buildings to include while considering cost-effectiveness and technical feasibility. - Occupied buildings: keep lease, trigger-point, and owner-negotiation records when the public body occupies a building it does not own. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 6 is the direct source for the 3% annual renovation rate, the over-250 m2 calculation base, the 1 January 2024 building-stock reference, and occupied-building negotiation duty. - [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Commission overview summarizes the EED public-building renovation policy and points to public-sector implementation guidance. ### [Which exclusions and caveats matter for public bodies?](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md#which-exclusions-and-caveats-matter-for-public-bodies) *Module: [EED Public Bodies FAQ: 1.9% Reduction and 3% Renovation Duties](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md)* The public-sector duties have important caveats. For Article 5, Member States may exclude public transport or the armed forces from the 2021 baseline and obligation, although reductions from those areas are still indicative and may still count. - Record whether public transport or armed-forces consumption is included, excluded, or counted indicatively. - Record the population band for local administrative units affected by the temporary Article 5 exclusions. - For building exclusions, retain the protected-status, defence-use, worship-use, social-housing, cost-neutrality, or feasibility basis. - Do not count a building renovation toward the Article 6 rate if the Member State has decided that transforming that building is technically, economically, or functionally infeasible. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Supports Article 5 public transport, armed-forces, population, and transitional caveats, plus Article 6 building categories and feasibility caveats. - [EUR-Lex record for Directive (EU) 2023/1791](https://eur-lex.europa.eu/legal-content/en/ALL/?uri=CELEX%3A32023L1791&ref=sorena.io) - Source metadata captures the temporary Article 5 local-administrative-unit exclusions for 50,000 and 5,000 inhabitant thresholds. ### [What records should public bodies keep for EED reporting?](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md#what-records-should-public-bodies-keep-for-eed-reporting) *Module: [EED Public Bodies FAQ: 1.9% Reduction and 3% Renovation Duties](/artifacts/eu/energy-efficiency-directive/faq/public-bodies.md)* The most useful evidence file connects the entity scope, the 2021 consumption baseline, sector allocation, annual reduction measures, building inventory, renovation decisions, and reported outcomes. This is especially important because Article 5 asks Member States to report public-body consumption reductions through national energy and climate progress reporting. - Public-body register: entity name, authority level, financing and administration basis, non-commercial character, and national-transposition scope decision. - Consumption records: 2021 baseline, final energy consumption data, estimates used during the transitional period, actual-data reconciliation, sector disaggregation, and climate-variation adjustment if used. - Reduction measures: responsible owner, measure description, affected service or installation, expected and achieved final energy consumption reduction, and reporting period. - Building inventory: owner or occupier status, floor area, heating/cooling status, annual energy consumption where available, energy performance certificate, renovation status, and exclusion or feasibility notes. - Procurement and lease records: energy-efficiency-first assessment, owner negotiations for occupied buildings, and any energy performance contracting assessment for large public-building renovations. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 5 supports sector-disaggregated planning and annual reporting; Article 6 supports the public-building inventory fields and update cadence. - [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Commission overview confirms the revised EED framework and its public-sector guidance context for Articles 5, 6 and 7. ### [How often must EU EED Article 11 energy audits be repeated?](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md#how-often-must-eu-eed-article-11-energy-audits-be-repeated) *Module: [EU EED audit frequency: Article 11 cadence and EMS route](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md)* For enterprises in the audit route, Article 11 requires a first energy audit by 11 October 2026 and subsequent audits at least every four years. The trigger is not company size alone: it is average annual energy consumption higher than 10 TJ over the previous three years, taking all energy carriers together, where the enterprise does not implement an energy management system. - Audit route: average annual consumption higher than 10 TJ over the previous three years, all energy carriers together, and no qualifying energy management system. - First audit date in the Directive: by 11 October 2026 for enterprises in the Article 11(2) audit route. - Repeat cadence: at least every four years after the previous qualifying energy audit. - National caveat: Member States transpose and enforce Article 11, so local rules can define the competent authority process and practical filing expectations. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 11 sets the 10 TJ audit threshold, first audit deadline, and at-least-four-year cadence. - [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Commission overview confirms that the recast EED expands audit obligations by energy-consumption threshold and requires Member State transposition. ### [When does an energy management system replace the audit route?](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md#when-does-an-energy-management-system-replace-the-audit-route) *Module: [EU EED audit frequency: Article 11 cadence and EMS route](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md)* Article 11 uses a higher threshold for the energy management system route. Enterprises with average annual consumption higher than 85 TJ over the previous three years, taking all energy carriers together, must implement an energy management system certified by an independent body according to relevant European or international standards. - Above 85 TJ average annual consumption: certified energy management system route. - Above 10 TJ average annual consumption without an energy management system: energy audit route. - The thresholds use the previous three years and aggregate all energy carriers. - Keep certification evidence for the management system because the audit alternative depends on the system actually qualifying under Article 11. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 11 identifies the 85 TJ energy management system obligation and the 11 October 2027 latest implementation date. - [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Commission overview explains that energy management systems become mandatory for large industrial energy consumers. ### [What should trigger an audit-frequency review?](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md#what-should-trigger-an-audit-frequency-review) *Module: [EU EED audit frequency: Article 11 cadence and EMS route](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md)* Review audit frequency whenever annual energy-consumption data could move the enterprise above or below the Article 11 thresholds. Article 11 also requires Member States to ensure that, where an enterprise exceeds the relevant annual consumption threshold in a given year, that information is made available to the national authorities responsible for implementation. - Annual energy use exceeds 10 TJ or 85 TJ in a given year. - A merger, divestment, site opening, shutdown, production change, or fuel-switch changes the energy-carrier boundary. - A management system certificate expires, changes scope, or no longer covers the relevant enterprise boundary. - A Member State publishes new transposition, platform, authority-notification, or auditor-qualification requirements. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 11 requires threshold information to be available to national authorities and defines the annual-consumption thresholds used for implementation. ### [What evidence should be kept for Article 11 audit cadence?](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md#what-evidence-should-be-kept-for-article-11-audit-cadence) *Module: [EU EED audit frequency: Article 11 cadence and EMS route](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md)* The evidence file should prove both threshold status and audit quality. For threshold status, keep the rolling three-year consumption calculation, the included energy carriers, annual data, and any national authority submission or platform confirmation. For audit cadence, keep the audit date, scope, auditor qualification or supervisory route, report, management submission, and the next due date. - Rolling three-year average energy-consumption workbook, with all energy carriers and enterprise boundaries stated. - Energy management system certificate and scope, where the enterprise relies on the EMS route. - Energy audit report, audit date, covered sites or operations, auditor qualification/accreditation or independent-authority supervision evidence. - Action plan showing recommended measures, technical or economic feasibility decisions, management submission, and implementation-rate publication record. - Historical audit data and calculation files sufficient to track performance and support the next four-year cadence review. Sources for this answer: - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 11 and Annex VI support the evidence list: audit quality criteria, action plans, management submission, publication of implementation rate, and historical data retention. ### [What caveats matter before relying on the EU-level dates?](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md#what-caveats-matter-before-relying-on-the-eu-level-dates) *Module: [EU EED audit frequency: Article 11 cadence and EMS route](/artifacts/eu/energy-efficiency-directive/faq/audit-frequency.md)* The EU-level dates are useful planning anchors, but Article 11 is implemented through Member State law. The Commission overview states that EU countries had a 11 October 2025 transposition deadline for the revised directive and links guidance for transposing Article 11. A company operating in several Member States should therefore treat the Directive as the baseline and confirm each national implementation path. - Use 11 October 2026 as the Directive-level first audit date for the Article 11(2) audit route. - Use 11 October 2027 as the Directive-level latest EMS-in-place date for the Article 11(1) route. - Confirm national transposition before deciding filings, penalties, authority notifications, and auditor qualification details. - Avoid assuming old non-SME-only audit rules still control, because the recast Directive uses energy-consumption thresholds. Sources for this answer: - [European Commission Energy Efficiency Directive overview](https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficiency-targets-directive-and-rules/energy-efficiency-directive_en?ref=sorena.io) - Commission overview states the revised EED transposition deadline and lists Article 11 guidance for Member States. - [Directive (EU) 2023/1791 on energy efficiency](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023L1791&ref=sorena.io) - Article 39 addresses entry into force and application, while Article 11 provides the first audit and EMS dates used as EU-level planning anchors. ### [Can EED records be reused for CSRD or ESRS E1 evidence?](/artifacts/eu/energy-efficiency-directive/faq/csrd-and-esrs-e1-overlap.md#can-eed-records-be-reused-for-csrd-or-esrs-e1-evidence) *Module: [How can EED records support CSRD and ESRS E1 evidence?](/artifacts/eu/energy-efficiency-directive/faq/csrd-and-esrs-e1-overlap.md)* Yes, but only as evidence inputs. The Energy Efficiency Directive creates energy-related records that may help a reporting team substantiate energy consumption, energy-efficiency actions, and data-centre performance. Those records do not themselves determine whether an undertaking is in CSRD scope or what ESRS E1 requires in a sustainability statement. - Use EED audit files to evidence measured energy use, load profiles, audited sites, recommended measures, and management follow-up. - Use EED management-system records to evidence energy objectives, monitoring of actual consumption, actions taken, and measurement of progress. - Use EED data-centre records to evidence published performance information, key performance indicators, water footprint data, waste-heat use, and renewable-energy use where the data centre reporting obligation applies. - Do not cite an EED source as proof of CSRD scope, ESRS E1 materiality conclusions, ESRS datapoint wording, assurance level, or sustainability-report timing.

A reporting team can test whether an EED record is reusable by asking whether the record is measured or traceable, whether the organizational boundary is clear, whether the period is clear, and whether the owner can explain how the data was produced. - Energy-consumption evidence: annual energy consumption, energy carriers included, metering source, site or enterprise boundary, and comparison period. - Audit evidence: audited facilities or operations, measured consumption data, load profiles, identified efficiency measures, feasibility assumptions, and recommendation status. - Management evidence: energy objective, responsible owner, approved action plan, implementation status, and progress measurement. - Data-centre evidence: installed IT power boundary, published Article 12 information, energy consumption, power utilisation, temperature set points, waste heat utilisation, water usage, and renewable-energy use. - Reporting bridge: a separate mapping note that links each EED record to the CSRD or ESRS E1 source that actually requires or explains the disclosure.

Those are CSRD and ESRS questions and need separate CSRD, ESRS, and reporting-standard sources. - Blocked by EED-only grounding: whether a specific company is required to report under CSRD. - Blocked by EED-only grounding: the exact ESRS E1 datapoints, metrics, and disclosure wording. - Blocked by EED-only grounding: CSRD assurance requirements and auditor expectations. - Blocked by EED-only grounding: CSRD or ESRS reporting dates, transition relief, and phase-ins. - Supported by EED grounding: the existence and content of EED energy audit, management-system, action-plan, and data-centre performance records.

It should show which EED obligation or voluntary EED-aligned practice created the record, who owns it, which facilities or entities it covers, which period it covers, and which separate CSRD or ESRS source uses the record as evidence. - Record ID: name the audit, energy management system, action plan, or data-centre reporting file. - EED basis: cite Article 11, Article 12, Annex VI, Annex VII, or the Commission data-centre page as applicable. - Boundary: state the enterprise, facility, data centre, energy carriers, reporting period, and excluded confidential information. - Data quality: identify source systems, meters, operational datasets, review owner, and any estimates or corrections. - Reporting link: cite the separate CSRD or ESRS source and the exact sustainability-reporting claim the EED evidence supports. - Limit: state that the EED record is supporting evidence, not the legal basis for the CSRD or ESRS disclosure.
