M/479 - Energy audits
Mandate to CEN, CENELEC and ETSI for elaboration of standards regarding energy audits
Mandate M/479 tasks the European Standardization Organizations (CEN, CENELEC, and ETSI) with developing harmonized standards related to energy audits. This mandate aims to support the implementation of energy audit requirements, ensuring consistency and quality across member states. The standards will provide guidelines and technical specifications to facilitate accurate, reliable, and efficient energy assessments in various sectors. The decision on this mandate was addressed through resolution CEN/BT C33/2011 and involves the approval or disapproval process for moving forward with the standardization work.
Purpose
The mandate M/479 aims to authorise the European standardisation bodies CEN, CENELEC, and ETSI to develop standards related to energy audits. The initiative focuses on establishing harmonised methodologies and requirements to facilitate consistent, reliable, and effective energy auditing practices across the European Union.
Standardisation request
The request calls for the creation of standards that define the processes and criteria for conducting energy audits. These standards are intended to guide auditors, energy managers, and relevant stakeholders in performing evaluations of energy consumption and identifying opportunities for energy savings.
Expected deliverables
While specific deliverables are not detailed in the mandate metadata, the expected output includes a suite of European standards that standardise energy audit methodologies. These standards will typically cover aspects such as audit scope, data collection, analysis procedures, reporting requirements, and quality assurance mechanisms.
Context
The mandate was subject to a decision referenced as CEN/BT C33/2011, indicating a formal resolution by CEN’s Board of Directors. The initiative reflects the EU’s broader energy efficiency objectives, as energy audits are instrumental in achieving improved energy management and supporting EU policy goals on sustainability and energy savings. The collaboration between CEN, CENELEC, and ETSI ensures a comprehensive approach encompassing both general energy auditing and the relevant electrotechnical and telecommunications aspects.
The mandate covers the development of standards related to energy audits, focusing on methodologies, processes, and requirements for assessing energy consumption and efficiency in various sectors to support energy savings and compliance with energy-related regulations.
General Information
This document specifies the requirements, methodology and deliverables of an energy audit within a process. These consist of:
a) organizing and conducting an energy audit;
b) analysing the data from the energy audit;
c) reporting and documenting the energy audit findings.
This part of the standard applies to sites or parts of sites where a significant part of the energy use is due to processes. It is used in conjunction with and is supplementary to EN 16247-1, Energy audits - Part 1: General requirements. It provides additional requirements to EN 16247-1 and is applied simultaneously.
A process can include one or more production lines or services, offices, laboratories, research centres, packaging and warehouse sections with specific operational conditions and site transportation. An energy audit can include the whole site or part of a site.
If buildings are included in the scope of the energy audit, the energy auditor can choose to apply EN 16247-2, Energy Audits - Part 2: Buildings. If on-site transport on a site is included in the scope of the energy audit, the energy auditor can choose to apply EN 16247-4, Energy audits - Part 4: Transport.
NOTE The decision to apply Parts 2 and/or 4 is expected to be made during the preliminary contact, see 5.1.

This document is used in conjunction with and is supplementary to EN 16247-1, Energy audits - Part 1: General requirements. It provides additional requirements to EN 16247-1 and is applied simultaneously.
The procedures described here apply to the different modes of transport (road, rail, marine and aviation), as well as the different ranges (local- to long-distance) and what is transported (i.e. goods and people).
This document specifies the requirements, methodology and deliverables specific to energy audits in the transport sector, every situation in which a displacement is made, no matter who the operator is (a public or private company or whether the operator is exclusively dedicated to transport or not), is also addressed in this document.
This document advises on both the optimization of energy within each mode of transport, as well as selecting the best mode of transport in each situation; the conclusions drawn by the energy audit can influence decisions on infrastructure and investment e.g. in teleconferencing or web meetings.
Energy audits of buildings and processes associated with transport can be conducted respectively with the EN 16247-2 Buildings and EN 16247-3 Processes, e.g. pipelines, depots and escalators/travelators. This part of the standard does not include the infrastructure which supplies energy e.g. the electricity generation of energy for railways.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/479 is a European Standardization Mandate titled "Mandate to CEN, CENELEC and ETSI for elaboration of standards regarding energy audits". Mandate to CEN, CENELEC and ETSI for elaboration of standards regarding energy audits There are 16 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
