European foreword
This document (EN 16247-1:2022) has been prepared by the Joint Technical Committee CEN-
CENELEC/JTC 14 “Energy management and energy efficiency in the framework of energy transition”, the
secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2023, and conflicting national standards shall
be withdrawn at the latest by February 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN-CENELEC shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 16247-1:2012.
Significant changes compared to the previous edition are:
a) Terms and definition updated to be compliant with ISO 50001;
b) New Annex A Energy Audit Process Flow Diagram added;
c) New Annex B Examples of energy Audit level added;
d) New Annex C Sampling (Based on ISO 19011:2018 Guidelines for auditing management systems)
added.
This Part covers the general requirements common to all energy audits. There are four further parts of
the EN 16247 series, which provide additional material to Part 1 for four specific sectors.
The other parts of EN 16247 “Energy audits” are:
— Part 2: Buildings;
— Part 3: Processes;
— Part 4: Transport;
— Part 5: Competence of energy auditors.
This document has been prepared under a mandate given to CEN and CENELEC by the European
Commission and the European Free Trade Association.

Introduction
An energy audit is an important step for an organization, whatever its size or type, wanting to improve
its energy performance, reduce energy consumption and bring related environmental and other benefits.
This document defines the attributes of a high-quality energy audit. It states the requirements for energy
audits and corresponding obligations within the energy auditing process. It recognizes that there are
differences in approach to energy auditing in terms of scope, aims and thoroughness, but seeks to
harmonize common aspects of energy auditing in order to bring more clarity and transparency to the
market for energy auditing services. The energy audit process is presented as a simple chronological
sequence; this does not preclude however repeated iterations of certain steps.
This document applies to commercial, industrial, residential and public-sector organizations. This
document does not deal with the energy audit programme/scheme properties (such as programme
administration, training of energy auditors, quality control issues, energy auditors' tools, etc.).
1 Scope
This document specifies the requirements, common methodology and deliverables for energy audits. It
is applicable to all forms of establishments and organizations, all forms of energy and energy uses.
This document covers the general requirements common to all energy audits. Specific energy audit
requirements complete the general requirements in separate parts dedicated to energy audits for
buildings, industrial processes and transport.
2 Normative references
There are no normative references in this document.
