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

is applicable to all forms of establishments and organizations, all forms of energy and energy uses.
