1 Scope This International Standard specifies requirements for establishing, implementing, maintaining and improving
an energy management system, whose purpose is to enable an organization to follow a systematic approach
in achieving continual improvement of energy performance, including energy efficiency, energy use and
consumption. This International Standard specifies requirements applicable to energy use and consumption, including
measurement, documentation and reporting, design and procurement practices for equipment, systems,
processes and personnel that contribute to energy performance. This International Standard applies to all variables affecting energy performance that can be monitored and
influenced by the organization. This International Standard does not prescribe specific performance criteria
with respect to energy. This International Standard has been designed to be used independently, but it can be aligned or integrated
with other management systems. This International Standard is applicable to any organization wishing to ensure that it conforms to its stated
energy policy and wishing to demonstrate this to others, such conformity being confirmed either by means of
self-evaluation and self-declaration of conformity, or by certification of the energy management system by an
external organization. This International Standard also provides, in Annex A, informative guidance on its use.
