This 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 Standard applies to all variables affecting energy performance that can be monitored and influenced by the organization.

This Standard does not prescribe specific performance criteria with respect to energy.

This Standard has been designed to be used independently, but it can be aligned or integrated with other management systems.

This 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 Standard also provides, in Annex A, informative guidance on its use.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 50001: 2011 Energy management systems-Requirements with guidance for use (lDT)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.

In this Standard, electrical and electronic appliances are in accordance with the Act on Rationalizing Energy Use (hereafter referred to as the Energy Conservation Act), mainly for general household use out of the following specific energy-consuming appliances for which the standard energy consumption efficiency is specified.

The range of CGU includes a prime mover, a generator, a heat recovery facility and pollution abatement equipment for exhaust gas and a cooling facility required for the operation of the prime mover, and a control and monitoring devices required for their operation.

This Standard is not applicable to the stand-alone equipment such as a prime mover, a generator and a heat recovery facility and the reciprocating internal combustion engine driven alternating current generating sets which have been already tested in accordance with other Japanese Industrial Standards and/or International Standards.

— évaluation des effets de structure dans la variation de l'intensité énergétique;

— calcul des indices d'efficacité énergétique;

— analyse de la décomposition de la variation de la consommation d'énergie.

Le présent document permet de fournir une évaluation statistique agrégée d'un pays, d'une région ou d'une ville. Il ne s'applique pas au calcul de l'évolution de la consommation d'énergie ou de l'efficacité énergétique au niveau de consommateurs individuels (par exemple, ménages, organisations, entreprises).

ISO 50047:2016 addresses the following topics in the context of energy savings:

· establishing the purpose of determining energy savings;

· determining boundaries;

· energy accounting, including primary and delivered energy and the use of common energy units;

· selecting an approach for the determination of energy savings;

· establishing an energy baseline;

· normalization of energy consumption;

· determination of energy savings;

· reporting and other matters.

Specific methods for the measurement and verification of energy performance and its improvement are outside the scope of ISO 50047:2016.

ISO 17742:2015 considers all end-use sectors, such as households, industry, tertiary (services, etc.), agriculture, and transport. It does not incorporate calculation of energy efficiency and energy savings in energy supply sectors, such as power plants, refineries, and coal mines.
