ISO 50009:2021(E)

Introduction
ISO 50001 has been developed to enable a single organization to establish the systems and processes
necessary to continually improve energy performance. In some situations, better energy management
results are accomplished when several organizations work together to manage their energy collectively
by forming an energy management group (EnMG). These situations can be driven by changes in
technology and the spread of distributed energy resources.
EnMGs can include organizations which:
— operate in a geographical region, such as a city, district or a single industrial park;
— are in a single sector, such as food processing, rail transportation or universities;
— share a common customer (supply chain members), such as a supermarket chain or car manufacturer;
— are served by a common service supplier, such as a building landlord in a shopping mall;
— share one utility system (steam, electricity, etc.);
— form part of a franchise group, which can have (but does not need to have) a common supplier, such
as a franchised fast food chain (with common supplier), or independent retail stores that operate
under a cooperative banner;
— form part of a wider economic group, with financial links or common ownership;
— are different type of facilities owned by a municipal government (city office, library, hospital, etc.);
— share a common objective or energy target (either voluntarily set or mandated);
— have agreed to improve the same energy performance indicator (EnPI);
— are members of a trade association.
The approach within this document may also be used by a multi-site organization covered by a single or
common management system.
Groups of organizations can derive energy management benefits beyond those realizable by a single
organization through a joint or common approach to energy management by several organizations. In
addition, opportunities can be found by focusing on the energy that flows across the boundaries of each
constituent organization. This type of opportunity cannot be found in a single organization. Generally,
the wider the boundary becomes, the more opportunities there are to improve energy performance and
the amount of improvement.
The establishment of the EnMG can be driven by common energy needs, with the aim of facilitating
synergies or sharing expertise to improve energy performance.
EXAMPLE 1 Large energy investments can be more efficient (one large boiler rather than several small).
EXAMPLE 2 Waste heat or local renewable energy supplies can be shared.
It can be helpful for the implementation of an energy management system (EnMS) for a group of
organizations if at least one constituent organization has experience in energy management.
This document presents guidance on establishing a common EnMS modelled on ISO 50001 but focusing
on the issues that arise when multiple organizations coordinate energy management. The presence
of multiple organizations requires guidance with respect to management aspects of a common EnMS,
such as:
— leadership;
— planning;
vi © ISO 2021 – All rights reserved

ISO 50009:2021(E)

— support for common or joint actions;
— operations or execution of common or joint actions;
— knowledge transfer;
— sharing of best practice;
— performance evaluation;
— ensuring continual improvement.
One additional benefit of a common EnMS is the ability to share expertise, equipment, etc. among
constituent organizations to reduce costs and promote system improvements.
EXAMPLE 3 In an isolated mining or agricultural region it can be costly to bring in expertise (e.g. pumping
experts to reduce energy consumption in irrigated agriculture) or to hire specialized machinery. An EnMG is
often able to share experts’ fees, travel and accommodation costs.

ISO 50009:2021(F)

Introduction
L'ISO 50001 a été élaborée afin de permettre à un seul organisme de mettre en place les systèmes et
les processus nécessaires à l'amélioration continue de sa performance énergétique. Dans certaines
situations, il est possible d'obtenir de meilleurs résultats en matière de management de l'énergie
lorsque plusieurs organismes se regroupent pour gérer collectivement leur énergie en constituant un
groupement de management de l'énergie (GMÉ). Ces situations peuvent être favorisées par l'évolution
des technologies et le développement de la production d'énergie décentralisée (DER).
Les GMÉ peuvent inclure des organismes qui:
— opèrent dans une région géographique, telle qu'une ville, un district ou un parc industriel donné;
— appartiennent à un même secteur, tel que l'industrie alimentaire, le transport ferroviaire ou les
universités;
— fournissent un même client (membres de la chaîne d'approvisionnement), comme une chaîne de
supermarchés ou un constructeur automobile;
— ont pour fournisseur un même prestataire de services, comme un propriétaire d'immeuble dans un
centre commercial;
— partagent un même réseau d'utilités (vapeur, électricité, etc.);
— font partie d'un même groupe de franchise et peuvent avoir (ou non) un fournisseur commun, comme
une chaîne de restauration rapide franchisée (avec un fournisseur commun), ou des magasins de
détail indépendants qui opèrent sous une bannière coopérative;
— font partie d'un groupe économique plus vaste, avec des liens financiers ou un actionnariat commun;
— correspondent à différents types d'installations appartenant à une administration communale
(mairie, bibliothèque municipale, hôpital, etc.);
— partagent un objectif ou une cible énergétique commune (fixée volontairement ou imposée);
— ont convenu d'améliorer le même indicateur de performance énergétique (IPÉ);
— sont membres d'une association professionnelle.
L'approche utilisée dans le présent document peut également être utilisée par un organisme multisite
couvert par un système de management unique ou commun.
Les groupements d'organismes peuvent tirer des avantages en matière de management de l'énergie,
qui vont au-delà de ceux dont peut bénéficier un seul organisme, grâce à une approche commune ou
concertée du management de l'énergie par plusieurs organismes. En outre, des opportunités peuvent
être identifiées en se concentrant sur l'énergie qui traverse le périmètre de chaque organisme membre.
Ce type d'opportunité ne peut pas se trouver dans un seul organisme. En général, plus le périmètre est
large, plus il y a de possibilités d'augmenter la performance énergétique et le degré d'amélioration.
L'établissement du GMÉ peut être motivé par des besoins en énergie communs, dans le but de faciliter
les synergies ou de partager une expertise afin d'améliorer la performance énergétique.
EXEMPLE 1 Les investissements liés à l'énergie de grande ampleur peuvent être plus efficaces (une grande
chaudière plutôt que plusieurs petites).
EXEMPLE 2 La chaleur résiduelle ou les sources d'énergie renouvelable locales peuvent être partagées.
Il peut être utile pour la mise en œuvre d'un système de management de l'énergie (SMÉ) pour un
groupement d'organismes si au moins un organisme membre possède une expérience dans le domaine
du management de l'énergie.

ISO 50009:2021(F)

Le présent document contient des recommandations relatives à l'établissement d'un SMÉ commun, sur
le modèle de l'ISO 50001, mais en mettant l'accent sur les questions qui se posent lorsque plusieurs
organismes se regroupent pour coordonner leur management de l'énergie. La présence de plusieurs
organismes nécessite des recommandations par rapport aux aspects organisationnels d'un SMÉ
commun, tels que:
— le leadership;
— la planification;
— le soutien aux actions communes ou conjointes;
— les opérations ou l'exécution d'actions communes ou conjointes;
— le transfert des connaissances;
— le partage des bonnes pratiques;
— l'évaluation de la performance;
— l'assurance d'une amélioration continue.
Un avantage supplémentaire d'un SMÉ commun est la possibilité de partager l'expertise, l'équipement,
etc., entre les organismes membres, afin de réduire les coûts et de favoriser les améliorations du
système.
EXEMPLE 3 Dans une région minière ou agricole isolée, il peut être coûteux de faire appel à des experts (par
exemple, des experts en pompage pour réduire la consommation d'énergie dans l'irrigation agricole) ou de louer
des machines spécialisées. Un GMÉ est souvent en mesure de partager les honoraires ainsi que les frais de voyage
et d'hébergement des experts.

ISO/FDIS 50009:2020(E)

Introduction
ISO 50001 has been developed to enable a single organization to establish the systems and processes
necessary to continually improve energy performance. In some situations, better energy management
results are accomplished when several organizations work together to manage their energy collectively
by forming an energy management group (EnMG). These situations can be driven by changes in
technology and the spread of distributed energy resources.
EnMGs can include organizations which:
— operate in a geographical region, such as a city, district or a single industrial park;
— are in a single sector, such as food processing, rail transportation or universities;
— share a common customer (supply chain members), such as a supermarket chain or car manufacturer;
— are served by a common service supplier, such as a building landlord in a shopping mall;
— share one utility system (steam, electricity, etc.);
— form part of a franchise group, which may or may not have a common supplier, such as a franchised
fast food chain (with common supplier), or independent retail stores that operate under a
cooperative banner;
— form part of a wider economic group, with financial links or common ownership;
— are different type of facilities owned by a municipal government (city office, library, hospital, etc.);
— share a common objective or energy target (either voluntarily set or mandated);
— have agreed to improve the same energy performance indicator (EnPI);
— are members of a trade association.
The approach within this document may also be used by a multi-site organization covered by a single or
common management system.
Groups of organizations can derive energy management benefits beyond those realizable by a single
organization through a joint or common approach to energy management by several organizations. In
addition, opportunities can be found by focusing on the energy that flows across the boundaries of each
constituent organization. This type of opportunity cannot be found in a single organization. Generally,
the wider the boundary becomes, the more opportunities there are to improve energy performance and
the amount of improvement.
The establishment of the EnMG can be driven by common energy needs, with the aim of facilitating
synergies or sharing expertise to improve energy performance.
EXAMPLE 1 Large energy investments can be more efficient (one large boiler rather than several small).
EXAMPLE 2 Waste heat or local renewable energy supplies can be shared.
It can be helpful for the implementation of an energy management system (EnMS) for a group of
organizations if at least one constituent organization has experience in energy management.
This document presents guidance on establishing a common EnMS modelled on ISO 50001 but focusing
on the issues that arise when multiple organizations coordinate energy management. The presence
of multiple organizations requires guidance with respect to management aspects of a common EnMS,
such as:
— leadership;
— planning;
vi © ISO 2020 – All rights reserved

---------------------- Page: 6 ----------------------
ISO/FDIS 50009:2020(E)

— support for common or joint actions;
— operations or execution of common or joint actions;
— knowledge transfer;
— sharing of best practice;
— performance evaluation;
— ensuring continual improvement.
One additional benefit of a common EnMS is the ability to share expertise, equipment, etc. among
constituent organizations to reduce costs and promote system improvements.
EXAMPLE 3 In an isolated mining or agricultural region it can be costly to bring in expertise (e.g. pumping
experts to reduce energy consumption in irrigated agriculture) or to hire specialized machinery. An EnMG is
often able to share experts’ fees, travel and accommodation costs.
