FOREWORD
1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in
the development of International Standards. Their preparation is entrusted to technical committees; any ISO and
IEC member body interested in the subject dealt with may participate in this preparatory work. International
governmental and non-governmental organizations liaising with ISO and IEC also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
3) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC and ISO member bodies.
4) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the
technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held responsible for
the way in which they are used or for any misinterpretation by any end user.
5) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and
ISO/IEC publications transparently to the maximum extent possible in their national and regional publications.
Any divergence between any ISO/IEC publication and the corresponding national or regional publication
should be clearly indicated in the latter.
6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for
any equipment declared to be in conformity with an ISO/IEC publication.
7) All users should ensure that they have the latest edition of this publication.
8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC or ISO member bodies for any personal injury, property
damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees)
and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC publication or any other IEC,
ISO or ISO/IEC publications.
9) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
10) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
ISO/IEC 15067 currently consists of three parts. All parts were previously published as
Technical Reports. ISO/IEC 15067-3, energy management, is being upgraded to a standard at
the request of the IEC Standards Management Board study group on energy efficiency (SG1
SMB-SG 1/0027/INF, July 2008, Recommendation 16). Energy management is becoming an
essential part of the worldwide development of smart grids for electricity.
Part 2: Lighting model for HES
Part 3: Model of a demand-response energy management system for HES (this document)
Part 4: Model of a security system for HES
SC 25/WG 1, the Home Electronic System (HES) working group, has developed these models
to foster interoperability among products from competing or complementary manufacturers.
Product interoperability is essential when using home control standards, such as HES. This
International Standard defines a standard framework for a generic energy management
system and describes the communications services needed. A high-level model for an energy
management system using HES is presented.
Homebuilders, suppliers of building materials and consumer product manufacturers all affect
energy consumption in buildings. Products and services intended for energy management can
be provided by
• programs developed for consumers by electricity suppliers, typically a public utility,
• products purchased by consumers independent of electricity supplier programs.
Various methods for managing the electricity supply network, called the “electricity grid,” have
been developed. The goal of these methods is to match the customer demand for power with
the available supply. The need for such methods results from
• electric supply limitations,
• public resistance to building large generating plants,
• public concern for environmental pollution, including greenhouse gases,
• public opposition to siting of new transmission lines,
• an anticipated demand for and availability of electricity for charging electric vehicles,
• public interest and support for renewable sources of energy,
• the introduction of distributed energy resources (DER) with local generators such as wind
turbines and solar photo-voltaic (PV) panels,
• the variable and unpredictable nature of wind and solar distributed generation with output
that may fluctuate with time and weather,
• the development of batteries and other advanced premises storage technologies plus
power conditioning and management equipment,
• the introduction of alternative electricity pricing methods or tariffs that encourage
efficiency.
The model presented in this standard focuses primarily on methods known as “demand
response” (DR). Because demand response systems extend beyond the meter into customer
premises, those impacted by demand response technology choices include utilities, third-
party suppliers of demand response services, home network developers, appliance and DER
manufacturers and consumers. An example of a third-party provider of demand response
services is an aggregator serving a large building or neighbourhood.
Three types of DR are specified in this standard: direct control, local control and distributed
control. The choice of DR method will vary by utility to achieve the load shape that aligns with
supply limitations, transmission and distribution capabilities, regulatory constraints and
---------------------- Page: 8 ----------------------

business considerations. However, distributed control offers consumers the most flexibility in
adapting appliance operation to constraints imposed by the utility. The various standards
developed by JTC 1/SC 25 for the Home Electronic System are important for effective
distributed control, as specified.
DR is one element in the concept of the “smart grid”. The smart grid for electricity integrates
subsystems for generation, transmission, distribution and customer services to improve the
reliability and efficiency of electricity systems. The smart grid also extends these subsystems
to accommodate distributed energy resources and demand response. A goal of the smart grid
is to enable all these subsystems to interoperate using information technology. Therefore, this
standard is an important contribution to the smart grid.
As the market develops for energy management products, consumer electronics companies,
appliance manufacturers and other residential suppliers may offer products that combine load
management using demand response with energy conservation. Energy conservation may
offer methods for consumers to reduce energy consumption overall, in addition to reducing
consumption at times of peak demand. These methods include products and systems for
electricity generation, storage and management. Such products and systems are located on
premises and can communicate with other on-premises products and systems in order to
interoperate as a larger system. Examples are included in Annex A. Standards for these
products are anticipated to expand this energy management model in future updates.

HOME ELECTRONIC SYSTEM (HES) APPLICATION MODEL –
Part 3: Model of a demand-response energy
management system for HES
1 Scope
This part of ISO/IEC 15067 focuses on products and services that can manage energy
consumption and generation of devices dynamically in response to electricity supply and
prices that may vary over time. The model specified here for energy management is intended
to be generic and representative of a wide range of situations. This part of ISO/IEC 15067
applies to the customer services portion of the electricity smart grid.
This standard specifies an energy management model for programs that manage the
consumer demand for electricity using a method known as “demand response”. Three types of
demand response are specified in this standard: direct control (5.3.1), local control (5.3.2.2)
and distributed control (5.3.2.3).
NOTE Customers and customer equipment may use these methods to control the energy consumption and
generation of devices such as appliances and distributed energy resources (for example, photo-voltaic [PV], wind,
fuel cell [FC], combined heat and power [CHP], electric vehicle [EV], and stationary battery [SB]).). The taxonomy
and lexicon of an energy management model that supports these demand response methods are presented in 7.3
and 7.4.
