A statement from the proposer as to how the proposed work may relate to or impact on
existing work, especially existing ISO and IEC deliverables. (The proposer should explain
how the work differs from apparently similar work, or explain how duplication and conflict
will be minimized. If seemingly similar or related work is already in the scope of othercommittees of the organization or in other organizations, the proposed scope shalldistinguish between the proposed work and the other work. The proposer shall indicate
whether his or her proposal could be dealt with by widening the scope of an existingcommittee or by establishing a new committee.)
The proposed new field of technical activities on HSN will complement and strengthen existing
ISO activities and successful industry initiatives to clean energy transition, infrastructure andetc. in line with ISO STRATEGY 2030 and UN SDGs. The proposed TC will provide anopportunity to widely apply the relevant ISO standards in the form of integrated solution ofHSN.
Based on the analysis, the HSN standards program falls outside the scope of relevant, existingTCs, namely ISO/TC 11 Boilers and pressure vessels – STANDBY, ISO/TC 86 Refrigeration
and air-conditioning, ISO/TC 163 Thermal performance and energy use in the built
environment, ISO/TC 205 Building environment design, ISO/TC 267 Facility management,
ISO/TC 268 Sustainable cities and communities, ISO/TC 301 Energy management and energy
savings, and IEC SyC Smart Cities, IEC SyC Smart Energy and any other technicalcommittees.
The successful delivery of a holistic HSN standardization program therefore requires a newcommittee, and dedicated committee support, which brings together all stakeholders. By
establishing liaisons with relevant technical committees and its related SCs, any potential
overlap or duplication could be managed and minimized. Engagement will be put in place toensure effective collaboration among ISO and IEC technical committees and other interested
members in moving related activities forward.
Standards on sustainability of civil engineering works, developed by TC 59/SC 17, will bereferred to as relevant.
A listing of relevant countries where the subject of the proposal is important to theirnational commercial interests.
The proposed standards program has good geographic representative from Asia, Europe withdiverse economic and climatic situations. Denmark, Sweden, Finland, Norway, Germany,
Poland and other ISO members, such as Russia and South Korea, have a lot of practices on
this field.
A holistic standards program for HSN at the ISO level will help to support the global efforts on
low carbon, energy conservation, supportive and safe (LESS)- in line with sustainable
development goals, thereby delivering significant benefits, including:V01/2019

We expect other related National Standards Bodies to join the new ISO/TC if created.
A listing of relevant external international organizations or internal parties (other ISOand/or IEC committees) to be engaged as liaisons in the development of thedeliverable(s). (In order to avoid conflict with, or duplication of efforts of, other bodies, it
is important to indicate all points of possible conflict or overlap. The result of any
communication with other interested bodies shall also be included.)
To be engaged as liaisons or to be kept informed during the development of the proposed newTC standards:
ISO/TC 11 Boilers and pressure vessels – STANDBY
TC 59/SC 17 Sustainability in buildings and civil engineering works
ISO/TC 86 Refrigeration and air-conditioning

A simple and concise statement identifying and describing relevant affected stakeholder
categories (including small and medium sized enterprises) and how they will each benefit
from or be impacted by the proposed deliverable(s).
This proposed work program would be designed to meet the needs of different stakeholders
including heat supply planners, regulators, utilities, companies, infrastructure companies,
service companies, and consumers for standardized terminology, technology and supporting
tools of HSN.
The standardization of HSN would also enhance ongoing international effort by the internationalorganizations and national governments to accelerate clean energy transition, infrastructure andetc. aligning with sustainable development goals.
More specifically, the proposal will support HSN providers to supply modern, clean andaffordable heat as a priority in their agenda of economic and social development.

It will also provide assurance to global stakeholders, particularly the related service providers
and consumers of the credibility of HSN technologies.
An expression of commitment from the proposer to provide the committee secretariat if
the proposal succeeds.
China will provide secretariat for this new TC if the proposal is approved.
Purpose and justification for the proposal. (The purpose and justification for the creationof a new technical committee shall be made clear and the need for standardization in thisfield shall be justified. Clause C.4.13.3 of Annex C of the ISO/IEC Directives, Part 1
contains a menu of suggestions or ideas for possible documentation to support andpurpose and justification of proposals. Proposers should consider these suggestions,but they are not limited to them, nor are they required to comply strictly with them. Whatis most important is that proposers develop and provide purpose and justification
information that is most relevant to their proposals and that makes a substantial businesscase for the market relevance and the need for their proposals. Thorough, well-developed
and robust purpose and justification documentation will lead to more informed
consideration of proposals and ultimately their possible success in the ISO IEC system.)
At present, on the one hand, human beings are actively responding to the threat and challenge
brought by extreme climate change, especially extreme cold weather, on the other hand, they
are actively promoting carbon reduction and net zero emission, and constantly building multidimensional sustainable development path such as society, economy and environment. Theseare the goals of the United Nations Sustainable Development and the direction of development
raised by the Paris Agreement. As one of the important factors, the quality improvement andefficiency of heating network can not be ignored.
The heating network is the pipeline system which efficiently transmit and distribute heat energy
from heat source to the users. The safety and normal operation of the heating network maintainthe normal production and life of urban and rural residents. With the development and applicationof information and communication technology, the composition and environment of modern
heating network are becoming more and more complex. As a vital infrastructure for theconstruction and development of modern life, heating network has also met the incentives andchallenges in economic, technological, social and environmental aspects, which will betransformed in this global transformation. We will carry out the standardization of heating network
to reduce heat transmission loss through the standardization of design, operation and productenergy-saving technology, to improve the compatibility and efficiency of industrial waste heat, toimprove the control and regulation level of heating pipe network, therefore help to achieve thegoal of low carbon, energy saving, supportive and safety.
With the establishment of large thermal power plants and nuclear power plants, the distance ofheat energy transmission is getting furtherer and furtherer, and the pipe diameter is alsoincreasing bigger and bigger. Therefore, countries generally adopt indirect heating system on alarge scale, and long-distance transmission pipelines with high temperature circulating water.
Berlin has built a combined network operation system including seven thermal power plants. A
combined network system has been built in Copenhagen, Denmark, including thermal power
plants, waste incineration plants and peak boiler rooms. The total length of heating network hasreached 392,9000 km in China. Technologies such as long-distance heat supply network, largescale heating transmission and distribution system by distributed water pump, direct-buried
pipeline laying, pipeline leakage detection based on distributed optical fiber are playing importantrole in the construction and operation of the heating network in China. With the emerging of newV01/2019

Form 1:Proposal for a new field of technical activity
Page 7technologies and new equipment, the compatibility of multi-type heat sources and heat users,
lower transmission loss and two-way operation network mechanism have become the newtendencies. Promote the development of heating network by standardization will not only
accelerate the sustainable industrialization and innovation, but also help to build inclusive, safeand disaster resistant infrastructure.
At present, there is no HSN directive related technical committees in ISO, IEC, or at the level ofinternational organizations. In addition, in the development of relevant standards for heating
network, technical committees related to "heating" in ISO, such as ISO/TC1 1 boiler andpressure vessel (suspension), ISO/TC 86 refrigeration and air conditioning, thermal performanceand energy utilization in ISO/TC 163 building environment, ISO/TC 205 architecturalenvironment design, ISO/TC 267 facility management, ISO/TC 268 sustainable cities andcommunities, ISO/TC 301 energy management and energy savings are not directly related tothe standardization of HSN. The standardization of HSN will be planned as a whole, and develop
more suitable standards for the actual, targeted and practical demand.
To carry out the standardization of HSN, we will ask for ISO family members’ support and invite
all related members to participate jointly and actively. By summarizing best practices, we will
promote the quality and efficiency of HSN, and we will achieve the goal of “ISO standards usedeverywhere” better, and support the realization of ISO 2030 strategy, Paris Agreement and thesustainable development goals of the United Nations.
