Heat Supply Network: ANSI Seeks Comments on Proposed New ISO Technical Committee


Submit Feedback by October 29, 2021

As the U.S. member body to the International Organization for Standardization (ISO), the American National Standards Institute (ANSI) is seeking comments on a proposal for a new ISO technical committee on "Heat Supply Network (HSN)."

About Heat Supply Networks

HSN, a distribution system of insulated pipes, can deliver cost effective heat from a central source to residential, public, and industrial buildings. According to the proposal, submitted by SAC, the ISO member for China, a holistic standards program for HSN at the ISO level will help to support global efforts on low carbon and energy conservation in line with sustainable development goals.

The proposed scope of the new ISO technical committee is "Standardization in the field of HSN including design, construction, integration, control and regulation based on heating supply pipeline system."

According to the proposal:

  • The standardization of HSN design, operation, and product energy-saving technology, would lead to the reduction of heat transfer loss.


  • The standardization of HSN safety technology would improve the operation reliability of heat supply networks.


  • The standardization of HSN can improve the compatibility and efficiency of industrial waste heat and renewable energy, and achieve the goal of green and low carbon.


  • With the standardization of HSN, Internet of things and information communication technology can improve the control and regulation level of heating pipe network.


  • Standardization can improve the mechanism and business model through HSN to promote the development of low-carbon economy.

The proposal notes that the work of the new ISO technical committee would focus first on the development of the following international standards:

  1. ISO “heat supply network: terminology”
  2. ISO “Guideline on designing heat supply network”
  3. ISO “Technical specification for the operation and maintenance of heat supply network”
  4. ISO “Basic requirement for control and regulation of heat supply network”

Review the proposal for additional information and submit comments to Steven Cornish, ANSI senior director of international policy and strategy, [email protected], by close of business on October 29, 2021. Based on input received from U.S. stakeholders, a recommended ANSI position and any comments will be developed and presented at the ANSI ISO Committee (AIC) for approval before ISO's voting deadline of December 8, 2021.

ANSI has published an explanatory information document outlining the process used to develop U.S. positions in issues and activities under consideration by ISO and IEC.
