Proposal for creation of new ISO Technical Committee District Energy System

ISO Central Secretariat received a proposal from Standardization Administration of China - SAC for the creation of an ISO Technical Committee in the area of

Scope statement of the proposed new committee

Standardization of planning, operation, maintenance, optimization and application of the integrated district energy system with multiple energy carriers. Excluding: specific energy (electricity or non-electricity) technologies, information technologies or control technologieswithin the scope of other ISO or IEC/TCs.

Purpose and justification for the proposal The proposed TC will bring forward a holistic approach of standardization using “systems thinking” to overcome the silos among existing TCs of technologies or sectors related to DES. Standardization of integrated DES will allow different networks to function and interact with one another in a reliable and user-friendly manner. For example, linking the heat and electricity sectors through district energy infrastructure and utilizing low-grade energy sources, such as waste heat from industry or free cooling, can greatly improve the operational efficiency.

Accelerating the uptake of energy efficiency and renewable energy in the global energy mix is the single biggest contribution to keep global temperature rise under 2 degrees Celsius (°C) and to reap the multiple benefits of an inclusive green economy. The development of modern and affordable district energy systems is one of the least-cost and most-efficient solutions for reducing greenhouse gas emissions and primary energy demand. A transition to such systems, combined with energy efficiency measures, could contribute as much as 58 per cent of the carbon dioxide (CO2) emission reductions required in the energy sector by 2050. In the EU Strategy for Energy System Integration, it is suggested to facilitate the reuse of waste heat from industrial sites and accelerate investment in smart, highly-efficient, renewables-based district heating and cooling networks. It is also emphasized energy system integration will also strengthen the competitiveness of the European economy by promoting more sustainable and efficient technologies and solutions including district heating system across industrial ecosystems related to the energy transition, their standardisation and market uptake

Proposed initial programme of work. Modern district energy system (DES) creates synergies between the production and supply of heat, cooling, domestic hot water and electricity across multiple energy carriers and consumers, with the goal of optimizing energy efficiency and local resource use in line with the Paris Agreement and the UN’s 2030 Agenda for Sustainable Development

As a priority and to lead the programme, a Guidance on Planning District Energy System will be developed to agree common terminology, and provide practical guidance on principles and practices that embed integrated and holistic consideration. It will provide examples of good practice, as well as implementation guidance on the different district energy systems using technologies and approaches such as combined cooling, heating and power (CCHP), heat pumps, energy storage and decentralized energy. The standard will bring a wider, more holistic umbrella for whole family of standards for DES.

Potentional stakeholders Industry, government, customers, suppliers, contractors, consumers, academic institutions, testing evaluation agencies and trade associations.

In case of national interest, Bulgaria can support the creation of this ISO/TC „Deoxidizers and desiccants”. If the establishment of ISO/TC is accepted by the national standards bodies – members of ISO, BDS can obtain P- or O-membership in the work of the newly established committee.

The national stakeholders can provide their position on the proposal by 05.07.2021 to Rozalina Haladzhova: rozalina.haladzhova@bds-bg.org, tel: +359 2 81 74 569.
