Industry Specification Group (ISG) on Operational energy Efficiency for Users (OEU) Activity Report 2023

Chair: Dominique Roche, eG4U

Developing specifications for environmentally efficient Information and Communications Technologies (ICT).

ETSI’s Industry Specification Group on Operational energy Efficiency for Users (ISG OEU) is addressing operational eco-efficient Information and Communications technologies (ICT), including the power consumption and greenhouse gas emissions related to infrastructure, equipment and software within ICT sites (e.g. data centres, central offices) and networks.

The group brings together ICT professionals from a broad cross-section of European industries including the aeronautical and automotive sectors, banking, insurance and smart cities. ISG OEU collaborates with ETSI’s Access, Terminals, Transmission and Multiplexing (TC ATTM), Environmental Engineering (TC EE), eHEALTH and SmartM2M committees, and benefits from its involvement in the work of the European Commission (EC), specifically DG Growth and DG Communications Networks, Content and Technology (CNECT).

Activities carried out by ISG OEU aim are focused on:

  • Definition of users’ requirements that are provided to ETSI TCs for development of necessary standards.
  • Development of reference specifications to define sustainable levels of ICT elements (e.g. sites, parts of network).

ISG OEU supports work conducted on the basis of the former European Commission (EC) Mandate M/462 on efficient energy use in fixed and mobile information and communication networks.

 During 2023 the group neared completion of a new Group Report that considers data interoperability format with applications for connected buildings. To be published as GR OEU 035, the report describes opportunities for use of the opendthX format to produce a ‘digital twin’ applied in the context of the operation of connected buildings. Publication is anticipated in early 2024.

 In 2024, the group will work on a new Group Report on a methodology for using applicable ETSI standards in a context of openness to interoperability of systems and services deployed in so-called smart territories.

The group started in 2023 to study the implementation in smart buildings of best IT practices – adapted, supervised and secure, with a predominant logic of energy saving and minimization. It is anticipated this work will enable the development of a new Group Report on the topic.

During the year, the group continued to support ETSI’s active participation in the CEN-CENELEC-ETSI Coordination Group on Smart Grid (CG SG).
