IEA 4E EDNA: Electronic Devices and Networks Annex (Working period 2022 - 2024)

By 2030, the number of network-connected electronic devices worldwide is expected to exceed 100 billion, resulting in significant consequences for global energy consumption. The IEA 4E Electronic Devices and Networks Annex - EDNA therefore aims to develop policy recommendations to promote the energy efficiency of network-connected devices, and make those project results available to key stakeholders such as policy makers and product developers in the form of reports, policy briefs and tools.

Short Description

The aim of EDNA is to support policy makers to develop and introduce regulations for network-connected devices and thus contribute to the energy efficiency of these devices and systems. The ECODESIGN company GmbH (ECO) represents the Austrian Federal Ministry for Climate Protection, Environment, Energy, Mobility, Innovation and Technology (BMK) in this Annex to position Austrian interests in this international research collaboration.

Since the funding of the Annex, various tasks and projects have been established, to explore and analyze opportunities and barriers for the promotion of energy-efficient measures, and to develop policy recommendations made on this basis. During the coming period, the Annex will focus on the following product groups: 

  • Data centres (Task 23),
  • Mobile devices (Task 24) and
  • Battery technologies (Task 25).

In addition, the emphasis is on developing and formulating policy recommendations that go beyond products and address device interoperability (Task 26) and standardization (Task 27).

EDNA is extending its previous work in Task 23 to create a program on energy efficiency of servers and data centres, as the topic requires new activities with a strategic direction, and is being planned in consultation with the EDNA country delegates. EDNA is also evaluating the establishment of a task on "Blockchain - Energy use and energy efficiency", building on the work carried out by some of its members on this topic.

The existing EDNA Centre of Excellence will continue with the aim of expanding the documentation on energy efficiency studies, strategies and measures in the area of network-connected devices and intelligent efficiency, as well as to increase the collaboration work with stakeholders from industry.
