Technical Committee (TC) Environmental Engineering (EE) Activity Report 2021

Chair: Beniamino Gorini, Nokia

Responsible for defining equipment engineering, bonding and grounding, power supply interface and environmental aspects for telecommunication infrastructures and equipment.

ETSI’s Environmental Engineering Committee (TC EE) manages various engineering aspects of telecommunication equipment in different types of installation. These include climatic, thermal, and other environmental conditions; physical requirements of equipment racks and cabinets; power supplies and grounding; Circular Economy (including lifecycle analysis) and energy performance measurement and assessment methods for different parts of radio access networks including data centres. The committee’s work also embraces innovative energy storage technologies for ICT equipment – for example to provide resilience in sustainable smart cities.

Much of our work supports European Commission (EC) policies, regulation, and legislation on eco-design aspects, where we liaise with the European Committee for Electrotechnical Standardization (CENELEC) and CEN to develop relevant standards. The committee is also in continuous interaction with ITU-T SG5 for the production of technically aligned deliverables.

During 2021 activities continued to address three key areas: measurement methods for the energy efficiency of ICT equipment with a focus on 5G; standardization terms and trends; and energy-aware networking measurement methods.

EE

In relation to Regulation (EU) 801/2013 on networked standby power consumption, we revised our Harmonised Standard EN 303 423 on measurement of standby consumption of interconnecting household and office electrical and electronic equipment. This was subsequently submitted to the EC, with the anticipation of citation in the OJEU.

EE 01

Our Working Group EE 01 continuing to revise environmental test standards to clarify expected performance criteria, following the application of the tests and to adapt the requirements with climate change aspects and with IEC standards.

We revised a further subpart of our multi-part European Standard on environmental conditions and environmental tests for telecommunications equipment. EN 300 019-2-5 covers ground vehicle installations. Work meanwhile neared completion on updates to further parts of this multi-part deliverable.

We also published a revision to our Technical Specification TS 103 586 on liquid cooling solutions for Technology ICT infrastructure equipment.

See the list of current EE 01 Work Items here.

EE 02

Work continued on the series of standards addressing the power supply interface requirements for ICT equipment.  We published a revision to the third part of our multi-part European Standard EN 300 132-3 V2.2.1 on power supply interface at the input of ICT equipment, concerning an interface up to 400V DC. Revision of other parts is ongoing. Furthermore, we published an update to our European Standard EN 302 099 V2.2.1 on the requirements for ICT equipment powered by a 400V AC source, covering reverse powering handshake and 400 VDC remote powering and power back-up. 

We published the second part of our multipart Technical Specification TS 103 553-2 on the evolution of battery technology for use with stationary ICT equipment.

The future development of 5G networks may see a significant increase in the density of radio cells, creating the need for smart, environmentally friendly new powering solutions. We accordingly published a new ETSI Standard ES 203 700 that defines sustainable power feeding solutions for 5G networks and equipment. The standard addresses the requirements of different solutions and equipment on power feeding structures, components, backup solutions and environmental condition.

EE EEPS

Our EEPS Working Group creates environmental efficiency standards for radio access networks, including ICT products that are part of network infrastructure. In 2021 this work included revision of the first part of our ETSI Standard ES 202 706-1 V1.6.1 on metrics and measurement methods for energy efficiency of wireless access network equipment.

EEPS together with CEN and CENELEC joint group 10, prepared for presentation to the EC of a Joint work programme for standardisation request M/573 in support of Regulation (EU) 2019/424 as regards ecodesign requirements for servers and data storage products, including from EE side, besides deliverables already published, Candidate Harmonized Standards EN 303 804 “Energy Efficiency metrics and measurement methods for data storage equipment”, EN 303 470 “Energy Efficiency measurement methodology and metrics for servers” and EN 303 800 series “Assessment of material efficiency of ICT network infrastructure goods” currently in drafting stage.
