Technical Committee (TC) Environmental Engineering (EE) Activity Report 2019

Chair: Beniamino Gorini, Nokia

Responsible for defining the equipment engineering, the bonding and grounding, the 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 installations. Much of the committee’s work supports European Commission (EC) policies, regulations or legislation on eco-design aspects, where we liaise with the European Committee for Electrotechnical Standardization (CENELEC) to develop relevant standards. In particular we develop standards to support EC Mandate M/462 on efficient energy use in fixed and mobile information and communication networks. 

In 2019 our activities centred on 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.

We published two standards defining energy efficiency measurement metrics, methodology and KPIs – one for server equipment [EN 303 470] and the other [EN 303 471] for Network Function Virtualization (NFV) applications. The latter was accompanied by a new standard [ES 203 539] to measure NVF energy efficiency in a laboratory environment.

A new Technical Report [TR 103 679] explored the challenges of developing specific Product Environmental Footprint Category Rules (PEFCRs) for smartphones. 

We revised a further part of our standard [ES 202 336-12] for a monitoring and control interface for power, cooling and building environment systems used in telecommunication networks. In addition we revised standards [EN 300 132-1], [EN 300 132-2] covering power supply interfaces for ICT equipment.

Based on work with ITU-T SG5, we published the first part of a Technical Specification [TS 103 553-1] that explores innovative energy storage technology solutions for stationary ICT equipment in environments such as sustainable smart cities. We also published a further Technical Specification [TS 103 586] considering liquid cooling solutions for ICT infrastructure equipment.

We continued revisions of our environmental test standards to clarify expected performance criteria following the application of tests, and to adapt requirements in accordance with climate change aspects and IEC standards.
