Access, Terminals, Transmission and Multiplexing (ATTM) - Energy management - Operational infrastructures - Global KPIs - Part 3: ICT Sites - Sub-part 1: DCEM

The present document specifies the requirements for a Global KPI for energy management (KPIDCEM) and their
underpinning Objective KPIs addressing the following objectives for the ICT sites of broadband deployment:
• energy consumption;
• task effectiveness;
• energy reuse;
• renewable energy.
KPIDCEM is a simplified version of the KPIEM of ETSI EN 305 200-2-1 [i.13] and the requirements are mapped to the
general requirements of ETSI EN 305 200-1 [i.12].
Energy management of ICT sites comprises a number of independent layers. The present document addresses
performance of infrastructures that supports the normal function of hosted ICT equipment (e.g. power distribution,
environmental control, security and safety). The present document does not address other layers such as performance of
ICT equipment itself, performance of usage of available processing power, and layers related to final service delivered
(e.g. processing power required per itemized outcome) or overlay layers (e.g. energy consumption per itemized
outcome).
The environmental impact and management of different energy sources are outside the scope of the present document.
Within the present document:
• clause 4 describes the energy parameters for ICT sites together with inclusions/exclusions of different energy
contributions;
• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPIDCEM.

Dostop, terminali, prenos in multipleksiranje (ATTM) - Upravljanje z energijo - Operativna infrastruktura - Globalni ključni kazalniki uspešnosti (KPI) - 3. del: Strani ICT - 1. poddel: DCEM

Ta dokument določa zahteve za globalni KPI za upravljanje z energijo (KPIDCEM) in njegove temeljne ciljne KPI-je, ki naslavljajo naslednje cilje za mesta IKT za širokopasovno uporabo:
• poraba energije;
• učinkovitost opravil;
• ponovna uporaba energije;
• obnovljiva energija.
KPIDCEM je poenostavljena različica KPIEM v standardu ETSI EN 305 200-2-1 [i.13] in zahteve so preslikane v splošne zahteve standarda ETSI EN 305 200-1 [i.12].
Upravljanje z energijo mest IKT je sestavljeno iz več neodvisnih slojev. Ta dokument naslavlja učinkovitost infrastruktur, ki podpirajo običajno delovanje gostujoče opreme IKT (npr. distribucija električne energije, okoljski nadzor, zaščita in varnost). Ta dokument ne naslavlja drugih slojev, kot so učinkovitost same opreme IKT, učinkovitost uporabe razpoložljive zmogljivosti procesorja in sloji, povezani s končno dostavljeno storitvijo (npr. potrebna moč obdelave glede na rezultat po elementih) ali prekrivni sloji (npr. poraba energije glede na rezultat po elementih).
Učinek na okolje in upravljanje različnih virov energije ne spadata na področje uporabe tega dokumenta.
V tem dokumentu:
• točka 4 opisuje energijske parametre za mesta IKT, skupaj z vključitvami/izključitvami različnih energetskih prispevkov;
• točka 5 določa zahteve za merjenje, izračun, razvrstitev in poročanje za KPIDCEM.

ETSI ETSI EN 305 200-3-1 V1.1.1 (2018-02)8 Introduction Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new active equipment to the network architecture. In this context, and to reflect other environmental aspects of sustainability, it is vital that the main telecommunication operators implement effective general engineering of fixed and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to respond to critical issues of energy consumption while proposing essential solutions to broadband deployment. To guide this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable energy usage to be managed more effectively.

The Global Key Performance Indicators specified in the ETSI EN 305 200 [i.11] series address operational infrastructures and do not consider design or operation of individual components comprising those infrastructures. ETSI EN 305 200 [i.11] series of standards comprises: • ETSI EN 305 200-1 [i.12] a generic requirements document addressing Global KPIs for operational infrastructures; • a sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for specific operational networks and sites and which describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives): - ETSI EN 305 200-2-1 [i.13]: ICT sites; - ETSI EN 305 200-2-2 [i.14]: Fixed broadband access networks; NOTE:

Excluding cable access networks. - ETSI EN 305 200-2-3 [i.15]: Mobile broadband access networks. The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain information on values that have been used by certain organizations. • a sub-series ETSI EN 305 200-3 including the present document (which replaces ETSI ES 205 200-3) that defines particular implementations of Global KPIs within ICT sites based on the requirements of ETSI EN 305 200-2-1 [i.13], and which may define levels of performance to simplify and provide clearer understanding of Global KPIs allowing the evaluation of performance of energy use management in ICT sites. The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain information on values that have been used by certain organizations. • a sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4 [i.16] that defines design assessments of Global KPIs, and drives energy management targets, for specific operational networks and sites and which describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives). These standards may be considered to be a contribution to the application of ISO 50001 [i.17] in relation to the development of policy for the continuous improvement of energy management and will accelerate: • the availability of operational infrastructure architectures and network implementations that use energy more efficiently; • the definition and attainment objectives for other environmental aspects of sustainability for operational broadband networks. The present document specifies the requirements for a Global KPI for energy management (KPIDCEM) and their underpinning Objective KPIs for the ICT sites of broadband deployment which is a simplified version of the KPIEM of ETSI EN 305 200-2-1 [i.13]. The requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.12]. SIST EN 305 200-3-1 V1.1.1:2018

ETSI ETSI EN 305 200-3-1 V1.1.1 (2018-02)9 1 Scope The present document specifies the requirements for a Global KPI for energy management (KPIDCEM) and their underpinning Objective KPIs addressing the following objectives for the ICT sites of broadband deployment: • energy consumption; • task effectiveness; • energy reuse; • renewable energy. KPIDCEM is a simplified version of the KPIEM of ETSI EN 305 200-2-1 [i.13] and the requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.12]. Energy management of ICT sites comprises a number of independent layers. The present document addresses performance of infrastructures that supports the normal function of hosted ICT equipment (e.g. power distribution, environmental control, security and safety). The present document does not address other layers such as performance of ICT equipment itself, performance of usage of available processing power, and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers (e.g. energy consumption per itemized outcome). The environmental impact and management of different energy sources are outside the scope of the present document. Within the present document: • clause 4 describes the energy parameters for ICT sites together with inclusions/exclusions of different energy contributions; • clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPIDCEM. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

Introduction

Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new

active equipment to the network architecture. In this context, and to reflect other environmental aspects of

sustainability, it is vital that the main telecommunication operators implement effective general engineering of fixed

and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to

respond to critical issues of energy consumption while proposing essential solutions to broadband deployment. To guide

this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable

energy usage to be managed more effectively.

The Global Key Performance Indicators specified in the ETSI EN 305 200 [i.11] series address operational

infrastructures and do not consider design or operation of individual components comprising those infrastructures.

ETSI EN 305 200 [i.11] series of standards comprises:

• ETSI EN 305 200-1 [i.12] a generic requirements document addressing Global KPIs for operational

infrastructures;

• a sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for

specific operational networks and sites and which describes how the Global KPIs are to be applied (which may

be used to support future regulatory objectives):
- ETSI EN 305 200-2-1 [i.13]: ICT sites;
- ETSI EN 305 200-2-2 [i.14]: Fixed broadband access networks;
NOTE: Excluding cable access networks.
- ETSI EN 305 200-2-3 [i.15]: Mobile broadband access networks.

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-3 including the present document (which replaces ETSI ES 205 200-3) that

defines particular implementations of Global KPIs within ICT sites based on the requirements of ETSI

EN 305 200-2-1 [i.13], and which may define levels of performance to simplify and provide clearer

understanding of Global KPIs allowing the evaluation of performance of energy use management in ICT sites.

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4 [i.16] that defines design assessments of

Global KPIs, and drives energy management targets, for specific operational networks and sites and which

describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives).

These standards may be considered to be a contribution to the application of ISO 50001 [i.17] in relation to the

development of policy for the continuous improvement of energy management and will accelerate:

• the availability of operational infrastructure architectures and network implementations that use energy more

efficiently;

• the definition and attainment objectives for other environmental aspects of sustainability for operational

broadband networks.

The present document specifies the requirements for a Global KPI for energy management (KPI ) and their

DCEM
of

underpinning Objective KPIs for the ICT sites of broadband deployment which is a simplified version of the KPI

ETSI EN 305 200-2-1 [i.13]. The requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.12].

1 Scope

The present document specifies the requirements for a Global KPI for energy management (KPI ) and their

DCEM

underpinning Objective KPIs addressing the following objectives for the ICT sites of broadband deployment:

• energy consumption;
• task effectiveness;
• energy reuse;
• renewable energy.

KPI is a simplified version of the KPI of ETSI EN 305 200-2-1 [i.13] and the requirements are mapped to the

DCEM EM
general requirements of ETSI EN 305 200-1 [i.12].

Energy management of ICT sites comprises a number of independent layers. The present document addresses

performance of infrastructures that supports the normal function of hosted ICT equipment (e.g. power distribution,

environmental control, security and safety). The present document does not address other layers such as performance of

ICT equipment itself, performance of usage of available processing power, and layers related to final service delivered

(e.g. processing power required per itemized outcome) or overlay layers (e.g. energy consumption per itemized

outcome).

The environmental impact and management of different energy sources are outside the scope of the present document.

Within the present document:

• clause 4 describes the energy parameters for ICT sites together with inclusions/exclusions of different energy

contributions;

• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPI .

Introduction

Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new

active equipment to the network architecture. In this context, and to reflect other environmental aspects of

sustainability, it is vital that the main telecommunication operators implement effective general engineering of fixed

and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to

respond to critical issues of energy consumption while proposing essential solutions to broadband deployment. To guide

this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable

energy usage to be managed more effectively.

The Global Key Performance Indicators specified in the ETSI EN 305 200 [i.11] series address operational

infrastructures and do not consider design or operation of individual components comprising those infrastructures.

ETSI EN 305 200 [i.11] series of standards comprises:

• ETSI EN 305 200-1 [i.12] a generic requirements document addressing Global KPIs for operational

infrastructures;

• a sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for

specific operational networks and sites and which describes how the Global KPIs are to be applied (which may

be used to support future regulatory objectives):
- ETSI EN 305 200-2-1 [i.13]: ICT sites;
- ETSI EN 305 200-2-2 [i.14]: Fixed broadband access networks;
NOTE: Excluding cable access networks.
- ETSI EN 305 200-2-3 [i.15]: Mobile broadband access networks.

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-3 including the present document (which replaces ETSI ES 205 200-3) that

defines particular implementations of Global KPIs within ICT sites based on the requirements of ETSI

EN 305 200-2-1 [i.13], and which may define levels of performance to simplify and provide clearer

understanding of Global KPIs allowing the evaluation of performance of energy use management in ICT sites.

The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain

information on values that have been used by certain organizations.

• a sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4 [i.16] that defines design assessments of

Global KPIs, and drives energy management targets, for specific operational networks and sites and which

describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives).

These standards may be considered to be a contribution to the application of ISO 50001 [i.17] in relation to the

development of policy for the continuous improvement of energy management and will accelerate:

• the availability of operational infrastructure architectures and network implementations that use energy more

efficiently;

• the definition and attainment objectives for other environmental aspects of sustainability for operational

broadband networks.

The present document specifies the requirements for a Global KPI for energy management (KPI ) and their

DCEM
of

underpinning Objective KPIs for the ICT sites of broadband deployment which is a simplified version of the KPI

ETSI EN 305 200-2-1 [i.13]. The requirements are mapped to the general requirements of ETSI EN 305 200-1 [i.12].

1 Scope

The present document specifies the requirements for a Global KPI for energy management (KPI ) and their

DCEM

underpinning Objective KPIs addressing the following objectives for the ICT sites of broadband deployment:

• energy consumption;
• task effectiveness;
• energy reuse;
• renewable energy.

KPI is a simplified version of the KPI of ETSI EN 305 200-2-1 [i.13] and the requirements are mapped to the

DCEM EM
general requirements of ETSI EN 305 200-1 [i.12].

Energy management of ICT sites comprises a number of independent layers. The present document addresses

performance of infrastructures that supports the normal function of hosted ICT equipment (e.g. power distribution,

environmental control, security and safety). The present document does not address other layers such as performance of

ICT equipment itself, performance of usage of available processing power, and layers related to final service delivered

(e.g. processing power required per itemized outcome) or overlay layers (e.g. energy consumption per itemized

outcome).

The environmental impact and management of different energy sources are outside the scope of the present document.

Within the present document:

• clause 4 describes the energy parameters for ICT sites together with inclusions/exclusions of different energy

contributions;

• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPI .
