Environmental Engineering (EE); Standardization terms and trends in energy efficiency
Environmental Engineering (EE); Standardization terms and trends in energy efficiency
The aim is develop a framework standard that will take into consideration all general aspects, terms and main trends towards energy efficiency/management, including but not limited to: New Standards dealing with this scope (e.g. future Standard under development or planned, Existing ETSI standard on energy efficiency, monitoring and KPis, Existing ITU-T Recommendations: ITU-T L.1310, L.1340 Other SDOs deliverable . The general part of the framework will provide general requirements such as definitions of common understanding of terms, clarification of energy efficiency definition for different types of technologies (e.g. equipment/site/network/service level) Part of the activity will cover test instrumentation specification
Okoljski inženiring (EE) - Standardizacijski izrazi in smernice na področju energetske učinkovitosti
Cilj je razvoj okvirnega standarda, v katerem bodo upoštevani vsi splošni vidiki, pogoji in glavni trendi v zvezi z energetsko učinkovitostjo/upravljanjem z energijo, med drugim vključno z naslednjim:
• novimi standardi, ki obravnavajo to področje uporabe (npr. prihodnji načrtovani standard ali standard v pripravi);
• obstoječim standardom ETSI o energetski učinkovitosti, nadzoru in KPI-jih;
• obstoječimi priporočili ITU-T: ITU-T L.1310, L.1340,
• drugim dokumentom o SDO-jih.
Splošni del okvirja bo zagotovil splošne zahteve, kot so definicije splošnega razumevanja izrazov, pojasnitev definicije energetske učinkovitosti za različne vrste tehnologij (npr. raven opreme/mesta/omrežja/storitve) ... Del dejavnosti bo obsegal specifikacije preskusnih instrumentov.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
active mode: For (small) networking equipment, this is the operational mode where all ports (WAN and LAN) are
connected, with at least one Wi-Fi connection, if a Wi-Fi function is available. (As defined in Recommendation ITU-T
L.1310 [i.1]).
energy: "The capacity for doing work". In the telecommunication systems, where the primary source of energy is
electricity, energy is measured in Joules. (As defined in Recommendation ITU-T L.1310 [i.1]).
functional unit: (Based on ISO 14040 [i.2]). A performance representation of the system under analysis. For example,
for transport equipment, the functional unit is the amount of Data transmitted, the distance over which it is transported
and its rate in Gbit/s. Sometimes the term is used to represent useful output or work. (As defined in Recommendation
ITU-T L.1310 [i.1]).
idle mode: For (small) networking equipment, this means the same as active mode, but with no user data traffic (it is
not zero traffic, as service and protocol supporting traffic are present) being used, although it is ready to be used (U1 in
routers part). (As defined in Recommendation ITU-T L.1310 [i.1]).
low power (sleep) mode: For small networking equipment, this means a state that happens after the device detects no
user activity for a certain period of time and reduces energy consumption. For this state, no user-facing LAN ports are
connected; the Wi-Fi is active but no clients are connected. The WAN port may be inactive. The device will reactivate
on detecting a connection from a user port or device. (As defined in Recommendation ITU-T L.1310 [i.1]).
small networking device: A networking device with fixed hardware configuration, designed for home/domestic or
small office use, with less than 12 wired ports. This device can have wireless functionality implemented. (As defined in
Recommendation ITU-T L.1310 [i.1]).

4.1 General concept
Energy Efficiency is a widely used term with multiple meanings, one can hear "use stairs, be energy efficient" Energy
efficient office or house or many others.
Since we are talking about electrical devices, efficiency definition could start from a generic definition for Energy
Efficiency for energy converting devices:
η= Energy / Energy (1)

"Energy Efficiency" that applies to any device that uses energy to do work: "Percentage of total energy input to a

Executive summary
The present document contains high level definition of energy efficiency, energy management requirement to increase
the energy efficiency of ICT goods/networks/services.
Introduction
The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5 and published respectively by
ITU and ETSI as Recommendation ITU-T L.1315 [i.3] and ETSI Standard ETSI ES 203 475, which are technically
equivalent.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
active mode: For (small) networking equipment, this is the operational mode where all ports (WAN and LAN) are
connected, with at least one Wi-Fi connection, if a Wi-Fi function is available. (As defined in Recommendation ITU-T
L.1310 [i.1]).
energy: "The capacity for doing work". In the telecommunication systems, where the primary source of energy is
electricity, energy is measured in Joules. (As defined in Recommendation ITU-T L.1310 [i.1]).
functional unit: (Based on ISO 14040 [i.2]). A performance representation of the system under analysis. For example,
for transport equipment, the functional unit is the amount of Data transmitted, the distance over which it is transported
and its rate in Gbit/s. Sometimes the term is used to represent useful output or work. (As defined in Recommendation
ITU-T L.1310 [i.1]).
idle mode: For (small) networking equipment, this means the same as active mode, but with no user data traffic (it is
not zero traffic, as service and protocol supporting traffic are present) being used, although it is ready to be used (U1 in
routers part). (As defined in Recommendation ITU-T L.1310 [i.1]).
low power (sleep) mode: For small networking equipment, this means a state that happens after the device detects no
user activity for a certain period of time and reduces energy consumption. For this state, no user-facing LAN ports are
connected; the Wi-Fi is active but no clients are connected. The WAN port may be inactive. The device will reactivate
on detecting a connection from a user port or device. (As defined in Recommendation ITU-T L.1310 [i.1]).
small networking device: A networking device with fixed hardware configuration, designed for home/domestic or
small office use, with less than 12 wired ports. This device can have wireless functionality implemented. (As defined in
Recommendation ITU-T L.1310 [i.1]).
