The present document version covers base stations with the following radio access technologies:
• GSM.
• WCDMA.
• LTE.
• NR.
The methodology described in the present document is to measure base station static power consumption and RF output
power. Within the present document it is referred to as static measurements.
The results based on "static" measurements provide power and energy consumption figures for BS under static load.
Energy consumption of terminal (end-user) equipment is outside the scope of the present document.
The scope of the present document is not to define target values for the BS power and energy consumption.
The results should only be used to assess and compare the power and energy consumption of complete base stations.
Wide Area Base Stations and Medium Range Base Stations (as defined in ETSI TS 125 104 [2], ETSI TS 136 104 [12],
and ETSI TS 138 104 [15]) are covered in the present document.

The present document is aimed at defining the topology and level of analysis to assess the energy efficiency of mobile
networks. Within the scope of the present document there is the radio access part of the mobile networks, and namely
there are radio base stations, backhauling systems, radio controllers and other infrastructure radio site equipment. The
covered technologies are GSM, UMTS, LTE and 5G New Radio (NR). In particular the present document defines
metrics for mobile network energy efficiency and methods for assessing (and measuring) energy efficiency in
operational networks. The purpose of the present document is to allow better comprehension of networks energy
efficiency, in particular considering the networks' evolution in different periods in time.
Aiming to consider also the slicing approach of the networks from 5G onwards the metrics are extended to the latency
of the network itself related to the energy consumed, additionally to the metrics based on traffic and on coverage,
already existing for legacy networks and still valid.
The present document deals with both a homogeneous and heterogeneous "network" considering a network whose size
and scale could be defined by topologic, geographic or demographic boundaries. For networks defined by topologic
boundaries, a possible example of a network covered by the present document consists of a control node (whenever
applicable), its supported access nodes as well as the related network elements. Networks could be defined by
geographic boundaries, such as city-wide, national or continental networks and could be defined by demographic
boundaries, such as urban or rural networks.
The present document applies to the so-called "partial" networks for which a measurement method is also
recommended. The specification extends the measurements in partial networks to wider so-called "total" networks
energy efficiency estimations (i.e. the network in a geographic area, the network in a whole country, the network of a
MNO, etc.).
Terminal (end-user) equipment is outside the scope of the present document and is not considered in the energy
efficiency measurement.

This document defines a methodology for determining and assessing the energy efficiency of Waste Water Treatment Plants (WWTP). The methodology aims at describing, in a systematic way, the various steps required to establish the Water Treatment Energy Index (WTEI) of a particular WWTP.
The methodology includes the classification of WWTPs in different types, identification of different stages of treatment, identification of key performance indicators (KPIs), overview of existing energy monitoring standards and the detailed description of the methodology, including a step by step guideline of how to apply and implement it.
The methodology is divided in 2 sub-methods that should be selected and followed according to the following goals:
-   The Rapid Audit (RA) method allows for a quick estimation of the water treatment energy index (WTEI) based on existing information such as historical data pertaining to energy use records along with influent and effluent quality values. The aim of this methodology is to provide a WWTP energy benchmark, a rapid tool to identify energy efficiencies and inefficiencies so further actions can be planned, as well as to evaluate the impact of WWTP retrofitting.
The Rapid Audit methodology is detailed step by step in Clause 3 of this TR and can be used as a standalone document.
-   The Decision Support (DS) method requires intensive monitoring across a WWTP of energy usage and water quality parameters that provides an accurate and detailed calculation of WTEI for each stage as well as its overall value for the plant. The goal of this assessment is to serve as a diagnosis of the functions/equipment in a plant that may lead to poor energy efficiency performance.
The Decision Support methodology is detailed step by step in Clause 4 of this TR and can be used as a standalone document.

The purpose of this document is to provide requirements for equipment to be used in energy
efficiency systems. This document covers load-shedding equipment (LSE).
Guidelines relating to safety for LSE as given in IEC Guide 110 have been followed.
This document applies to load-shedding equipment for household and similar uses. The loadshedding
function is used in energy management systems to optimize the overall use of
electrical energy including production and storage. Load-shedding can be used for example
for energy efficiency purposes as per IEC 60364-8-1:2019.
This document applies to LSE for operation under normal conditions:
– AC circuits with a rated frequency of 50 Hz, 60 Hz or both, with a rated voltage not
exceeding 440 V (between phases), a rated current not exceeding 125 A and a rated
short-circuit capacity not exceeding 25 000 A; or
– DC circuits1.
LSEs are intended to control the energy supplied to one or more load, circuit or mesh when:
– defined conditions of time and current are reached;
– a command or information from an external system is received.
An LSE is intended to serve as:
– a single equipment having all the necessary means able to control the loads (e.g. the
electrical energy management function is embedded in such an equipment); or
– a unit integrated into a more complex equipment or an independent equipment being part
of an electrical energy management system (EEMS); or
– an assembly of independent equipment forming an LSE (e.g. an LSE with external current
sensors); or
– as a combination of the above points.
LSE can have a wireless interface.
LSE is part of the fixed installation.
NOTE 1 This document covers load shedding equipment in the fixed installations including portable appliances
connected thereto.
LSE are intended for use in circuits with protection against electrical shock and over-current
according to IEC 60364 (all parts).
NOTE 2 For example, fault protection (indirect contact protection) can be covered as follows:
– in TT systems, by an upstream RCBOs or RCCBs according to IEC 61008-1 and IEC 61009-1;
– in a TN system, by an upstream over-current protective device.
LSEs do not, by their nature, provide an isolation function nor the over-current protection.
LSEs are normally installed by instructed persons (IEC 60050-195:1998, 195-04-02) or skilled
persons (IEC 60050-195:1998, 195-04-01) and normally used by ordinary persons
(IEC 60005-195:1998, 195-04-03).
This document contains all requirements necessary to ensure compliance with the operational
characteristics required by type tests for LSEs based on single equipment or based on an
assembly of independent equipment.
These requirements apply for standard conditions of temperature and environment as given
in 5.1. They are applicable to LSEs with a degree of protection of IP 20 intended for use in an
environment with pollution degree 2. For LSE having a degree of protection higher than IP 20
according to IEC 60529, for use in locations where arduous environmental conditions prevail
(e.g. excessive humidity, heat or cold or deposition of dust) and in hazardous locations (e.g.
where explosions are liable of occur), special construction can be required.
If other functions are included in LSE, these functions are covered by the relevant standards.
This document does not address communication aspects such as protocols, interoperability,
data security and any other related aspects.

This document gives general technical guidelines for evaluating energy savings of thermal power plants before and/or after implementing energy performance improvement action(s) (EPIAs). It includes evaluation, unit component efficiency, indexes calculation, analyses and reporting. This document is applicable to existing thermal power generating units (TPGUs), where fossil fuels (e.g. coal, oil, natural gas) are combusted to generate electricity only or to supply thermal energy with the additional production of electricity (i.e. combined cycle power plants). NOTE A typical thermal power plant encompasses at least one TPGU. If there is more than one, the TPGUs can run independently. Results obtained in accordance with this document can be used either to evaluate the potential of energy savings or to determine fulfilment of contract guarantees. They do not provide a basis for comparison of the energy savings between TPGUs. This document does not prescribe performance tests or measurements for TPGU equipment components/systems, the sampling and analysis of the fuels used, substances added for control of emissions (e.g. halide, limestone) and by-products (e.g. ash, gypsum), and instruments to be employed, but it does specify parameters of interest in the determination of energy savings. Applicable procedures can be found in relevant documents (published or to be published).

This document specifies general methods for the calculation of predicted energy savings (PrES), using measure-based calculation methods, also known as bottom-up or energy performance improvement actions (EPIAs)-based methods (see ISO 17742). Indicator-based methods (see ISO 17742) and total-consumption-based methods (see ISO 50047) are not included in the scope of this document. This document provides general principles for categorizing and choosing the method, taking account of the context, targeted accuracy and resources available for calculating the PrES. It also provides guidance on the conditions for ensuring the quality of the PrES, their documentation and validation. It is applicable to calculation of PrES for any: — type of EPIA; — end-use sector; — energy end-use; — level of aggregation of energy savings; — stakeholder. NOTE 1 Stakeholders can include private or public organizations, energy auditors, energy services companies, energy and equipment suppliers, policy makers, etc. This document considers PrES from: — an EPIA; and/or — an action plan, programme or policy (aggregated energy savings). NOTE 2 An action plan, programme or policy can be implemented at different scales (organization, city, region, country). This document describes how to calculate PrES over a prediction period. It can be used to calculate PrES in terms of primary energy or final (or delivered) energy (as defined in ISO 50047 and ISO/IEC 13273-1).

IEC 60364-8-1:2019 provides additional requirements, measures and recommendations for the design, erection and verification of all types of low-voltage electrical installation including local production and storage of energy for optimizing the overall efficient use of electricity. It introduces requirements and recommendations for the design of an electrical installation within the framework of an energy efficiency management approach in order to get the best permanent functionally equivalent service for the lowest electrical energy consumption and the most acceptable energy availability and economic balance. These requirements and recommendations apply, within the scope of the IEC 60364 series, for new installations and modification of existing installations. This standard is applicable to the electrical installation of a building or system and does not apply to products. The energy efficiency of these products and their operational requirements are covered by the relevant product standards. This standard does not specifically address building automation systems.
This edition includes the following significant technical changes with respect to the previous edition:
a) revision of Annex B;
b) revision of 4.2: Energy efficiency assessment for electrical installations;
c) update of 8.3: Input from loads, sensors and forecasts;
d) introduction of new definitions.
This group energy efficiency publication is primarily intended to be used as an energy efficiency standard for the low voltage electrical installations mentioned in Clause 1, but is also intended to be used by technical committees in the preparation of standards, in accordance with the principles laid down in IEC Guide 119 and IEC Guide 118.
The contents of the corrigendum of May 2019 have been included in this copy.

The present document specifies the method and metrics to determine the energy efficiency of operational Network
Function Virtualisation (NFV) applications and their associated infrastructure when that infrastructure is implemented
outside the boundaries of the access fixed, cable and mobile networks which they serve.
The present document:
• Extends the Objective KPIs of ETSI EN 305 200-2-2 [i.2] (fixed access networks) and ETSI
EN 305 200-2-3 [i.3] (mobile access networks) to assess the impact of NFV when applied to those networks as
described in ETSI GR NFV 001 [i.4].
• Does not consider any assessment of energy saved by the implementation of NFV as there can be no timestamped
comparison of an operational infrastructure from which functions have been removed to a virtualized
environment.
NOTE: In an ICT network (e.g. a fixed access network) comprising many Network Distribution Nodes (NDNs)
with different loading levels it is not clear that there will always be an energy consumption benefit - the
more relevant benefit being network and operational flexibility (such as reduced maintenance or increased
reliability).
The present document:
• Does not address the operational energy efficiency of specific Information Technology Equipment (ITE) such
as servers which may provide NFV facilities. Other ETSI EN documents (e.g. ETSI EN 303 470 [i.1]) have
been prepared to address such factors.
• Does not specify any assessment of the overall effectiveness of an NFV implementation although it contains
information in an informative annex regarding the technical milestones that would be required for this to be
addressed in a future revision of the present document.
The KPIs specified are primarily intended for trend analysis - not to enable comparison between individual
implementations of NFV unless the conditions of operation are "similar".

This document gives guidelines for how the energy management team (EnMT) in an organization can define, request and regularly access the data and information needed to implement an energy management system (EnMS) designed to continually improve energy performance in buildings. It is applicable to data provided by human processes or by building automation, control, information technology, or even accounting systems. If the building information system (BIS) is accessible by the EnMT, the BIS can facilitate the provision of data and information. This could include data used in determining significant energy uses (SEUs), managing to improve energy performance (including energy consumption, energy use and energy efficiency) through to the use of energy performance indicators (EnPIs). This document does not apply to: — residential or industrial buildings; — buildings containing an industrial process where the industrial processes cannot be separated from other uses. However, many of the principles in this document can be applied to these or other types of buildings. NOTE Industrial processes can include manufacturing, packaging, transportation, assembly, etc. It does not apply to building automation data communication protocols themselves. It is does not consider the selection of energy management software, hardware and control algorithms for automatically managing buildings.
