27.015 - Energy efficiency. Energy conservation in general

IEC 63172:2020 provides a methodology for determining the energy efficiency class of electrical accessories, to enable the system designer to determine the most efficient components for an electrical installation, also considering all functionalities. This methodology is based on the energy consumption, taking into account the individual functions of the accessory. The energy efficiency class approach contributes to the overall reduction of the energy consumption of an electrical installation.

This document is a compilation of recommended Practices for improving the energy management (i.e. reduction of energy consumption and/or increases in energy efficiency) of data centres. It is historically aligned with the EU Code of Conduct for Data Centre Energy Efficiency (CoC) scheme operated by the Directorate-General Joint Research Centre (DG JRC) of the European Commission (EC).
It is recognized that the Practices included might not be universally applicable to all scales and business mod...view more

This EN specifies the so-called Energy Reuse Factor (ERF) as a KPI to quantify the reuse of the energy consumed in the data centre. The ERF does reflect the efficiency of the reuse process, however, the reuse process is not part of the data centre.

IEC 63252:2020 defines methods for the measurement of energy consumption of vending machines, whether or not fitted with refrigerating appliances.
The standard applies (but is not limited) to the following categories of machines:
- Refrigerated closed-fronted can and bottle machines where the products are held in stacks
- Refrigerated glass-fronted can and bottle, confectionery and snack machines
- Refrigerated glass-fronted machines entirely for perishable foodstuffs
- Refrigerated dual-te...view more

This document gives practical guidelines and examples for establishing, implementing, maintaining and improving an energy management system (EnMS) in accordance with the systematic approach of ISO 50001:2018. The guidance in this document is applicable to any organization. This document does not provide guidance on how to develop an integrated management system. While the guidance in this document is consistent with the requirements of ISO 50001:2018, it does not provide interpretations of those...view more

The present document defines the metrics and measurement methods for the energy efficiency of functional components
of NFV environment. The NFV functional components include Virtualised Network Functions (VNFs) and NFV
Infrastructure (NFVI) defined in NFV architecture framework as described in ETSI GS NFV 002 [i.1]. Management
and Orchestration (MANO) is not included as system under test, but will be eventually taken as test environment.
The measurement method described in the present docume...view more

This document specifies the methods of energy consumption measurement for container straddle carriers, as defined in ISO 5053-1:2015.
This document shall be used in conjunction with EN 16796-1, where the requirements of this part differ from that in part 1 – requirements in this part 4 will take precedent.

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 ...view more

IEC TR 63196:2020 is following the principles of IEC Guide 119. This document defines the energy efficiency aspects of switchgear and controlgear products complying with IEC 60947 (all parts), IEC 61095 and IEC 62626 (all parts), and associated assemblies complying with IEC 61439 (all parts), in the context of the overall system energy efficiency. This document references energy policy aspects, as well as product and system aspects.

This European Standard specifies a method for energy assessment of un-vented (closed) hot water storage tanks with a capacity up to 1 500 l, intended to be equipped with an external heat source and used for domestic hot water production. Whilst storage water heaters intended primarily for direct heating are not covered by this European Standard, it does allow the provision of electric heating elements for auxiliary use.

This document gives guidelines for how to compare and prioritize energy saving projects (EnSPs) before implementation, using economic and financial evaluation. It includes a common set of principles. This document is applicable to all EnSPs and energy performance improvement actions (EPIAs) that are developed by stakeholders and organizations for improving energy performance, irrespective of the type and size of an organization and its energy use and consumption. The methodology for quantificati...view more
