EN 16231:2012 (E) 4 Introduction The overall aim of this European standard is to provide organisations with a methodology for collecting and analysing energy data with the purpose of establishing and comparing energy efficiency between or within entities. It may lead to reductions in total energy consumption by showing improvement opportunities and consequently possible reductions in costs and emissions of carbon dioxide. This standard addresses the general aspects of benchmarking. This does not include the definition and establishment of sector specific benchmarks. Energy efficiency benchmarking may be motivated by different needs, among which are: — awareness of energy performance levels of peers to trigger energy efficiency improvement actions; — definition of energy performance objectives; — knowledge and follow up of the energy performance of a group and the related (best) practices. Energy efficiency benchmarking applies to specific energy consumption whereby other performance aspects like technologies and operating practices may be taken into account.
The benchmarked entity can be a facility, an activity, a process, a product, a service or an organisation. Energy efficiency benchmarking is related to energy management, energy audits and energy efficiency calculation methods. The benchmarking methodology model for this standard is shown with the main steps in Figure 1.
Figure 1 — Benchmarking methodology model The basis of the approach can be briefly described as follows: — purpose & planning (see 4.2.1): define the objectives for the benchmarking, including definition and select the approach and type of benchmarking, produce a project plan and assign resources; — data collection & verification (see 4.2.2): agree on data collection method, collect and verify data and collate the findings to enable analysis; — analysis & results (see 4.2.3): assess current performance levels, produce tables, charts and graphs to support analysis and seek explanations for the differences in performance; — reporting (see 4.2.4): communicate results including lessons learned.

EN 16231:2012 (E) 5 The following step is optional in accordance with management systems in the organisation (see Annex F): — monitoring & actions: implement specific actions, monitor progress and implement specific actions including those from lessons learned. SIST EN 16231:2012



EN 16231:2012 (E) 6 1 Scope This European Standard specifies requirements and provides recommendations for energy efficiency benchmarking methodology. The purpose of energy efficiency benchmarking is to establish the relevant data and indicators on energy consumption, both technical and behavioural, qualitative and quantitative in comparing performance between or within entities. Energy efficiency benchmarking can be either internal (within a specific organisation) or external (between organisations including competitors). This standard describes how to establish the boundaries of what is being benchmarked, including for example facilities, activities, processes, products, services and organisations. This European Standard provides guidance on the criteria to be used in order to choose the appropriate level of detail for the data collection, processing and reviewing which suits the objective of the benchmarking.
This European Standard does not itself state specific performance requirements with respect to energy use. For all activities related to the continual improvement cycle (such as the Plan-Do-Check-Act methodology) reference shall be made to management systems in the organisation. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. No normative references are cited. 3 Terms and definitions For the purposes of this European Standard the following terms and definitions apply.
3.1 benchmark reference or standard value for comparison derived from benchmarking 3.2 benchmarking process of collecting, analysing and relating performance data of comparable activities with the purpose of evaluating and comparing performance between or within entities
Note 1 to entry: Different types of benchmarking exist, ranging from internal benchmarking to establishing the "best in industry/sector" performance. Internal benchmarking is looking for differences in energy efficiency within an organisation and highlighting best practices for dissemination to other parts of that organisation. External benchmarking may be used to establish a range of energy performance indicators for an installation/facility or a specific product/service in the same field or sector.
3.3 benchmarking boundary limit to the process installation, facility, product, building or organisation being benchmarked
Note 1 to entry: The boundary may relate to a single process installation or facility, a finished product, a single building (including all the products or processes carried on inside that building), a division or operational unit of an organisation, or an entire organisation or group of organisations. Note 2 to entry: The energy efficiency of an installation/facility or a specific product depends on the boundary of the process that is being benchmarked and how all energy flows, feedstock(s)/raw material(s) and (by)product(s) crossing the boundary of the process installation are to be taken into account.

Note 1 to entry: Although technically incorrect, energy consumption is a widely used term. Note 2 to entry: The manner or kind of application of energy is expressed as energy use. 3.8 energy efficiency ratio or other quantitative relationship between an output of performance, service, goods or energy, and an input of energy EXAMPLE Conversion efficiency; energy required/energy used; output/input; theoretical energy used to operate/energy used to operate. Note 1 to entry: Both input and output need to be clearly specified in quantity and quality, and be measurable. Note 2 to entry: Energy efficiency is commonly used with the meaning of "optimum energy efficiency" namely "to operate (an entity) with the minimum energy consumption".
Note 3 to entry: Commonly used sense of energy efficiency is doing at least the same with less energy. Note 4 to entry: In energy efficiency benchmarking, energy efficiency is usually based on the specific energy consumption of the manufacture or supply of the product, activity or service being benchmarked and is expressed for example as GJ/tonne or GJ/standard activity. 3.9

EN 16231:2012 (E) 9 4 Energy efficiency benchmarking methodology 4.1 Minimum requirements for energy efficiency benchmarking The energy efficiency benchmarking process shall, as a minimum, include the following: — definition of deliverables for each step; — definition of the energy efficiency benchmarking objective(s) and the entitie(s) and boundarie(s); — definition of the target group of the benchmarking; — definition of the characteristics for selecting the sample; — selection of participants and designation of the coordinator and establishing their roles; — definition of conditions for accurate, reliable and comparable data collection; — definition of level of confidentiality of collected data and of database ownership and access conditions; — verification of collected data; — validation of the benchmarking results by coordinator and participants; — definition of reporting content, depending on objective and participants. 4.2 Benchmarking steps 4.2.1 Purpose and planning Energy efficiency benchmarking starts with the definition of specific objectives of that benchmarking.
The type of benchmarking (i.e. internal or external) shall be selected depending on: — the need that has motivated the benchmarking; — whether a particular benchmark shall be derived.
EXAMPLE 1 Example of need triggering and leading to internal benchmarking: comparison of energy performance on different locations within the same organisation in order to improve energy performance. EXAMPLE 2 Example of need triggering and leading to external benchmarking: better understanding of the statistical energy performance (average, minimum, maximum, scattering, etc.) of a sector. Management commitment for carrying out the benchmarking is important. Approval for resources shall be obtained. The coverage of the energy efficiency benchmarking (i.e. geographical, sector specific and/or technical) shall be defined. The participants and their main characteristics shall be determined in relation to the product(s), service(s) and associated technologies which are subject of the benchmarking. The data collection method shall be determined depending on the objectives, participants and allocated resources.
Annex A provides an example of a checklist for an energy efficiency benchmarking. A coordinator shall be nominated and their role shall be established. In case of external benchmarking, participants shall approve the nominated coordinator, in order to ensure confidentiality of collected data and information. The coordinator of the energy efficiency benchmarking should SIST EN 16231:2012



EN 16231:2012 (E) 10 have appropriate knowledge in energy management. Preferably, the coordinator should have a good knowledge of the products or services and related technologies which are to be benchmarked. It shall be defined whether correction factors such as weather conditions, product or service and associated technology, production level, quality of feedstock used, will be taken into account. A documented project plan shall be developed. Participants should take part in the definition of the project plan. The project plan shall include the method for: — data collection template (e.g. questionnaire, self-declaration, walkthrough audit, energy audit/diagnosis); — data processing; — data storage (database); — data control, verification and validation. The project plan shall also include: — confidentiality requirements; — database ownership and accessibility; — result distribution criteria; — reporting rules, such as presentation formats and level of detail (e.g. units, tables and graphs). 4.2.2 Data collection and verification In order to perform energy efficiency benchmarking the coordinator (or designated investigators) shall draw up a data collection template in which the type, format and accuracy of the required input data is describ
