18、 and the United Kingdom. DIN EN 16231:2012-11 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
19、. 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 sp
20、ecific 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
21、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 servic
22、e 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 appro
23、ach can be briefly described as follows: purpose data collection analysis reporting (see 4.2.4): communicate results including lessons learned. DIN EN 16231:2012-11 EN 16231:2012 (E) 5 The following step is optional in accordance with management systems in the organisation (see Annex F): monitoring
24、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 energ
25、y 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 cons
26、umption 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 energy performance measurable results related to energy efficiency, energy use and energy consumption SOURCE: EN ISO 50001:2011 Note 1 to e
27、ntry: In the context of energy management systems, results can be measured against the organisations energy policy, objectives and targets. 3.10 entity object of benchmarking EXAMPLE Process installations, products, services, retail shops, buildings.

34、(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
35、) 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 compar
36、able 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 particip
37、ants. 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
38、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
39、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.
40、 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
41、 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
42、 order to ensure confidentiality of collected data and information. The coordinator of the energy efficiency benchmarking should DIN EN 16231:2012-11 EN 16231:2012 (E) 10 have appropriate knowledge in energy management. Preferably, the coordinator should have a good knowledge of the products or serv
43、ices 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. P
44、articipants 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 vali
45、dation. 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
46、 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 described in a clear and unambiguous way. To make sure that the questionnaire ensuing from this template is adeq
47、uate and complete, its content could be presented to the benchmarking participants in order to ensure consensus. The coordinator shall further take care of following actions: compile a request for information and data on energy performance to the target group participants using the agreed template;
48、review and control the use of and agreement on correction factor(s); perform a first plausibility check of the received input data. (Annex D provides examples of tools to perform this check); in case of external benchmarking the processed data shall be made anonymous by decoupling them from the identification of the participant; calculate the energy efficiency based on the received input data points and rank these output data according
