DIN EN 16247-3:2014-08 EN 16247-3:2014 (E) 4 0 Introduction An energy audit can help an organization to identify opportunities to improve energy efficiency. It can be part of a site wide energy management system. There are various sectors with imp
20、ortant differences in processes and utilities. It should be emphasized that there are many types of processes in industry and commerce. In general, energy is used: directly by a process, e.g. furnaces, direct fired dryers, etc; indirectly by a process (e.g. heat exchange, distillation, extrusion, et
21、c.) including the specific conditions of production (e.g. start-up, shut-down, product change over, cleaning, maintenance, laboratory and product transfer); utility processes (e.g. motor driven systems (fans, pumps, motors, compressors, etc.), steam, hot water), including on site power plants; other
22、 processes (e.g. sterilization in hospitals, fume cupboards, laboratories etc.). This standard defines the attributes of a good quality energy audit on a site in addition to EN 16247-1, which gives the general requirements for energy audits. DIN EN 16247-3:2014-08 EN 16247-3:2014 (E) 5 1 Scope This
23、European standard specifies the requirements, methodology and deliverables of an energy audit within a process. These consist of: a) organizing and conducting an energy audit; b) analysing the data from the energy audit; c) reporting and documenting the energy audit findings. This part of the standa
24、rd applies to sites where the energy use is due to process. It shall be used in conjunction with and is supplementary to EN 16247-1, Energy audits Part 1: General requirements. It provides additional requirements to EN 16247-1 and shall be applied simultaneously. A process could include one or more
25、production lines, offices, laboratories, research centers, packaging and warehouse sections with specific operational conditions and site transportation. An energy audit could include the whole site or part of a site. If buildings are included in the scope of the energy audit, the energy auditor may
26、 choose to apply EN 16247-2, Energy Audits Part 2: Buildings. If on-site transport on a site is included in the scope of the energy audit, the energy auditor may choose to apply EN 16247-4, Energy audits Part 4: Transport. NOTE The decision to apply Parts 2 and 4 could be made during the preliminary
27、 contact, see 5.1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1624

31、try: This may include pollution treatment processes and energy recovery, and waste product. 3.5 building construction as a whole, including its envelope and all technical building systems, for which energy may be used to condition the indoor climate, to provide domestic hot water and illumination an
32、d other services related to the use of the building and the activities performed within the building Note 1 to entry: The term can refer to the building as a whole or to parts thereof that have been designed or altered to be used separately. Note 2 to entry: The building could include its site locat
33、ion and related external environment. SOURCE: EN 16247-2, 3.1 3.6 energy electricity, fuels, steam, heat, compressed air, and other like media Note 1 to entry: For the purposes of this standard, energy refers to the various forms of energy, including renewable, which can be purchased, stored, treate
34、d, used in equipment or in a process, or recovered. Note 2 to entry: Energy can be defined as the capacity of a system to produce external activity or perform work. SOURCE: EN ISO 50001, 2011, 3.5 4 Quality requirements 4.1 Energy auditor The qualification of an energy auditor is defined in prEN 162
35、47-51. 1prEN 16247-5 is currently not yet published and under development. DIN EN 16247-3:2014-08 EN 16247-3:2014 (E) 7 4.2 Energy audit process The quality of the energy audit depends on the knowledge of the processes, the site and available data and information. Close collaboration between the ene
36、rgy auditor and the organization is essential. NOTE An example energy audit process is shown in Annex A. 5 Elements of the energy audit process 5.1 Preliminary contact The energy auditor shall obtain a preliminary description of the site and the process from the organization or from a site visit. NO
37、TE The preliminary contact can be by telephone, webinar, meeting or other remote interactive discussions. The energy auditor shall agree with the organization on the scope and boundary of the energy audit: a) processes included in the energy audit; NOTE A process can be defined as the whole process,
38、 part of a process, part of a system or a component. b) whether or not outsourced utilities are included in the energy audit; c) depending of the thoroughness of the energy audit, it is recommended to check if a detailed energy audit needs to be carried out for specific processes. In this case, refe
39、rence shall be made to the relevant standard (see bibliography). For energy use not directly related to process (e.g. storing, packaging, logistics, offices, research centre, laboratory and transport), the energy auditor shall agree with the organization the applicability of EN 16247-2 and EN 16247-
40、4. This choice and the agreed scope shall be clearly stated in the final energy audit report (5.6). For each audited process, the energy auditor and organization shall agree, the relevant personnel, their roles which have an impact on energy consumption, and propose a preliminary list of data to be
41、collected. 5.2 Start-up meeting The energy auditor and organization shall agree energy performance indicators which can be used in the energy audit. 5.3 Collecting data 5.3.1 General The data collection could be carried out over several stages during an energy audit. During data collection, the ener
42、gy auditor shall: a) verify the data and information provided by the organization (e.g. the power or the number of pieces of equipment); DIN EN 16247-3:2014-08 EN 16247-3:2014 (E) 8 b) obtain any missing data; c) check the accuracy of the measuring device. 5.3.2 Information request The energy audito
43、r shall request from the organization the following: a) site information; b) utility processes information; c) production processes information; 1) product specification and quality; 2) current operational conditions (set points) of utilities and production process; 3) specific condition and constra
44、int for process and environment (security, pollution, health, etc.); d) building, boundary and other relevant information; e) energy sources information. NOTE 1 The collected data can be based on invoices, contracts, measurements, calculations from given operating hours and installed capacity (techn
45、ical characteristics), operation and maintenance documents, meeting with operations and maintenance personnel, etc. NOTE 2 See Annex B for examples of data to be collected. 5.3.3 Review of the available data The energy auditor shall review the information collected for consistency and suitability. T
46、he energy auditor shall assess whether the information provided is sufficient to achieve the agreed objective. If data requested is not available, the energy auditor shall define the method to obtain the necessary information (e.g. measurements, estimates, modelling, etc.). 5.3.4 Preliminary data an
47、alysis The energy auditor shall carry out an analysis of the data collected to: a) undertake a preliminary analysis of the sites energy balance on the basis of energy bills and output; b) establish the relevant adjustment factors; c) establish the relevant energy performance indicator; d) evaluate t
48、he distribution of energy consumption on the basis of sub-meter reading, installed capacity and operating time; e) if there is sufficient information, establish an initial energy baseline; DIN EN 16247-3:2014-08 EN 16247-3:2014 (E) 9 f) plan further data collection and measurement to be carried out
49、during field works (5.4). The energy auditor should develop preliminary energy efficiency improvement opportunities. The energy auditor shall agree with the organization about any data measurement plan on: 1) objectives and parameters; 2) content; 3) required measurement conditions. NOTE See Annex C for quality data measurement plans. 5.4 Field work 5.4.1 Aim of field work If necessary, the energy auditor shall carry out additional measurement to: a) collect any missing data needed for analysis; b) confirm the suitability of the baseline; c) co
