18、rkey and the United Kingdom. BS EN 16247-3:2014EN 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 important differences in process
19、es 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, etc.) including the specific co
20、nditions 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 processes (e.g. sterilizatio
21、n 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. BS EN 16247-3:2014EN 16247-3:2014 (E) 5 1 Scope This European standard specifies the re
22、quirements, 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 standard applies to sites where the ener
23、gy 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 production lines, offices, laborat
24、ories, 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 choose to apply EN 16247-2, Energ
25、y 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 contact, see 5.1. 2 Normative ref
26、erences 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 16247-1, Energy audits - Part 1: Gener

34、et published and under development. BS EN 16247-3:2014EN 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 energy auditor and the organization is essentia
35、l. 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. NOTE The preliminary contact can be by telepho
36、ne, 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, part of a process, part of a system or a co
37、mponent. 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, reference shall be made to the relevant standard
38、 (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 16247-4. This choice and the agreed scope shall be
39、 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 collected. 5.2 Start-up meeting The energy a
40、uditor 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 energy auditor shall: a) verify the data and inf
41、ormation provided by the organization (e.g. the power or the number of pieces of equipment); BS EN 16247-3:2014EN 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 auditor shall request from the organization the followi
42、ng: 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 constraint for process and environment (security, pollut
43、ion, 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 (technical characteristics), operation and maintenance
44、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. The energy auditor shall assess whether the inform
45、ation 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 analysis The energy auditor shall carry out an anal
46、ysis 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 the distribution of energy consumption on the basi
47、s of sub-meter reading, installed capacity and operating time; e) if there is sufficient information, establish an initial energy baseline; BS EN 16247-3:2014EN 16247-3:2014 (E) 9 f) plan further data collection and measurement to be carried out during field works (5.4). The energy auditor should de
48、velop 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.
