6、2 ISO 50002:2014(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a s
7、ubject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
8、(IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should
9、be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for ident
10、ifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the conveni
11、ence of users and does not constitute an endorsement.

12、 Supplementary information The committee responsible for this document is Technical Committee ISO/TC 242, Energy management.iv ISO 2014 All rights reserved ISO 50002:2014(E) Introduction The purpose of this International Standard is to define the minimum set of requirements leading to the identifica
13、tion of opportunities for the improvement of energy performance. An energy audit comprises a detailed analysis of the energy performance of an organization, equipment, system(s) or process(es). It is based on appropriate measurement and observation of energy use, energy efficiency and consumption. E
14、nergy audits are planned and conducted as part of the identification and prioritization of opportunities to improve energy performance, reduce energy waste and obtain related environmental benefits. Audit outputs include information on current use and performance and they provide ranked recommendati
15、ons for improvement in terms of energy performance and financial benefits. An energy audit can support an energy review and can facilitate monitoring, measurement and analysis as described in ISO 50001, or it can be used independently. This International Standard allows for differences in approach a
16、nd in terms of scope, boundary and audit objective and seeks to harmonize common aspects of energy auditing in order to enhance clarity and transparency. The energy audit process is presented as a simple chronological sequence, but this does not preclude repeated iterations of certain steps. The mai
17、n body of this International Standard covers the general requirements and framework common to all energy audits that can be supplemented by equivalent national audit standards. For auditing of specific types of facilities, processes or equipment, refer to the relevant international, national and loc
18、al standards and guidelines, some of which are referenced in the Bibliography. In this International Standard, the following verbal forms are used: “shall” indicates a requirement; “should” indicates a recommendation; “may” indicates a permission; “can” indicates a possibility or a capacity. ISO 201
19、4 All rights reserved v Energy audits Requirements with guidance for use 1 Scope This International Standard specifies the process requirements for carrying out an energy audit in relation to energy performance. It is applicable to all types of establishments and organizations, and all forms of ener
20、gy and energy use. This International Standard specifies the principles of carrying out energy audits, requirements for the common processes during energy audits, and deliverables for energy audits. This International Standard does not address the requirements for selection and evaluation of the com
21、petence of bodies providing energy audit services, and it does not cover the auditing of an organizations energy management system, as these are described in ISO 50003. This International Standard also provides informative guidance on its use (see Annex A). 2 Normative references There are no normat

These principles help to make the energy audit
38、an effective and reliable tool in support of management decisions and controls, by providing information on which an organization can act in order to improve its energy performance. Adherence to these principles provides a consistent approach to an effective energy audit that would enable energy aud
39、itors, working independently from one another, to reach similar conclusions in similar circumstances. It is essential that energy auditor(s) are familiar with applicable health and safety requirements throughout the audit process. The organization selects the energy auditor(s) based on the expected
40、energy audit scope, boundaries, audit objectives and their competencies. 4.2 Energy auditor 4.2.1 Competency Application of the following principles by the energy auditor is fundamental to the success of the energy audit. The energy auditor shall have the knowledge and skills necessary to complete t
41、he defined energy audit scope. Competence can be shown by: a) appropriate education, skills, experience and/or training considering local or national guidelines and recommendations; b) relevant technical skills specific to the energy uses, scope, boundaries and audit objective; ISO 2014 All rights r
42、eserved 3 ISO 50002:2014(E) c) knowledge of appropriate legal and other requirements; d) familiarity with the energy uses being audited; e) knowledge of the requirements of this International Standard, national and local energy auditing standards; f) (for a team member designated as lead energy audi
43、tor) having the skills to manage and provide leadership to the energy audit team: a lead auditor should have managerial, professional and leadership skills in order to manage a team. NOTE 1 Where there is a single auditor, he/she is considered to be the lead auditor. NOTE 2 Where a national or local
44、 energy auditor certification scheme, or equivalent, is available, certified energy auditors can be considered. Some schemes can be technology specific. NOTE 3 The energy auditor is encouraged to demonstrate continual professional development to maintain and improve auditing knowledge, technical ski
45、lls and personal attributes. Continual professional development could be achieved through means such as attendance at meetings, seminars, conferences, technical training, work experience, self- study, coaching, or other relevant activities. 4.2.2 C onfidentiality The confidentiality of the audit del
46、iverables shall be agreed upon by the organization and the auditor prior to the start of the energy audit. Energy audit information shall not be used inappropriately for personal gain by the energy auditor, or in a manner detrimental to the legitimate interest of the organization. NOTE This concept
47、includes the proper handling of sensitive or confidential information. 4.2.3 Objectivity The energy auditor shall act independently and in an impartial manner. Conflicts of interest (personal, financial or other) shall be identified and disclosed to the organization in a timely manner. If the organi
48、zation intends to carry out an energy audit using internal personnel, every effort should be made to remove bias and encourage objectivity. 4.2.4 Access to equipment, resources and information For completion of the energy audit based on the defined energy audit scope and boundaries, access is requir
49、ed to: a) the organization, facility/facilities, equipment, system(s) and process(es); b) personnel (engineering, operations, maintenance, etc.), their equipment vendors, contractors and others to collect information pertinent and useful to the energy audit and analysis of data; c) other information sources, such as drawings, manuals, test reports, historical utility bill information, monitoring and control data, electrical equipment panels and calibration records. 4.3 Energy audit The energy audit shall be conducted according
