If a certification body conducts activities for the purpose of energy management system audit and certification in accordance with GB/T23331—2012 "Energy Management System Requirements" and hopes to obtain recognition, it is necessary to add requirements and guidelines related to energy management system audit on the basis of ISO/IEC17021:2011 "Conformity Assessment Management System Certification Body Requirements". ISO/IEC170212011 "Conformity Assessment Management System Certification Body Requirements" is an international standard that proposes operating guidelines for organizations that implement management system certification. It stipulates the basic principles and requirements that management system certification bodies should follow in their operations.
This standard adds requirements and guidelines related to energy management system audits based on ISO/IEC17021:2011 "Requirements for Certification Bodies for Conformity Assessment Management Systems". It particularly stipulates specific requirements for energy management system certification and audits, such as the knowledge and skills that certification personnel should have, the management of certification-specific information, specific factors to be considered in audit planning, and the main contents of audit implementation and reporting, so that certification bodies have the ability to certify energy management systems and implement certification in a consistent and fair manner based on the actual activities and characteristics of customer energy management, thereby promoting stakeholders to recognize certification bodies and their energy management system certification results. Appendix A explains the expected results of energy management system certification from the perspective of stakeholders
Based on the requirements of 10/IEC17021:2011, and clarifies the specific requirements of energy management systems in this standard
based on the characteristics of energy management system certification.
This standard introduces the concept of "energy management system technical field", breaks through the division of the business scope of the traditional management system, highlights the characteristics of the energy management system that focuses on data and energy technology applications, and proposes the division principles of the energy management system technical field in view of the energy consumption and energy management characteristics of various economic activities. In view of the professional characteristics of energy management, it clearly stipulates the competence criteria of energy management system auditors from three aspects, and adds more professional requirements of energy management in the first part. This standard focuses on the application of relevant laws and regulations and standards for energy source management, highlights the ten quantities of energy management, energy market planning, energy network diagram, energy balance sheet, energy professional specialties such as energy planning, and clearly expresses the quantitative results of energy performance and verification methods in the certification documents (certification certificates) that express the certification results of the energy management system. In addition, this standard mainly seeks to be more in line with the objective laws of the audit process and more reasonable in determining the audit time. For example, in the relevant provisions of Appendix E audit time, the degree of complexity of energy factors in the field of energy management technology in the industry is mainly considered, and the method of calculating audit man-days for energy management is considered; in the case of multi-site certification of energy management systems, the complexity of the system is weakened, and the audit time for each site is calculated separately, considering the difference between the management activities of the sub-sites and the activities of a single site or a central functional organization. 1 Scope
Conformity Assessment Requirements for Energy Management System Certification Bodies GB/T27309—2014

Note: Carrying out activities in a similar manner means that the sites operate under the same energy management system, have similar energy use and energy consumption, the same type of production capacity, energy-using processes and equipment and facilities, and the main factors affecting energy performance such as site size, process, raw materials, product types, measurement methods, energy laws and regulations, and similar energy management levels. And each site is included in the client's energy management system internal audit plan and management review plan. 9.1.5.2 When the certification body conducts sampling audits on multiple sites of the client organization, it should have procedures: determine the appropriate sampling level and representative sites according to the specific conditions of the energy consumption systems in different sites, and indicate the rationality of the sampling a)
;
, on the premise that their products/services and energy-consuming equipment, facilities, and systems are roughly the same or similar, the sampling should also take into account the differences in energy data collection and aggregation modes, energy types, and energy consumption of the sub-sites; to ensure the rationality of such sampling, the certification body should identify the differences between sites to the greatest extent possible during the initial certification application review to determine the appropriate sampling method and level; d) In a certification cycle, the surveillance audit should cover all sites. 7
