  • In June 2011, the International Organization for Standardization released ISO 50001, a standard for energy management systems
  • The standard aims to help organizations establish the systems and processes to improve their energy performance, including efficiency and consumption. The ISO says the standard is applicable to all types and sizes of organizations. 
  • It originated out of a request for an international energy management standard from the United Nations Industrial Development Organization (UNIDO). In 2008 ISO created a project committee, ISO/PC 242, Energy management, to develop the standard.

2. Acronyms/Definitions
  1. Boundaries - Physical or site limits and/or organizational limits as defined by the organization. Examples include a process, a group of processes, a plant, an entire organization or multiple sites under the control of an organization.

  2. CIP - Continuous Improvement Process - An ongoing effort to improve products, services, or processes. Recurring process which results in enhancement of energy performance and the energy management system The process of establishing objectives and finding opportunities for improvement is a continual process. Continual improvement achieves improvements in overall energy performance, consistent with the organization’s energy policy.

  3. Correction - Action to eliminate a detected nonconformity.

  4. Corrective action - A change implemented to address a weakness identified in a management system. Normally corrective actions are implemented in response to a customer complaint, abnormal levels of internal nonconformity, nonconformities identified during an internal audit or adverse or unstable trends in product and process monitoring such as would be identified by SPC.There can be more than one cause for a nonconformity. Corrective action is taken to prevent recurrence whereas preventive action is taken to prevent occurrence.

  5. Energy - For the purpose of this standard, energy refers to the various forms of energy, including renewable, which can be purchased, stored, treated, used in equipment or in a process, or recovered.

  6. Energy baseline - Quantitative reference(s) providing a basis for comparison of energy performance. An energy baseline reflects a specified period of time. An energy baseline can be normalized using variables affecting energy use and/or consumption such as production level, degree days (outdoor temperature), etc. Energy baseline is also used for calculation of energy savings, as a reference before and after implementation of energy performance improvement actions.

  7. Energy efficiency - Ratio or other quantitative relationship between an output of performance, service, goods or energy, and an input of energy. Examples are conversion efficiency, energy required/energy used, output/input, theoretical energy used to operate/energy used to operate. Both input and output have to be clearly specified in quantity and quality, and be measurable.

  8. EnMS - Energy management system - Set of interrelated or interacting elements to establish an energy policy and energy objectives, and processes and procedures to achieve those objectives.

  9. EMS - Energy Management System - A system of computer-aided tools used by operators of electric utility grids to monitor, control, and optimize the performance of the generation and/or transmission system. The monitor and control functions are known asSCADA; the optimization packages are often referred to as "advanced applications".

    The computer technology is also referred to as SCADA/EMS or EMS/SCADA. In these respects, the terminology EMS then excludes the monitoring and control functions, but more specifically refers to the collective suite of power network applications and to the generation control and scheduling applications.

  10. Energy management team - Person(s) responsible for effective implementation of the energy management system activities and for delivering energy performance improvements. The size and nature of the organization, and available resources, will determine the size of the team. The team may be one person, such as the management representative.

  11. Energy objective - Specified outcome or achievement set to meet the organization's energy policy related to improved energy performance

  12. Energy performance - measurable results related to energy efficiency, use and consumption. In the context of energy management systems, results can be measured against the organization’s energy policy, objectives, targets and other energy performance requirements. Energy performance is one component of the performance of the energy management system.

  13. EnPI - Energy performance indicator - Quantitative value or measure of energy performance as defined by the organization. EnPIs could be expressed as a simple metric, ratio or a more complex model.

  14. Energy policy - Statement by the organization of its overall intentions and direction of an organization related to its energy performance as formally expressed by top management. The energy policy provides a framework for action and for the setting of energy objectives and energy targets.

  15. Energy review - Determination of the organization’s energy performance based on data and other information leading to identification of opportunities for improvement. In other regional or national standards, concepts such as identification and review of energy aspects or energy profile are included in the concept of energy review.

  16. Energy target - Detailed and quantifiable energy performance requirement, applicable to the organization or parts thereof, that arises from the energy objective and that needs to be set and met in order to achieve this objective.

  17. Internal audit - Systematic, independent and documented process for obtaining evidence and evaluating it objectively to determine the extent to which requirements are fulfilled.

  18. ISO - International Organization for Standardization - Geneva, Switzerland, an international standard-setting body composed of representatives from various national standards organizations. Founded in 1947, the organization promulgates worldwide proprietary, industrial and commercial standards.

  19. ISO 9000 - Quality management standards - Designed to help organizations ensure they meet the needs of customers and other stakeholders. Third party certification bodies provide independent confirmation that organizations meet the requirements of ISO 9001. Over a million organizations worldwide are independently certified, making ISO 9001 one of the most widely used management tools in the world today. Similar to ISO 50001 in that both pertain to the process of how a product is produced, rather than to the product itself.

  20. ISO 14000 - Environmental management standards - Exist to help organizations (a) minimize how their operations (processes etc.) negatively affect the environment (i.e. cause adverse changes to air, water, or land); (b) comply with applicable laws, regulations, and other environmentally oriented requirements, and (c) continually improve in the above. The ISO 14000 family includes most notably the ISO 14001 standard, which represents the core set of standards used by organizations for designing and implementing an effective environmental management system. Other standards included in this series are ISO 14004, which gives additional guidelines for a good environmental management system, and more specialized standards dealing with specific aspects of environmental management. Similar to ISO 50001 in that both pertain to the process of how a product is produced, rather than to the product itself.

  21. Nonconformity - Non-fulfilment of a requirement

  22. Organization - Company, corporation, firm, enterprise, authority or institution, or part or combination thereof, whether incorporated or not, public or private, that has its own functions and administration and that has the authority to control its energy use and consumption. An organization can be a person or group of people.

  23. Preventive action - Action to eliminate the cause of a potential nonconformity. There can be more than one cause for a potential nonconformity. Preventive action is taken to prevent occurrence whereas corrective action is taken to prevent recurrence.

  24. Procedure - Specified way to carry out an activity or a process Procedures can be documented or not. When a procedure is documented, the term “written procedure” or “documented procedure" is frequently used.

  25. Record - Document stating results achieved or providing evidence of activities performed Records can be used, for example, to document traceability and to provide evidence of verification, preventive action and corrective action.

  26. Scope - Extent of activities, facilities and decisions which the organization addresses through an EnMS, which can include several boundaries The scope can include the energy related to transport.

  27. SDO - Standard Development Organization - Any organization whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise producing technical standards that are intended to address the needs of some relatively wide base of affected adopters.

    Most standards are voluntary in the sense that they are offered for adoption by people or industry without being mandated in law. Some standards become mandatory when they are adopted by regulators as legal requirements in particular domains.

  28. Significant energy use - Energy use accounting for substantial energy consumption and/or offering considerable potential for energy performance improvement Significance criteria are determined by the organization.

  29. Top management - Person or group of people who directs and controls an organization at the highest level. Top management controls the organization defined within the scope and boundaries of the energy management system.

3. Business Case
  • ISO 50001 is designed to help companies make better use of their energy-consuming assets, evaluate and prioritize the implementation of energy-efficient technology, and promote efficiency throughout the supply chain. It is designed to integrate with other management standards, especially ISO 14001 on environmental management and ISO 9001 on quality management.

  • ISO 50001:2011 Abstract
    • Specifies requirements for establishing, implementing, maintaining and improving an energy management system, whose purpose is to enable an organization to follow a systematic approach in achieving continual improvement of energy performance, including energy efficiency, energy use and consumption.

                          5. Risks/Issues
                          • Coordination with Existing Standards - Several countries already have national energy management standards (Spain, Denmark, Ireland, Sweden, US, Thailand, Korea) ;The EU has completed work on a regional energy management standard, EN 16001;
                            Energy management standards are under development in Brazil
                          • Certification - Whether or not to certify the Energy Management System by an external organization

                          6. Success Factors
                          1. Executive Leadership - ISO 50001 stresses the involvement of executive leadership, saying that top management must establish, implement and maintain an energy policy. They must identify the scope of the system, communicate its importance, ensure that appropriate targets and performance indicators are established and ensure that results are measured.
                          2. Build on Successes with other Process Standards - Experience gained with implementing ISO9000 and ISO14000 family standards provides a foundation to develop and implement EnMS standards

                          7. Case Studies
                          • Schneider Electric’s head office (known as the Hive1) was one of the first to be  certified as complying with the new ISO 50001 standard for energy management systems 
                          • There are 24 companies working in the pilot mode of ISO 50001, across all types of manufacturing sectors and at all sizes.
                          • Between 2008 and 2010, five initial facilities in Texas were piloted, and have been certified to date. The nergy improvements achieved at the facilities ranged from 6.5 percent to 17.1 percent over a three-year period.

                            Among the initial feedback from the pilot project include the benefits of having a cross-functional plant energy management team that goes beyond just operations or engineering means that energy management becomes a shared responsibility, and that makes it much easier to incorporate significant changes in energy use.

                            One of the biggest shifts that the pilot projects found was that as a result of going through ISO 50001 certification, energy management became a way of doing business, instead of a project-by-project undertaking.
