  5. 5. ISO/CD 50001ForewordISO (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 ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with theInternational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patentrights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 50001 was prepared by Project Committee ISO/PC 242, Energy management.© ISO 2009 – All rights reserved v
  6. 6. ISO/CD 50001IntroductionThe purpose of this International Standard is to enable organizations to establish the systems and processesnecessary to improve energy performance, including energy efficiency and intensity. The standard shouldlead to reductions in cost, greenhouse gas emissions and other environmental impacts, through systematicmanagement of energy. It is applicable to all types and sizes of organizations irrespective of any geographical,cultural or social conditions. Successful implementation depends on commitment from all levels and functionsof the organization, and especially from top management.This International Standard specifies requirements for an energy management system (EnMS) to develop andimplement an energy policy, establish objectives, targets, and action plans, which take into account legalrequirements and information pertaining to significant energy use. An energy management system enablesan organization to achieve its policy commitments, take action as needed to improve its energy performanceand demonstrate the conformity of the system to the requirements of this International Standard. Applicationof the standard can be tailored to fit the requirements of the organization, including complexity of the system,degree of documentation, and resources and applies to the activities under the control of an organization.This International Standard is based on the Plan-Do-Check-Act continual improvement framework andincorporates energy management into everyday organization practices. The basis of this approach is shownin Figure 1. Figure 1 — Energy Management System ModelGlobal application of this standard will contribute to greater energy supply availability, enhancedcompetitiveness, and a positive impact on climate change. This standard considers all types of energy.Note 1 energy supply availability otherwise known as security of energyvi © ISO 2009 – All rights reserved
  7. 7. ISO/CD 50001Note 2 energy includes renewable, non-renewable, recovered, etc.This International Standard can be used for certification/registration and/or self-declaration of anorganizations energy management system. It does not establish absolute requirements for energyperformance beyond the commitments in the energy policy of the organization and its obligation to complywith relevant legislation. Thus, two organizations carrying out similar operations but having different energyperformance can both conform to its requirements.The organization may choose to integrate ISO 50001 with those of other management systems such asquality, environment, occupational health and safety or social responsibility.© ISO 2009 – All rights reserved vii
  8. 8. COMMITTEE DRAFT ISO/CD 50001Energy management systems — Requirements with guidancefor use1 ScopeThis International Standard specifies requirements for an organization to establish, implement, maintain, andimprove an energy management system, which enables an organization to take a systematic approach inorder to achieve continual improvement of energy performance, energy efficiency, and energy conservation.An energy management system addresses: energy supply; measurement, documentation, and reporting ofenergy use; and procurement and design practices for energy-using equipment, systems, and processes. Itdoes not itself state specific performance criteria with respect to energy. The standard applies to all factorsaffecting energy use that can be monitored and influenced by the organization. This standard for energymanagement systems has been designed to be used independently but can be aligned or integrated withother management systems. This standard applies to all organizations.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

  20. 20. ISO/CD 50001 Annex A (informative) Guidance on the use of this International StandardA.1 General requirementsThe additional text given in this annex is strictly informative and is intended to prevent misinterpretation of therequirements contained in Clause 4 of this International Standard. While this information addresses and isconsistent with the requirements of Clause 4, it is not intended to add to, subtract from, or in any way modifythese requirements.The implementation of an energy management system specified by this International Standard is intended toresult in improved energy performance. Therefore this lnternational Standard is based on the premise that theorganization will periodically review and evaluate its energy management system to identify opportunities forimprovement and their implementation. The rate, extent and timescale of this continual improvement processare determined by the organization in the light of economic and other circumstances. Improvements in itsenergy management system are intended to result in further improvements in energy performance.This standard requires the organization to:a) establish an appropriate energy policy;b) identify the significant energy uses arising from the organizations activities;c) identify applicable legal requirements and other requirements to which the organization subscribes;d) identify priorities and set appropriate energy objectives and targets;e) establish a relevant structure and programme(s) to implement the policy and achieve objectives and meettargets;f) facilitate planning, control, monitoring, preventive and corrective actions, auditing and review activities toensure both that the policy is complied with and that the energy management system remains appropriate.The organization should identify and select the energy-related areas which should be managed by theorganization. That identification and selection should conform with the purpose of this management system.Also the organization should identify and select the appropriate management methods of the identified andselected energy-related areas and activities which should be conform with the purpose of this managementsystem.As shown in the below figure, energy performance is a broad term which includes energy efficiency, energyintensity, energy consumption specific energy use and so on. Energy efficiency is a basic concept of energyperformance.© ISO 2009 – All rights reserved 13
  21. 21. ISO/CD 50001 Figure A.1 — Concept of energy performanceA.2 Management responsibilityTop management sets the direction for an organization by defining objectives, targets and setting the vision.In order for an organization to successfully implement a management system, it is imperative that persons atthe highest level be committed to and responsible for it. Depending on the nature of how the organization isstructured; a range of individuals could qualify as top management. Top management should be someoneresponsible for making decisions about the organization’s future direction and vision and with the authority toset organizational priorities.Top management should ensure appropriate resources necessary for the management system are provided.It is important that the key energy management system roles, responsibilities, authorities and accountabilitiesare well defined and communicated to all persons working for or on behalf of the organization. As themanagement system develops over time, energy data should be provided to more levels within theorganization. This development over time allows the energy management system to be effectively managedat the operator level through the energy performance indicators.A.2.1 GeneralTop management may appoint an energy management representative from a higher management level,including top management to direct energy management activities from the viewpoint of management. Topmanagement’s commitment to the management system for energy and its continual improvement shoulddemonstrate:a) Direct involvement and guidance in establishing the organization’s energy policy and ensuring consistencyand synergy with other relevant organizational policies.b) The provision of adequate resources to implement and operate the management system for energy.Resources include human resources, technical skills and technology, specialized skills, planning, financialresources and outsourced energy services.c) The appointment of a management representative for the energy management system with adequateexpertise, skills, training and authority to implement the EnMSd) The identification of the scope and boundaries of the EnMS.e) Providing sufficient guidance and supervision to ensure that the EnMS is successfully put in practice,through objectives and targets and related action plans, definition of operating and control methods, periodicverification and review of performance; and that energy management is understood by all persons working foror on behalf of the organization.Inclusion of energy management in an organization’s strategic or long term planning process is also anindicator of top management’s commitment. While it is acknowledged that not all organizations have existing14 © ISO 2009 – All rights reserved
  22. 22. ISO/CD 50001capacity to undertake strategic or long term planning, organizations with or aiming at introducing a strategic orlong term planning process should consider including energy management. Information should flow in bothdirections between strategic planning and energy management. Energy management planning shouldembrace the organization’s strategic objectives and, likewise, the results of energy management planningshould be important inputs to the strategic plan. Financial information, legal considerations, design guidelines,energy resources, and technology choices can reinforce the connection between these two areas. Similarly,during management review, energy management and energy performance can be compared to theorganization’s strategic plan.Depending on the size, complexity and normal business practice of the organization, the scope andboundaries of the EnMS, the management representative might be given the responsibility to form an EnMSteam.The energy management system team could include, as appropriate, representatives from functional areasdealing with the selection, procurement, consumption, reliability, disposal and environmental impacts of fuels,and energy systems. Representative areas may include but are not limited to: purchasing, accounting,engineering, design, production, maintenance, facilities management, environmental, and external serviceproviders, as appropriate. EnergyThe energy management system team should:identify the facilities, equipment, processes and personnel working for or on behalf of the organization thatsignificantly affect energy consumption and demand, significant energy uses and cost;identify other relevant variables affecting energy consumption;establish energy performance indicators;record the method(s) for identifying these significant energy uses;review the identified significant energy uses on a regular basis;modify the list of significant energy uses as operational and facility changes occur; andidentify and prioritize opportunities for improving energy performance.The members of EnMS team should have:a) the skill through appropriate experience of more than one year;b) appropriate training or qualification related to energy management;c) knowledge of theories for improving energy management system; andd) a central role in promoting energy efficiency in the field.A.2.2 Roles, responsibility and authorityIt is critically important for the successful implementation of the energy management system that the key roles,responsibilities, authorities and accountabilities are well defined and communicated to all persons working foror on behalf of the organization. Roles, responsibilities and authority are typically defined throughorganizational charts, job descriptions, procedures, work instructions or training. Depending on theorganizational structure and management system scope, the energy management representative, to beappointed by the top management, may work alone or with the support of a team that represents and supportactivities of the EnMS within the organization.The term “management representative” is not always meant to represent a specific positional title, but toreflect the core activities of the position; namely, management and coordination of the EnMS across thefunctional areas of the organization and reporting to top management on system and energy performance.© ISO 2009 – All rights reserved 15
  23. 23. ISO/CD 50001A.3 Energy PolicyThe energy policy is top management’s official statement of the organization’s commitments to energymanagement. The policy contains at a minimum the four required commitments of continual improvement,availability of information, necessary resources to achieve the objectives and targets established by theorganization and to comply with the legal and other requirements that apply to the organization. The energypolicy drives the implementation, continual improvement of the organization’s energy management systemand energy performance. The policy is provided to the employees of an organization as well as to those whowork on behalf of the organization. Therefore, it should be simple, clear, and represent the organization’sintentions relating to energy management. If there are other policies in place within the organization, theenergy policy may be combined into one of them or it could be maintained as a separate policy.Where the organization operates at several locations, the policy may be limited to include the activities at onlysome of those locations. This should be explicitly stated in the energy policy. Within the parts of theorganization covered, the policy should indicate significant energy uses, processes and activities to which itapplies.An energy policy should: • commit the organization to address the products, processes and other activities which affect the significant energy uses, i.e. the areas which account for the highest energy consumption or which offer the most considerable potential for energy savings; • commit the organization to continual improvement of its energy performance. This means that the policy forms the framework for setting energy objectives and targets and regularly reviewing them; • commit the organization to adhere to applicable laws, regulations and other agreements which are relevant to or affect the energy use of the organization.The policy may include additional commitments such as alternative energy sources, reduced energy-relatedenvironmental impacts and renewable energy. The policy may be a brief statement that members of theorganization can readily understand and apply to their work activities.A.4 PlanningA.4.1 GeneralNo guidance at this timeA.4.2 Energy ProfileThe purpose of developing an energy profile of the organization is to understand the areas of significantenergy consumption, i.e. the buildings, equipment and processes which account for the greatest energy useor which offer the most potential for energy savings and the drivers for this energy consumption. The driverscan be areas such as production volumes, weather, occupancy, floor area, etc.The identification of the energy profile is critical in understanding where energy is used within the organizationand forms the basis for prioritizing the efforts to reduce energy consumption. The organization that intends toimplement an energy management system should start by establishing its current position with regard toenergy consumption by means of an initial review of its energy use. This is the fundamental cornerstone forestablishing and maintaining an energy management system that is tailored to the organizations energy use.a) Analyze energy use based on measurement and other data 1. How much energy the organization is consuming and its trends, changes, anomalies, etc.16 © ISO 2009 – All rights reserved
  24. 24. ISO/CD 50001 2. Estimate how much energy will be consumed in the coming period, typically the next financial budget period. 3. Examine where energy is currently being sourced which will typically be a local utility company and examine other potential sources including e.g. internal waste heat.b) Based on energy use analysis, identify the areas of significant energy use 1. Where the energy is being used, i.e. what are the significant consumers? 2. What is driving the energy use? This is often difficult to determine but is very important. 3. Which people have significant impact on energy use and identifies their relevant training needs.c) Identify and prioritize opportunities for improving energy performance, including use of renewable oralternative energy sources, where applicable. 1. Identify energy reduction opportunities by a variety of means, e.g. analysis of the data from (a) and (b) above, energy audits and studies, examination of EnPIs, energy housekeeping checks, etc. If no opportunities are found for significant energy users, it might be advisable to conduct a focused examination of that user. 2. Prioritize the known opportunities based on the organizations normal work and investment prioritization criteria. 3. It may be relevant to examine the technical and financial costs and benefits of renewable or alternative energy sources such as biomass, solar, wind, co-generation, etc.The organizations energy use will change on an ongoing basis due to plant changes such as new buildings orequipment, energy performance changes, changes of personnel, etc. Organizations will typically update theenergy profile on a regular basis, e.g. annually or when a significant change occurs.A.4.3 Energy BaselineMany organizations experience seasonal variations in output and environmental factors, so at least one yearof data should be used to generate the profile. The initial profile (energy baseline) serves as the starting pointagainst which future improvements are measured. Significant organizational changes that affect the validity ofthe EnPIs may be reasons to adjust (change) the baseline. These may include changes in:a) product mix;b) production levels;c) operating schedule;d) facility infrastructure;e) equipment and systems;f) new energy resources; org) legal or regulatory requirements.As an example, a major building addition to a school, hospital, manufacturing plant, or office building that isfunctionally different than the existing buildings would affect total energy consumption and impact the EnPI.Positive organizational energy performance is demonstrated by decreasing energy intensity which is reflectedin a downward trend in the EnPIs© ISO 2009 – All rights reserved 17
  25. 25. ISO/CD 50001It may be as simple as comparing the current years consumption with the previous year. In this case thebaseline will move annually. Some organizations may choose to update more frequently, e.g. by monitoringannual energy use on a monthly basis and moving the baseline monthly.The EnPIs and baseline should be generated using as long period of relevant data as possible, and whengenerated using more than one year of data the baseline may be adjusted (changed) to be replaced with thenew EnPI.Before the adjustment of baseline the improvements of EnPIs against the old baseline should be recorded,and the records the EnPIs improvement for the predetermined period (preferably about five years) should bepreserved to evaluate the trend of EnPIs.A.4.4 Energy performance indicatorsEnPIs are a quantitative index of energy performance as defined by the organization. The concept of an EnPIcan be used to compare organizational performance at different points in time. They should be selected tofacilitate monitoring of performance especially in the significant energy uses identified in energy profiling.Methods for defining EnPI will vary depending on the organization’s operations and complexity. Some may befocused on understanding data and EnPIs and another may be focused on analysis. In all cases the EnPIshould be easy to understand which will aid its usefulness for sharing information and improving motivation tomake improvements. Examples include: 1. Comparison of annual energy use with targeted use. 2. Energy consumption divided by production, which is a type of specific energy consumption may be used. 3. In some cases, normalized energy consumption can be used, where normalizing factors may be production amount, actual seasonal temperature, length of service time, and so on. Methods for normalization may vary such as linear compensation, or a theoretical calculation. This type of EnPI is useful for explaining the change of EnPI figure resulting from factors outside of the improvement actions. 4. When the organization chooses EnPIs whose variables are not being measured, a measurement plan should be developed and implemented. After a reliable time interval of measurement, the results should become part of the energy baseline. 5. Statistical tools can be utilized to measure the correlation of potential variables’ effect on the EnPI. Typical variables may include weather conditions, occupancy, raw material or energy resource quality, and others. 6. EnPIs can be made relevant for different functions and levels in the organization. For top management, EnPIs are typically translated to relate cost impacts and to support strategic goals. 7. Trends in the EnPI should demonstrate continual improvement of the energy performance of the organization. 8. Consideration of EnPI trends that show poor performance may be included in the preventive action process.In some circumstances it is useful to set sectoral benchmarking as an EnPI to assess the organizationsefforts and level of energy performance. This is useful only if sectoral benchmarking data is available.Sectoral benchmarking is effective specifically for certain sub-sectors initially in energy intensive industries,such as iron and steel, cement, and electricity suppliers. Indicators are determined to enable organizations tobenchmark the levels of energy efficiency against others within the same sub-sector. Targets can be set atthe energy efficiency level of the best performing organizations (top 10 to 20%) in each sub-sector (“Averagevalue Standard deviation”). In addition, sub-sectors, benchmarking indicators, and targets (levels to be18 © ISO 2009 – All rights reserved
  26. 26. ISO/CD 50001achieved) should be reviewed regularly and updated if applicable, taking into account technologicaldevelopment of these sub-sectors and other factors.Selection of EnPIs is related to baseline and should facilitate comparison with it.The organization should identify measurement requirements to monitor performance. These can be localinstruments such as temperature, pressure, flow, etc, or electronic control systems, energy managementdatabases, statistical tools, etc.A.4.5 Legal and other requirementsThe organization needs to identify the applicable legal requirements and other requirements to which theorganization subscribes related to its energy use.These may include: a) national and international legal requirements; b) state/provincial/departmental legal requirements; c) local governmental legal requirements.Examples of other requirements to which the organization may subscribe include, if applicable: d) emissions trading requirements; e) agreements with customers; f) non-regulatory guidelines; g) voluntary principles or codes of practice; h) voluntary energy agreements; i) requirements of trade associations; j) agreements with community groups or non-governmental organizations; k) public commitments of the organization or its parent organization; l) corporate/company requirements.The determination of how legal obligations and other requirements to which the organization subscribes applyto the organizations energy use is usually accomplished in the process of identifying such requirements. Theorganization should prepare and maintain a list of the pertinent energy legislation and other requirements,which affect the organizations activities, products or services. It may not be necessary, therefore, to have aseparate or additional procedure in order to make this determination.However, the organization should identify who has the responsibility for reviewing all legal obligations andother requirements to which the organization subscribes. The organization should describe how it: • communicates relevant information to the appropriate persons; • keeps up to date on new laws and regulations; • updates their register of applicable legislation at pre-defined intervals.© ISO 2009 – All rights reserved 19
  27. 27. ISO/CD 50001A.4.6 Objectives, targets and action plansSetting objectives and targets provides the means for transforming policy into action. The organization shouldensure that the objectives and targets are consistent with the energy policy and the energy profile and itssignificant users. Objectives and targets should be reviewed and revised periodically, e.g. in connection withthe management review or through the periodical revision of the energy action plans, etc. Setting energytargets ensures that the organization has defined success criteria so that progress towards improved energyperformance can be measured.Targets should be:a) ambitious, so as to commit the organization to continual improvement;b) realistic, so that they can be achieved within the specified time limits;c) specific and measurable.As a minimum targets should be established for each of the significant energy aspects identified by the energyprofile. Some targets may apply to equipment or facilities (e.g. a specific production line), while others mayaddress the energy consumption of departments (e.g. transport and logistics department), training or energyawareness or additional measurement and monitoring.Energy reduction targets could be expressed either as: • Absolute energy savings attributable to a given initiative or group of initiatives or • Through a performance improvement metric this is established taking all energy drivers into account.The purpose of establishing energy action plans is to ensure that the organization achieves its objectives andtargets. The action plan should detail how the organization plans to improve energy efficiency and shouldcontain a description of the tasks and resources required for their implementation. To avoid duplication ofresources, energy action plans should be incorporated into normal business operations.The organization should consider the possibilities of using the Best Available Technology (BAT) whenestablishing its energy management action plans. When establishing such action plans, the following shouldbe identified and addressed: • What are the priority activities and projects to be initiated, i.e. what actions will deliver the greatest improvements considering the available resources? • Whatis to be achieved and what is the timescale for delivery, i.e. define the core objective of the action and when it is to be achieved? • Who has the responsibility and what resources are required to implement the action plans, i.e. who has overall responsibility and authority to ensure that plans are implemented, what personnel are required and what funding is needed? • How are the energy action plans to be monitored and revised, i.e. how is progress to be monitored and management informed when the objective is achieved or not and how are improvements in energy performance to be documented? • Do action plans reflect the energy policy, objectives and targets together with legal and other obligations?In the process of selecting objectives, targets and action plans, the organization should consider:a) its financial criteria and priorities;b) alternative energy resources;20 © ISO 2009 – All rights reserved
  28. 28. ISO/CD 50001c) maintenance and infrastructure needs;d) operational requirements and constraints;e) quality and appropriateness of energy resources;f) environmental impacts;g) safety and health issues;h) available human and technical resources; andi) ability to measure improvement in energy performance;j) its energy profile including areas of significant use and drivers.The action plans should include an appropriate level of verification of savings achieved. In the case ofsignificant savings this should include: • energy use prior to implementation; • planned savings and benefits; • means of verifying savings which may range from simple estimates and calculations to the use of standard measurement and verification techniques; • actual implementation costs and where appropriate life-cycle costs; • the level of analysis should be commensurate with the scale of the improvement opportunity.Energy action plans should be documented and reviewed regularly to ensure they are up to date and relevant.A.5 Implementation and operationA.5.1 Competence, training and awarenessThis International Standard requires that:a) those persons identified by the organization whose work could affect significant energy uses are competentto perform the tasks to which they are assigned;b) training needs are identified and actions are taken to ensure the provision of training;c) all persons are aware of the organization’s energy policy, energy management system and the energyperformance that could be affected by their work.The organization should identify the awareness, knowledge, understanding and skills needed by any personwith the responsibility and authority to perform tasks on its behalf. Awareness, knowledge, understanding andcompetence can be obtained or improved through training, education and experience. Some kind of rewardsystem for self disciplined training could be used to enhance the effectiveness organization’s energymanagement system. The organization should require that contractors working on its behalf are able todemonstrate that their employees have the requisite competence and/or appropriate training. Managementshould determine the level of experience, competence and training necessary to ensure the capability ofpersonnel, especially those carrying out specialized energy management functions.© ISO 2009 – All rights reserved 21
  29. 29. ISO/CD 50001A.5.2 DocumentationA.5.2.1 Documentation requirementsThe level of detail within the system documentation should be sufficient to describe the energy managementsystem and the interaction between its processes, systems and activities. This documentation should bebetter to integrate with existing management systems implemented by the organization.The extent of energy management system documentation may differ from one organization and another,depending on:a) the size and type of organization and its energy uses;b) the complexity of process and their interactions;c) the competence of personnel; andd) the maturity of organization’s management system.A.5.2.2 Control of documentsThe intent of 4.5.2.2 is to ensure that the organization establishes and maintains documentation in a mannersufficient to implement the energy management system. The primary focus of the organization should be onimprovement of energy performance and on enhancing its energy management system implementation, noton a complex document control system.A.5.3 Operational controlAn organization should evaluate those of its operations that are associated with its identified significant energyuses and ensure that they are conducted in a way that will improve organization’s energy performance, inorder to fulfill the requirements of its energy policy and meet its objectives and targets. This should include allparts of its operations, including maintenance activities. As part of the energy management system providedirection on how to make the system requirements part of day-to-day operations, the organization should usesome kind of procedures, where applicable, to control situations where the absence of those procedures couldlead to deviations from the energy policy and the objectives and targets. Those procedures should includedistinct criteria for the operation and maintenance such as normal operating parameters such as temperature,pressure etc. They should also include operations such as start-up and shut-down.A.5.4 CommunicationEffective internal communication can be essential to ensure the successful implementation of the energymanagement system. Relevant and regular information on the energy management system contributes tomotivating and committing employees to comply with the organization’s energy policy and take an active partin achieving the organization’s objectives and targets. Methods of internal communication may include regularwork group meetings, newsletters, bulletin boards and intranet sites.External communications about its energy management system and energy performance are voluntaryactivities to an organization however the organization should recognize that those external communicationsmay have a great deal of benefits for the organization such as decrease of social risks and improvement oforganization’s reputations.Internal and external communication should address issues including: • energy policy, objectives and targets of the organization; • opportunities for individuals to contribute; • information about current energy uses and the trends within the organization;22 © ISO 2009 – All rights reserved
  30. 30. ISO/CD 50001 • compliance with legal and other requirements to which the organization subscribes; • opportunities for improvement, both organizationally and individually; • financial benefits from energy management activities; • other benefits i.e. environmental, social etc.; • contact persons to approach for further details or to contribute to energy improvement activities.A.5.5 DesignWhen designing any new or modified energy consuming systems, processes and facilities which have thepotential impact on the significant energy use, an organization should consider energy-conscious designwhich include best available technologies, where appropriate, and technology trends. This promotes greaterawareness of technology options and can move the organization toward more innovative and energy efficientdesigns. It might be useful for an organization to consider use of some formal guidelines as informationtogether with the guidelines which the organization has developed.Energy conscious design should ensure that: •a thorough analysis of the energy use is performed at the very first stage of design projects; • an energy assessment is subsequently carried out during relevant design stages where appropriate (tenders, detailed design, equipments selection, building design, delivery, commissioning etc.); • the tasks of those responsible in relation to energy conscious design should be clearly defined.A.5.6 Purchasing energy services, goods and energyA.5.6.1 Purchasing of energy services and goodsEnergy conscious purchasing ensures that energy performance is considered when decisions are made forthe purchase of equipments and energy services and goods. Where purchasing has the potential to impact toa significant degree on the energy uses, then energy performance should become part of the evaluationcriteria. Suggested purchasing can include: • companywide purchasing policies where applicable; • purchasing guideline i.e. criteria to be followed if proposed equipments or energy services have the potential to increase energy use by more than prescribed level; • detailed energy assessments as required; • communication to suppliers and contractors organization’s energy policy.A.5.6.2 Purchasing of energyNo guidance at this time.A.6 Checking performanceA.6.1 Monitoring, measurement and analysisMonitoring and measurement is the management of energy use by means of regular comparisons of actualand expected consumption.© ISO 2009 – All rights reserved 23
  31. 31. ISO/CD 50001Monitoring and measurement should be appropriate to the needs of the organization and should facilitate theanalysis of energy use (for example processes, systems and facilities), variations over time, achievement oftargets, etc. This means that the significant energy use should be assessed and evaluated at a frequency thatallows energy performance indicators (EnPI) to be established (e.g. kWh per unit of production and/or kWhper m2 floor area).The organization should use the accurate practicable method of ‘expected’ consumption. This implies that theorganization should use appropriate calculation methods whereby the effects of weather, product mix,occupancy rate or other influences do not distort the result.Comparison between actual and expected consumption will highlight unexpected deviations and may allowhidden waste to be detected.It is accepted that the organization will not necessarily have sufficiently comprehensive metering installed, andthat introducing it will potentially be costly, time-consuming, and disruptive. However, where appropriate, itshould have a demonstrable plan for improving the provision of meters.The organization should be able to justify the relevance of the measurement frequency applied in relation tothe identified energy consumption.Based on the nature and scale of the organisation, different measurement intervals may be used. For someorganizations weekly intervals would be appropriate. Some may wish to operate real-time, per shift, daily,monthly or less frequent measurements.Examples of monitoring and measurement include the following activities: • ongoingmonitoring and recording of the significant energy consumption and associated energy factors; energy factor looks like new word, so we should be careful for its use • summarising the significant energy consumption in the form of key figures; • comparison of actual and expected energy consumption; • intervention in the case of deviation from the expected energy consumption.The organization should plan monitoring and measuring of all significant energy consumption and otherenergy factors (e.g. outside temperature, occupation rate). These plans should include a description of thefollowing:a) how significant energy consumption and energy factors are measured and recorded;b) the extent of monitoring, including the frequency of measurements; calibration and maintenance ofmeasuring equipment;c) roles and responsibilities of relevant personnel;d) how expected energy consumption is calculated in relation to energy factors.In order to identify unnecessary energy use, monitoring and measurement plays the most important role.Shown below is an example of the best practices for the monitoring and measurement.In order to improve energy efficiency, it is required to identify an unnecessary energy use and take actions toreduce it. Monitoring and measurement should be conducted as frequently as possible.Frequent and continual monitoring and measurement help:Improving the reliability of checking performance;Identifying the transient unnecessary energy use caused by operating schedule in the short term;24 © ISO 2009 – All rights reserved
  32. 32. ISO/CD 50001Identifying the increasing unnecessary energy use caused by the deteriorations of facilities or equipments inthe long term;It also becomes effective tool for improvement thorough operation control. Examples for these continualroutine monitoring and measurement are as follows. 1. Energy Performance Indicators (EnPIs) should be measured for individual facility and equipment of significant energy use. These individually-measured EnPIs should be monitored continuously, which may vary over time. By investigating the causes of the variation, unnecessary energy use can be identified. Visualization of monitoring and measurement results facilitates to identify variations of EnPI. (An example of the visualization is shown in Figure A.2.) Figure A.2 — Identify the variation of the EnPI (Specific Energy use : kWh / unit )Furthermore, unnecessary energy use caused by deterioration of facilities and equipment can be identified bymonitoring the variation of time-averaged-EnPIs or moving-averaged-EnPIs over a long period of time. 2. Measured results of energy use and EnPIs should be collected at individual division basis of an organization and disclosed to all members of an entire organization. This disclosure is expected to further promote consciousness for improved energy efficiency by the principle of competition among divisions. For example, it is prompted to stop unnecessary operation of facilities and equipment.A.6.2 Evaluation of legal/other complianceThe organization should establish, implement and maintain procedures for monitoring the compliance withlegal and other requirements to which the organization subscribes, relating to the significant energyconsumption. Records of these results should be retained.A.6.3 Internal auditThe purpose of an internal audit is to carry out a systematic review of the energy management system andassess whether the system operates in accordance with the organization’s own requirements together withthose of the Energy management system standard. An internal audit procedure(s) should addressrequirements for defining the scope of the audits, the frequency and scheduling of audits, how audits are to beconducted and the training required for auditors. The procedures should also consider how audit findings arerecorded and reported and how any required corrective action is managed.Examples of subjects for consideration by internal auditing include: • proper implementation of energy management programmes, processes and systems;© ISO 2009 – All rights reserved 25

ISO/CD 50001 • opportunities for continual improvement; • capability of processes and systems; • use of information technology.Internal audits may be performed by employees of the organization and/or by external parties appointed bythe organization. In both cases the person or persons performing the audits are qualified, experienced,objective, impartial and independent of the area of the organization to be audited.The energy management system should typically be reviewed and audited on an annual basis as a minimum,where applicable. The results of the internal audit should be documented and communicated to seniormanagement.A.6.4 Nonconformity, corrective, preventive and improvement actionsA.6.4.1 NonconformitiesThe organization should ensure that nonconformities are investigated and appropriately taken action.Nonconformities exist when the organizations energy policy, objectives, targets, programmes or documentedprocedures are not complied with.A.6.4.2 Corrective and preventive actionThe organization should: • identify the cause of the non-conformance or potential non-conformance; • take the appropriate action to correct the non-conformance; • initiate the action required to prevent recurrence of the non-conformance; • change the documented procedures if necessary to ensure that they are consistent with new initiatives or actions; • identifywho is responsible for recording non-conformances and how they are recorded, and ensure that the process of corrective and preventive action is initiated; • retain all relevant documentation in accordance with legal and/or documented time frames.A.6.5 Control of recordsThe purpose of recording is to ensure that the necessary documentation is provided to substantiate theachievement of targets, action plans and other requirements of the energy management system.The extent of the documentation may vary according to each organizations requirements. These recordshave to include for a minimum (as a results of the requirements in this standard):a) Energy profile;b) Action plan;c) Method for determining significant energy use;d) Method for identification and update of indicators;e) Energy baseline26 © ISO 2009 – All rights reserved
  34. 34. ISO/CD 50001f) Training needs and actions taken in this respect;g) Competency: Education, training or experiences of people related to signicficant energy use;h) Design (and or purchase): energy performance evaluation for design (and or purchase), modify orrenovating energy systems, equipment, buildings;i) Key characteristics of operation that determine energy performance;j) Records of monitoring and measurement;k) Records for calibration of equipment used for measuring and monitoring;l) Legal and other compliance evaluation;m) Corrective and preventive actions;n) Results internal auditso) Management reviewAdditional records determined necessary by the organization may also be kept. Examples:• information about relevant laws and regulations;• applicable training records;• relevant energy management communication material to all stakeholders such as press releases,awareness campaigns, presentations, websites, awards, etc.;• communication of energy policy to contractors, subcontractors and suppliers;• dates of inspection and servicing of energy using equipment;• procurement of energy efficiency equipment.All records kept should be legible, identifiable, traceable and readily retrievable. These records coulddemonstrate conformity to the requirements of the organization’s energy management system.A.7 Review of the energy management system by top managementManagement review is the act process of the Plan –Do- Check-Act process. As such it is not a passive reviewof information, but rather a mechanism to ensure that the organizational objectives and the direction of theenergy management system are aligned and the actions are taken to ensure continual improvement of theenergy performance of the organization. The management review ensures that the individual elements andoverall operation of the energy management system are evaluated in a critical manner in relation to the abilityof the system to conform to the energy policy and achieve the energy targets and demonstrate energyperformance. The management review should engage stakeholders at the necessary levels within theorganization to ensure success and appropriate resources. An organization determines the intervals that areappropriate for management review. Management review may be accomplished through a single session or aseries of sessions and typically covers the required inputs and outputs at least on an annual basis.Management review may be accomplished through technological options such as electronic meeting tools,face to face sessions or other means appropriate to the organization. This process does not require adocumented procedure. Top management can use the management review process as a powerful tool in theidentification of opportunities for energy performance. The schedule of reviews should facilitate the timelyprovision of data in the context of strategic planning for the organization.© ISO 2009 – All rights reserved 27
  35. 35. ISO/CD 50001One of the key functions of the management review is to assess the overall suitability, adequacy andeffectiveness of the system. Suitability indicates that management system is appropriate for the organization,a decision that is typically based on the inputs related to the policy, as well as information on any changes toprocess, significant energy uses or major changes in legal obligations or other requirements to which theorganization subscribes. Adequacy indicates that management system is able to meet the organizationalrequirements and needs and is typically based on the inputs related to review of energy performance andfollow up actions from the previous meetings along with other information on the performance of the energymanagement system the organization considers relevant. Effectiveness indicates that energy performanceand continual improve results are being achieved. This decision is typically based on the inputs such asreview of energy performance, extent to which objectives and targets have been met, audit results, projectedenergy performance, and recommendations for improvement. It is important that the management reviewinformation for effectiveness consider the energy performance of the organization over time and anynecessary adjustments to the baseline for comparative purposes.A.7.1 Inputs to management reviewIn addition to the required inputs, many organizations may include other relevant information such as but notlimited to:• changes that will influence energy consumption in the coming year;• changes that will be necessary in the management system processes in the coming year;• potential to consider new technology or alternative energy sources;• plans for energy assessments and other planning tools necessary to ensure continual improvement of theenergy management system.• Validation plans for the action plans recently completed and those planed for the next year.Review of the Energy performance indicators that will be used to communicate the progress of energyperformance to the organization.A.7.2 Outputs from management reviewSelected output should be communicated to demonstrate to the people in the organization how themanagement review process leads to new objectives that will benefit the organization. The outputs shouldalso include the actions to be taken as a result of the management review process, including assignment ofresponsibility, authority, accountability, and timelines for the actions to be completed.28 © ISO 2009 – All rights reserved
