ISO 50001 helps organisations to introduce, operate and continually optimise a comprehensive energy management system (EnMS). The successful implementation of this systematic approach can optimise energy use by improving energy performance, reducing energy consumption and/or increasing energy efficiency.


certificates will no longer be valid. Fortunately, for those businesses which are already certified under ISO 50001: 2011, a conversion to ISO 50001: 2018 can be achieved as part of a repeat audit or a scheduled surveillance audit.


A


ISO 50001:2018 provides a framework of requirements for organisations to: • Develop a policy for more efficient use of energy.


• Fix targets and objectives to meet the policy.


• Identify, measure, monitor and analyse the key characteristics of operations affecting energy performance.


• Facilitate data-based analysis and decisions about energy use.


• Measure the results. • Review how well the policy works. • Continually improve energy performance and energy management system


The updated ISO 50001 includes a greater emphasis on the


responsibilities of top management and highlights the importance of instilling a cultural change in the organisation. The ISO 50001:2018’s requirements are described in clauses 4 – 10.


Clause 4 – Context of the organisation


David Goodfellow, UK Business Assurance Manager at TÜV SÜD, a global product testing and certification organisation.


ISO 50001 requires that internal and external issues are considered as part of the organisation’s energy planning process. This includes understanding the relevant needs and expectations of interested parties (those impacted by the organisation) in relation to energy performance and the EnMS. The organisation must also ensure that it has access to and considers relevant legal and other requirements related to its energy efficiency, use and consumption.


Clause 5 ­ Leadership


ISO 50001 demands greater commitment from senior management. It must ensure the formation of an energy


management team, and that roles, responsibilities and authorities are assigned and communicated. They must also ensure that the EnMS’s requirements are integrated across business processes and that it is compatible with the wider strategic direction. Unlike the old version of the standard, this responsibility can no longer be delegated.


Clause 6 – Planning


The energy planning and review process will help to identify the activities and processes that impact energy performance, and how this can be continually improved. Opportunities and risks must be identified, with the plan covering how they will be addressed, as well as their integration and

implementation within the EnMS, and how effectiveness can be evaluated. This should include the establishment of objectives and energy targets, as well as


conducting an energy review which must be updated regularly and in response to any major changes. The organisation must also determine the energy performance indicators (EnPIs) that measure energy performance, so that improvements can be monitored. Data should include relevant variables for significant energy uses (SEUs); energy consumption related to SEUs and the organisation; operational criteria related to SEUs; static factors; and data specified in action plans.


Clause 7 – Support


The appropriate resources must be available to establish, implement, maintain and continually improve energy performance and the EnMS. The EnMS must also be actioned by competent people. There is a requirement to retain evidence of workers’ competence, while ensuring appropriate education and training, as well as awareness raising about energy performance issues. There must also be a process for communicating information relevant to the EnMS, both internally and externally, as well as documented evidence of these practices.


Clause 8 – Operation


This covers the planning, implementation and control of the processes related to the SEUs identified in the energy review, and what is required to implement the actions during the objectives setting phase.


To achieve this, a process criteria must include the effective operation and maintenance of facilities, equipment, systems and energy- using processes, where their absence can lead to a significant deviation from intended energy performance. These criteria must be communicated to the relevant people that are under the control of the organisation. The organisation must also ensure that the processes are controlled, as laid out in the criteria. Documented evidence must also be kept, to show that the processes have been carried out in


accordance with the plan. The organisation must also ensure that outsourced SEU’s or processes are controlled.


During the design of facilities, equipment, systems and energy- using processes, the organisation must consider if there will be any significant impacts on energy performance over the operating lifetime, to identify improvement opportunities and operational control. It must also establish criteria for evaluating the energy performance for any energy- consuming products, equipment and services that are procured, if this is expected to have a significant impact on the organisation’s energy performance.


Clause 9 – Performance evaluation


Organisations must ascertain what must be measured and monitored, by whom and with what frequency, to give an indication of how the energy management system is performing. This must include internal audits of the EnMS at planned intervals. Documented evidence must be retained - the standard gives in-depth detail about what such a review should include.


Clause 10 – Improvement


Key to the success of an ISO 50001 management system is the ability to demonstrate continual energy performance improvement.


Opportunities for improvement must therefore be identified, appropriate action taken and nonconformities reported.


In most cases it is advisable to integrate the EnMS into an existing ISO 14001 environmental management system, or an ISO 9001 quality management system, so that synergies can be exploited and the organisation can leverage existing management system compliance investments.


For those transitioning between ISO 50001:2011 and ISO 50001:2018, an audit will enable organisations to focus on the key areas that require action. A gap analysis will identify nonconformities and differences, as well as weaknesses in terms of the requirements of the new standard. ISO 50001 enables organisations of any size to systematically optimise energy performance and promote more efficient energy management. The ISO 50001 EnMS framework can improve bottom lines through systematic, data-driven and fact- based processes that improve energy efficiency and environmental performance. With the increasing cost of energy, it will help


organisations to objectively evaluate their energy consumption, optimise costs and reduce negative environmental impacts.
