FEATURE ENERGY MANAGEMENT
Reducing energy costs with ISO 50001 I
SO 50001 enables organisations of any size to systematically optimise energy performance
and promote more efficient energy management. The ISO 50001 energy management system (EnMS) framework can improve bottom lines through systematic, data-driven and fact-based processes that improve energy efficiency and environmental performance. A revised edition of ISO 50001 standard was
released in 2018. Following a three-year transition period, from 20 August 2021 ISO 50001:2011 certificates will no longer be valid. The good news for those businesses which are already certified under ISO 50001: 2011 is that conversion to ISO 50001: 2018 can take place as part of a repeat audit or a scheduled surveillance audit. 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 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

With the increasing cost of energy, organisations need to objectively evaluate their energy consumption, to maintain or reduce costs and lessen the negative impact on the environment. David Goodfellow, UK business assurance manager at TÜV SÜD, explains how ISO 50001 can help you reduce your energy costs
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
