ENERGY MANAGEMENT FEATURE
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 SEUs 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. 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. ISO 50001 provides every type and size of organisation with a systematic approach to monitor and reduce energy consumption, helping them to increase energy efficiency and improve profitability.
