ISO 50001:2018 – Energy Management Systems

ISO 50001:2018 is the newly revised international standard for Energy Management providing the most robust framework for optimizing energy efficiency in public and private sector organizations.

The standard aims to help organizations continually reduce their energy use, and therefore their energy costs and their greenhouse gas emissions.

The main objective of the standard is to improve energy-related performance and energy efficiency continuously and to identify energy reduction opportunities. This systematic approach will help organizations to establish systems and processes.

Consistent energy management helps organizations to realize untapped energy efficiency potential. They will benefit from cost savings and make a significant contribution to environmental and climate protection, for example by the permanent reduction of CO2 emissions.

 

ISO 50001 provides a framework of requirements for organizations to:

  • Develop a policy for more efficient use of energy
  • Fix targets and objectives to meet the policy
  • Use data to better understand and make decisions about energy use
  • Measure the results
  • Review how well the policy works, and
  • Continually improve energy management.

 

 

The main changes compared to the previous edition are as follows:

  • adoption of ISO’s requirements for management system standards, including a high-level structure, identical core text, and common terms and definitions, to ensure a high level of compatibility with other management system standards
  • better integration with strategic management processes
  • clarification of language and document structure
  • stronger emphasis on the role of top management
  • adoption of context order for the terms and their definitions in Clause 3 and update of some definitions
  • inclusion of new definitions, including energy performance improvement
  • clarification on exclusions of energy types
  • clarification of “energy review”
  • introduction of the concept of normalization of energy performance indicators [EnPI(s)] and associated energy baselines [EnB(s)]
  • addition of details on the energy data collection plan and related requirements (previously energy measurement plan)
  • clarification of text related to energy performance indicators [EnPI(s)] and energy baselines [EnB(s)] in order to provide a better understanding of these concepts.

 

How Is ISO 50001 Energy Management Systems Implemented?

  • Organizations should follow the following steps to implement the ISO 50001 standard:
  • Inform employees and management about the key requirements and goals.
  • Provide education and training for relevant staff.
  • Perform a gap analysis to identify areas that need improvement.
  • Develop a project plan.
  • Designate project managers and team members.
  • Design and document the EnMS.
  • Implement the ISO 50001 EnMS.
  • Carry out an internal audit.
  • Have an ISO 50001 audit performed.
