Energy Management Systems


The international standard ISO 50001, Energy management systems —Requirements with guidance for use, enables organizations to establish the systems and processes necessary to improve energy performance, including energy efficiency, use and consumption.

Its overall aim is to put in place systems and processes to provide significant energy usage reductions resulting in an associated decline in costs and greenhouse gas emissions achievable through the systematic management of energy. The standard is consistent with the ISO 9001 and ISO 14001 management systems presently adopted throughout Irish industry.

The technical principles of ISO 50001 are critical to the successful implementation of the standard and in delivering desired energy savings. A Management Systems certification body must be able to demonstrate its competence to assess and certify an energy management system that conforms to ISO 50001.

INAB accredits certification bodies to the international standard, ISO 17021-1 on demonstration of their competence to carry out energy management system conformity assessments related to products, processes, systems or people. INAB publishes a schedule of accreditation for each accredited certification body which specifies industry sector codes within which the body has demonstrated its competence.

The certification body must comply with ISO 17021-1 and any associated guidance published by the International Accreditation Forum, IAF and the European Co-operation for Accreditation, EA.

ISO 17021-1 has a number of requirements for organisational structure, quality management system elements, competence of personnel, confidentiality, etc. and the certification body must be able to demonstrate compliance with all of these requirements.
