ISO/TC 301/WG 1 - Energy management

This document gives guidance for organizations on establishing a phased approach to implement an energy management system (EnMS). This phased approach is intended to support and simplify the implementation of an EnMS for all types of organizations, in particular for small and medium-sized organizations (SMOs). This document gives guidance on the use of twelve core elements with four levels of maturity for each element to establish, implement, maintain and improve an EnMS that results in energy performance improvement. It enables the user of this document to implement a phased approach to achieve a level of energy management appropriate to its objectives and to build a strong foundation which can subsequently be extended towards meeting the requirements of ISO 50001:2018. This document is consistent with ISO 50001:2018 but does not cover all of its requirements.

This document gives practical guidelines and examples for establishing, implementing, maintaining and improving an energy management system (EnMS) in accordance with the systematic approach of ISO 50001:2018. The guidance in this document is applicable to any organization. This document does not provide guidance on how to develop an integrated management system. While the guidance in this document is consistent with the requirements of ISO 50001:2018, it does not provide interpretations of those requirements.

This document specifies requirements for establishing, implementing, maintaining and improving an energy management system (EnMS). The intended outcome is to enable an organization to follow a systematic approach in achieving continual improvement of energy performance and the EnMS. This document: a) is applicable to any organization regardless of its type, size, complexity, geographical location, organizational culture or the products and services it provides; b) is applicable to activities affecting energy performance that are managed and controlled by the organization; c) is applicable irrespective of the quantity, use, or types of energy consumed; d) requires demonstration of continual energy performance improvement, but does not define levels of energy performance improvement to be achieved; e) can be used independently, or be aligned or integrated with other management systems. Annex A provides guidance for the use of this document. Annex B provides a comparison of this edition with the previous edition.
