Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 50004 : 2020 ‘Energy management systems — Guidance for the implementation, maintenance and improvement of an ISO 50001 energy management system’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Energy Management and Energy Savings Sectional Committee and approval of the Mechanical Engineering Division Council.

This standard was originally published in 2014 and was identical with ISO 50004 : 2014. The first revision of this standard has been undertaken to align it with the latest version of ISO 50004 : 2020.

The major changes in this revision are as follows:

a) The document has been restructured as per the high level structure (HLS) for Management System Standards, which helps to ensure a high level of compatibility with other MSS, including the addition of context of the organization and risk;

b) Stronger emphasis has been placed on the role of top management;

c) Exclusions of energy types have been clarified;

d) The energy review has been clarified;

e) Details on the energy data collection plan and related requirements have been added (previously the energy measurement plan);

f) The EnPI and EnB text has been clarified to provide a better understanding of these concepts;

g) The examples based on the experience of implementation have been included;

h) The format has been modified to remove the practical help boxes and integrate the information within the text; and

j) The annexes have been removed.

The text of ISO (IEC) standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
