 INTRODUCTION

Faced with sustained rises in energy prices and increasing obligations to reduce CO 2 emissions (the European Energy Efficiency Directive [EED], the Tertiary Sector Decree, and regulatory GHG reporting requirements), industrial companies are required to manage their energy consumption in a structured and documented manner.

Developing an energy metering plan provides you with reliable consumption data. The next— –—and decisive—– —step is to identify areas where savings are technically and economically feasible, then prioritize them to focus investments on actions with the highest return on investment.

Energy managers, production engineers, maintenance managers, and executives at small and medium-sized enterprises (SMEs) and mid-sized companies: you want to implement a rigorous approach to improving energy performance in accordance with the requirements of the ISO 50001 standard (the “Planning” and “Energy Review” phases).

This practical guide will help you:

  • conduct a rapid assessment of energy-consuming areas at your site;

  • apply structured methods to identify energy-saving opportunities;

  • assess the savings potential and feasibility criteria for each action;

  • create a prioritization matrix to guide your investment decisions;

  • define a prioritized action plan and monitor its implementation.
