New recommendations for monitoring and follow-up of energy efficiency measures implementation

Scope

The present document aims to establish guidelines and good practices for the implementation of energy efficiency measures in industries, based on the results obtained from energy audits and Energy Management Systems (EnMS). Its purpose is to provide a best-practice framework enabling organisations to identify and implement energy improvements and energy transition path in a systematic, efficient manner and in alignment with the applicable energy efficiency and climate regulatory framework.
This document applies to industries across all sectors, and particularly to energy-intensive sectors. That is, sectors and companies carrying out mandatory energy audits or Energy Management Systems in accordance with national, European standards and International standards. It includes reference legislation and methodologies, as well as good practices and recommendations for the implementation of energy efficiency and energy transition measures, the monitoring of the implementation process, and the evaluation of the results obtained.
This document is intended for use after energy audits carried out under applicable national requirements or recognised standards such as EN 16247 (series) and ISO 50002-1. It uses as input the opportunities and measures for reducing energy consumption identified in the energy audit report and provides guidance for their selection, implementation, monitoring and verification. The document can also be used by organisations operating, implementing or considering an Energy Management System according to ISO 50001.
This document does not replace legal obligations, certification requirements or sector-specific permitting requirements. It provides practical recommendations to support decision-making, implementation control, measurement and verification, and management review.
