The Environmental Impact Reduction obtained by implementing an Energy Management System. The advantages of using Energy Management and Energy Savings Standards when performing Industrial Energy Audits

Energy audits are used world-wide for developing energy efficiency projects. Industrial consumers have complex energy supply, generation and distribution networks and a variety of energy use installations. Romanian industrial companies became more interested in the last years in implementing Energy Management Systems in accordance with ISO 50001 standard. This paper presents a comparison of using the current way of developing energy audits and the concepts provided by the ISO group of standards, by quantifying the environmental impact reduction generated by each methodology. Authors pointed out that current legislation does not fully match the rigors of the ISO 50001 group of standards when evaluating the Energy Baseline (EB), the Energy Performance Indicators (EPI) or the Energy Performance Improvement Actions (EPIA), thus leading to a lower global energy efficiency improvement in the hypothesis of implementing all the recommended EPIAs [1]. Identifying and developing energy efficiency measures following the recommendations of the energy management and energy savings group of standards may be more consistent and less risky for the industrial company, which in turn can lead to an overall improvement of the Carbon Footprint [2]
