Entwicklung eines KPI-basierten Energiemonitoringsystems für die Liebherr Werk Telfs GmbH unter Berücksichtigung der ISO 50001:2018

Current climate targets and volatile energy prices impose major challenges for companies in all industries. DIN EN ISO 50001:2018 was created with the intention of supporting companies in introducing measures for energy efficiency. In this context, energy management systems are an essential factor for companies to improve energy use and energy cost development, increase energy-related performance, and contribute to climate protection and sustainability at the same time. As part of this work, energy management systems according to DIN EN ISO 50001:2018 were examined and analysed specifically in their application to industrial processes. The definition of energy indicators plays an important role, as these indicators are a requirement during the course of energy monitoring in companies to set and achieve goals. The theoretical part considers DIN EN ISO 50001 for energy management systems and DIN ISO 50006 as a guideline for dealing with energy performance indicators. Hereby the creation of indicator systems is the main focus. Furthermore, selected examples and case studies are examined and from them the greatest challenges and best practices in energy management and energy monitoring are derived. The introduction of an indicator system at a mechanical engineering company, the energy management system of an automotive manufacturer and the integration of energy management in industry 4.0 are also discussed. The practical part of this thesis describes the development of an EnPI-based energy monitoring system for Liebherr Werk Telfs GmbH. At first, the factory, its energy management system and its energy consumption structure are analysed in detail. After that, significant energy users are identified using a top-down approach. The existing EnPIs are evaluated regarding their informative value and their practicality in application, and suggestions for their improvement are provided. For the identified significant energy users energy indicators are defined and explained. Those can be applied throughout the factory and for specific sections of it. Using the available data, the indicators are also monitored for the past years or months. At the end of the practical part, recommendations for actions are provided to Liebherr Werk Telfs GmbH, which have proven to be useful or necessary through the companionship of the company during the development of its energy monitoring system. Additionally, suggestions are offered that can help optimize the company¿s energy management system as part of the continuous improvement process.
