Case studies Analysis of base load consumers Production of pharmaceutical packaging Employees: <500Energy cost [€/a]: approx. 3.5 mil With a systematic reduction of the base load the energy costs have been reduced by 11,3 %. Support for an enterprise network Various industries Employees: <50 to approx. 6,000 Energy costs: [€/a]: approx. 200,000 € to 10 million € As part of a corporate network, support and energetic-technical advice for 14 companies took place. Introduction of an energy management system in 4 weeks Manufacturing of metal products Employees: <200Energy costs: [€/a]: approx. 5 million Thanks to a good data base and an intensive collaboration, within 4 weeks an energy management system has been introduced, reductions in the EEG apportionment have been achieved and efficiency potentials have been revealed. Simultaneous introduction of multiple management systems Manufacturing of paper products Employees: 500 – 2,000Energy costs [€/a]: approx. 3.4 millions WIth the introduction of an energy and an environmental management system and the integration of these systems in the existing quality management system, relief claims from the EEG surcharge were asserted and efficiency potentials have been revealed. Executing energy audits with a multi-site certification Mechanical engineering Employees: >2,000Energy cost [€/a]: approx. 4.2 million While executing an energy audit with the multi-site-procedure we were able to reduce the amount of locations to be audited from 35 to 6 and to uncover transferrable efficiency potentials. Optimization of circulation processes Chemical industries Employees: <200Energy cost [€/a]: approx. 1.5 million With the help of material flow cost accounting and a comparison of costs of in-house production vs. the procurement of the product, we were able to evaluate the economic efficiency of a recycling process and the meaningfulness of a combined heat and power plant to generate electricity. Economic efficiency of bottling Brewery Employees: <200Energy cost [€/a]: approx. 800,000 Aside from mapping the energy and material flows of the brewing process, a comparison of using returnable bottles and disposable bottles has been made.
