The actual energy policy of the EU and the regulations which derive from that, lead to a variety of challenges for the industry in general. Energy-intensive companies, like foundry companies, are encouraged to increase energy efficiency in order to fulfill current and future legal targets. The objective of this work is to develop a framework or model, which helps to achieve those targets through the analysis and evaluation of energy consumption and energy efficiency. Several benchmarks are defined, which can be carried out with the model results. First, all elements of the model development are shown. A data acquisition methodology, including a questionnaire and data sheets, is developed, followed by the definition of the model design. The model design consists of two approaches containing an economic and a technological focus. Indicators for evaluation purpose are defined and the applicability is shown through the application to a case study in an Austrian foundry. All relevant indicators are determined, which results can be used for evaluation and optimization purposes. Contradictory results show that future research should further develop the model. For optimization purpose, methods like Exergy- and Pinch analysis should be implemented.
