In order to stay competitive in a globalized market, manufacturers of investment goods and high-grade consumer goods have to increase efficiency, both for their products and for their processes. Consequently, resource and energy efficient production is a topic of highest interest in industry and science.

The paper discusses selected research activities and findings of the large-scale cooperative research project InnoCaT®, funded by the German Federal Ministry of Education and Research. This innovation alliance consists of 30 subprojects and more than 60 partners - automobile OEMs, equipment suppliers, technology partners, software solution providers and three Fraunhofer Institutes as lead partners for applied research.

The research consortium acts with a general view to the total manufacturing process chain of car body structures. Scientific studies leads to answering the question, whether if and how painted car bodies are producible with half of the energy and resources needed today. Fields of research are production technologies and systems for tool and die making, press shops, body shops and paint shops and, to be considered more in detail in this paper, factory and process planning as well as ICT related topics.

As a specific aspect of the paper there is a focus on the holistic planning of energy efficient production in car plants. Specific planning tools for components and parts, manufacturing processes, logistics, infrastructure, media supplies and factory buildings have to interact with each other to enable a reliable prediction and global optimization of energy consumption. For this, an approach for domain-spanning exchange of energy related information as well as extensions of a discrete event simulation tool in sense of “energy sensitivity” are presented.
