Energy management is one of the great challenges of the industry in the next years. Energy becomes more and more to a critical resource. Until now, enterprises need to implement energy management system with nearly no guidance. In the following paper we present the foundation of a reference model-based method that serves for setting up energy management systems in various industrial sectors. The goal is to support reduction emission and cost reduction as well as certification needs. In contrast to previous approaches, this approach enables a model-based certification and allows an automation of activities of the process of supervision of the consumption of energy and the appropriate reengineering of business processes.
