Energy efficiency has grown to a critical competitive factor of production systems. Governmental and nongovernmental organizations as well as commercial consultants provide solutions for energy management. However, these institutions only draw up standards and guidelines to increase efficiency and do not provide actual measures. Due to inconsistencies in the understanding of energy efficiency, solutions are hardly comparable. Moreover, enterprises focus on knowledge about cost-efficient production systems, whereas knowledge about energy efficiency is put in second place, as the objective of environmental sustainability commonly is induced extrinsically. This leads to inefficiencies in the selection and application of energy efficiency measures. In this paper we provide an approach for using ontologies for selecting energy efficiency optimization measures. Through the use of ontologies, a categorization of energy efficiency measures is facilitated. In addition, ontologies are capable to describe relations between the concepts of the knowledge base and thus allow reasoning. Hence, the given approach is able to guide a nonexpert user through the process of energy efficiency measure selection and moreover provides benchmark data for eligible solutions. Within this paper, we illustrate the application of the approach based on the examples of electric drives and pump systems. [ABSTRACT FROM AUTHOR] |
