Success factors and organizational approaches for the implementation and the operational use of energy management systems according to ISO 50001

Due to rising energy costs, increasing global competitive pressure and the demand for environmentally friendly products companies all over the world consider the implementation of an energy management system (EnMS) to meet future challenges. The purpose of this paper is to identify main success factors for the effective implementation, operation and certification of an EnMS in accordance with ISO 50001, which represents the fastest growing standard for management systems in the world. For that reason a survey among already certified German companies has been conducted focusing on organizational, teambuilding and technical aspects. The study provides best practice knowledge and gives interested companies the advantage to benefit from both the positive experiences of the participants as well as to prevent potential contra productive activities during the implementation, certification and operation of an EnMS. Results indicate that EnMSs are most commonly built on already existing management structures and therefore staff organization is crucial for the success of the project. Still, monetary aspects such as energy related cost savings seem to be the decisive criterion for the operation of an EnMS. Regarding teambuilding aspects specific technical expertise is required which leads to cross-functional teams focusing on the field of production. In addition key technical and administrative measures for an effective EnMS were identified.
