Abstract This paper presents the development of a conceptual map regarding energy management applied to industry. The energy issue is currently of great relevance, especially for the so-called energy-intensive industries related to high energy consumption and their associated environmental impacts. The present research is characterized as a basic, exploratory approach justified by the need to build knowledge on the subject of energy management in industry. The methodology provides for the use of a computational tool called CMap Tools, which assists in the graphic representation of the proposed conceptual map. The conceptual map based on the ISO 50001 standard and on successful energy management practices described in the scientific literature is directed toward a process design covered by the managerial discipline called Business Process Management. The conceptual map is intended to clarify the relationships that are established between the intra-organizational and main external stakeholders involved in an energy management system. Owing to the way internal areas and external organizations relate, the representation structure using a “Spider” is the most appropriate. The work developed presents an energy management system for an energy-intensive industry in a clear (conceptually and visually), orderly, unified, harmonious, and balanced manner indicating the distribution of its elements, and serves as an initial step in the creation of an ontology for this area of knowledge.
