Ontology engineering for iso 50001-based industrial energy management systems
This paper presents an implemented prototype of the ontoEnMS ontology, which formalizes selected ISO 50001 energy-management knowledge and connects it with manufacturing and measurement contexts. A hybrid METHONTOLOGY/NeOn workflow is used to develop an OWL 2 DL TBox and an enterprise ABox. The model represents energy reviews, significant energy uses (SEU), energy baselines (EnB), energy performance indicators (EnPI), operational control and improvement actions. Alignment hooks connect ontoEnMS with an author-developed IEC 62264-based OntoMES model and SOSA/SSN without asserting unjustified class equivalence. The prototype is checked in Protégé 5.6.4 through HermiT/Pellet consistency reasoning and four competency questions implemented as SPARQL query patterns. An industrial mining-and-processing ABox links production units, equipment, electricity meters, observations and area-level EnPI values. For area K2-B, 18.40 kWh/t is compared with a 17.92 kWh/t baseline, identifying a 0.48 kWh/t (2.68%) adverse deviation. SHACL completeness constraints are specified as the next closed-world validation layer rather than reported as executed tests.
