A performance assessment ontology for the environmental and energy management of buildings

Narrowing the performance deficit between design intent and the real-time environmental and energy performance of buildings is a complex and involved task, impacting on all building stakeholders. Buildings are designed, built and operated with increasingly complex technologies. Throughout their life-cycle, they produce vast quantities of data. However, many commercial buildings do not perform as originally intended. This paper presents a semantic web based approach to the performance gap problem, describing how heterogeneous building data sources can be transformed into semantically enriched information. A performance assessment ontology and performance framework (software tool) are introduced, which use this heterogeneous data as a service for a structured performance analysis. The demonstrator illustrates how heterogeneous data can be published semantically and then interpreted using a life-cycle performance framework approach.European Commission - Seventh Framework Programme (FP7)Irish Research CouncilProgramme for Research in ThirdLevel Institutions (PRTLI) Cycle 5European Regional Development Fund (ERDF)Marie Curie FP7 Integration Gran
