- Abstract:
The building sector is responsible for almost one-third of the total final global energy consumption, meanwhile 70% of existing buildings are not operating energy efficiently. The domain of Facility Management (FM) has a strong influence on the optimal energy consumption of existing buildings. However, when buildings are re-designed, FM Knowledge is minimally used or often ignored altogether. As a result, many newly refurbished buildings fall short of expectations and consume more energy during operation than initially calculated.Due to the last years’ research development in the area of Building Information Modeling (BIM), establishing a specialised BIM-supported Knowledge Management System could solve this long-standing problem. However, existing studies targeting BIM-supported Knowledge Management and BIM-supported Knowledge Management Systems are still limited today. Accordingly, the presented work provides first of all a methodological framework, founded on the systematic alignment of Knowledge Management, Knowledge Engineering, and System Engineering principles, by which the development of such a system can be executed.By applying this methodological framework, the research introduces the system’s development progress in five consecutive layers, encompassing together an ontology-based theoretical framework. Respectively, first of all, an enterprise ontology is established, forming the backbone of the system development. This ontology provides a holistic communication base for people about the essential knowledge processes and the related BIM-supported systems. Second of all, by the navigation of this ontology, an FM Domain Ontology is conceptually developed, enabling the systematic codification of FM Knowledge, especially in terms of buildings’ energy performance. Last of all, by utilising this domain ontology, an application ontology is theoretically established, forming the underlying knowledge base of the system, which is used for rule-based code compliance checking purposes.The validation of the ontology-based theoretical framework, which indirectly validates the methodological framework, is performed on one of the campus buildings of the Hochschule für Technik und Wirtschaft Berlin. The results showed that by implementing the BIM-supported FM Knowledge Management System, Facility Managers and Design Experts can smoothly collaborate regarding building energy performance questions, thus proactively ensuring the optimal operational energy use of existing facilities in the future. Accordingly, the presented research provides a groundwork where an integrated and accelerated design process is established, where the knowledge of Facility Management can gain a significant role in renovative design decisions.
