Title:	Integrated representation of building service systems: topology extraction and TUBES ontology
Abstract:	This paper details parts of the work within the Energie.Digital project which aims at developing an integrated representation of building service systems consisting of technical characteristics, physical and functional semantics as well as operating states and state diagrams. This information needs to be machine- readable and linkable using a global identification key. The focus of this paper is set on the extraction and aggregation of the semantics of service systems from an Industry Foundation Classes (IFC) file and the development of an ontology based on Semantic Web principles within the environment of the Linked Building Data Community Group of the W3C. Integrale TGA-Beschreibung: Topologie-Extraktion und TUBES-Ontologie. In diesem Beitrag werden die aktuellen Ergebnisse des Forschungsprojekts Energie.Digital vorgestellt. Ziel des Projekts ist eine integrale digitale Beschreibung der technischen Gebäudeausstattung. Dies umfasst Informationen zu den physikalischen und funktionalen Verknüpfungen, den technischen Eigenschaften der Komponenten sowie zu Betriebsmodi und Ablaufdiagrammen. Diese Informationen müssen maschinenlesbar und über einen Anlagenkennzeichenschlüssel verlinkbar sein. Im Folgenden wird zum einen die Extraktion und Vereinfachung der topologischen Beschreibung der Systeme der technischen Gebäudeausrüstung aus einem IFC-Modell, anderseits die Entwicklung einer Ontologie beschrieben. Diese basiert auf den Prinzipien des Semantic Web und integriert sich in die Umgebung innerhalb der Linked Building Data Community Group des W3C.
