Abstract
The interoperability of information from design to operations is an acknowledged challenge in the fields of architecture, engineering and construction (AEC). As a potential solution to the interoperability issues, there has been increasing interest in how linked data and semantic web technologies can be used to establish an extendable data model. Semantic web ontologies have been developed for the AEC domain, but an ontology for describing the energy and mass flow between systems and components is missing. This study proposes the Flow Systems Ontology (FSO) for describing the composition of flow systems, and their mass and energy flows. Two example models are expressed using FSO vocabulary. SPARQL Protocol and RDF Query Language (SPARQL) queries are performed to further demonstrate and validate the ontology. The main contribution consists of developing FSO as an ontology complementary to the existing ontologies. Finally, the paper introduces a roadmap for future developments building on FSO.

Summary
The stakeholders in the architecture, engineering and construction (AEC) industry collaborate on complex, multidisciplinary projects that span years and produce large quantities of information besides the finished physical product. Efforts to improve interoperability using the semantic web technologies include the development of ontologies to describe common semantic vocabularies To this end, the community group has published ontologies for the AEC industry. While ontologies for describing certain aspects of the AEC domain have been developed and published, a common standardized ontology to describe the energy and mass flow between the components is missing Such an ontology is needed to support the linked data de scriptions of Heating, Ventilation and Air Conditioning (HVAC) systems. The vision is to provide a common foundation for describing flow systems in linked data This would enable extensions that focus on more specific information perspectives for ap plications such as hydraulic simulation suites, building energy perfor mance simulation (BEPS), building analytics, and diagnostics.
