Abstract

This paper evaluates the potential of semantic technologies to facilitate building material circulation in the construction industry within the Circular Economy (CE) context. It suggests building material passports as a data source for the materials to be circulated and then integrates them by means of Linked Data. A common language is proposed to combine and re-use the material data in the CE with the creation of two ontologies: Circular Exchange Ontology (CEO) and the Circular Materials and Activities Ontology (CAMO).The ontologies annotate materials under a CE classification scheme and describe the elements required for material exchange to occur: actors, the activities they perform and the referents of these activities (resources, products, tools and waste). An evaluation of the ontologies is made by means of use case-driven SPARQL queries. Further, a wide-scale evaluation addresses how a decentralized data ecosystem can enable users to publish information and dynamically interact with different repositories to exchange materials. Results indicate that these ontologies can foster a circulation medium between diverse construction industry resources. Future work contemplates validation of both ontologies in a real-world-setting with computer scientists and companies in the construction sector in the Benelux area.
