Licensee MDPI, Basel, Switzerland.The European building industry is facing a strong increase in renovation processes, which are still non-cost-effective, involve unproperly coordinated stakeholders, are disturbing for the occupants, and cause important inefficiencies in the overall renovation process. In this context, digitalization and Building Information Modelling (BIM), as an enabler, is the key solution that may drive renovation interventions to ensure a more successful and leaner process, aiding the whole value chain of actors to achieve its full potential. This research describes the OpenBIM methodology applied in order to transform the implicit knowledge from the stakeholders involved in the building renovation process, not structured enough for automation, into an OpenBIM digital process based on the BIM standards. The outcomes of this research are the OpenBIM ready workflows that represent the renovation process and information requirements according to the involvement of different stakeholders rooted in the analysis of barriers, requirements, and needs. Those workflows are the basis for the future development of specific products and tools for boosting digitalization and interoperability in the renovation process.13357039enginfo:eu-repo/semantics/openAccessjournal article10.3390/app112110429Building renovationBIMInteroperabilityBPMNWorkflowsDigital constructionRetrofittingIDSOpenBIMBuilding renovationBIMInteroperabilityBPMNWorkflowsDigital constructionRetrofittingIDSOpenBIMGeneral Materials ScienceInstrumentationGeneral EngineeringProcess Chemistry and TechnologyComputer Science ApplicationsFluid Flow and Transfer ProcessesProject IDinfo:eu-repo/grantAgreement/EC/H2020/820773/EU/BIM4Reninfo:eu-repo/grantAgreement/EC/H2020/820773/EU/BIM4RenFunding InfoThis work has been developed within the project BIM4Ren.
