• A HBIM workflow addressing the representation of building construction systems is presented. • It is structured into 5 recursive and flexible phases to adapt to available information/model uses. • Each phase is presented with a methodological insight to help operators in developing the process. • The results of the methodology are applied on The National Archaeological Museum of Naples – MANN. • the test proved its the efficiency while guiding experts the most appropriate course of action. Conservation and valorisation practices of built heritage can greatly benefit from Heritage Building Information Modelling (HBIM) workflows. The use of HBIM as an information management process is not fully established yet, also due to the focus on industrialised architecture typical of the most common BIM tools. Capitalising on the benefits of the BIM process in the field of built heritage requires pursuing a continuous trade-off between geometric accuracy, semantic richness and parametric behaviour. This research aims to present an HBIM workflow that, as compared to other, more specific pipelines, is general in scope to support the planning and implementation of maintenance and conservation activities of built heritage, emphasising the representation of the building construction systems. The workflow is structured in five phases (model planning, data collection, geometric survey, breakdown structure and HBIM modelling), recursive and flexible to influence one another and to adjust to the information available and the development of the work over time. Each phase of the workflow is presented with a general outline and a methodological insight to help operators in developing the HBIM process most suitable for specific cases. The results of the application of this methodology on a complex and massive historical building (The National Archaeological Museum of Naples – MANN) show that the workflow is both versatile and sufficiently flexible to accommodate a heterogeneous range of objectives while guiding experts to select and document the most appropriate course of action.

• Review of the state-of-the-art of BIM and BPS integration and interoperability using a Systematic Literature Review and an expert review of relevant sources of knowledge. • Exploration of strategies for interoperability, main characteristics of information transfer pipelines and related issues reported in the literature. • Review of Research Projects funded by the European Union and Guidelines for BIM and BPS interoperability. • Discussion of the main trends emerged from the review and indication of possible future research developments. The study outlines the state-of-art on interoperability between Building Information Modeling (BIM) and Building Performance Simulation (BPS). First, the paper organises the result of a Systematic Literature Review (SLR) on the topic into three main strategies to achieve interoperability: the scripting to automate the information transfer between BIM and BPS environments, the pipelines supported by current practices, and the MVD and IFC schema extension approach. Software applications, types of files involved, building features, life cycle phases and model geometry considered by the literature along with reported interoperability issues, are also analysed. Secondly, an expert review of grey literature focusing on EU funded projects, guidelines, reports, best practices and key initiatives on the field of BIM to BPS interoperability is presented. The study wraps up by reporting on six major research trends identified by the review and highlighting future developments. The results of the review seem to indicate that effective interoperability can be achieved with the definition of a commonly accepted strategy, integrating shared guidelines for modelling, a better inclusion of energy evaluations through the whole life cycle of a building and the upgrade of software application for the accurate production of information with open format exchange files.

The application of the Building Information Modelling (BIM) process to Built Heritage (HBIM) is a growing practice in processes and activities aimed at the investigation, documentation, and conservation of architectural heritage. However, it still raises some questions, such as the compatibility between the formalisation of information in the BIM model; and what limitations are inherent in current software implementations to establish a connection with external resources. On this basis, this paper aims at reviewing which methods are currently experimented to improve the level of semantic enrichment and to extend the knowledge representation domain offered today by the most common BIM authoring tools in an HBIM process. The analysis distinguishes two approaches that differ in the role played by external databases and the objectives pursued. Conclusions were drawn highlighting common needs for overcoming technical and conceptual limitations imposed by the use of proprietary BIM authoring tools, and differences in application perspectives and effectiveness. [Display omitted] • The application of the BIM process to built heritage (HBIM) is still an open challenge. • It is necessary to overcome both technical and conceptual limitations imposed by BIM tools. • Semantic enrichment of BIM makes use of external databases to link external resources. • It is possible to identify two approaches used for semantic enrichment in HBIM. • Approaches differ in the role played by external databases and the objectives pursued.

The heterogeneity and historical complexity of interventions on built heritage are testified by the constant development of the conservation discipline. The purpose of the research is the development of a digital workflow of parametric modelling for the analysis and conservation of historical buildings, by applying visual programming language (VPL) to support the Heritage Building Information Modelling (HBIM) methodology. VPL represents a tool for explicit parametric modelling that can be used to enhance geometric and information enrichment of HBIM models. The paper describes the integration, within an HBIM-VPL process, of the Index of Masonry Quality, widely used for seismic structural analysis, and its application to a case study in Cornillo Nuovo, a village damaged by the earthquake of Amatrice in 2016. Similar approaches could enhance HBIM modelling to support different knowledge domains associated with built heritage. [ABSTRACT FROM AUTHOR]
