Abstract
Today, a building is not just a “body” or a “machine” as defined by modern architecture, but rather an immaterial entity immersed in a digital world where not only its components but also the information associated with it are accounted for. In recent decades, building information modelling (BIM) has made it possible to move from 2D CAD drawings to 3D models capable of supporting different processes and interacting with different disciplines in the AEC industry for storing, documenting and sharing heterogeneous content. It has thus become possible to direct these techniques towards built heritage to investigate new forms of communication and share heritage building information modelling (HBIM) models. This research investigates this evolution in both generative terms (scan-to-BIM process) and cultural and historical terms in order to orient BIM uses towards novel forms of interactivity and immersion between users and models. The author proposes the use of a digital process and the development of VR and AR environments based on a visual programming language (VPL) to improve access to a deeper knowledge of HBIM models and the artefacts and information contained therein.

The Digital Era in Cultural HeritageThe digital era we live in is characterised by a continuous evolution of knowledge, working methods and updating processes that we apply in our daily work
This study investigates and shows the pros and cons of heritage building information modelling (HBIM) through several case studies conducted in the field in the last 10 years and how, thanks to information technology (IT) developments, visual programming language (VPL) and models designed for interoperability, it is possible to increase the level of human–digital model interaction
The work flows that led to the creation of HBIM models are analysed to highlight the limits of interoperability, interactivity and immersion
Summary
The Digital Era in Cultural HeritageThe digital era we live in is characterised by a continuous evolution of knowledge, working methods and updating processes that we apply in our daily work. World-renowned skills and methods have been developed in Europe based on new technologies to preserve, manage and leverage value from cultural heritage (CH) [4]. Recent developments in computer graphics are re-engineering the construction sector and facilitating the management of existing buildings and complex structures [5,6,7]. Intangible heritage includes different values related to representations, practices, historical memories, knowledge and skills that communities construct, use and transmit from a complex and varied historical evolution [10]. Digital heritage (DH) includes a considerable amount of information obtained with different types of new tools and methods, as identified in the Strategic Research Agenda (SRA) for JPI-CH Using the JPI CH Vision Document as a starting point, further input was requested from a wide range of stakeholders across Europe reflecting the three key facets of cultural heritage: tangible, intangible and digital. http://www.jpi-culturalheritage.eu/wp-content/uploads/SRA-20
