The European Union is pushing towards the adoption of energy production systems from Renewable En- ergy Sources, in both new and existing buildings.

This research aims to define a collaborative and interoperable workflow that utilizes Heritage Building Information Modelling (HBIM) tools to facilitate the integration of advanced and cus- tomized PV technologies and components in historical buildings refurbishment operations. The workflow combines architectural refurbishment practices with parametric rendering and a best-choice protocol to establish an efficient stakeholder value-chain for a collaborative approach. The methodology includes the following four steps: (i) historical research and on-site survey; (ii) HBIM model construction; (iii) selec- tion of PV interventions and technologies; (iv) modelling of the selected PV components and integration in the HBIM model. The study also demonstrates the output of applying this workflow to a real histor- ical building through a case study. Heritage-compatible building integrated PV (BIPV) interventions are evaluated following a multi-level risk-benefits scheme that considers factors such as aesthetic impact, technological compatibility, theoretical energy performances, economic costs, and environmental issues. Subsequently, selected interventions and advanced customized BIPV elements are modelled in BIM en- vironment. The study highlights the positive implications of this HBIM-based workflow in various as- pects, including decision-making (e.g., promoting collaboration and interoperability), modelling (e.g., pre- emptive evaluation and reduction of impacts, PV component customization, and optimization), and data and process management (e.g., creating an all-in-one model for future assessments and operations).

Abstract
The European Union is pushing towards the adoption of energy production systems from Renewable En- ergy Sources, in both new and existing buildings. However, integrating photovoltaic (PV) applications into historical heritage context remain challenging due to a number of different barriers, primarily related to social acceptability. This research aims to define a collaborative and interoperable workflow that utilizes Heritage Building Information Modelling (HBIM) tools to facilitate the integration of advanced and cus- tomized PV technologies and components in historical buildings refurbishment operations. The workflow combines architectural refurbishment practices with parametric rendering and a best-choice protocol to establish an efficient stakeholder value-chain for a collaborative approach. The methodology includes the following four steps: (i) historical research and on-site survey; (ii) HBIM model construction; (iii) selec- tion of PV interventions and technologies; (iv) modelling of the selected PV components and integration in the HBIM model. The study also demonstrates the output of applying this workflow to a real histor- ical building through a case study. Heritage-compatible building integrated PV (BIPV) interventions are evaluated following a multi-level risk-benefits scheme that considers factors such as aesthetic impact, technological compatibility, theoretical energy performances, economic costs, and environmental issues. Subsequently, selected interventions and advanced customized BIPV elements are modelled in BIM en- vironment. The study highlights the positive implications of this HBIM-based workflow in various as- pects, including decision-making (e.g., promoting collaboration and interoperability), modelling (e.g., pre- emptive evaluation and reduction of impacts, PV component customization, and optimization), and data and process management (e.g., creating an all-in-one model for future assessments and operations).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
