HBIM-Driven Design for Disassembly: Lightweight, Flexible and Reversible Photovoltaic Canopy for Historic Buildings
摘要
This study focuses on demonstrating the application of a collaborative and interoperable workflow using Heritage Building Information Modelling (HBIM) tools to integrate removable photovoltaic (PV) systems into historic buildings. The workflow emphasizes design for disassembly, allowing for easy removal of PV installations to preserve the historical integrity of the structure. It combines architectural restoration principles with parametric modeling to create an efficient value chain among key stakeholders, such as architects, structural and electrical engineers, PV consultants, Heritage and Public Authorities, and PV manufacturers. The approach is applied to the design of a lightweight and removable PV canopy for a historic building, optimizing the intervention to be both functional and reversible. The assessment of heritage-compatible PV solutions follows a multi-criteria framework, evaluating factors such as aesthetic impact, technological compatibility, energy efficiency, cost, and environmental considerations. Customized PV components are developed in collaboration with manufacturers to ensure precision in geometric, material, and technological specifications, as well as electrical properties and cost. This HBIM-PV approach provides a proactive tool for evaluating interventions, facilitating cost-effective adjustments, and ensuring heritage preservation through reversible design solutions.
