Digitisation of the Existing Built Heritage for Reuse

Architecture is a constantly evolving process, characterized by layering and transformations that redefine its meaning and function over time. Reuse and redevelopment are key strategies for building heritage conservation and environmental sustainability, in line with the goals of the UN 2030 Agenda. Adaptation of existing buildings makes it possible to reduce land consumption and pollutant emissions while preserving the historical identity of places. Architectural rehabilitation addresses three main forms of obsolescence: technological, functional, and image. Through a careful process of analysis, which includes assessment of residual performance and stratigraphic reading of the building, targeted interventions compatible with the context can be identified. The integration of digital methodologies and advanced modeling tools makes it possible to optimize design solutions, improving energy efficiency and space quality. The case study of the Pavia Idroscalo (seaplane base) exemplifies the challenges and opportunities of architectural rehabilitation. Built in the 1920s to support Italy's nascent civil aviation, the building has undergone transformations and is now in a state of disrepair. The design proposal aims to restore value to the building through a multifunctional approach that promotes public enjoyment, connection with the city and inclusion in a network of enhancement of the river territory. This case study, part of a Msc thesis research project, highlights how knowledge of the building, its history and its context are key elements for a sustainable intervention, capable of combining preservation and innovation, and of restoring new life to disused spaces through integrated recovery strategies, starting with digital modeling methodologies to support decision-making. Modeling and simulation tools make it possible to analyse residual performance and optimize interventions, ensuring a balance between conservation and innovation.
