Arianna Fonsati

Researcher at the Division of Sustainable Buildings.

The research focuses on advancing digitalisation in the built environment, with a strong emphasis on BIM-based workflows, digital twins, and data-driven decision support for sustainable buildings.

Early work at KTH (2022–2023) explored how BIM and related digital technologies can improve education, infrastructure modelling, and interdisciplinary integration, including GeoBIM approaches and information modelling for bridges and precast systems. From 2023 onward, her studies increasingly address interoperability and information management challenges, particularly the need to improve data exchange across design, construction, and operation and management domains. In 2024–2025, her work shifts toward advanced digital twin frameworks and circular construction, highlighting how structured data, AI-enabled methods, and digital inventories can support sustainability and resource efficiency in the built environment. Most recently (2025–2026), her research consolidates these themes by developing openBIM and Information Delivery Specification (IDS) approaches to improve validation, the reuse of building components, and the reliable availability of data for circular and energy-aware building processes.

She also participates in the IEA EBC Annex 91 initiative and several nationally and internationally funded research projects, and coordinates the oBtoB project, funded by Energimyndigheten, which focuses on advancing openBIM-to-building energy modelling workflows.
