The University of Trieste hosted the presentation of the results of 3FiRES – Research on BIPV Photovoltaic Façades for Fire Spread Mechanisms, Structural Failures and Resilience Improvement Methodologies, a project carried out by the University of Trieste in partnership with the University of Science and Technology of China (USTC).

3FiRES is one of ten major projects selected under the Executive Programme of Scientific and Technological Cooperation between Italy and China, a bilateral initiative co‑funded by MAECI and MOST.

The two‑year collaboration, with total funding of €500,000, was coordinated by Prof. Chiara Bedon (UniTS) and Prof. Yu Wang (USTC).

Within the thematic area “Green Energy and related research”, 3FiRES investigated—through analytical, numerical and experimental methods—the behaviour of Building‑Integrated Photovoltaic (BIPV) façades subjected to extreme and accidental actions, in particular fire. These innovative electricity‑generating systems make a significant contribution to the sustainability of green buildings while being required to guarantee appropriate structural and architectural performance even under limiting conditions.

At the University of Trieste, the study brought together a multidisciplinary team from the Department of Engineering and Architecture (DIA), combining civil, electrical and architectural engineering expertise, with the involvement of Alessandro Massi Pavan, Vanni Lughi, Luca Cozzarini, Marco Fasan, and Adriano Venudo, alongside several early‑career researchers.

The activities included extensive experimental campaigns conducted in the DIA laboratories in Trieste and—above all—at the State Key Laboratory of Fire Science (USTC) in Hefei and the Fire Laboratory of the Slovenian National Building and Civil Engineering Institute (ZAG) in Logatec. The datasets enabled the development and refinement of finite‑element modelling strategies.

The results have been disseminated through numerous publications in leading international journals and presentations at major conferences, as well as two volumes published by EUT – Trieste University Press. A key outcome is a patent filed with the China National Intellectual Property Administration (CNIPA) and granted in April 2025.

The patent concerns the prototyping of a device and experimental method for the fire testing of integrated photovoltaic glass panels, allowing multiple test parameters to be varied. Intellectual property is held by the following researchers: Prof. Yu Wang, Dr Haonan Chen, Dr Dezhi Ran, Dr Wei Chu, and Prof. Chiara Bedon.

Initial applications and results underlying the patent have been published in the International Journal of Thermal Sciences.
