He is a Chartered Architectural Technologist and Building Engineer. He has been General Chair for the Sustainability in Energy and Buildings International Conference in 2014, 2017, and since 2019 to date and Chair of the Sustainable and Resilient Buildings General Track since 2016. His research is conducted in collaboration with industry to optimise the design, offsite manufacturing, construction, and operation of existing and new buildings to maximise their performance and user comfort and quality of life, yet reduce embodied and operational carbon emissions. He has authored, co-authored, and co-edited 196 peer-reviewed articles, papers, conference proceedings, and book volumes. His current research with industry includes innovations in offsite manufactured buildings systems for net-zero-carbon dwellings; benchmarking organisational carbon emissions for decarbonisation; and measuring retrofit pathways to net-zero carbon for existing dwellings' fabric and renewable energy systems.

Prof. Antonio Gagliano has been a professor at the University of Catania, where he teaches Technical Physics and Environmental Control. Techniques. Antonio's research focuses on building energy efficiency, optimizing renewable energy systems, and integrating photovoltaics and photothermal energy plants within the built environment. He has authored and co-authored 200 peer-reviewed papers. Currently, he serves as a member of the editorial board for several international journals (10) and one national journal.
