Benat Arregi is industry-based architect and hygrothermal risk assessor based in Bilbao, Spain. He lectures part time on the online DT9773 MSc Building Performance (Energy Efficiency in Design) programme.
Beñat works as a researcher within the Sustainable Construction Division of Tecnalia, and his expertise lies in optimising the thermal and hygric performance of energy-efficient building envelopes. He holds a degree in Architecture from the University of the Basque Country (2007). From 2009 to 2016 he was a core member of Building Life Consultancy in Dublin, where he specialised in thermal bridge modelling and hygrothermal numerical simulation. In 2016 he joined Tecnalia in Bilbao, where he is primarily involved in the development of energy-efficient systems and products for building envelopes. Together with Joseph Little, he created and delivered courses on energy-efficient retrofit and building fabric design for the RIAI (2010-2015), and has also delivered training in thermal modelling, hygrothermal numerical simulation, and data analysis and visualization. Since 2016 he is a part time lecturer in hygrothermal risk assessment at DIT. During the last ten years, he has published more than 20 scientific papers and has taken part in research and innovation programmes of regional and European scope. His current research interests include the design of full-scale experiments and the development of dynamic models for describing the ABIS (as built and in service) performance of building envelopes.
