Professor Fiocchi’s interest and research are concerned with high performance energy efficient buildings with special emphasis on the building envelope and mechanical systems of both residential and commercial structures. He has led the initiative to establish the UMass DesignBuild program which produces a low carbon net positive Accessory Dwelling Unit (ADU) each year which is donated to the city of Holyoke where it contributes to addressing the affordable housing crisis in an underserved community. His experience in construction, coupled with the imminent threat of climate change, provided the impetus for these efforts. Modernist architecture and its subset Brutalism, as it relates to the above, has been a continued focus of his work.
