Co-Chair of the Conference
Gabriel Pérez, University of Lleida, Spain

Dr. Gabriel Pérez is Associate Professor and Director of the Department of Industrial and Building Engineering at the University of Lleida. He belongs to the Innovative Technologies for Sustainability research group (IT4S). His academic qualifications are PhD from Polytechnic University of Catalonia (2010), in the PhD program “Research in energy and environment for Architecture” and, Agronomist Engineer from University of Lleida (1995).
His main areas of research refer to the use of green infrastructure in the urban environment as a tool to provide ecosystem services both at building and urban scales.
Specifically, he has studied the use of green roofs and vertical greening systems to improve the thermal and acoustic insulation of buildings, as well as the reduction of the urban head island (UHI) effect and the urban noise in cities. Other developed research topics are related to sustainable construction and the environmental impact of the building sector. Among others, he has conducted research on the use of recycled and sustainable materials instead of the high-impacting ones, and also on the Life Cycle Assessment (LCA) to evaluate the environmental impact of the designed construction solutions.
