Dr. Gabriel Pérez is an Associate Professor and Researcher at the Department of Industrial and Building Engineering, University of Lleida. He holds a PhD from the Polytechnic University of Catalonia (2010), where he participated in the “Research in Energy and Environment for Architecture” PhD program. He also obtained an agronomist engineering degree from the University of Lleida (1995) and an agricultural engineering degree from the Polytechnic University of Catalonia (1993). Dr. Pérez is a member of the Innovative Technologies for Sustainability (IT4S) research group (https://it4s.cat—2021 SGR 00512). His primary research focus has been the implementation of green infrastructure in urban environments, particularly green roofs and facades, to provide ecosystem services at both building and urban scales. He has extensively studied the integration of green roofs and vertical greening systems on building envelopes to enhance thermal and acoustic insulation, mitigate the urban heat island (UHI) effect, and reduce urban noise. Additionally, Dr. Pérez's research encompasses sustainable construction and the environmental impact of the building sector. He has investigated the use of recycled and sustainable materials as alternatives to high-impact conventional ones. His work also includes Life Cycle Assessment (LCA) to evaluate the environmental impact of various construction solutions.
