A multicriteria decision-making technique implemented in a geographical information system (GIS) environment was used to extract suitable rooftop areas. To implement this method, the slope (tilt), aspect (azimuth), shading, and solar radiation of the rooftops were calculated using LiDAR (Light Detection and Ranging) data and building footprints. The potential of FEW system implementation was analysed at the building and morphology levels. The results showed several differences between residential and non-residential urban morphologies. Industrial areas contained the highest productivity for FEW systems. The production was 2.51 kg of tomatoes/m2, 48 kWh of photovoltaic energy/m2, and 0.16 l of rainwater/m2. Regarding the residential urban morphologies, the more compact tents resulted in better performance. Among the FEW systems, although water could best benefit from the features of the entire roof surface, the best production results were achieved by energy. The food system is less efficient in the built environment since it requires flat roofs. The methodology presented can be applied in any city, and it is considered optimal in the European context for the development of self-production strategies for urban environments. info:eu-repo/grantAgreement/ES/UZ/UZ2020-TEC-07 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 9.8 2022 ENVIRONMENTAL SCIENCES 26 / 275 = 0.095 2022 Q1 T1 1.946 2022 Environmental Chemistry 2022 Q1 Waste Management and Disposal 2022 Q1 Pollution 2022 Q1 Environmental Engineering 2022 Q1 16.8 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion García-Pérez, Sergio Universidad de Zaragoza (orcid)0000-0003-3269-023X Guillén-Lambea, Silvia Universidad de Zaragoza (orcid)0000-0001-6288-2780 Monzón-Chavarrías, Marta Universidad de Zaragoza (orcid)0000-0002-0492-3625 Sierra-Pérez, Jorge Universidad de Zaragoza (orcid)0000-0002-7660-3508 5015 110 Universidad de Zaragoza Dpto.
