The design aims to meet the requirements (water, electricity, heat and cold air) from Renewable Energy Sources (RESs), in particular by selecting photovoltaic and photovoltaic-thermal panels, thermoelectric generators, and biomass as auxiliaries. Electricity is available from the grid, and no electrical storage is planned. Water and cooling may be produced by alternative technologies that configure the polygeneration alternatives. The case study is in Valencia, a coastal Mediterranean city in Spain. The Design Builder Clima estimated demand calculations, and the system performance was modeled in TRNSYS. Desalination was linked by using EES models. Results show that the suggested schemes offer substantial energy and CO2 savings. The innovative life-cycle analysis applied further enhances the cumulative CO2 savings across the four configurations if the impact of the installations is compared with the conventional external supply. The electric option (combining heat pump and reverse osmosis for cooling and desalination) emerged as the most appealing solution due to its reliability, lower investment cost, and environmental impact. info:eu-repo/grantAgreement/ES/MICIU-AEI-FEDER/RTI2018-098868-A-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 3.3 2024 ENVIRONMENTAL SCIENCES 178 / 376 = 0.473 2024 Q2 T2 ENVIRONMENTAL STUDIES 80 / 193 = 0.415 2024 Q2 T2 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 67 / 103 = 0.65 2024 Q3 T2 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 67 / 103 = 0.65 2024 Q3 T2 0.688 2024 Geography, Planning and Development 2024 Q1 Energy Engineering and Power Technology 2024 Q2 Environmental Science (miscellaneous) 2024 Q2 Renewable Energy, Sustainability and the Environment 2024 Q2 Hardware and Architecture 2024 Q2 Management, Monitoring, Policy and Law 2024 Q2 Computer Networks and Communications 2024 Q2 7.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martínez-Gracia, Amaya Universidad de Zaragoza (orcid)0000-0003-1238-8746 Zabalza, Ignacio Universidad de Zaragoza (orcid)0000-0001-6183-0831 Usón, Sergio Universidad de Zaragoza (orcid)0000-0002-9279-1959 5004 590 Universidad de Zaragoza Dpto.
