This work proposes a methodology to estimate the level of energy self-sufficiency in urban areas, particularly in a district of the city of Zaragoza (Spain). First, the Energy Self-Sufficiency Urban Module concept (ESSUM) is defined, then the self-sufficiency capacity of the city or district is determined using Geographical Information Systems (GIS), Light Detection and Ranging (LiDAR) point clouds and cadastral data. Secondly, the environmental implications of the implementation of these modules in the rooftops of the city using the LCA methodology are calculated. The results obtained show that total self-sufficiency of Domestic Hot Water (DHW) can be achieved using 21 % of available rooftop area, meanwhile the rest of rooftop area, dedicated to photovoltaic (PV), can reach 20 % of electricity self-sufficiency, supposing a final balance of a reduction in CO2 emissions of 12,695.4 t CO2eq/y and energy savings of 372,468.5 GJ/y. This corresponds to a scenario where full self-sufficiency of DHW was prioritized, with the remaining roof area dedicated to PV installation. In addition, other scenarios have been analyzed, such as the implementation of the energy systems separately. 000126332 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/RYC2021-034265-I$$9info:eu-repo/grantAgreement/ES/UZ/UZ2020-TEC-07 000126332 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000126332 590__ $$a8.2$$b2023 000126332 592__ $$a1.998$$b2023 000126332 591__ $$aENVIRONMENTAL SCIENCES$$b31 / 358 = 0.087$$c2023$$dQ1$$eT1 000126332 593__ $$aEnvironmental Chemistry$$c2023$$dQ1 000126332 593__ $$aWaste Management and Disposal$$c2023$$dQ1 000126332 593__ $$aPollution$$c2023$$dQ1 000126332 593__ $$aEnvironmental Engineering$$c2023$$dQ1 000126332 594__ $$a17.6$$b2023 000126332 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126332 700__ $$0(orcid)0000-0002-7660-3508$$aSierra-Pérez, J.$$uUniversidad de Zaragoza 000126332 700__ $$0(orcid)0000-0002-1672-4965$$aGarcía-Pérez, S.$$uUniversidad de Zaragoza 000126332 700__ $$0(orcid)0000-0001-6288-2780$$aMontealegre, A.
