A factor relevant for some European regions is their ongoing depopulation. In these regions, building energy retrofitting presents additional challenges to those in urban areas, such as over-dimensioned public buildings and low occupancy levels. This work analyses these challenges in the province of Teruel (Spain), one of the regions with the highest depopulation levels in Spain. To this end, a methodology has been developed to assess the effect of depopulation on the cost of upgrading public buildings to improve their energy efficiency. The results show that the investment required per inhabitant for building retrofitting is approximately four times as high in depopulated areas as in urban areas. Furthermore, the low occupancy levels of public buildings can triple the payback time of some energy efficiency measures. To overcome these barriers, in addition to specific policies for depopulated areas, energy planning is essential. An adequate action plan, combining the implementation of energy efficiency measures and the integration of renewable energies in buildings, is the most effective tool to improve the sustainability of public buildings circumventing the barriers created by depopulation. info:eu-repo/grantAgreement/ES/DGA-FEDER/T32-20R info:eu-repo/grantAgreement/EUR/INTERREG MED 959-1MED15_2.1_M2_205 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 7.1 2023 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 21 / 91 = 0.231 2023 Q1 T1 ENERGY & FUELS 41 / 171 = 0.24 2023 Q1 T1 1.566 2023 Renewable Energy, Sustainability and the Environment 2023 Q1 Energy Engineering and Power Technology 2023 Q1 12.7 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Chordá, Ramón Universidad de Zaragoza Gómez, Antonio Universidad de Zaragoza (orcid)0000-0001-6019-5186 Fueyo, Norberto Universidad de Zaragoza (orcid)0000-0001-6205-5160 5001 600 Universidad de Zaragoza Dpto.
