In the same way, the concern about the environmental impact of the products used in refurbishment projects is increasing. Based on those two key issues, this paper presents a methodology for the environmental optimization of refurbishment projects with a life cycle perspective. This methodology has been applied to a real case study, consisting on an apartment building built on the 70's in the district of Amara (San Sebastian). As a result, the best refurbishment solution among several options has been identified.4enginfo:eu-repo/semantics/restrictedAccessconference outputEmbodied energyEnergy riiildincrLife cycle assessmentLife cycle zeroRefurbishmentBuilding and ConstructionSDG 7 - Affordable and Clean EnergySDG 12 - Responsible Consumption and ProductionSDG 9 - Industry, Innovation, and Infrastructurehttp://www.scopus.com/inward/record.url?scp=84925234153&partnerID=8YFLogxK
