Abstract
Alpine heritage faces challenges of decay and abandonment. The Interreg SUSMAT research project promotes sustainable transition of the built environment by focusing on the implementation of low-carbon building materials and energy efficient renovation solutions for historical alpine buildings. After the identification of the feasible renovation solutions with the stakeholders involved in the design process (i.e., conservation authorities, local administrations and designers), this study examines the application of LCA for the optimization of the retrofitting design of the Mesnerstadele building in Mölten (Italy). The use of LCA allows to investigate the environmental impacts of the few variable elements of the retrofitting scenario. The results of this study highlight the potential of implementing LCA for reducing the ecological impact when renovating historical alpine buildings.
