LA METODOLOGIA DELLA LIFE CYCLE ASSESSMENT NELLA RIQUALIFICAZIONE ENERGETICA DEGLI EDIFICI STORICI

Abstract

Historic buildings are complex systems of cultural, architectural, and identity value, they need particular attention to ensure that they are preserved, used, and managed over time in a sustainable way. This implies a demand for retrofit solutions able to improve indoor thermal conditions while reducing the use of energy sources and preserving the heritage significance. The presented paper proposes a life-cycle approach to assess energy and environmental assessment specifically devoted to historic building energy retrofit. To this purpose, the presented LCA-based method allows to understand whether the achieved energy benefits could be supported in a life cycle perspective or were overcome by the environmental burdens of the actions. This method could be used to support public policies in the preservation of cultural value buildings, allowing for the assessment of the most effective actions to save energy and to minimize environmental impacts along the whole building life-cycle. As main result, the paper aims at supporting decision makers in selecting energy retrofit solutions, tailored to solve the conflict between conservation and energy performance requirements
