Abstract

The residential sector is one of the most energy-intensive sectors of a country and energy efficiency in buildings is crucial in order to achieve the goal of reducing by 20% the EU energy consumption by 2020. The regulatory framework, both at European and National level, emphasizes more and more this need, requiring performance limits increasingly stringent. Within this context, the analysis and the optimization of the energetic and environmental performance of existing buildings becomes a key issue. This paper aims to present how the Life Cycle Assessment (LCA) methodology, that allows the measurement of the environmental impact of products and services across all life cycle stages, could be used to achieve this goal. The results of various case studies are shown and a methodological approach is proposed as a guideline for LCA of existing buildings, demonstrating its real potential in this applications.
