Prioritization of Italian Residential Buildings for Seismic and Energy Efficiency Performance Upgrading

This paper proposes an integrated framework, specifically calibrated and demonstrated for the Italian residential building stock, applicable to any other region or country, for regional-based prioritization of residential buildings for seismic and energy efficiency performance upgrading. The framework encompasses single and multi-sectoral indicators, estimated according to state-of-the-art engineering-based research, providing different prioritization patterns at national scale. The most recent building fragility models for Italy are selected and combined through a logic tree strategy. The space heating energy consumption and CO2 emissions are directly taken from a collection of all the Energy Performance Certificates (APE) of Italian buildings and building units, while national and European indices are used to account for socioeconomic aspects. The proposed framework and the prioritization patterns obtained in this work can support relevant stakeholders to foresee economic support and strategic financial planning for seismic strengthening and energy renovation interventions on existing buildings, including socioeconomic features, and favor funding in regions of higher needs.
