The number and diversity of the EU buildings increases the complexity of a large-scale modernisation effort based on combined seismic and energy renovation.
A simplified analysis to identify EU building typologies that could benefit from combined seismic and energy renovation is carried out, with a focus on the Italian building stock. This analysis facilitates the selection of suitable renovation strategies and technologies, useful for practitioners and local authorities.
Technologies for seismic and energy renovation are explored to assess their applicability mainly in terms of compatibility, cost and disruption time, as well as to ease the decision-making process in the preliminary phase of renovation.
Technologies for seismic renovation are reviewed and classified both qualitatively by life cycle thinking-based criteria, and quantitatively through a cost analysis to define average cost ranges of common renovation technologies for masonry and reinforced concrete buildings.
Technologies for energy renovation are reviewed, qualitatively classified by a set of indicators, and ranked using a multi-criteria decision-making analysis.
