Abstract: The combination of structural and thermal efficiency is a new frontier in civil engineering. Indeed, the retrofitting strategies should optimise costs and technical solutions from these two points of view. If a technical solution is able to provide an improvement of both structural and energetic behaviour, then the utility of the intervention can better justify the economic investment. In this paper a mesoscale approach for integrated interventions applied on masonry façades is proposed. The structural performance of the façade is evaluated by considering base shear and ductility of the structural element through nonlinear static analyses. Moreover, the thermal indicator, that is the thermal transmittance, is computed with a simplified approach in terms of equivalent wall, taking into account the role of windows and doors of the façade. Economic and ecological iso-cost curves are obtained to tune the interventions conceived for a real case study, analysing the benefit offered by different retrofitting solutions.
