Effects of retrofit in public building schools provided by urban green infrastructure: a case study in southern Italy

Post-pandemic financial efforts have been set by the EU Commission and European governments regarding the renovation of European building heritage. Building schools will be object of interest to be transformed in more resilient buildings through improvement building energy performance which guarantee environmental sustainability; the renovation of building school heritage in Italy aims to ease new students' learning process through adaptation and implementation of new didactic methodologies. In this study is described a multi-scale methodology adopted to evaluate both at urban scale and building scale different scenarios that adopt green infrastructure as vegetation and building integrated greenery systems. The greenery system was implemented on microarchitectures that represent a temporary solution in case of health emergencies. The results of simulations at the building scale showed a significative reduction in terms of temperature during summer months, due to the positive effects of evapotranspiration and the reduction of albedo shortwave.
