Moving from the study of international experiences in the field of high schools’ outdoor spaces renovation and then focusing on the case study of the city Turin, the research presented on this documents aims at identifying design strategies for the sustainable regeneration of the city’s high school buildings infrastructure. The research will focus on outdoor spaces (open spaces, courts, building envelop, accessibility...), identifying recurring typologies by measuring the territorial and architectural characteristics of the high schools’ infrastructures. This analysis is followed by the selection of three representative high schools examples in Turin, suitable for hosting potentials of transformation at the urban and architectural scales, proposing tools and devices that could allow the reproducibility of the interventions in similar schools, in Turin and other contexts.
