Innovative methods for a sustainable retrofit of the existing building stock. A cross-path from social housing to the listed heritage

Three correlated researches try to give operative answers to the problem of defining procedures and tools for a correct survey and retrofit actions for the existing building stock. Starting from a first research on social housing energy retrofit, a fast audit protocol and different intervention scenarios have been defined, with the ultimate purpose of supporting the energy transformation of older urban aggregates; this cluster includes single buildings with high historical values, which necessarily need a deeper diagnosis with a future perspective of a wider promotion and evaluation of environmental sustainability issues.
