The reduction of primary energy consumption and emissions of carbon dioxide are two key objectives of international policies, as demonstrated by the stricter international standards about the buildings’ energy efficiency promoted worldwide. The building sector is considered one of the most important strategic sectors for achieving these goals so, energy policies at global level have been promoting strategies for the regulation of its energy efficiency through the design of sustainable buildings. This paper aims to demonstrate, through a case study, the effectiveness and complementarity of different strategies both at urban and building scales for the improvement of indoor and outdoor users’ comfort and of the energy efficiency of existing buildings. These strategies include the optimization of land consumption and the regeneration of urban context too. Cappuccinelli Social Housing district in Trapani has been analysed in order to evaluate its actual state and to promote actions aimed to improve the climatic benefit of its inhabitants. This district is currently characterized by widespread conditions of urban and social decay and the first objective of the study has been to rehabilitate the urban context. The redesign of the urban context have been developed with the support of data collected through simulations carried out for understanding the local microclimate and with the aim to satisfy the needs related to the environmental sustainability through the use of vegetation, in the attempt to reduce, in the meantime, the cost impact of buildings’ retrofit actions. Some buildings of the social housing complex have been, also, analyzed in detail and retrofit strategies for the improvement of inhabitants’ indoor comfort have been proposed. The paper aims to demonstrate how the environmental sustainability issues and the reduction of the buildings energy consumption require a careful study of social, economic and environmental aspects both at micro-urban and building scales and how the buildings’ retrofit can contribute to the reduction of soil consumption and be fundamental for the achievement of global results for the protection of environmental resources, the development of lands and citizens in a view of circular economy.
