Sustainability is an inherent urban and architectural problem. It is simultaneously characterized by many different dimensions, pursuing heterogeneous and often conflicting objectives. To help address these complexities in a structured way, this paper illustrates an integrated assessment framework to tackle social sustainability, in order to support the decision-making process towards sustainable architecture. This integrated decision support framework was applied to a case study concerning a new cultural centre at the Politecnico di Torino in Italy. The aim of this paper is to propose a decision support methodological framework for the analysis, graphical visualization and evaluation of social sustainability of architectural projects. It combines three methods: first, Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis, to get a guided understanding of the project and detect the best design strategies; second, the Stakeholder Analysis (SA), to develop a strategic view of the actors involved; third, the Social Return of the Investment (SROI) as a methodological tool for social impact assessment. This framework, presented through the discussion of some project solutions, helps us to analyse the architectural material effect of social sustainability and answer the question: Are we investing properly and creating spaces sufficiently functional to build better conditions for our community and our city?
In this paper we deal with an urban and territorial planning problem by applying the Non Additive Robust Ordinal Regression (NAROR). NAROR is a recent extension of the Robust Ordinal Regression family of Multiple Criteria Decision Aiding methods to the Choquet integral preference model which permits to represent interaction between considered criteria through the use of a set of non-additive weights called capacity or fuzzy measure. The use of NAROR permits the Decision Maker (DM) to give preference information in terms of preferences between pairs of alternatives with which she is familiar, and relative importance and interaction of considered criteria. The basic idea of NAROR is to consider the whole set of capacities that are compatible with the preference information given by the DM. In fact, the recommendation supplied by NAROR is expressed in terms of necessary preferences, in case an alternative is preferred to another for all compatible capacities, and of possible preferences, in case an alternative is preferred to another for at least one compatible capacity.In the considered case study, several sites for the location of a landfill are analyzed and compared through the use of the NAROR on the basis of different criteria, such as presence of population, hydrogeological risk, interferences on transport infrastructures and economic cost. This paper is the first application of NAROR to a real-world problem, even if not already with real DMs, but with a panel of experts simulating the decision process.
The COVID-19 pandemic has profoundly affected the relationship between people’s behaviors and residential spaces, bringing to public and academic attention, on the one hand, the exacerbation of pre-existing problems and, on the other, the potential of spaces, such as communal gardens and apartment-block terraces, to become important resources of sociability or privacy. Overall, this raises the question of how to assess the responsiveness of the existing residential stock to needs that transcend the traditional concept of housing adequacy—e.g., the need for adaptable, open, and livable spaces. This research moves from the assumption that underused spaces in residential neighborhoods represent a crucial asset for creating new economic and social values through architectural and urban projects. Consequently, moving from an in-depth observation of a selection of public housing buildings in Turin as a paradigmatic case study, the aim is to explore the potential for the adaptive reuse of residential spaces at different scales—from the apartment to the neighborhoods—highlighting the implications for design. In doing so, the paper puts forward a methodological approach, which widens the way housing adequacy is normally assessed, by focusing on the possibility of transformation of often neglected spatial resources.
