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?

The paper shows how Multiple Criteria Decision Aiding (MCDA) tools can support the analyses of six hypotheses of adaptive reuse of an iconic historical building in Turin, Italy (called Stock Exchange) to identify the preferred alternative. In the last two years, the debate around the requalification of the building has been huge for several reasons: it is perceived as a "monument" by citizens; it shows architectural and typological values nationally recognized; it involves public and private interests. In this context, we tested the applicability of a recently proposed multicriteria decision making methodology to architecture field. This decision support approach is a conjunction of four MCDA methods, namely: Multiple Criteria Hierarchy Process (MCHP), permitting to consider structural relationships between criteria; ELECTRE III, considering three types of interaction effects between criteria (strengthening, weakening and antagonistic effects); the imprecise SRF method, supplying an easily understandable approach to collect information from the DM; and Stochastic Multicriteria Acceptability Analysis (SMAA), providing robust recommendation, in terms of rankings and relations of preference, indifference and incomparability between project alternatives, at each level of the hierarchy. We propose a modification of the SRF methodology, called SFR-II, to increase the reliability of the decision aid procedure, which could constitute a significant advance for the same SRF method.

Our cities represent the crucial nodes of intervention to improve living conditions and promote sustainability.Therefore, the current pandemic, combined with the climate emergency, translates into an urban emergency.In light of the devastating effects of Covid-19 and the rethinking of the concept of sustainability, the goal of developing inclusive, safe, resilient and sustainable cities and human settlements pursued by theSustainable Development Goal 11 may now require re vision in terms of the indicators used for its monitoring. Indicators are crucial since they help to make sustainable development visible and transparent, enable comparison, build and harmonize databases and provide information relevant to decision-making processes and urban and territorial policies by facilitating communication across arenas. The aim of this paper is to provide a picture of the indicators currently used to monitor SDG11, to present a series of critical reviews of them in light of the Covid-19emergency, and to suggest the introduction of some new indicators, thus opening a scientific debate on the topic.

The concept of sustainable development is closely related to that of sustainability assessment, as it implies a process of evaluation of progress made over time. In this context, indicators present themselves as a key and fundamental element for measuring and evaluating the specific issues that compose the different phenomena to be monitored. Indeed, they constitute the tool that can provide qualitative or quantitative data and information needed to identify the performance, progress, and weaknesses of plans, projects, and policies. In this context, the paper investigates the potential differences that the indicator can take in the differing purposes of measurement and evaluation in the context of urban sustainable development. A literature review is therefore conducted to gather and systematize knowledge so that it can be useful for reflections on sustainable urban assessment. The paper reports the results of the analysis concerning the context of measurement and evaluation, highlighting the differences or similarities from a conceptual and operational point of view.

This paper explores the enhancement of adaptive reuse (AR) of buildings through the lens of the sustainability protocols within the context of circular economy (CE) in Italy. Cities and the built environment can play a key role in the transition to a CE, especially considering the documented negative global impact due to resource consumption and waste generation. This is recognised among the principles of circularity defined by the European Commission towards a general strategy for a sustainable built environment, which encourages initiatives of building reuse and land consumption reduction. It has been proven that the AR of vacant buildings can bring environmental, social, and economic benefits towards an urban strategy based on CE principles by generating useful values to support innovative development dynamics. In this perspective, the sustainability protocols can be identified as useful tools to pursue strategies for spreading the culture of sustainable build environment. Considering the huge vacant Italian architectural heritage, this paper aims to analyze how the most widely used sustainability protocols in the Italian context currently address the enhancement of the reuse of buildings, to improve environmental, social, and economic quality in the built environment. We discuss the results highlighting how and which sustainability protocols better intercept these issues, providing grounds for future development.
