Addressing social sustainability in urban regeneration processes. An application of the social multi-criteria evaluation

The concept of sustainability is widely seen as fundamental to set up urban and territorial transformations. Sustainable development is a multidimensional and multi-perspective process that deals with the environmental, economic, and social dimensions, with the aim to find a balance among these. Despite this growing attention to sustainability the social perspective has been the less explored of these dimensions and only recently it is receiving consideration due the Sustainable Development Goals (SDGs) that aim at creating sustainable and inclusive cities and communities. In the SDGs, specific attention is focused on the improvement of the quality of life of inhabitants through specific actions dedicated to the valorization of cultural resources, to the protection of the environment, and also to promote the involvement of the local communities in setting policies and programs. The final objective is defining projects based on the social needs shared by the communities. This paper aims at exploring the social sustainability related to urban regeneration processes with particular attention to social cohesion and community engagement. Six different urban regeneration strategies, developed for the regeneration of an urban area located in Northern Italy and based on social housing interventions, have been evaluated in accordance with their social impacts on the stakeholders involved. The paper proposes a multi-methodological approach based on the combination of the stakeholder analysis with the NAIADE (Novel Approach to Imprecise Assessment and Decision Environments) methodology, a particular type of Social Multi-Criteria Evaluation. The stakeholder analysis has been applied to identify the actors to involve in the evaluation, whereas the NAIADE methodology has been implemented for the selection of the most preferable strategy. This method allowed the assessment of the different strategies through the comparison and the mediation between the technical and the social rankings, thus considering the stakeholder preferences in the final evaluation. The final result is coherent with the initial purpose and it demonstrates that the inclusion of the stakeholder is fundamental for the achievement of a consensus solution

A mixed methods approach for the integration of urban design and economic evaluation: industrial heritage and urban regeneration in China

This paper presents the early results of a study aimed at experimenting an innovative approach to the design and the evaluation of complex urban transformation processes, based on the combined use of different design strategies and tools. The purpose of the paper is to illustrate, by means of a case study, a multi-level decision aiding process, able to support strategic urban design, with specific reference to regeneration processes for abandoned industrial sites in urban areas. The case study presented in the paper concerns different alternative proposals for the requalification of the former Shougang/Er-Tong mechanical factory in Beijing, China. The choice of a Chinese case study as a field test for an experimentation about mixed methods research approaches in the domain of urban transformation is related to the peculiar emerging conditions of that context, in which huge economic potentials are speeding up the transformation but a substantial lack of cultural and methodological instruments to manage a so fast modification exists. During the design process, three methods in particular have been combined according to a multi-phase design: (i) Stakeholders Analysis, (ii) Multicriteria Analysis, and (iii) Discounted Cash Flow Analysis. Each one of them has been applied in parallel to the evolution of the different design scenarios. The results of the performed study show that mixed methods approaches are a promising line of research in the field of environmental evaluation and urban design. Insights and guidelines for the replication of the proposed methodological approach in other territorial contexts are also proposed

Multicriteria Evaluation of Urban Regeneration Processes: An Application of PROMETHEE Method in Northern Italy

The paper illustrates the development of an evaluation model for supporting the decision-making process related to an urban regeneration intervention. In particular, the study proposes an original multi-methodological approach, which combines SWOT Analysis, Stakeholders Analysis and PROMETHEE method for the evaluation of alternative renewal strategies of an urban area in Northern Italy. The article also describes the work carried out within an experts' panel that has been organized for validating the structuring of the decision problem and for evaluating the criteria of the model

Decision-making tools for urban regeneration processes: from Stakeholders Analysis to Stated Preference Methods

Urban regeneration operations are connected to the creation of a multiplicity of benefits, both economic and extra-economic, that range from the increase in the environmental quality to the amelioration of the urban image, from the valorization of the cultural heritage to the creation of economic development processes. The articles aims at proposing an integrated evaluation approach for addressing decision problems in the context of urban regeneration operations. Starting from the real case of the regeneration programme of the city of Collegno (Italy), the contribution proposes an original evaluation model based on the combined use of Stakeholders Analysis and Stated Preference Methods. The results of the research shows the people’s perception about the social value of urban regeneration programme and their Willingness To Pay for specific transformation operations

Evaluating the Interaction of Occupant Behavior and BACS (Building Automation and Control System) on Energy Consumptions: A Feasibility Analysis

As highlighted by the European Union legislation, the building sector is considered crucial in order to achieve the expected objectives in terms of reduction in greenhouse gases emissions to net zero and below. Furthermore, the impact that user’s behavior has on the energy consumption of residential buildings and consequently on well-being and comfort is well documented. In these regards, the application of Building Automation and Control System (BACS) aims at achieving an improvement in the user’s indoor comfort conditions, as well as a significant reduction in energy consumption due to an optimization of its delivery. This study verifies the potentialities of BACS installation to two case studies; a nearly Zero Energy single-family house and an energy retrofitted apartment located in the Northern Italy. In detail, different scenarios were designed, combining different energy consumers’ profiles, and building automation systems configurations. In order to measure the feasibility of the projects, Cost-Benefit Analyses (CBA) were performed, comparing investment cost with energy savings and extra economic benefits. The latter were estimated through a survey in terms of consumers' willingness to pay for the installation of smart devices in their homes through a contingent valuation in the iterative bidding format
