Addressing complex challenges in transformations and planning: A fuzzy spatial multicriteria analysis for identifying suitable locations for urban infrastructures
No full textIntegrated evaluation methods have started to gain more and more importance for supporting the decision-making process in the field of urban and territorial planning, contributing to the consideration of the multidimensionality of the elements involved and the multiple feedback of stakeholders. In the context of infrastructure location in cities, spatial multicriteria analysis is becoming increasingly relevant, thanks to its ability to synthesize the full range of aspects, through Multicriteria Decision Analysis (MCDA), and for the consideration of the spatial dimension, thanks to its integration of GIS data. The case study selected to test this mixed method is the new healthcare project for the metropolitan city of Turin (Italy). The decision where to locate a new healthcare facility is highly complex since many aspects have to be considered, spanning from technical to social factors, and from locational to environmental elements. This choice case study aims at highlighting the role of spatial multicriteria analysis to support Decision Makers (DMs) in the identification of suitable locations for urban facilities and shows the potential of the approach for increasing the participation of different stakeholders thanks to a simple visual representation of data and results. In particular, the research makes use of Analytic Hierarchic Process (AHP) and Fuzzy AHP (FAHP). The comparison of the two approaches shows that they can both be used for identifying suitable locations for urban infrastructures. However, this research demonstrates that AHP should be preferred in the case of the high relevance of all the criteria considered, whereas FAHP introduces more uncertainty in criteria weights assignment and reduces the burden of many spatial analyses with GIS
Green premium in buildings: evidence from the real estate market of Singapore.
No full textDifferent evaluation protocols were proposed to calculate the degree of sustainability of buildings and large-scale projects. In parallel, many studies focused on estimating the economic benefits delivered by green buildings according to the consumer choices using specific econometric models. The study aims to investigate the awareness of the benefits deriving from Green Mark-labeled buildings in Singapore through the application of the hedonic pricing method. In particular, the impact of the Green Mark was assessed in the multi-family building sector, starting from a transaction dataset of approximately 300,000 units sold between 2005 and 2017. Given the spatial complexity of the multi-family buildings market, spatial autocorrelation models were recommended. In particular, the spatial lag model (SAR) and the spatial error model (SEM) were applied. The paper implements the property valuation literature in the field of spatial econometrics related to sustainable certification. Besides, the research provided an assessment of the sustainability scheme over time, highlighting consumer behavior in different phases of the real estate market in Singapore. The results highlighted how spatial models filter the autocorrelation effect. As for the impact of Green Mark on the sale price of the apartments, the results confirmed that a green premium exists
Addressing Social Sustainability in Urban Regeneration Processes. An Application of the Social Multi-Criteria Evaluation
Full text linkThe 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 multi-methodological approach for assessing sustainability of urban projects
No full textThe purpose of this paper is to propose a multi-methodological approach for assessing the sustainability of urban projects. The proposed framework has the objective of addressing the different dimensions involved in the analysis (economic, environmental, social, technological, cultural, etc.), following the subsequent phases for the definition of the projects (from a very general masterplan to more detailed preliminary projects)
A strategic management based on multicriteria decision analysis: An application for the Alpine regions
No full textStarting from the case of the Alpine huts located in the Sondrio Province of the Lombardy Region (Italy), the paper proposes an integrated evaluation framework for addressing the need of the Italian Alpine Club to efficiently allocate economic resources in the context of the huts' management. The evaluation has been based on the combination of spatial multicriteria analysis and PROMETHEE method with the aim of defining the most suitable mountain huts to be renovated and valorised. The spatial multicriteria analysis model has allowed to evaluate the huts' system at a territorial macro-scale, putting in evidence the areas with the highest potentialities and those suffering from major risks, while the PROMETHEE application has been targeted to the examination of the huts at a micro-scale, selecting the huts in need of requalification with reference to a set of environmental and functional criteria. The results of the two aforementioned approaches have been merged with the aim of providing an aggregated evaluation of the overall system
Sustainability assessment of large dams: the case of a hydropower plant in Bulgaria
No full textThe increase in issues pertaining to the strategic assessment of territorial transformation has made it necessary to find new methods and tools that are able to consider the several factors at stake. The purpose of this paper is to examine the full range of impacts produced by a project in a territorial context and propose a real application concerning the construction of a new hydropower plant in Bulgaria. Making use of checklists, network chains and specific impact matrixes, the paper tries to evaluate the overall environmental compatibility of the project
