Multi-Criteria Analysis and Decision-Making Approach for the Urban Regeneration: The Application to the Rimini Canal Port (Italy)
Full text linkIn recent decades, urban settlements have been greatly affected by globalisation, climate change, and economic uncertainty. When designing cities, these factors should be taken into account and adapted to the different contexts involved. The redevelopment of degraded urban areas is the first step toward achieving the sustainability aims set out in the Sustainable Development Goals. In this context, evaluation methods are required in the decision-making process, considering different social, economic, and environmental aspects to define the correct policies and actions for city redevelopment. In this paper, an evaluation methodology is proposed in order to obtain a priority scale of interventions for urban regeneration. Starting from on-site inspections to better know the current scenario, a set of indicators is established to evaluate the urban quality. Criticalities and potentials emerge through SWOT analysis and, with the ANP-BOCR method, the priority scale of the identified scenarios is defined. This decision-making approach was applied to the case study of the Rimini Canal Port, in the northeast of Italy, which is a degraded area of the city. This methodology is a tool that can be used in the future by decision makers (DMs) for the redevelopment of small port areas within similar urban contexts
Metodo di valutazione speditiva della circolarità negli interventi di riqualificazione del patrimonio edilizio esistente. Applicazione a quattro casi di studio in Europa / Simplified method for assessing the circularity in the requalification of the existing building heritage. Application to four European case studies.
No full textThe decarbonisation of the building sector is a key issue in facing the climate crisis. The concept of circularity in the built environment is becoming more and more widespread to pursue this goal. This approach proposes the design of buildings paying particular attention to the origin of the materials and energy sources used for their manufacture and transport, as well as to their ability of assembly and disassembly to adapt to future uses and to minimise the production of construction and demolition waste. Lots of methods and tools for assessing the circularity of buildings are already available, but they are scarcely employed.
One of the possible causes of the low employment of these tools lies in their complexity and difficult accessibility by stakeholders and users, in particular those not specialised in the construction sector. This reflection led to the purpose of defining a simplified method for assessing the level of circularity of buildings by evaluating the implementation of different intervention scenarios.
This contribution comes up with an overview of the state of the art of European research scenarios and the currently most widespread best practices that meet the requirements of circular design. Subsequently, the methodology called “EASY – Express ASsessing tool for CircularitY”, developed by the University of Bologna in the framework of H2020 EU project “DRIVE0” is reported. This methodology is aimed at identifying a numerical index for the evaluation of the circularity level of the overall building. This latter was compared with a cradle-to-gate LCA analysis performed using the OneClick LCA Software.
Finally, the paper reports the results obtained from applying this method to four case studies in Europe, for which the feasibility study has approved the implementation of volumetric additions
Circular approach for deep renovation of historic building heritage. The case of a manor villa in Argelato, Bologna
No full textCircular approach for deep renovation of historic building heritage. The case of a manor villa in Argelato, Bologna
No full textBuildings are responsible for about 40% of the European energy consumption and 36% of greenhouse gas emissions from energy. As stated by the European Renovation Wave, effective actions - both at the policy-legislative and academic and corporate research level – are crucial to making Europe climate-neutral by 2050. In this framework, the “DRIVE 0” European Horizon 2020 project is aimed at developing innovative solutions for energy refurbishing the existing buildings, based on a circular approach. The circular solutions developed in cooperation between universities and factories are intended to be prototyped and implemented in real pilot cases in order to test their feasibility. This paper presents the specific Italian demo case located in Argelato, constituted of a manor villa included in the “Corte Palazzo” building complex. Two different envelope solutions – a traditional ETICS system and an innovative Plug&Play solution - are applied to the building in order to compare their circularity. The results of the analyses, which consider not only the Embodied Energy and Embodied CO2, but also parameters linked to the Design for Disassembly, Materials Origin, and Re-Usability of materials and components, bring out some important reflections on the actual lack of application of a circular approach to historic buildings
Urban Regeneration and Soft Mobility: The Case Study of the Rimini Canal Port in Italy
Full text linkThe increasing need to reduce emissions and the environmental impact of urban areas to meet European decarbonisation goals motivates the selection of the Rimini Canal Port as a case study within the FRAMESPORT project, part of the European Interreg Italy–Croatia programme. A preliminary historical–documental and urban regulations analysis of the context allowed the identification of the main criticalities and potentials through a SWOT analysis. The central role of the stakeholders enabled the creation of a successful participatory co-design process developed through online surveys. Critical issues that emerged during the data collection phase were prioritised through a BOCR model, a powerful multi-criteria analysis tool. The project phase then focused on the resolution of the two main critical issues that emerged: the improvement of cycle/pedestrian paths, and the raising of the flooding docks in the Canal Port area. This article intends to demonstrate the strong influence of soft mobility in urban regeneration projects, and how an improvement of the quality of cycle/pedestrian paths can increase the quality of urban spaces. The new paths create a green infrastructure that contributes to a reduction in pollutant emissions through the promotion of sustainable mobility systems and an increase in green urban spaces
Assessing and Developing Circular Deep Renovation Interventions towards Decarbonisation: The Italian Pilot Case of “Corte Palazzo” in Argelato
Full text linkDecarbonisation in the construction sector, consisting of a process based on the abandonment of fossil resources and the achievement of greater resource efficiency, is increasing in both new construction and renovation. The concept of circularity is seen as a strategy to reach this goal. The direct environmental impact of building designs can be quantitatively evaluated by assessing total mass, embodied energy, and embodied CO2 in combination with circularity criteria, such as design for disassembly, materials and product origin, as well as recovering potential. This paper presents a method for easily assessing these parameters, thus obtaining a Building Circularity Indicator. To validate the method, its application in a pilot case of a manor villa located in Argelato (Bologna, Italy) is provided in the framework of the European Horizon 2020 project “DRIVE 0—Driving decarbonization of the EU building stock by enhancing a consumer-centred and locally based circular renovation process”. The deep renovation intervention developed is aimed at increasing energy performance by pursuing a circular approach that has rarely been tackled in protected heritage. Furthermore, the benefits of a circular versus a linear strategy are demonstrated through an LCA as well as LCC analyses assessing the environmental and economic impact of the intervention. The research results validate the proposed method as a tool to support operators in the construction sector
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
