This PhD thesis provides design strategies to control changes produced in mountains places and landscapes following constructions of roads. Strategies are based on the activation of unexpressed potentialities in places, although compromised, characterized by presence of roads. With the term unexpressed potentialities we refer to functions, attitudes, uses which, during the process of road realization, have not found an appropriate design solution. Topic of the thesis is to demonstrate that these design gaps can be properly addressed by an architecture project, obtaining two results: create a link between places, landscapes and roads and consolidate the participation of architecture discipline in a field (roads production) in which, today in Italy, it is less integrated than others. Changes in mountain landscapes are characterized by morphology and orography of the territory crossed: the factor that most influences in this direction is the verticality of the space. This specificity is discussed in the thesis through the analysis of road segments, infrastructure nodes or other specific situations, divided according to the topography in which there are: high gradients, slope or bottom of valleys. Specific characteristics which correspond to the three different orographic situations are explained by an interpretative study of the cross section, highlighting the potentiality of the space related with its vertical dimension. Most study cases belong to the geographical area of Trentino Alto Adige, an Italian region characterized by mountain landscapes. Some study cases are taken from other Italian regions or known experiences of the international context. The proposed strategies are developed through study of architectural projects, joined by devices that interpret the vertical (overlapping, slope and difference in altitude) of the spaces, reproposable in cases of mountain road. All strategies can be applied at any step of road production, from concept to design to construction. In addition, and we assume that this is the most frequent case, can be applied ex post, when the road is built, intervening to change situations already in place.

Contemporary debate on the future of urban areas is open and far from finding a convergence point among disciplines. As environmental concerns rise globally and connections between urbanity and ecology are being developed, urban-rural fringes are still an overlooked territory. The thesis proposes a shift in the focus as traditional frameworks have proven to be inadequate to track land-use changes in these hybrid spaces. Starting from selected key concepts, a compelling narrative on hybrid urban-rural fringes is proposed. The thesis benefited from the work done within the Interreg Alpine Space project “Los_Dama!”. This allowed to bridge the gap between research and practice and to directly investigate local planning tools in their adoption process to understand the approach to urban-rural fringes and investigate the role of agriculture. The comparison of the tools and direct fieldwork with local stakeholders supported the understanding of barriers in the implementation of hybrid performative landscapes.

Smart energy city (SEC) development is a component of the urban development initiative smart city, which has been a popular response to the global energy challenge in Europe during the past two decades. SEC development aims to increase the sustainability of urban energy systems and services. Since 2011, SEC development has been supported by the European Commission as part of the Strategic Energy Technology plan (SET-Plan) and through the European Union Programmes for Research and Technological Development (specifically FP7 and Horizon 2020). This, along with the promising vision of SEC development and considerable financial support by the private sector, has encouraged numerous European cities to initiate SEC projects. Successful implementation of these projects at the urban scale is crucial to achievement of urban energy objectives and sustainability of future urban development. The here presented thesis aims to support urban decision-makers towards successful implementation of urban scale smart energy city development in Europe. The study includes three stages. The first stage is dedicated to conceptual analysis. Within this stage, I conceptualized smart city through a keyword analysis of existing literature on the concept. Then, within the context of the smart city concept, I defined SEC development through literature review and expert knowledge elicitation. The second stage is dedicated to empirical investigation. Using the definition of SEC development, I distinguished and investigated 43 previously implemented SEC projects to identify common barriers that hinder successful implementation of SEC development. In addition, I proposed a new multi-dimensional methodology that allows a simultaneous prioritization of barriers against their probability, the level of impact, scale, origin, and relationship with other barriers. The third stage of the thesis is dedicated to learning methodologies that allow efficient transfer of knowledge from the past SEC experiences to the new SEC developments. I introduced the application of two learning methodologies that support decision-makers to predict barriers to the implementation of a new SEC project: case-based learning and decision tree learning. The former predicts barriers based on internal similarities between the new SEC project and the past projects. The latter uses the past projects and creates a predictive model for each barrier based on internal and external project characteristics. These models are later used to predict barriers to a new SEC project. Both methodologies were tested in a new SEC project, named SINFONIA. The conceptual analysis revealed that application of information and communication technologies, the collaboration of multiple stakeholders, integration of multiple urban domains, and sustainability evaluation are the constant characteristics (i.e. principles) of smart city and SEC development. It resulted in, to the best of my knowledge, the first multi-dimensional and comprehensive definition of SEC development, revealing its principles, objectives, domains of intervention, stakeholders, time and spatial dimensions. Furthermore, a list of smart energy solutions in each SEC domain of intervention was provided. The empirical investigation of the past SEC projects resulted in the identification of 35 common barriers to the implementation of SEC development, categorized in policy, administrative, legal, financial, market, environmental, technical, social, and information and awareness dimensions. The barrier prioritization showed that barriers related to collaborative planning, external funding of the project, providing skilled personnel, and fragmented ownership should be the key action priorities for SEC project coordinators. Application of case-based learning methodology resulted in identifying five past SEC projects that were the most similar to the SINFONIA project in terms of project internal characteristics. Investigating the barriers to the similar projects revealed that fragmented ownership is the most probable barrier to implementation of SINFONIA project. Application of the decision trees methodology resulted in generation of 20 barrier models, four of which showed a very good performance in prediction of barriers: lack of values and interest in energy optimization measures, time-consuming requirements by European Commission concerning reporting and accountancy, economic crisis, and local unfavorable regulations for innovative technologies. None of these four barriers were predicted to occur in the SINFONIA project. The application of this method in the SINFONIA showed a higher predicting power when a barrier was absent. The findings of the here presented thesis contribute to successful implementation of SEC development by supporting decision-makers in different phases of SEC projects. The results of the conceptual analysis contribute to a common understanding and foster the dialogue on the concept among various SEC stakeholders, particularly decision-makers and urban planners. The results of the empirical investigation lead to a better comprehension and evaluation of the barriers to the implementation of SEC projects in order to efficiently allocate resources to mitigate barriers. The proposed learning methodologies proved to be promising in helping decision-makers to identify similar projects to a new SEC development and to predict barriers to the implementation of new SEC projects. The thesis concludes that SEC is an outstanding urban development that can make a valuable contribution to the sustainability of urban energy systems. The specific characteristics of SEC development pose new challenges to the future smart and sustainable urban planning. Nevertheless, SEC development brings about unprecedented opportunities for integration and application of advanced quantitative techniques with current urban planning methods. This allows efficient knowledge transfer in not only intra-urban but also inter-urban levels in order to provide a collaborative, integrated and constructive movement towards successful implementation of SEC projects and sustainability of future urban development.

In an attempt to make concrete linkages between neighborhood change and the boundary-making paradigm, this field and historical study of a New York City's neighborhood, addresses the influences of displacement, housing- abandonment and resettlement in Super-gentrification processes on 1) the types of institutions that emerged to represent different class interests; 2) the types of social groups that came to inhabit the neighborhood; 3) the pattern of that evolution over time; 4) the particular goals, values, and morals that such community organizations evolved; and 5) the social status displays carried out in cultured consumption in housing and leisure. Employing a multi-methodological and theoretical approach, the study follows the evolution and development of neighborhood change over forty years through the analysis of social groups and their community organizations (looking at archival documents for the past and by in-depth interviews, shadowing and ethnographic observation for the present time), census data analysis, archival/documental research, and visual data. Community organizations emerged, on the one hand, to represent different class interests - improvement, mandated, ideological - and to emphasize liberal progressive values, on the other. This emergence followed historical and geographical patterns of accelerating gentrification. The study argues that four waves of gentrification showed up across the time and tended to concentrate in four different neighborhood areas, where the incoming groups formed parallel boundary shifts. Accordingly, I found that different waves of gentrification were associated with the emergence of different types of Gentrifiers over time, and this had to do with the changing role of post-industrial cities within the American economy, the processes of government/local institution interventions in the neighborhood housing market, the changes in class interests, morals and ideologies, and the increased aestheticized re-scriptings of neighborhood housing choices and lifestyles. Such aesthetic appreciation operated for gentrifiers as a visible marker of social status. As residential displacement, the disappearance of "old" local stores, and their replacement of upscale shops entailed forms of social inequality that enhanced the lifestyle of new waves of gentrifiers (raising housing values and rents) while, at the same time, forced out morally (by alienation) or practically (by displacement) long-term residents, who helped produce the neighborhood socio-cultural fabric. Diversity and aesthetic appeal seemed to underlie the motives of wealthier, well-educated newcomers to move into the neighborhood. Interestingly, those have not been changing throughout the different waves of gentrifiers who came to inhabit the community in the last 40 years. However - during the process of Super-gentrification - I found that the more they populate the neighborhood, the more it becomes homogenized and less richly diverse, still quite progressive but in a different way. I would say, in a privileged progressive way. Despite the fact that the moral order of these institutions has always been the one of community solidarity, culture, education, and growth, I observed at the same time the playing out of the most common paradox of gentrifiers. The desire of diversity and the producing of difference. This is, I believe, the central problem of gentrification: the balance between, or the combination of, pleasure and power. Balancing pleasure and power is a social, political, and moral problem. It brings together many of the concerns about gentrification, the desire for (and the loss of) diversity, and expresses the central thesis of this study.
