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.

L’obiettivo della tesi è ideare uno schema teorico del concetto multidimensionale di rischio territoriale, applicandolo successivamente ad un caso di studio sulle province italiane. Nel primo capitolo si delinea uno schema teorico del concetto di rischio territoriale, utilizzando una lettura del fenomeno di stampo sistemico, secondo cui il rischio è correlato positivamente a fattori di vulnerabilità territoriale e negativamente a fattori di resilienza. Il territorio viene rappresentato nelle tre dimensioni della sostenibilità, quella economica, sociale e ambientale, seguendo un approccio olistico. Nel secondo si applica lo schema teorico ad uno studio sulle province italiane. Si adotta una metodologia di sintesi a passaggi successivi, che prevede l’applicazione di tecniche multivariate. Si giunge ad un sistema di indicatori ed indici sintetici di vulnerabilità e resilienza economica, sociale e ambientale. Nel terzo si giunge agli indici sintetici di vulnerabilità e resilienza territoriale, confrontando metodi di aggregazione differenti. Si individuano così i sistemi locali più a rischio, perchè più vulnerabili e meno dotati di fattori di risposta al cambiamento. Si evidenziano elementi di originalità a livello di disegno teorico, per la trattazione del tema nelle dimensioni distinte Economia, Società e Ambiente, e a livello empirico, per l’utilizzo di metodologie di sintesi ibride. / The aim of the work is to provide a theoretical framework regarding the multidimensional concept of vulnerability of local systems, then applying it to a case study on Italian provinces. The first chapter outlines a theoretical framework of this concept, using a reading of the phenomenon according to a systemic mold, whereby the risk is positively correlated with spatial vulnerability factors and negatively with resilience factors. Region is represented in the three dimensions of sustainability, that is the economic, social and environmental ones, following a holistic approach. The second one applies the theoretical framework for a study on the Italian provinces. We have adopted a method of synthesis by successive steps, which provides the application of multivariate techniques. We arrive at an indicators system and composite indices of economic, social and environmental vulnerability and resilience. In the third one we reach the composite indices of vulnerability and resilience of local systems, comparing different methods of aggregation among themselves. Systems are identified as most at risk, because more vulnerable and less gifted with factors of response to change. Elements of originality are highlighted in terms of theoretical project for the treatment of the theme in the distinct dimensions Economy, Society and Environment, as well as, at empirical level, the usage of hybrid synthesis methods.

In questo lavoro viene presentata una metodologia di analisi del sistema delle infrastrutture verdi/grigie degli ambienti urbani classificabili per la loro sostenibilità ambientale. Questa analisi, permette la costruzione di una matrice che può essere analizzata matematicamente. Il problema di knapsack a scelta multipla è la base dell'approccio dove viene proposto un algoritmo risolutivo efficiente per ottenere la soluzione ottima lineare al problema, e tale metodo algoritmico viene incorporato in un algoritmo di programmazione dinamica per il problema intero. Nel caso trattato la seconda funzione obiettivo è stata utilizzata per minimizzare la differenza complessiva tra gli stati di competenza di ciascuna infrastruttura. Un ulteriore set di vincoli è stato usato nelle due macroclassi contenenti rispettivamente le infrastrutture di tipo pubblico e di tipo privato. Il modello utilizzato in questo lavoro è stato sviluppato ad-hoc per rappresentare il problema decisionale considerato e tutte le sue caratteristiche peculiari. Il modello sviluppato presenta dunque elementi di originalità, al meglio della conoscenza dell'autore. A migliorare l'accettabilità delle scelte progettuali è stato introdotto anche il processo di progettazione partecipata attraverso l'electronic town meeting. Le risultanze di tale approccio metodologico ottimizza l’impiego di risorse economiche limitate verso una migliore qualità della vita negli ambienti urbani. / In this paper we present a methodology for analyzing the system of green/gray infrastructure urban environments classified for their environmental sustainability. This analysis, allows the construction of a matrix that can be analyzed mathematically. The knapsack problem of multiple choice is the basis of the approach is proposed where a resolutive efficient algorithm to obtain the optimal solution to the problem linear, and this algorithmic method is incorporated in a dynamic programming algorithm for the entire problem. In the case treated the second objective function has been used to minimize the overall difference between the states of competence of each infrastructure. A further set of constraints has been used in the two macroclasses containing respectively the infrastructure type of public and private type. The model used in this work was developed ad hoc to represent the decision problem under consideration and all its characteristics. The model developed thus presents elements of originality, to the best knowledge of the author. To improve the acceptability of the design choices is also introduced the process of participatory planning through the electronic town meeting. The results of this methodological approach optimizes the use of limited financial resources towards a better quality of life in urban environments.

Sabaudia, « città di fondazione » italienne, est fondée en 1933, sous le régime fasciste. Elle fait partie du projet d’aménagement du territoire des marais Pontins, qui vise à assainir cette zone et à la doter d’un réseau de villes et de bourgs. Sabaudia va être qualifiée de « rationaliste », de « moderne », à la fois par la qualité de son plan, ouvert sur le paysage, et par son architecture.Notre attention s’est portée sur un ensemble d’indices concernant la réception de Sabaudia ; dès sa création se manifestent des confrontations entre les points de vue des architectes et ceux d’autres acteurs, notamment les politiques. La dévalorisation que connaît la ville suite à l’effondrement du régime fasciste est assez vite contrebalancée par les prises de positions, dans les années 60-70, de plusieurs intellectuels italiens engagés. L’intérêt des historiens pour la ville dont Bruno Zevi avait été le précurseur dès 1950, s’amplifie dans les années 80, ceci jusqu’à maintenant. À partir des années 2000, la ville connaît une mise en valeur de ses édifices, une patrimonialisation, qui reste néanmoins fragile, malgré la mise en place d’un parcours rationaliste et la restauration de certains de ses bâtiments.Ce travail de thèse, qui vise à écrire le récit d’une ville, contribue à explorer sous un autre angle le champ de la culture architecturale. Avec la notion de réception, nous cherchons à comprendre comment Sabaudia en traversant différentes périodes et critiques s’est trouvée impliquée dans une histoire plus globale, celle de l’Italie et de son rapport à l’architecture et à l’urbanisme. / The town of Sabaudia was built between 1933 and 1934 in the Pontine Marshes, Italy. It forms part of a sanitization and country-planning project led by the fascist regime. Its architecture is classified as «rationalist», «modern» by the quality of its plan, open towards the landscape and its architecture.Since its creation, its architecture has had an international impact and has given rise to deep confrontations between politicians and upholders of the architectural Modern Movement. After the war and the regime’s collapse, the city is depreciated but the positions of committed italian intellectuals during the 60’s-70’s change it. Historian’s interest, led by Bruno Zevi in 1950, has grown up from the 80’s until now. From the 2000s, the buildings of the city are promoted, registered as a common cultural heritage. However, despite the establishment of an urban rationalist route and the restoration of some of its buildings, this legacy is still fragile.This PhD dissertation aims at writing the story of a city, and at exploring in a different perspective the architectural culture. With the notion of reception, I try to understand how Sabaudia has gone throught different periods and critics, how it has been involved in a global history, the history of the Italy itself and its relation with architecture and urban planning. / Sabaudia, città di fondazione italiana è stata creata nel 1933, durante il regime fascista. Fa parte del progetto di bonificazione e di pianificazione dell’Agro Pontino. La città è stata definitia come «razionalista» a causa del suo piano, aperto sul paesaggio ed alla sua architettura «metafisica».La mia ricerca si é concentrata su diversi elementi che riguardano la fortuna critica della città ; a partire della sua creazione ci sono dei dibattiti tra i punti di vista degli architetti e quelli di altri attori, in particolar modo dei politici.La città conosce un deprezzamento dopo la caduta del regime che è velocemente contrastato negli anni 60-70 dalle posizioni di alcuni intellettuali italiani impegnati.L’interesse degli storici per la città - Bruno Zevi ne era stato il precursore fin da 1950 - cresce negli anni 1980, fino ad oggi. Dagli anni 2000, gli edifici della città sono promossi, e diventano anzi patrimonio (sebbene fragile) con l’istituzione d’un percorso urbanistico razionalista ed il restauro di alcuni edifici.Questa tesi di dottorato ha lo scopo di scrivere la storia d’una città, l’esplorazione di un altro punto di vista sulla cultura architettonica. Con la nozione di ricezione, cerco di capire come Sabaudia attraverso parrecchi momenti critici è stata coinvolta in una storia più globale, quella dell’Italia e del suo rapporto all’architettura ed all’urbanistica.

The current state of energy and climate transition presents several challenges that are currently not optimally addressed by planning and design practices. Indeed, cities play a central role in this transition, as they are within the main causes of climate change as well as extremely vulnerable to its effects, such as extreme events. In this context, the disciplines of urban planning and design are a great resource for promoting mitigation and adaptation strategies. However, there is a gap between scientific research on the issues and the actual implementation of the resources, mainly due to the inability of planning tools to address these needs, the difficulty of transforming the existing built environment and the engagement of citizens in these processes. These issues can be translated into four knowledge gaps that can be addressed by the disciplines of planning and design: lack of explicit considerations of resilient pathways, lack of innovative implementation tools, local resistance towards landscape transformations, silo thinking. The goal of the thesis is to identify, develop and evaluate climate-sensitive planning and design strategies, considering the environmental criteria, the urban areas and the people who live in them. The research is practice-oriented and gives directions on how to apply scientific knowledge through practices for a responsive and landscape-inclusive climate-energy transition. Specifically, it aims to combine several challenges and promote holistic procedures balancing adaptation and mitigation strategies as well as to include the concept of landscape in the transition. The proposed methodologies are evidence-based, performance-based and landscape-inclusive, connecting different scales of intervention, disciplinary tools, and practices of planning and design. In other words, the thesis promotes urban regeneration for climate and energy transition through an integrated approach between landscape, city, and buildings. This integrated approach addresses the following dimensions of urban challenges: social, environmental, economic, and health.

En este trabajo se estudian las áreas residenciales de edificación abierta en la ciudad de Valencia en el período comprendido entre el Plan General de Valencia y su Cintura de 1946 y el Plan General de Ordenación Urbana de Valencia de 1988. La forma de crecimiento característica de la ciudad moderna, mediante la creación de polígonos (conjuntos integrados por viviendas y equipamientos, desarrollados a partir de un proyecto unitario que engloba tanto la urbanización como la edificación), no es la predominante en la perifería de Valencia, donde el crecimiento se produce mediante el tradicional casa por casa, a partir de unos planes parciales que, pese a su parecido formal con los de los polígonos, debido al recurso a la edificación abierta como base del diseño, son en realidad meros planos de alineaciones y volúmenes. Las áreas residenciales de edificación abierta de Valencia, pese a su morfología, tienen más puntos en común con los ensanches tradicionales que con los polígonos, debido a su localización, que es de continuidad con respecto a los demás tejidos urbanos de Valencia, debido a su alta densidad y compacidad, resultado de la escasa previsión de reservas de suelo para equipamientos y, debido, por último a su carácter mixto, de su consecuencia de la alta proporción de manzanas formadas por bloques lineales situados sobre zócalos comerciales. / Pérez Igualada, J.

El propósito principal de esta tesis es el conocimiento profundo del estado de la cuestión de un ámbito complejo, como es el patrimonio cultural inmerso en el campo del urbanismo, con la intención de que el análisis conduzca a propuestas útiles para la mejora de la conservación y difusión de los valores patrimoniales, a través de la técnica de planificación territorial y urbanística. Supeditados a la materia, como objetivos de conocimiento y análisis del trabajo, se estudian temas como el tratamiento del patrimonio urbano en el ámbito de la gestión cultural y más concretamente, de los planes estratégicos de cultura. Se comprueba la vigencia de los instrumentos de protección del patrimonio arquitectónico y su aplicación en la práctica de la gestión urbanística. Se analizan las técnicas de registro y catalogación de inmuebles y la adaptación de las TICS a estas prácticas tradicionales, mediante un sistema E-heritage como plataforma digital de datos, que garantice la operatividad de la gestión, y la comunicación y difusión del patrimonio por las administraciones. Asimismo, se estudian las técnicas de ordenación del patrimonio arquitectónico en la planificación urbanística de la Comunidad Valenciana, tanto a escala territorial como en los ámbitos urbanos de la ciudad de Valencia y núcleos de menor población. A partir del análisis, se aportan mejoras en la técnica de catalogación y ordenación del patrimonio arquitectónico, a fin de su protección, con especial atención en optimizar los medios de catalogación y normas de protección de los núcleos históricos menores valencianos. Como contribución, se propone la actualización y digitalización del catálogo de la ciudad Valencia, con incorporación de un sistema E-heritage, exportable al resto de catálogos municipales, como herramienta básica en la gestión del patrimonio, en consecución de la primera fase hacia su conservación, el conocimiento de los valores que llevaron a su catalogación. / Broseta Palanca, MT.

[EN] Great Britain has always been a pioneer in the field of urban planning during key stages in its history, the Garden City and the New Towns are two models that have been decisive in urban culture, and have been used with great profusion internationally. The influence that the development of the Modern Movement had throughout the twentieth century, is another determining factor of the course of the mentioned models and their commitment with these new resources in architectural and urban settings. The experience of Harlow, Milton Keynes and Thamesmead shed light on these and other topics of interest for future developments. Deepening into aspects such as their instrumental and compositional definition, their own urban development and programmatic aims, the shapes of each settlement and its relationship with the territory, their urban structure, their compositional units, the role and settings of the civic centres, their architectural typologies and their landscape treatments, allow us to make a compared diagnosis of these experiences. This, together with some other data, will help us reach conclusions on the compliance of their aims and how they have evolved, their current situation and their future expectations. This research proposes to make a current reading of them in terms of the greater or lesser implications of their ideologies and their possible influence on the challenges that the urban planning and design faces nowadays. The New Towns are an alternative to the sprawl of large cities and a dispersed growth on the territory, a problem still to be resolved and inherited from the last decades in Europe. / [ES] Gran Bretaña ha sido pionera en materia de planificación urbanística en etapas clave de su historia. La Ciudad Jardín y las New Towns son dos de los referentes que han sido decisivos para la cultura urbanística, y utilizados con gran profusión a nivel internacional. La influencia que a lo largo del siglo XX tuvo el desarrollo del Movimiento Moderno fue otro factor determinante del recorrido de ambos modelos y de su compromiso con nuevos recursos en la configuración arquitectónica y urbanística. La experiencia de las New Towns arroja luz sobre esos y otros temas de interés para futuros desarrollos. Estudiar en detalle tres de ellas, Harlow, Thamesmead y Milton Keynes, y profundizar en aspectos como: su definición instrumental y política, su propia formulación urbanística y objetivos programáticos, la identidad física de cada asentamiento y su relación con el territorio, la estructura urbana, las unidades compositivas, el papel y la configuración de los centros cívicos, sus tipologías arquitectónicas o sus tratamientos paisajísticos, nos permite hacer un diagnóstico comparado de dichas experiencias. Este diagnóstico, junto con otros datos nos aproxima a algunas conclusiones sobre el cumplimiento de sus objetivos, el modo en que han evolucionado, su situación actual y sus expectativas de futuro. La investigación propone hacer una lectura actual de las mismas en cuanto a la mayor o menor trascendencia de sus idearios y su posible vigencia sobre los retos a los que el Urbanismo actual se enfrenta. Las New Towns constituyen una alternativa al crecimiento desmedido de las grandes ciudades y las formas de ocupación indiscriminada del territorio, un problema todavía por resolver heredado de las últimas décadas del siglo XX en Europa. / [CA] Gran Bretanya ha sigut pionera en matèria de planificació urbanística en etapes clau de la seua història. La Ciutat Jardí i les New Towns són dos dels referents que han sigut decisius per a la cultura urbanística, i utilitzats amb gran profusió a nivell internacional. La influència que al llarg del segle XX va tindre el desenvolupament del Moviment Modern va ser un altre factor determinant del recorregut d'ambdós models i del seu compromís amb nous recursos en la configuració arquitectònica i urbanística. L'experiència de les New Towns dóna llum a eixos i altres temes d'interés per a futurs desenvolupaments. Estudiar amb detall tres d'elles, Harlow, Thamesmead i Milton Keynes, i aprofundir en aspectes com: la seua definició instrumental i política, la seua pròpia formulació urbanística i objectius programàtics, la identitat física de cada assentament i la seua relació amb el territori, l'estructura urbana, les unitats compositives, el paper i la configuració dels centres cívics, les seues tipologies arquitectòniques o els seus tractaments paisatgístics, ens permet fer un diagnòstic comparat d'eixes experiències. Aquest diagnòstic, junt amb altres dades, ens aproxima a algunes conclusions sobre el compliment dels seus objectius, el mode en què han evolucionat, la seua situació actual i les seues expectatives de futur. La investigació proposa fer una lectura actual d'elles pel que fa a la major o menor transcendència dels seus idearis i la seua possible vigència sobre els reptes a què l'Urbanisme actual s'enfronta. Les New Towns constituïxen una alternativa al creixement desmesurat de les grans ciutats i les formes d'ocupació indiscriminada del territori, un problema encara per resoldre heretat de les últimes dècades del segle XX a Europa. / Deltoro Soto, MJ.

[ES] Este trabajo de investigación explora y presenta formas contemporáneas del espacio público que han sido denominadas experiencias alternativas emergentes, las cuales cuestionan distintas prácticas de la planeación y gestión urbana convencional, y los conceptos tradicionales que han definido y caracterizado al espacio público como ámbito de estudio urbano. Las experiencias emergentes surgen de manera espontánea con iniciativas participativas, son más cercanas a las realidades de las comunidades y barrios, y generan identidad, apropiación y empoderamiento de la ciudadanía. Se contemplan a partir de varios métodos como el placemakig, el urbanismo táctico y el urbanismo hecho a mano; se desarrollan a partir de las acciones resultantes de procesos participativos; se conciben a partir de medios como el reciclaje urbano y el reciclaje desde la materialidad; e incluyen expresiones provenientes del arte urbano. Se explican en la tesis a partir de diversas posturas teóricas y un amplio ejercicio de casos de estudio de diversas ciudades en el mundo, expuestos en cuatro grupos: los efímeros, los consolidados desde la escala barrial, los estructurados desde el arte y los semilleros. La resignificación del espacio público es la conclusión de este trabajo, desarrollada por nuevos insumos provenientes de estas manifestaciones, abriendo un debate sobre otros caminos de concebir el espacio público, resaltando las características de cohesión, de la prioridad de las actividades por encima de la infraestructura física, de la posibilidad de gestión a través de tácticas y formas efímeras que permiten ser escalones para el mejoramiento, lo fundamental de la participación ciudadana e intermediación de colectivos en las distintas etapas de los proyectos, la pequeña escala de las intervenciones, y la importancia del espacio público como factor de bienestar para las personas como interfaz social y de calidad de vida de las ciudades. / [CA] Este treball d'investigació explora i presenta formes contemporànies de l'espai públic que han sigut denominades experiències alternatives emergents, les quals qüestionen distintes pràctiques de la planeación i gestió urbana convencional, i els conceptes tradicionals que han definit i caracteritzat a l'espai públic com a àmbit d'estudi urbà. Les experiències emergents sorgixen de manera espontània amb iniciatives participatives, són més pròximes a les realitats de les comunitats i barris, i generen identitat, apropiació i apoderament de la ciutadania. Es conceben a partir de diversos mètodes com el placemakig, l'urbanisme tàctic i l'urbanisme fet a mà; es desenrotllen a partir de les accions resultants de processos participatius; es conceben a partir de mitjans com el reciclatge urbà i el reciclatge des de la materialitat; i inclouen expressions provinents de l'art urbà.

La resignificació de l'espai públic és la conclusió d'este treball, desenrotllada per nous insumos provinents d'estes manifestacions, obrint un debat sobre altres camins de concebre l'espai públic, ressaltant les característiques de cohesió, de prioritat de les activitats per damunt de la infraestructura física, de la possibilitat de gestió a través de tàctiques i formes efímeres que permeten ser escalons per al millorament, el més important de la participació ciutadana i intermediació de col·lectius en les distintes etapes dels projectes, la reduïda escala de les intervencions, i la importància de l'espai públic com a factor de benestar per a les persones com a interfície social i de qualitat de vida de les ciutats. / [EN] This research explores contemporary forms of public space that have been called emerging alternative experiences, which question different practices of conventional urban planning and management, and the traditional concepts about the characterization and definition of public space as a field of urban study. Emerging experiences arise spontaneously with participatory initiatives, are closer to the realities of communities and neighborhoods, and generate identity, ownership and empowerment of citizens. They are conceived from some methods like the placemaking, the tactical urbanism and the handmade urbanism; they have been developed by initiatives and actions of participatory processes; they are conceived through the urban recycling and recycling from materiality; and include expressions from urban art. The thesis explains the alternative experiences based on theoretical positions and a wide exercise of case studies from different cities in the world, exposed in four groups: ephemeral, consolidated from the neighborhood scale, structured from art and initiators. The resignification of public space is the conclusion of this work, developed by new inputs from these manifestations, creating questions about other ways of conceiving public space, the characteristics of cohesion, the priority of activities over physical infrastructure, the possibility of management through tactics and ephemeral forms as a previous steps for improvement, the fundamentals of citizen participation and mediation of organizations in the different moments of the projects, the small scale of the interventions, and the importance of public space as a factor of well-being for people as a social interface and quality of life in cities. / Bueno Carvajal, JM.
