The city as a learning gamified platform

The area of mobile city guides has grown really fast in the last years based on new mobile capabilities. This growth has been fostered by the evolution of ubiquitous systems and the great penetration of smartphones in the society. In this paper we propose a generic model to support a new way of visiting the city: instead of as a place for tourism, we see it as a place for learning in which located educational resources are available for end users. The model has been conceived as a way to encourage them to create their own educational tours, in which Learning Points Of Interest are set up to be discovered. Two main use cases are supported by the model: formal (conducted by a teacher) and informal (no educator is related to the learning experience) outdoor mobile learning. Details about the impact of the conjunction of tourism, learning and gamification dimensions in the model design, as well as about the model itself are provided. Finally, a mobile application prototype developed in the context of the FI-CONTENT European project is presented as a proof of concept of the model.

A dynamic, probabilistic model for city building

The problem of interdependence between housing and commuting in a city has been analysed within the framework of welfare economics. Uncertain changes overtime in the working population has been considered by means of a dynamic, probabilistic model. The characteristics of irreversibility and durability in city building have been explicitly dealt with. The ultimate objective is that the model after further development will be an auxiliary tool in city planning.

The Interior City Infinity and Concavity in the No-Stop City (1970-1971)

In the late 60s it had become clear how the environment technification had allowed some typologies (supermarkets, car parks, factories) to reach potentially unlimited built depths becoming, therefore, independent from the outside. The No-Stop City is born from a very simple idea: to extend this technification to the totality of built reality encompassing, not only almost all functions, but ultimately, the whole city. This operation has paradoxical effects: as architecture grows, it loses most of the features that have traditionally defined it. A dissolution by hypertrophy that gives rise to an homogeneous, concave and potentially infinite space. But beyond the pure technical feasibility, there are two key influences, seemingly contradictory, that explain this endeavor for an interior and endless city: Marxism and Pop Art. The project is, in many senses, a built manifesto reflecting the militancy of the group members within the Italian Marxism. But it is also the embodiment of the groups declared interest in Pop Art, popular culture and mass society. The cross-influence of communism and consumerism explains this "quantitative utopia" in which the society and the factory, the production and consumption, would match. A city based on the centrality of consumer products and the subsequent loss of prominence of architecture, in which the urban phenomenon, while spreading endlessly over territory, ignoring its rural exteriority, dissolves the home as a sphere of privacy, ignoring its domestic interiority. A project, also in the wake of Marshall McLuhan, that illustrates like few others the conversion of the urbane into a virtually omnipresent "condition" and that still interrogates us with questions that are, on the other hand, eternal: What is a building? What is a city?

Andrea Branzi y la “Città senza architettura”: De la No-Stop City a los modelos de urbanización débil

El tema de estudio de esta tesis son las propuestas urbanas que Andrea Branzi ha desarrollado durante los últimos cincuenta años, centrándose especialmente en aquellas más elaboradas y completas: la No-Stop City (1970-71), que elabora como miembro del grupo radical Archizoom, y dos de sus modelos de urbanización débil, Agronica (1995) y el Master Plan para el Strijp Philips de Eindhoven (2000). Se trata de una parte de su obra que ha mantenido constante, a lo largo del tiempo, una propuesta de disolución de la arquitectura de notable consistencia que puede describirse con la fórmula “città senza architettura”, acuñada por él mismo. Una voluntad que ya se apunta en la muy variada producción de Archizoom previa a la No-Stop City, y que cristaliza y se hace explícita en este proyecto que aspiraba a: “liberar al hombre de la arquitectura”. A pesar de la continuidad de esta idea en el tiempo, la ciudad sin arquitectura de Branzi ha evolucionado claramente dando lugar a distintos tipos de disolución. Una disolución que, obviamente, no supone la efectiva desaparición de la disciplina, sino la formulación de una arquitectura “otra” basada en un replanteamiento radical de la naturaleza y el papel de la misma. Esta agenda contra la disciplina se ha desplegado a través de una serie de temas que socavan el objeto arquitectónico canónico (su vaciamiento expresivo, la pérdida de importancia de la envolvente y la forma acabada, el carácter anticompositivo, la independencia entre forma y función, la mutabilidad en el tiempo…), pero va más allá al poner en crisis el rol que la propia arquitectura ha tenido en la configuración material, política y simbólica del hábitat humano. Una pérdida de protagonismo y centralidad en la sociedad contemporánea que, en el discurso del arquitecto, implica necesariamente un papel subordinado. De este proceso de disolución surge un nuevo tipo de ciudad en la que la forma urbana o se ha perdido o se ha convertido en superflua, en la que se ha disuelto la zonificación funcional, cuyos espacios interiores se hallan en un proceso de permanente reprogramación que ignora las tipologías, que trasciende la división entre lo urbano y lo agrícola y que es, ante todo, un espacio de flujos y servicios. La crisis de la ciudad tradicional implica, en definitiva, un cambio en la naturaleza misma de lo urbano que pasa de considerarse un lugar físico y construido, a convertirse en una condición inmaterial y virtualmente omnipresente que se despliega independientemente de su soporte físico. En las investigaciones urbanas de Branzi convergen, además, muchas de las reflexiones que el arquitecto ha desarrollado sobre, y desde, las distintas “escalas” de la actividad profesional: diseño, arquitectura y urbanismo. Estas propuestas no sólo cuestionan las relaciones establecidas entre objetos, edificios, ciudades y territorios sino que ponen en cuestión estas mismas categorías. Unas ciudades sin arquitectura que se basan, en última instancia, en plantear preguntas que son muy sencillas y, por otra parte, eternas: ¿Qué es un edificio? ¿Qué es una ciudad? ABSTRACT The subject of study of this thesis are the urban proposals developed by Andrea Branzi over the last fifty years, with a special focus on the more developed and comprehensive ones: the No- Stop City (1970-1971), produced as a member of the architettura radicale group Archizoom, and two of his “weak urbanization models”: Agronica (1995) and the Master Plan for Philips Strijp in Eindhoven (2000). This area of his work has kept, over time, a remarkably consistent proposal for the dissolution of architecture that can be described with the motto città senza architettura (city without architecture), coined by himself. A determination, already latent in the very diverse production of Archizoom prior to No-Stop City, that crystallizes and becomes explicit in this project which was aimed to "liberate man from the architecture." Despite the continuity of this idea over time, Branzi’s city without architecture has clearly evolved leading to different types of dissolution. A dissolution that, obviously, does not mean the effective demise of the discipline, but rather, the formulation of an architecture autre based on a radical rethinking of its nature and role. This agenda against the discipline has been developed through a number of issues that undermine the canonical architectural object (its expressive emptying, the loss of importance of the envelope and the finished shape, the anticompositional character, the independence between form and function, the mutability over time...), but goes beyond it by putting into crisis the role that architecture itself has had in the material, political and symbolic configuration of the human habitat. A loss of prominence and centrality in contemporary society that, in the architect’s discourse, implies a subordinate role. From this dissolution process, a new type of city arises: a city where urban form has been lost or has become superfluous, in which functional zoning has dissolved, whose interiors are in a permanent process of reprogramming that ignores typologies, that transcends the division between urban and agricultural and becomes, above all, a space of flows and services. Ultimately, the crisis of the traditional city implies a change in the very nature of the urban that moves from being regarded as a physical and built place, to become an immaterial and virtually omnipresent condition that unfolds regardless of its physical medium. Many of the ideas Branzi has developed on, and from, the different "scales" of professional activity (design, architecture and urbanism) converge in his urban research. These proposals not only question the relations between objects, buildings, cities and territories but also these very categories. Cities without architecture that are based, ultimately, on raising simple questions that are, on the other hand, eternal: What is a building? What is a city?

Urban sprawl and city compactness. A proposal for regional sustainability indicators. Case study of the towns of Alcorcon and Majadahonda (Comunidad de Madrid, Spain)

The main contribution of this research paper is to display a range of figures and values which could help urban planners to quantify the urban phenomenon of sprawl. In this way, after a rigorous analysis and comparison between a scattered urban fabric (Majadahonda) and a compact urban fabric (Alcorcón), several possible indexes are established and characterized in order to verify the main hypothesis: in what extent land consumption and exploitation of energy resources are higher in a scattered urban fabric than in a compact one.
