Therapeutic metaphors in engineering: how to cure a building structure

Cognitive linguistics have conscientiously pointed out the pervasiveness of conceptual mappings, particularly as conceptual blending and integration, that underlie language and that are unconsciously used in everyday speech (Fauconnier 1997, Fauconnier & Turner 2002; Rohrer 2007; Grady, Oakley & Coulson 1999). Moreover, as a further development of this work, there is a growing interest in research devoted to the conceptual mappings that make up specialized technical disciplines. Lakoff & Núñez 2000, for example, have produced a major breakthrough on the understanding of concepts in mathematics, through conceptual metaphor and as a result not of purely abstract concepts but rather of embodiment. On the engineering and architecture front, analyses on the use of metaphor, blending and categorization in English and Spanish have likewise appeared in recent times (Úbeda 2001, Roldán 1999, Caballero 2003a, 2003b, Roldán & Ubeda 2006, Roldán & Protasenia 2007). The present paper seeks to show a number of significant conceptual mappings underlying the language of architecture and civil engineering that seem to shape the way engineers and architects communicate. In order to work with a significant segment of linguistic expressions in this field, a corpus taken from a widely used technical Spanish engineering journal article was collected and analysed. The examination of the data obtained indicates that many tokens make a direct reference to therapeutic conceptual mappings, highlighting medical domains such as diagnosing,treating and curing. Hence, the paper illustrates how this notion is instantiated by the corresponding bodily conceptual integration. In addition, we wish to underline the function of visual metaphors in the world of modern architecture by evoking parts of human or animal anatomy, and how this is visibly noticeable in contemporary buildings and public works structures.

Desmaterialización de la envolvente estructural contemporánea : una secuencia de estrategias arquitectónicas en Toyo Ito, Herzog&de Meuron y Sanaa

La Tesis investiga aquellas obras en las que se ha producido un desplazamiento de la estructura portante hacia el perímetro del edificio para alcanzar su posterior desvanecimiento aplicando ciertos mecanismos arquitectónicos. En el proceso de la investigación se ha detectado cómo la rotundidad e inmediatez de la huella de lo estructural percibida en la arquitectura tradicional, tiende a desvanecerse, su desmaterialización queda patente en ciertas obras de la arquitectura contemporánea. La investigación comienza con la concordancia hallada entre tres edificios contemporáneos cuyo perímetro lo conforma una Envolvente Estructural: la tienda TODS, de Toyo Ito (2003); PRADA, de Herzog&de Meuron (2000) y DIOR, de SANAA (2001). Tres obras de fechas consecutivas, que, aun respondiendo a las mismas condiciones de ubicación, Omotesando (Tokio), uso, volumetría, altura y superficie, su Envolvente se configura de modo muy diverso, produciendo soluciones estructurales diferenciadas y heterogéneas. De estos tres modos de configurarse la envolvente, se desprenden las tres estrategias arquitectónicas empleadas en el desarrollo de la Tesis: figuración, abstracción y desmaterialización. Así pues, la investigación descubre, por una parte, un procedimiento figurativo que pone el acento en valores expresivos empleando códigos de significado como son los objetos de la naturaleza; por otra parte, un procedimiento abstracto, priorizando las reglas de construcción formal del propio objeto; y por último, como continuación de los anteriores, se descubre un procedimiento de desmaterialización planteado desde la delgadez de los muros, los materiales efímeros o una semitransparencia que pretende mayor conexión con el mundo exterior. Con el análisis de estas tres categorías secuenciales desveladas por los edificios citados de Omotesando, se han identificado otras obras clarividentes de Toyo Ito, Herzog&de Meuron y SANAA, por ser representativos de dichas nociones. Así pues, se han seleccionado veinticuatro casos de estudio y se han ordenado formando una colección de obras capaz de llegar a formular por sí misma un enunciado conclusivo sobre los procedimientos arquitectónicos capaces de velar la estructura mecánica. En la actualidad, el planteamiento de la Envolvente Estructural recurre a un nuevo modo de abordar la arquitectura. Esta ya no consiste en el juego sabio, correcto y magnífico, sino que adquiere una nueva dimensión poética desde la ausencia de la esencia resistente. Efectivamente, por un lado, se ha afirmado que ‘sin estructura no hay arquitectura’; y por otro lado, se trata de hacerla desaparecer. Así queda expresado en palabras de SANAA: “Para nosotros la estructura es muy importante, incluso su desaparición lo es”. Por otro lado, la Envolvente Estructural analizada en la Tesis recoge el legado de la historia, lo interpreta y se manifiesta con el lenguaje contemporáneo manteniendo aquella unidad entre las disciplinas de arquitectura e ingeniería comenzada en el siglo XIX. El contorno edilicio, conformado en un único elemento compacto e indiferenciado, resuelve diversas funciones habitualmente asignadas a otros elementos específicos: Encierra en un reducido espesor el cerramiento, la estructura resistente, el ornamento y el acondicionamiento térmico (en algunos casos); configura la forma arquitectónica y envuelve el espacio arquitectónico mostrando una libertad formal (cáscaras esculturales) y un lenguaje de liviandad (muros de espesores reducidos) sin precedentes. La tipología planteada condensa todo aquello que le permite expresar el enunciado más inmaterial de la estructura mecánica. Concluyendo, la Tesis verifica que una parte de la arquitectura contemporánea ya ha pasado del límite denso, corporeizado y mecánico tradicional, a un límite borroso, que se ha erosionado, se ha transmutado hasta su desmaterialización, su desvanecimiento o incluso su desaparición. ABSTRACT This thesis researches those buildings where the bearing structure has been moved towards the perimeter in order to reach its fading by means of architectural strategies. In the research development it has been detected how the clearness and immediacy of the footprint of the structure as noticed in the traditional architecture, tends to vanish, its dematerialization remains patent in certain contemporary architecture works. The research begins with the agreement found in three contemporary buildings whose perimeter is shaped by a structural envelope: TODS shop, by Toyo Ito (2003); PRADA, by Herzog&de Meuron (2000) and DIOR, by SANAA (2001). Three works in consecutive dates, that share the placement conditions, Omotesando (Tokio), use, volume, height and area, but its envelope is shaped in various ways, generating different and heterogeneous structural solutions. From these three ways of the envelope shape are deduced the three architectural strategies studied during the Thesis development: figuration, abstraction and dematerialization. Thus, the research discovers, on one hand, a figurative procedure that highlights the expressive values by using meaning codes such as the nature objects; on the other hand, an abstract procedure, prioritizing the formal construction rules typical of the object; at last, as a continuation of the others, a dematerialization procedure is shown, set out from the wall thinness, the ephemeral materials or the semitransparency that tries to increase the connection with the world around. With the analysis of these three categories in a sequence, shown in the Ometesando buildings, other works from Toyo Ito, Herzog&de Meuron and SANNAA have been identified because of being representative of those concepts. Therefore, twenty four case studies have been selected and have been ordered to set a collection of works that are able to formulate by themselves a conclusive statement about the architectural procedures that are able to veil the mechanical structure. Nowadays, the Structural envelope approach leads to a new way of dealing with architecture. This is not any more a wise game, correct and magnificent, but it acquires a new poetic dimension from the absence of the resistant essence. Indeed, on the one hand, it has been stated that ‘without structure there is no architecture’; and on the other hand, it tries to make it disappear. It is so stated in SANAA words: ‘The structure is very important for us, and even its disappearance” On the other hand, the Structural envelope analysed in this Thesis gathers the legacy of history, interprets it and it is expressed with a contemporary language, by keeping that unity between disciplines of architecture and engineering already started in the XIX century. The building boundary, shaped as a compacted and undifferentiated single element, solves several functions commonly assigned to other specific elements: keeps in a small thickness the envelope, the bearing structure, the ornament and the thermal conditioning (in same cases); it shapes the architectural form and envelopes the architectural space by showing a formal freedom (sculptural shells) and a lightness language (small thickness walls) with no precedents. This typology gathers all what lets to express the most immaterial statement of the mechanical structure. As a conclusion, the Thesis verifies that a part of the contemporary architecture has already gone over the dense limit, shaped and mechanical traditional to a blur limit that has been eroded, it has been changed until its dematerialization, its fading or event its disappearance.

Casas de la oligarquía castellana en la Granada del siglo XVI : tipologías, adaptación y contexto urbano, fundamentos para su recuperación

El tema de estudio de esta tesis es el análisis morfológico y cronológico de diez ejemplares emblemáticos de la arquitectura doméstica señorial de la Granada del siglo XVI, analizados en comparación con otros casos de referencia construidos en el mismo período en la propia ciudad, conservados y desaparecidos. También se han tenido en cuenta las principales manifestaciones arquitectónicas de los mayores focos urbanos contemporáneos en el reino de Castilla. El trabajo se ha desarrollado partiendo de la realización de una planimetría precisa y completa de las diez casas documentadas, uniendo al trabajo in situ sobre los datos materiales el estudio de las fuentes de archivo y de la bibliografía especializada existente sobre la materia. El análisis formal de las unidades domésticas ha sido enfocado al estudio tipológico de lo construido, haciendo especial hincapié en las pervivencias andalusíes sobre las cuales los nuevos moradores edificaron o adaptaron sus casas solariegas. En apoyo a las hipótesis presentadas se aporta la documentación arqueológica derivada de las excavaciones realizadas en los solares de las viviendas objeto de análisis, además de los planos de los estados previos a las recientes reformas sufridas por muchos de estos edificios. El análisis comparativo con algunos edificios contemporáneos en los que se ha documentado y estudiado cronológicamente su evolución histórica, ha permitido afianzar las hipótesis de datación y de reconstrucción de la distribución espacial de las fábricas originarias de la época tratada. Los objetivos de la investigación han sido orientados a poner de manifiesto la delicada y compleja transición de la medina nazarí a la ciudad cristiana, tratando también ciertas características multiculturales propias de las técnicas constructivas y de sociedad de la época. Los resultados de este estudio multidisciplinar se han registrado en un mapa de datos creado con el Sistema de Información Geográfico, en el que se han incluido tanto los datos cronológicos como formales, individualizando los ambientes que constituyen las pervivencias medievales y los que se han construido después, aportando sus distintas dataciones. Se ha querido dar respuesta a varios interrogativos: ¿Cómo se adapta la arquitectura castellana al tejido urbano andalusí? ¿Reaprovecha las preexistencias o las elimina en cada momento? ¿De qué modo la ciudad ha ido modificándose hasta configurarse como una ciudad moderna? ¿Cuánto se ha mantenido este patrimonio de casas? ¿Cómo se debería conservar? Se ha tratado de resolver estas cuestiones formulando síntesis gráficas en las que se puede comprender la evolución histórica de las viviendas acontecida a lo largo del siglo XVI, junto con sus transformaciones recientes provocadas por las intervenciones contemporáneas. Asimismo se aporta el estudio de las principales características de las intervenciones acometidas sobre este patrimonio único de viviendas, que por su propia naturaleza es altamente perecedero y necesita que se formulen criterios eficaces y correctos para su mayor conservación. El punto de partida de este trabajo no ha sido solamente el análisis de campo sino también la recopilación y ordenación de los datos procedentes de la bibliografía existente para formular discursos coherentes y precisos sobre la evolución de este tipo de viviendas históricas, cuyos valores son tan expuestos a graves deterioros que su catalogación, documentación y valoración se hacen imprescindibles. Pese a que las diez viviendas incluidas en los capítulos de estudio detallado estén catalogadas en los Planes Especiales de Protección (Albaicín, 1990 y Centro, 2002), sus caracteres formales y sus elementos estructurales y decorativos de valor histórico han sufrido un evidente proceso de expolio o destrucción, hecho grave que esta Tesis quiere reflejar de cara a la deseable futura puesta en valor real de estos edificios así como, indirectamente, de sus ámbitos urbanísticos de pertenencia. ABSTRACT The purpose of this thesis is to study the morphological and chronological characteristics of ten emblematic mansions belonging to the architectural period of the 16th Century in Granada, Spain. These houses are compared with other similar outstanding constructions of the same period that are located in the city, which have either been preserved or disappeared. Also, this study has taken into account the main architectural expressions of greater contemporary urban areas of the Kingdom of Castile. The work carried out began, first of all, by drawing a precise and thorough planimetry of the ten surveyed houses, together with in situ tasks based on physical data, a study of archival data, and the specialized existing bibliography on the subject. The formal analysis of the home units is focused as a typological study of erected buildings, with a special attention on Al Andalus remains over which the new householders constructed or adapted their mansions. The hypotheses brought forward have been supported by the archaeological documentation that had been elaborated during the excavation works of the houses concerned in this study. Moreover, the drawings of the states of the sites, previously to the most recent renovation works many of these buildings have undergone, have been presented. The comparative analysis made with some contemporary buildings, which have been chronologically documented and studied in their historical evolution, has confirmed the dating hypotheses, and that of the reconstruction of the spatial distribution of the original factories the period discussed. The aims of this research have been oriented to bring to light the delicate and complex transition of the town, from the Nasrid period to Christian times. The research has also dealt with some special multicultural characteristics of the constructive techniques, as well as of the society of that period. The results of this multidisciplinary study have been registered on a data map created with the Geographical Information System, which includes both the chronological and formal data. The Medieval settings, and those of later constructions, have been individualised and dated. Several questions have been answered: how the Castilian architecture adapts to the Al Andalus urban design? Have the pre-existing structures been reused or eliminated at each stage? How has the town evolved until becoming a modern city? To which degree this heritage of houses has remained? How should it been preserved? These questions have been approached by means of graphical syntheses in an attempt to bring an understanding of the historical evolution of the houses throughout the 16th Century. But also, this work shows the more recent transformations these structures suffered over the contemporary period. Moreover, there is a study of the main characteristics of interventions over this unique patrimony of housing which by nature is perishable and needs a formulation of correct and efficient criteria for better conservation. The starting point of this work has not only been that of field analysis, but also the gathering and ordering of the existing bibliographical data, in order to formulate coherent and precise statements on the evolution of this type of historical housing. Its treasures are so exposed to severe deterioration that their cataloguing, documentation and appreciation are becoming crucial. Despite the fact that the ten houses considered in the chapters of this detailed study are listed in the special protection plans (Planes Especiales de Protección, Albaicín plan of 1990 and the town centre plan of 2002) their formal characteristics, as well as structural and decorative historical value, have suffered gradual plunders or destruction. This thesis tries to reflect how serious is that matter and the need in the future to give this heritage and the surrounding urban environment, a real value.

Clichy-Batignolles, Paris: a case of successful inner-city regeneration

The third issue of the column deals with the regeneration of inner-city rail station areas. The successful case of Gare Saint-Lazare in Paris is analyzed by Giulio Verdini, an architect and urban planner based in China and Paris. The quality of this recent project is evident at different levels: as an innovative experiment of planning with public consultation, as a new mixed-used neighbourhood organized around a beautiful park, as a collection of interesting contemporary buildings promoted through open architecture competitions. The memory of the old rails has been interpreted as an occasion for creating significant urban connections, and the city of Paris demonstrated again and again its rare capacity to regenerate itself. 内城火车站区域的更新历来不是件轻松的工作,这在1990年代以来诸多的欧洲城市中都已经得到印证.伦敦的国王十字车站和柏林的中央火车站区域都是著名的更新案例,此外还有鹿特丹和斯图加特中央火车站这些争议性的案例,它们都表明了这个更新过程有多么复杂而难料.其原因包括众多相互角力的私人及公众影响、改造带来的未知花费及收益,以及市民群体在其中扮演的越来越重要的角色.这个位于巴黎17区的克里希·巴蒂涅奥勒开发区更新项目同样如此.不过,随着项目的建造渐入佳境,我们愈发可以看出,它很可能会成为欧洲内城最成功的更新案例之一.这篇简要介绍的目的就是勾勒出这一成功案例背后的构思和动机,以展现这个理应矛盾重重而得到未充分利用的地段如何成为让巴黎西北区改头换面的良机.

The impacts of power outages on the residents of contemporary multistorey apartment buildings in subtropical environments

With significant population growth experienced in South East Queensland over the past two decades and a high rate of growth expected to continue in coming decades, the Queensland Government is promoting urban consolidation planning policies to manage growth sustainably. Multi-residential buildings will play an important role in facilitating the increased densities which urban consolidation policies imply. However, a major flood event in January 2011 has brought to light the vulnerability of certain types of multi-residential typologies to power outages. The crisis conditions exposed how contemporary building design and construction practices, coupled with regulatory and planning issues, appear to have compromised the resilience and habitability of multi-storey residential buildings. In the greater urban area of Brisbane, Queensland, the debilitating dependence that certain types of apartment buildings have on mains electricity was highlighted by residents’ experiences of the Brisbane River flood disaster, before, during and after the event. This research examined high density residential buildings in West End, Brisbane, an inner city suburb which was severely affected by the flood and is earmarked for significant urban densification under the Brisbane City Plan. Medium-to-high-density residential buildings in the suburb were mapped in flooded and non-flooded locations and a database containing information about the buildings was created. Parameters included date of construction, number of storeys, systems of access and circulation, and potential for access to natural light and ventilation for habitable areas. A series of semi-structured interviews were conducted with residents involved in the owners’ management committees of several buildings to verify information the mapping could not provide. The interviews identified a number of critical systems failures due to power outage which had a significant impact on residents’ wellbeing, comfort and safety. Building services such as lifts, running water, fire alarms, security systems and air-conditioning ceased to operate when power was disconnected to neighbourhoods and buildings in anticipation of rising flood waters. Lack of access to buildings and dwellings, lack of safety, lack of building security, and lack of thermal comfort affected many residents whether or not their buildings were actually subjected to inundation, with some buildings rendered uninhabitable for a prolonged period. The extent of the impact on residents was dramatically influenced by the scale and type of building inhabited, with those dwelling in buildings under a 25m height limit, with a single lift, found to be most affected. The energy-dependency and strong trend of increasing power demands of high-rise buildings is well-documented. Extended electricity outages such as the one brought about by the 2011 flood in Queensland are likely to happen more frequently than the 50-year average of the flood event itself. Electricity blackouts can result from a number of man-made or natural causes, including shortages caused by demand exceeding supply. This paper highlights the vulnerability of energy-dependent buildings to power outages and investigates options for energy security for occupants of multi-storey buildings and makes recommendations to increase resilience and general liveability in multi-residential buildings in the subtropics through design modifications.

LCADesign : an integrated approach to automatic eco-efficiency assessment of commercial buildings

Buildings consume resources and energy, contribute to pollution of our air, water and soil, impact the health and well-being of populations and constitute an important part of the built environment in which we live. The ability to assess their design with a view to reducing that impact automatically from their 3D CAD representations enables building design professionals to make informed decisions on the environmental impact of building structures. Contemporary 3D object-oriented CAD files contain a wealth of building information. LCADesign has been designed as a fully integrated approach for automated eco-efficiency assessment of commercial buildings direct from 3D CAD. LCADesign accesses the 3D CAD detail through Industry Foundation Classes (IFCs) - the international standard file format for defining architectural and constructional CAD graphic data as 3D real-world objects - to permit construction professionals to interrogate these intelligent drawing objects for analysis of the performance of a design. The automated take-off provides quantities of all building components whose specific production processes, logistics and raw material inputs, where necessary, are identified to calculate a complete list of quantities for all products such as concrete, steel, timber, plastic etc and combines this information with the life cycle inventory database, to estimate key internationally recognised environmental indicators such as CML, EPS and Eco-indicator 99. This paper outlines the key modules of LCADesign and their role in delivering an automated eco-efficiency assessment for commercial buildings.

Overview of design concepts of traditional Iranian architecture and its reflections in Iranian contemporary architecture

This article has attempted to investigate the patterns of traditional architecture in Iran's warm and dry climate and whether these patterns have been attended to in Iran's contemporary architecture or not. Since the two elements of culture and climate are much significant in Iran's traditional constructions, this article aimed at dealing with subjects such as the causes of the shapes of traditional buildings in Iran's warm and dry climate in constructions like houses, schools, mosques and bazaars, and why they were constructed in those shapes, and also considering their patterns in these places in the light of cultural and climatic aspects, and their cultural and climatic relationships and investigating cultural-climatic causes of the directions and situations designed for the spaces present in these buildings and finally it is intended to classify the conceptual patterns of the traditional architecture of Iran's warm and dry climate. The article is going to consider the amount of using these patterns in Iran's contemporary architecture. The study has been conducted using library and field method.

Inside out: Why do so many great buildings have drab interiors?

An extravaganza of shapes now forms our city skylines. CAD and BIM with their inbuilt links to manufacturing and construction processes has made possible this kind of effusive architectural expression, at least externally. Building developers clearly understand the enormous marketing potential for impact expression. The skilled manipulation of 3D CAD software enables architects to achieve usable gross floor space within an enticingly sinuous, but build-able, envelope. This critical factor is resulting in a fundamental change to the appearance of our cities. It has become plausible, at least, to design and build complex and non-repetitive buildings without incurring prohibitive additional labor costs.However The ground level lobby spaces often do manage to retain some of the external. However, the interior working spaces, particularly in commercial office buildings tend to loose this grand gesture. However - the internal activity - the very reason for the existence of the building – often takes place in monotonous spaces that seem driven predominately by the need to accommodate workstation furniture and functions in dire need of reconsideration.

Transgressing Contemporary Boundaries:The Narrator as True Custodian of Cultural Knowledge in Ulster Society

Historically in Gaelic culture, the bard was greatly valued and admired as an important and integral part of society. Travelled, schooled and specifically trained in their art, the bard helped ensure identity and reassurance for Gaelic families by grounding them both temporarily and spatially into their landscape. Entrusted with the duty and responsibility of recording place and event, the bards worked without writing and by transgressing man-made boundaries, travelled throughout the land weaving their histories into the very fabric of society.

Now no longer with us, we find ourselves without the distinguished chronicler to undertake this duty. Yet the responsibility of the Gaelic bard is one still shared by all artists today; to facilitate memory and identity, whether good or bad. Many Ulster writers, by happenstance and geography have found themselves located in a place of painful histories. An immediate difficulty for those local writers becomes manifest by being intrinsically implicated into those histories – whilst having first-hand knowledge and comprehension beyond that of the outsider, the local writer is automatically damned by association and relationship, thereby tarnishing their voice in comparison to the perceived impartiality of others.
Some writers however have successfully sought ways to escape this limitation and have worked in ways that can transgress the restrictions of prejudgement. John Hewitt, by purposely becoming a self-imposed tourist was able to distance himself to write impartially about the past, recognising that ’the place without its ghosts is a barren place.’1 In ‘The Colony’,2 tradition, peoples and mapping of the land are all narrated by Hewitt in a similar way to the Gaelic bardic topographic poems of Sean O'Dubhagain and Giolla Na Naomh O'Huidhrin3 in compiling a rich cultural atlas.

Similarly the Belfast poet and novelist Ciaran Carson also writes and records the city from an intermediary position; that of translator. Mediating between reader and aisling,4 Carson himself takes the reader on a journey into name, meaning, time and place, focusing primarily on the city of Belfast, familiar in name but impenetrable in depth to most.

Furthermore, this once-forgotten tradition to chronicle is now being continued by the new breed of Irish crime writers where the likes of Brian McGilloway, Stuart Neville and Adrian McKinty can, by way of the crime novel, accurately record contemporary society. Thus, ghost estates, listed buildings, archaeological digs, street and city have all provided setting and subject matter for recent novels. Moreover by choosing the ‘outsider from within’ as their chief protagonist, whether detective or criminal, each author is able to transgress the boundaries of prejudice and preconception that hinder genuine understanding and knowledge.

Looking in turn at the Gaelic bard, the twentieth century Ulster poet and the new breed of Irish crime writer, the authors will outline the real value of the narrator, by being able to act as cultural transgressor beyond the seeming and alleged as the true chronicler in society, and then with specific reference to city and countryside in Ireland, as a valuable custodian of knowledge in architecture and place.

An approach to compatible new buildings in historic urban environments : case study in the Arabian Gulf region

Cette thèse contribue à l'état actuel des connaissances sur la compatibilité des nouveaux bâtiments avec les environnements urbains historiques. Elle suit un mode de présentation classique: Introduction, Revue de Littérature, Méthodologie, Résultats, Discussion et Conclusion. Le problème étudié est le manque d'orientation pour intégrer les processus de développement et de sauvegarde dans les contextes établis. La littérature récente révèle que les règles de préservation, aussi appelées normes et lignes directrices, ne peuvent pas garantir une relation compatible entre une intervention et son milieu. La pensée contemporaine dans le domaine de la conservation et de la gestion du patrimoine invite donc l’exploration d'autres moyens pour lier la nouvelle architecture à l'ancienne. Ainsi, le présent projet de recherche explore une approche alternative aux règles de préservation en vue d’atteindre le but de nouveaux bâtiments compatibles et d’améliorer la prise de décision fondée sur les valeurs. Pour produire des résultats spécifiques et convaincants, un cas a été sélectionné. Celui-ci est une ville dans la région du Golfe Arabe : la Ville de Koweït. Le résultat principal est le développement d’une approche, mise en œuvre en posant des questions approfondies sur le lieu, la conception et la construction des nouveaux bâtiments. Les questions suggérées dans la thèse mettent l’accent sur les valeurs patrimoniales et les choix de conception afin de permettre un changement réfléchi au sein des environnements urbains historiques. Elles aident aussi à évaluer les nouvelles propositions de projets au cas par cas. Pour démontrer comment cette approche pourrait être présentée et utilisée par les requérants et les évaluateurs, un modèle théorique est proposé. Ce modèle a ensuite été discuté avec des professionnels locaux et internationaux qui ont identifié ses forces et ses limites. En conclusion, l’ensemble des résultats montre que la mise à disposition de règles et / ou de questions approfondies n’est pas une solution satisfaisante puisqu’il y a d'autres enjeux importants qui devraient être abordés: comment appliquer l'orientation efficacement une fois qu’elle a été créée, comment développer la compétence liée à la prise de décision fondée sur les valeurs et comment insérer la conservation du patrimoine dans la mentalité du gouvernement local et des communautés. Lorsque ces enjeux seront traités, le patrimoine pourra devenir partie intégrante du processus de planification, ce qui est le but ultime. Enfin, cinq axes de recherche sont recommandés pour poursuivre l’exploration des idées introduites dans cette étude.

Procesos configurativos: de la trama a la noción de campo en los "mat buildings"

La presente tesis aborda el estudio sobre los llamados mat buildings, que surgen entre los años cincuenta y sesenta del pasado siglo. Los mat buildings, también llamados “edificios esteras” o “edificios alfombras”, nacen en gran parte como consecuencia de los desacuerdos e insatisfacciones de los CIAM con el reduccionismo funcionalista y los principios de compartimentación funcional. Estos nuevos modelos remplazan el modelo de ciudad entendido como una colección de edificios individuales por una concepción de un patrón urbano. No es la suma de la longitud, la altura y el ancho sino más bien una densa alfombra bi-dimensional, con una configuración de formas que ofrece al mismo tiempo un orden repetitivo y una infinita diversidad de secuencias con infinitas posibilidades de adaptación donde el hombre vive y se desplaza. Estas características que irán apareciendo en la obras de muchos de los arquitectos que forman parte del grupo Team X son los que Alison Smithson empieza a revelar en su artículo, con la ambición de manifestar una nueva sensibilidad y una nueva forma de entender y ver la arquitectura. Los mat buildings y los cluster serán los códigos utilizados por diferentes miembros del Team X para pensar una arquitectura y un urbanismo alternativo al propuesto por los CIAM. Mediante ellos encuentran el camino para una nueva estética de la conexión con un desplazamiento desde una concepción determinista de la forma arquitectónica (una forma cerrada y en general definida a priori) hacia una actitud más libre, más abierta, fundamentada no tanto en la entereza de la forma global sino en cuanto a la intensidad de sus redes internas y de sus diferentes niveles de asociación. La tesis tiene como propósito final cuestionar si esta tipología de edificios, cuyo principio de base es siempre una matriz geométrica abierta (trama, retícula, malla), con crecimiento ilimitado, puede redefinir la frontera entre ciudad y edificio y, por tanto, entre público y privado, individual y colectivo, estructural e infraestructural, permanente y variable. Por ello, se presenta un estudio histórico y crítico en profundidad sobre los mat buildings, analizando detenidamente y por orden cronológico cinco de sus obras más paradigmáticas: el Orfanato en Ámsterdam de Aldo Van Eyck, la Universidad Libre en Berlín de Candilis, Josic y Woods, el Hospital de Venecia de Le Corbusier y Guillermo Jullián de la Fuente, el edificio administrativo de la Centraal Beheer en Apeldoorn de Herman Hertzberger, y por último el MUSAC en León, realizado por Mansilla y Tuñon. Las cuatro primeras obras pertenecen al periodo Team X y son precursoras de muchos otros proyectos que aparecerán a posteriori. La última obra analizada, el MUSAC, es estudiada conjuntamente con algunas obras del arquitecto japonés Sou Fujimoto y otros casos contemporáneos con la intención de manifestar cómo arquitectos de horizontes muy diferentes vuelven a recurrir a estos modelos de crecimientos ilimitados. Mediante el estudio de varios ejemplos contemporáneos se examinan las repercusiones, transformaciones y evoluciones que estos modelos han tenido. La exploración contrastada permite apreciar adecuadamente la pertinencia de estos modelos y los cambios de modalidades y de procesos que advienen con la aparición en el panorama contemporáneo de la noción de campo y los cambios de paradigma que conlleva. Estos nuevos modelos abren nuevos procesos y forma de abordar la arquitectura basada en las relaciones, flujos, movimientos y asociaciones que son caracterizados por diferentes patrones que vienen a alimentar todo el proceso del proyecto arquitectónico. El estudio de estos nuevos modelos nos indica las cualidades que puede ofrecer la revisión de estos métodos para empezar a tratar nuevas cuestiones que hoy en día parecen ser, permanentemente, parte de la condición urbana. XII ABSTRACT This thesis deals with the study of the so-called mat buildings which emerged between the fifties and sixties of the last century. Mat, or carpet, buildings appeared largely as a result of the CIAM’s disagreement and dissatisfaction with functionalist reductionism and the principles of functional compartmentalisation. These new models replaced the model of the city, seen as a collection of individual buildings, with the concept of an urban pattern. It is not the sum of the length, height and width but rather a dense, two- dimensional mat with a configuration of forms offering both a repetitive order and an infinite diversity of sequences with endless possibilities for adaptation, where man lives and circulates. These characteristics, which appeared in the works of many of the architects who formed part of Team X, are those that Alison Smithson started to reveal in her article with the aim of manifesting a new sensibility and a new way of understanding and seeing architecture. Mat buildings and clusters were the codes used by different members of Team X to plan an alternative architecture and urbanism to that proposed by the CIAM. With them, they found the path for a new aesthetic of connection, with a shift from a deterministic concept of the architectural form (closed and generally defined a priori) towards a more free, more open attitude based not so much on the integrity of the overall form but on the intensity of its internal networks and different levels of association. The end purpose of this thesis is to question whether this type of building, the basic principle of which is always an open geometric matrix (grid, recticle, network) with unlimited growth, can redefine the boundary between city and building and, thus, between public and private, individual and collective, structural and infrastructural, and permanent and variable. To this end, an in-depth historical and critical study of mat buildings is presented, analysing carefully and in chronological order five of the most paradigmatic works of this style: the Orphanage in Amsterdam, by Aldo Van Eyck; the Free University of Berlin, by Candilis, Josic and Woods; Venice Hospital, by Le Corbusier and Guillermo Jullián de la Fuente; the Centraal Beheer administration building in Apeldoorn, by Herman Hertzberger; and lastly, the MUSAC (Contemporary Art Museum) in León, designed by Mansilla and Tuñon. The first four works are from the Team X period and were the precursors to many other projects that would appear later. The last work analysed, the MUSAC, is studied together with some works by Japanese architect Sou Fujimoto and other contemporary cases to show how architects with very different perspectives revert to these models of limitless growth. Through the study of several contemporary examples we examine the repercussions, transformations and evolutions these models have had. The contrasted research XIII allows us to properly appreciate the importance of these models and the changes in forms and processes that came with the emergence of the idea of field in the contemporary arena and the paradigm shifts it entailed. These new models opened up new processes and a way of approaching architecture based on relationships, flows, movements and associations characterised by different patterns that feed the entire process of the architectural project. The study of these new models shows us the benefits that a review of these methods can contribute to addressing new issues that today appear to be a permanent part of the urban condition.
