Underground dwellings in the Tajuña valley, Madrid, Spain and their bioclimatic adaptation

Underground dwellings are the maximum example of the vernacular architecture adaptation to the climatic conditions in areas with high annual and daily thermal fluctuations. This paper summarizes the systematic research about the energy performance of this popular architecture and their adaptation to the outdoor conditions in the case of the low area of the River Tajuña and its surroundings. Some considerations on their maintenance and renovation arise from the research.

La modernidad paradigmática de la arquitectura popular. Orígenes y evolución de su descubrimiento en las publicaciones periódicas de arquitectura en España 1897-1958

La aparición de la arquitectura popular en la escena de la cultura arquitectónica siempre ha estado rodeada de escasa claridad, especialmente si se trata de determinar las circunstancias en que apareció el interés por ella o la primera vez que fue mostrada en alguna publicación. El origen de la estimación de la arquitectura popular como tal se presenta en principio envuelto en una nebulosa, difuminado por la suposición de un siempre anterior conocimiento de ella -por la obviedad de este fenómeno-, y por la escasa atención prestada al tema, a lo que hay que sumar los desconcertantes indicios de que en realidad sólo ha sido apreciada en tiempos más recientes. Este estudio intenta arrojar luz sobre ese momento en que la arquitectura popular es descubierta, reconocida y difundida, y posteriormente estudiada con detenimiento hasta que llega a adquirir el status que le corresponde, en el ámbito del territorio español. La arquitectura popular no aparece en un momento determinado, como cualquier tendencia en la evolución de cierta sensibilidad estética o movimiento. La arquitectura popular siempre ha estado ahí. Lo único que cambia, y que permite que de repente la arquitectura popular sea tenida en cuenta, es la mirada de quien la descubre, la valora, la estudia o la propone como fenómeno digno de la atención y la estimación de los arquitectos. Así pues, la interpretación de la arquitectura popular como una forma más de las distintas que adopta la arquitectura como manifestación técnica y artística, plenamente aceptada dentro la concepción vigente de la época, es la historia de las miradas que se han dirigido a ella, de las distintas sensibilidades que han reparado en ella y de las tendencias arquitectónicas, construidas o teóricas, que han acudido a ella como fuente de inspiración o como modelo de virtudes constructivas o proyectuales. Desde este punto de vista se hace necesario investigar en las diferentes etapas de la modernidad en España, en sus acontecimientos, sus discursos, y sus obras construidas, partiendo de las distintas mentalidades que las sustentaron, para de este modo profundizar en la trayectoria seguida a través del tiempo histórico y del espacio geográfico en que se han desarrollado esas miradas. Para ello se ha realizado un estudio de las publicaciones periódicas de arquitectura españolas como elementos susceptibles de proporcionar la información más fidedigna posible sobre el interés en la difusión, el debate y la reflexión arquitectónica en torno a este fenómeno de la arquitectura popular. Es conocido el inestimable valor de las revistas como transmisoras no sólo de los acontecimientos de actualidad –la arquitectura popular no es uno de ellos- sino de la opinión y la forma de pensar de la intelectualidad del mundo de la ciencia y del arte, de los arquitectos en sus distintas actividades –profesional, docente, teórica, directiva, artística- y de las instituciones y personajes vinculadas al mundo de la arquitectura y la edificación. Es además relevante el hecho de que proporcionan una visión inmejorable de la época en que se publican, con datos importantes de carácter social, cultural, político o económico, que facilitan el encuadre de los acontecimientos estudiados en su contexto histórico y permiten un acercamiento a éstos de una forma más afinada. ABSTRACT Vernacular architecture’s appearance in the architectural culture’s scene has always been involved by certain obscureness, specially if the task is to know the circumstances of its first appealing, or the first time that was published. Original vernacular architecture’s valuation in its own seems to be involved in a vague nebula, blurred by the supposed fact of an always previous and obvious knowledge, and the scarce attention kept over this theme, increased in confusion when considering some last traces showing that only in recent times it has been really appreciated. This work searches for clarity inquiring those moments in which vernacular architecture is discovered, then recognised and issued, and finally broadly studied till reaches the status that has today. This investigation is focused on the spanish context. Vernacular architecture does not come out at a certain moment, as any artistic or stylish trend; it has always been there. The only thing that changes, and suddenly makes vernacular architecture take place in architects’ mind, is the observer’s glance, who discovers it and takes care about it, studying and proposing it as a worthy architectonic phenomenon that deserves architect’s attention. Thus, vernacular architecture’s interpretation, as another one of the several forms of conceiving architecture as a technical and artistic expression, fully accepted in the spirit of its time, is the story of the glances that have focused on it, the story of the varied sensibilities that have felt concerned with it, and the story of theoretical or practical trends that gaze it as an inspiration’s source or a model for functional or designing values. From this point of view is necessary to dive into the different ages of modernity, their events, their programs, and their built architecture, departing from the different attitudes developing in the historic time and the geographic space of Spain. With this purpose it has been realized this study on spanish periodical journalism specialized in architecture, searching for the most reliable information possible, due to their attention to teorethical discussion, critique, and thoughts about the fact of vernacular architecture. Is well known the value of architecture magazines as excellent diffusers, not only of hot news –vernacular architecture is not one of them- , but also of intellectual activity in science and art, of the architects in their different activities –professional, academic, theoretical, executive, artistic- and of outstanding people and Institutions linked with architecture and building. Is also remarkable the fact that they provide an unbeatable vision of the whole world in the moment they appear, bringing at the same time significant information about social, cultural, political or economic nature, that make easier the understanding of the historical context, in a more fitting way.

Una arquitectura en el territorio. Naturaleza de los tipos de la edificación vernácula española: la casa tradicional soriana

La presente Tesis Doctoral trata de ofrecer el primer estudio monográfico global que se dedica a cierta arquitectura vernácula, de un territorio situado en el centro–norte de la Península Ibérica. Asentada a horcajadas entre la Meseta septentrional castellana y la depresión mediterránea del río Ebro, y repartida en comarcas vinculadas a la España del norte y áreas de aspecto más meridional, la provincia de Soria presenta una notable superposición de tradiciones culturales, que se reúnen para generar desarrollos edificatorios diversos. En relación con esa variedad esencial, algunos datos contenidos en este trabajo, y muchos resultados de sus análisis, podrían extrapolarse, sin excesivos forzamientos, a fenómenos constructivos paralelos, correspondientes a amplias regiones del país. Tras enunciar brevemente las razones y objetivos de la investigación, junto con sus planteamientos de partida y determinados principios metodológicos, se han presentado unos elementos preliminares: apartados en los que se describe el medio físico y el marco humano, dentro de los cuales la arquitectura tradicional se desarrolla. Seguidamente, da comienzo la monografía referida a una realidad construida compleja, cuya explicación se ha dividido, por causas instrumentales, en dos partes diferenciadas. En el primer desarrollo, de género esencialmente analítico, se presentan los objetos edificados desde la perspectiva de la realidad material y constructiva de sus partes componentes; o desde el punto de vista de las técnicas que, en su día, sirvieron para definir elementos edificatorios, y sistemas generales de ellos. En la sección segunda, de naturaleza algo más sintética, se muestran otros aspectos de las arquitecturas, tomadas ya globalmente, o asociadas en grandes agrupaciones y conjuntos. Describiendo, de modo conciso, los territorios y ambientes urbanos tradicionales, en los que unos u otros tipos comparecen. Y pasando después a exponer, ya in extenso, los rasgos comunes o más específicos de estos y aquellos modelos arquitectónicos, así como sus recíprocas vinculaciones o procesos tipológicos corrientes. A modo de discusión final, se incluyen determinadas conclusiones, deducidas de cuanto se ha expuesto a lo largo del texto. Tales resultados, de índole algo más teórica, nos ayudan a comprender cuál es la efectiva naturaleza de los tipos individuados en las construcciones populares sorianas, particularmente en aquéllas de uso doméstico. Carácter compartido, sin duda, con otros modelos que, para territorios de mayor dimensión, podrían llegar a describirse. Así, el fenómeno constructivo referenciado se contempla, más allá de su concreto alcance local, como una muestra representativa de realidades más vastas, de orden real y también conceptual, que se regirían principios análogos. ABSTRACT The present Dissertation brings the first monographic study dedicated to certain vernacular architecture located in the territory of Soria, at the Center-North of the Iberian Peninsula. Seated between the Northern Castilian Plateau and the Ebro River Mediterranean Depression, and spread into regions linked to Northern Spain and areas of more southern characteristics, the province of Soria presents a remarkable overlap of cultural traditions providing several building developments. That essential variety is widely shown throughout this work, where the information recovered and the analysis’ reports allow a feasable extrapolation that explain the constructive phenomena all over broad regions of the Spanish country. After stating briefly the aim of the research and its background, along with its methodological process, this work starts its task introducing some preliminary elements: the physical environment and the human context where traditional architecture takes place. Afterwards the text focuses on the different vernacular constructions in all their complexity, which exposure has been divided in two parts: the first one, analytic, shows the built objects from the point of view of the materials and each constructive element; or, in another way, the constructive techniques that define building elements in the overall constructive systems. The second section, more synthetic, shows other aspects of this kind of architecture considering all cases, attempting to a theoretical classification and describing the territory and the urban environments where these architectures are placed. As follows, common and specific features of the architectural types studied are widely shown, as well as reciprocal connections, or typological processes underlying. The final discussion extracts conclusions that help us to understand the effective nature of the types found in Soria’s vernacular construction, particularly those for domestic use. There is no doubt that these buildings share a common character with another ones belonging to different territories of larger dimensions, that could be concisely studied in other place. Thus, these studied constructive phenomena can be considered, beyond the specific local scope, as a sample for more complex architectures, both in conceptual and physical terms, which seem to be guided by similar principles.

Antiguo Poblado de Algarrobito ubicado en el Valle del Elqui Chile, y su Patrón Urbano Bioclimático

La importancia de conocer bien el entorno para un proyecto arquitectónico es que podemos adaptarlo a nuestras necesidades fisiológicas de Confort Térmico. Podemos decir entonces que el edificio juega un papel fundamental como técnica de control de nuestro entorno. El edificio nos debería entregar un entorno controlado para que nos sintamos bien térmicamente, considerando además, que la arquitectura por sí misma puede lograr dicho confort la mayor parte de las veces. De no ser así, los usuarios tienden a colocar elementos mecánicos, para generar frío o calor artificialmente. Es fundamental entonces que nuestros edificios, tengan una correcta interacción con los recursos naturales del lugar para lograr dicho confort térmico. Pero lograr el Confort Térmico en todos los edificios de una ciudad como unidad, no logrará que la ciudad entera sea confortable térmicamente, ya que las complejas interacciones hacen que la problemática se deba enfrentar como algo sistémico. Esto quiere decir, que para que una ciudad o un conjunto logren la Confortabilidad Térmica deseada por sus habitantes debiera haber sido planificada conforme a variables urbanas que interactúen con el medio natural en forma eficiente. Con la observación de ciertos conjuntos habitacionales antiguos en el interior del Valle del Elqui, Chile y de sus relaciones entre variables urbanas y naturales, queda de manifiesto ciertas características que conllevan a pensar que existió una planificación ambiental en éstos que llevaron a lograr un conjunto con características bioclimáticas. Las evidencias de la existencia en primer lugar de un patrón urbanístico en dichos conjuntos habitacionales antiguos, hacen pensar que dicho patrón se trataría de un patrón bioclimático rural planificado, lo que hace que exista un gran interés por el estudio de estos conjuntos. Hasta ahora, en Chile, los pocos estudios de Confort Térmico que existen, están orientados a edificaciones aisladas, al Confort térmico interior de la edificación en el ámbito urbano, y en nada a Patrones Bioclimáticos de Conjuntos Habitacionales en una situación de ruralidad como a la referida en esta investigación. Además, los estudios referidos al clima urbano, difieren a los del clima rural, por lo que se necesitan mayores estudios aún para comprender mejor la problemática. Es por esto, que la mayoría de los casos mencionados en este estudio son contextualizados al ámbito urbano por carecer de otros estudios rurales. Es en este sentido que esta investigación cobra real importancia y pretende establecer la relación existente entre las variables morfológicas rurales y los recursos naturales del lugar y que generan un confort térmico ideal para sus habitantes, al mismo tiempo, se analiza la existencia de un Patrón Bioclimático en un poblado denominado Algarrobito ubicado en la cuenca del Valle del Elqui, Chile. Es en este sentido que el propósito principal de este trabajo es determinar la real existencia de un Patrón Bioclimático que relacione la morfología rural y edificada de los antiguos poblados pertenecientes a la cuenca del Valle de Elqui Chile con el microclima del lugar. La metodología empleada se basa en realizar primeramente el estudio del microclima del lugar a través de las Cartas Bioclimáticas. Para ello se obtuvo información de datos climatológicos de las estaciones meteorológicas ubicadas en la cuenca del Valle de Elqui, principalmente las más cercanas al lugar de estudio. Mediante una revisión exhaustiva de la información arquitectónica, así como de una labor de reconocimiento en terreno realizada en el poblado seleccionado y de la aplicación del Climograma local, se identificaron las diferentes zonas bioclimáticas del poblado antiguo y potenciales áreas de estudio en el conjunto. Esta actividad incluyó un estudio preliminar de la energía solar local, vientos, humedad, temperaturas y su interacción con el conjunto, permitiendo una primera aproximación a la problemática del espacio exterior y las viviendas. Esto permitió en base a las condicionantes del lugar, la arquitectura vernácula y los materiales descubrir un Patrón en el antiguo conjunto que permitía entregar confortabilidad térmica a sus habitantes y darse cuenta también, que el nuevo conjunto emplazado en el sector no seguía ese patrón con las disfuncionalidades que ello llevaba. Con esto quedó demostrado en primer lugar la existencia de un Patrón Bioclimático rural, los beneficios del patrón, la importancia de éste como causante de Confortabilidad Térmica del conjunto, y por ende de mejor eficiencia energética, así como también, que el nuevo conjunto no sigue para nada este Patrón, pero que existe también la posibilidad de rectificación y por supuesto, que los nuevos desarrollos residenciales del Valle del Elqui, puedan planificarse en base al patrón bioclimático descubierto. ABSTRACT Knowing the environment of an architectonic proyect is really important for adjusting it to our physiological needs of Thermal Comfort. So we can say that the building plays a key role as a technique of control of our environment. The building should give us a controlled environment to make us feel good thermally, and it usually can reach pleasurable temperatures by itself. If it isn't like that, people cooled or heated the ambience with mechanical elements. So a correct interaction between the buildings and natural resources is important to reach a thermal comfort. But achieving Thermal Comfort in all the buildings of a city as a unit will not achieve the whole city is thermally comfortable, because the complex interactions cause the problem needs to be solved as something systemic. This means that for a city or a set reach the Thermal Comfortability desired by its inhabitants, it should have been planned according to the urban variables that interact with the natural environment efficiently. Observing some old housing complexes in Elqui Valley, Chile, and the relationships between their natural and urban variables, some features lead to think that the environmental planning in these led to achieve a set with bioclimatic features. First, the evidences about the existence of an urban pattern in those old housing complexes, make thinking that the pattern would be a planned urban pattern, which generates interest in its study. In Chile, there have been few studies about Thermal Comfort, oriented to isolated buildings and indoor thermal comfort, but Bioclimatic Urban Patterns haven't been studied at all. In this sense, this investigation acquires a real importance and pretends to establish the relationship between urban variables and natural resources of the place that generates a good thermal comfort for its habitants. At the same time, the existence of a Bioclimatic Urban Pattern in Algarrobito, located in Elqui Valley basin, Chile, is analized. It is in this sense that the main purpose of this work is to determine the real existence of a Bioclimatic Urban Pattern, that links the urban and constructive form of the old villages of it with its microclimate. The methodology used is based on performing first the study of the microclimate of the place through the Bioclimatic Cards. To do this, weather stations, located in Elqui valley, near the place that was studied, were used to obtain information of climatological data. The different bioclimatic zones to the old town and potential areas of study in the set were identified, through an exhaustive review of the architectural information, a field reconnaissance work performed on the selected town and the application of the Local Climograph. This activity included a preliminary study of the local solar energy, the winds, the moisture, the temperatures, and their interaction with the set, allowing a first aproximation to troubles of outer space and housing. This allowed, based on the conditions of the place, vernacular architecture and materials, discovering an urban pattern in the old set, which allowed to give thermal comfort to its inhabitants and realize that the new set of the place did not follow this pattern, with the dysfunctions that it carried. These points demonstrated, in first place, the existence of a Bioclimatic Urban Pattern, the benefits of it, the importance of it as a cause of Thermal Comfortability, and therefore a better efficiency of energy, also that the new set doesn’t follow this Pattern at all, but that the posibility of rectification exists and, of course, that the new residencial development in Elqui Valley can be planned based on bioclimatic pattern discovered.

Sistemas radiolarios: geometrías y arquitecturas derivadas

Uno de los temas más importantes dentro del debate contemporáneo, es el que se refiere a la sostenibilidad a largo plazo de la sociedad tal y como la entendemos hoy. El ser humano está recuperando la sensibilidad perdida que le concebía como una pieza más dentro del ciclo natural de la vida. Por fin hemos entendido que no podemos ser auto suficientes e independientes del entorno natural que nos rodea. Más allá del respeto y del cuidado, está abierta la puerta del conocimiento infinito que nos brinda la naturaleza a todos los niveles y a todas las escalas. Dentro de la disciplina arquitectónica han existido ejemplos como Antoni Gaudí o Frei Otto que han referenciado su obra en el mundo Natural, encontrando en él las estrategias y bases para el diseño arquitectónico. Sin embargo han sido una minoría dentro del enorme elenco de arquitectos defensores del ángulo recto. En las últimas décadas, la tendencia está cambiando. No nos referimos tanto a la sensibilidad creciente por conseguir una mayor eficiencia energética que ha llevado a una puesta en valor de la arquitectura vernácula, trasladando su sabiduría a las estrategias bioclimáticas. Nos referimos a un caso específico dentro del amplio abanico de formas arquitectónicas que han aparecido gracias a la incorporación de las herramientas computacionales en el diseño y la producción. Las arquitecturas que nos interesan son las que aprovechan estas técnicas para analizar e interpretar las estrategias complejas y altamente eficientes que encontramos en la naturaleza, y trasladarlas a la disciplina arquitectónica. Esta tendencia que se enmarca dentro de la Biomímesis o Biomimética es conocida con el nombre de Bioarquitectura. La presente tesis trata de morfología y sobre todo de morfogénesis. El término morfología se refiere al estudio de una forma concreta que nos permite entender un caso específico, nuestro foco de atención se centra sin embargo en la morfogénesis, es decir, en el estudio de los procesos de generación de esas formas, para poder reproducir patrones y generar abanicos de casos adaptables y reconfigurables. El hecho de estudiar la forma no quiere decir que ésta sea una tesis “formalista” con la connotación peyorativa y gestual que se le suele atribuir a este término. La investigación concibe el concepto de forma como lo hace el mundo natural: forma como síntesis de eficiencia. No hay ninguna forma natural gratuita, que no cumpla una función determinada y que no se desarrolle con el mínimo material y gaste la mínima energía posible. Este afán por encontrar la “forma eficaz” es lo que nos hace traspasar la frontera de la arquitectura formalista. El camino de investigación morfológica se traza, como el título de la tesis indica, siguiendo el hilo conductor concreto de los radiolarios. Estos microorganismos unicelulares poseen unos esqueletos tan complejos que para poder entender su morfología es necesario establecer un amplio recorrido que abarca más de 4.000 años de conocimiento humano. Desde el descubrimiento de los sólidos platónicos, poliedros que configuran muchas de las formas globales de estos esqueletos; hasta la aplicación de los algoritmos generativos, que permiten entender y reproducir los patrones de comportamiento que existen detrás de los sistemas de compactación y teselación irregular de los esqueletos radiolarios. La tesis no pretende plantear el problema desde un punto de vista biológico, ni paleontológico, aunque inevitablemente en el primer capítulo se realiza un análisis referenciado del estado del conocimiento científico actual. Sí se analizan en mayor profundidad cuestiones morfológicas y se tratan los diferentes posicionamientos desde los cuales estos microorganismos han servido de referencia en la disciplina arquitectónica. Además encontramos necesario analizar otros patrones naturales que comparten estrategias generativas con los esqueletos radiolarios. Como ya hemos apuntado, en el segundo capítulo se aborda un recorrido desde las geometrías más básicas a las más complejas, que tienen relación con las estrategias de generación de las formas detectadas en los microorganismos. A su vez, el análisis de estas geometrías se intercala con ejemplos de aplicaciones dentro de la arquitectura, el diseño y el arte. Finalizando con un cronograma que sintetiza y relaciona las tres vías de investigación abordadas: natural, geométrica y arquitectónica. Tras los dos capítulos centrales, el capítulo final recapitula las estrategias analizadas y aplica el conocimiento adquirido en la tesis, mediante la realización de diferentes prototipos que abarcan desde el dibujo analítico tradicional, a la fabricación digital y el diseño paramétrico, pasando por modelos analógicos de escayola, barras metálicas, resina, silicona, látex, etc. ABSTRACT One of the most important issues in the contemporary debate, is the one concerning the long-term sustainability of society as we understand it today. The human being is recovering the lost sensitivity that conceived us as part of the natural cycle of life. We have finally understood that we cannot be self-sufficient and independent of the natural environment which surrounds us. Beyond respect and care, we’ll find that the gateway to the infinite knowledge that nature provides us at all levels and at all scales is open. Within the architectural discipline, there have been remarkable examples such as Antoni Gaudí or Frei Otto who have inspired their work in the natural world. Both, found in nature the strategies and basis of their architectural designs. However, they have been a minority within the huge cast of architects defenders of the right angle. In recent decades, the trend is changing. We are not referring to the growing sensitivity in trying to achieve energy efficiency that has led to an enhancement of vernacular architecture, transferring its wisdom to bioclimatic strategies. We refer to a specific case within the wide range of architectural forms that have appeared thanks to the integration of computer tools in both design and production processes. We are interested in architectures that exploit these techniques to analyse and interpret the complex and highly efficient strategies found in nature, and shift them to the discipline of architecture. This trend, which is being implemented in the framework of the Biomimicry or biomimetics, is called Bioarchitecture. This thesis deals with morphology and more specifically with morphogenesis. Morphology is the study of a concrete form that allows us to understand a specific case. However, our focus is centered in morphogenesis or, in other words, the study of the processes of generation of these forms, in order to replicate patterns and generate a range of adaptable and reconfigurable cases. The fact of studying shapes does not mean that this is a “formalistic” thesis with the pejorative connotation that is often attributed to this term. This study conceives the concept of shape as Nature does: as a synthesis of efficiency. There is no meaningless form in nature. Furthermore, forms and shapes in nature play a particular role and are developed with minimum energetic consumption. This quest to find the efficient shape is what makes us go beyond formalistic architecture. The road of morphological investigation is traced, as the title of the thesis suggests, following the thread of radiolaria. These single-cell microorganisms possess very complex skeletons, so to be able to understand their morphology we must establish a wide spectrum which spans throughout more than 4.000 years of human knowledge. From the discovery of the platonic solids, polyhedrons which configure a huge range of global shapes of these skeletons, through the application of generative algorithms which allow us to understand and recreate the behavioral patterns behind the systems of compression and irregular tessellation of the radiolarian skeletons. The thesis does not pretend to lay out the problem from a biological, paleontological standpoint, although inevitably the first chapter is developed through an analysis in reference to the current state of the science. A deeper analysis of morphological aspects and different positionings is taken into account where these microorganisms have served as reference in the architectonic discipline. In addition we find necessary to analyse other natural patterns which share generative strategies with radiolarian skeletons. Aforementioned, in the second chapter an itinerary of the most basic geometries to the more complex ones is addressed. These are related, in this chapter, to the generative strategies of the shapes found in microorganisms. At the same time, the analysis of these geometries is placed among examples of applications inside the fields of architecture, design and the arts. To come to an end, a time chart synthesizes and relates the three investigation paths addressed: natural, geometrical and architectonic. After the two central chapters, the final chapter summarises the strategies analysed and applies the knowledge acquired throughout the thesis. This final chapter is shaped by the realization of different prototypes which range from traditional analytical drawings, to digital fabrication and parametric design, going through plaster analogical models, metal bars, resin, silicone, latex, etc.

O patrimônio invisível: arquitetura popular urbana de municípios do período colonial brasileiro

No Brasil, ações institucionais de preservação de bens imóveis tem foco principal na arquitetura erudita, colocando em segundo plano de importância a arquitetura produzida por indivíduos com formação escassa e empírica. Este trabalho contribui para o reconhecimento da arquitetura popular (vernácula) como patrimônio cultural. Trabalha-se na criação de acervo fotográfico de edificações e equipamentos urbanos produzidos durante o período colonial, nos municípios de Tiradentes, Mariana, Ouro Preto e Diamantina (Minas Gerais). São realizadas visitas in loco para reconhecimento e seleção de objetos a serem fotografados. O registro fotográfico é realizado com câmera digital reflex de objetiva simples, privilegiando-se objetos cuja deterioração permite a observação de materiais e técnicas construtivas. Como resultado parcial da pesquisa, foram produzidas 4.522 imagens, documentando o abandono de edificações residenciais e chafarizes setecentistas e oitocentistas, bem como a descaracterização de exemplares de edificações coloniais populares habitadas, cujas paredes de adobe e pau-a-pique são substituídas por alvenaria de tijolos pelos moradores. Tornam-se necessárias ações para o reconhecimento – no âmbito do Poder Público e das comunidades locais – da relevância histórica da arquitetura popular, entendida como produto articulado e coerente de contribuições das culturas distintas que formaram essa região do Brasil.

Sustaining culture through architecture : how can local, vernacular architectural principles be adapted to contemporary design in a village in Guyana

This thesis explores how architecture can adapt local vernacular design principles to contemporary building design in a rural setting. Vernacular buildings in Guyana present a unique and coherent set of design principles developed in response to climatic and cultural conditions. The concept of “habitus” proposed by philosopher Pierre Bourdieu describing the evolving nature of social culture was used to interpret Guyanese local buildings. These principles were then applied to the design of a Women’s Center in the village of Port Mourant on the east coast of Guyana. The design specifically interpreted the “bottom-house” of local Guyanese architecture, an inherently flexible transitional outdoor space beneath raised buildings. The design of the Women’s Center demonstrates how contemporary architectural design can respond to climatic requirements, local preferences and societal needs to support the local culture.

Place and displacement : southeast Queensland architecture

The "vernacular" housing tradition of southeast Queensland is easily identifiable. Its history is more complex. This study seeks to challenge two popular conceptions of the "Queenslander" history by showing that they actually provide contradictory explanations. The aim is to produce a more complex account of local architecture and its historical explanation so that both its past and its present practices can be better understood as a distinctly subtropical idiom. This discussion shows that such practices may respond to common concerns but that are also ever-changing.

The Casual Buttress:Certainty and Contingency in the Study of the Vernacular

Impromptu accretions such as the buttresses in Robin Walkers photograph are moments that are familiar in the architecture of the everyday. Indeed the buttress is a very common occurrence with these cottages in particular, their mud walls being poor at resisting concentrated lateral loading. While not always required the buttress emerges when requirements to create spaces to support inhabitation are at odds with the external form and construction of the buildings. These points of disjunction are resolved in an additive fashion externally. The location varies from structure to structure, occasionally the buttress is be used as a point of connection for further structures, becoming subsumed in outbuildings or walls. This preponderance to variety means that it is omitted from the reductive drawings of type that classify these buildings and yet it occurs in enough for it to have a fundamental and transformative relationship to the generality of cottages.
What is of interest is not so much what these structures hold in common, but rather what differentiates them. It is their capacity for variety within a defined range which allows them at once to speak at once of broader social structures and of a specific place and person.
Using the above observation this paper treats of the failure of architectural typological studies of the vernacular to derive anything other than formal exemplars, and posits an alternative approach based on a focus on the technical construction of such buildings.

Architecture and other Architectures: Mapping the Production of Insular Space in the Pearl River Delta (China) and Jakarta (Indonesia)

Globalization is widely regarded as the rise of the borderless world. However in practice, true globalization points rather to a “spatial logic” by which globalization is manifested locally in the shape of insular space. Globalization in this sense is not merely about the creation of physical fragmentation of space but also the creation of social disintegration. This study tries to proof that global processes also create various forms of insular space leading also to specific social implications. In order to examine the problem this study looks at two cases: China’s Pearl River Delta (PRD) and Jakarta in Indonesia. The PRD case reveals three forms of insular space namely the modular, concealed and the hierarchical. The modular points to the form of enclosed factories where workers are vulnerable for human-right violations due to the absent of public control. The concealed refers to the production of insular space by subtle discrimination against certain social groups in urban space. And the hierarchical points to a production of insular space that is formed by an imbalanced population flow. The Jakarta case attempts to show more types of insularity in relation to the complexity of a mega-city which is shaped by a culture of exclusion. Those are dormant and hollow insularity. The dormant refers to the genesis of insular– radical – community from a culture of resistance. The last type, the hollow, points to the process of making a “pseudo community” where sense of community is not really developed as well as weak social relationship with its surrounding. Although global process creates various expressions of territorial insularization, however, this study finds that the “line of flight” is always present, where the border of insularity is crossed. The PRD’s produces vernacular modernization done by peasants which is less likely to be controlled by the politics of insularization. In Jakarta, the culture of insularization causes urban informalities that have no space, neither spatially nor socially; hence their state of ephemerality continues as a tactic of place-making. This study argues that these crossings possess the potential for reconciling venue to defuse the power of insularity.

Sveta Bogorodica (The Church of the Holy Mother), Zavoj, Macedonia : writing about an insignificant vernacular building

Sveta Bogorodica (Church of the Holy Mother), Zavoj, is a small church built in 1934 in a village in the Republic of Macedonia. It presented a quintessential architectural division between a richly ornamented interior and a pure white formal exterior. The paper will examine the question of tradition in relation to architecture. What of the formal Byzantine architectural tradition is inherited in this folk vernacular church building? Secondly, tradition as an inherited liturgical ritual and ceremony. How are these two forms of tradition autonomous or intertwined, and how the question about transcendence in architecture pursued in the 2005 paper on Hagia Sofia might be understood within the parameters offered by this church building, will be explored in the paper .

Diversity and architecture

Architecture can be defined as the art and tectonics of place making. The discipline of architecture involves a broad set of practices including design of the built environment, development of architectural projects either community~ based or oriented towards a (private) client, and advisory work for governments. Architecture also involves a wide spectrum of knowledge including urban design and urban planning, and a variety of architectural ideas, theories and movements. Various dominant ideologies have manifested themselves in built form, whereas other, marginal cultural parameters have emerged in the vernacular or traditional architecture. Architecture is considered the medium through which society is organised and materialised. It resonates with symbolic meaning as well as pragmatic order through built places.

Geographical cataloguing of earthen architecture in Soria, Spain

This paper discusses the most relevant earth construction techniques that have been employed in the province of Soria (Spain). The objectives of the research are, first, to locate and catalogue each building techniques with earth within the geographic regions and environmental units and their relation to physical and human environment. Then, the second aim is analyze these techniques and characterize them in terms of material, components and construction processes. Three types are studied: the construction of rammed-earth walls, adobe masonry and timber frame filled with adobe.
