Criterios de restauración, intervención y revitalización del patrimonio industrial : la fábrica de gas de San Paolo en Roma

La tesis está centrada en el patrimonio industrial, y trata de ahondar en los temas enunciados en el título, Criterios de restauración, intervención y revitalización del patrimonio industrial (capítulo 1). La fábrica de gas de San Paolo en Roma (capítulo 2): En el primer capítulo, se profundiza en los criterios institucionalizados de actuación en el patrimonio, pero también se habla sobre la singularidad, los valores originales, estratificados en cada construcción y su contexto. Ello resume la intención de la doctoranda al entender la necesidad del análisis de cada obra en modo profundo, concreto y abierto a novedosos acercamientos, antes de su transformación. Al hablar de intervención frente a restauración, se aborda la conocida polémica que plantea el modo de acercarse al legado histórico. Parece necesario enunciar cómo se consideran en el trabajo estos términos. Mientras la restauración (como diría Cesare Brandi, constituye el momento metodológico del reconocimiento de la obra de arte en su consistencia física y en su doble polaridad estética e histórica, en orden a su transmisión al futuro) es una acción más restrictiva, que implica atención suma a la recuperación y conservación de los valores significativos y únicos del bien, en comunicación con un (posible) equipo interdisciplinar; por intervención se entiende aquí un desarrollo más personal y libre por parte del proyectista, en el que se produce un proceso dialéctico entre la preexistencia y el posicionamiento crítico adoptado a la hora de dar un obligado nuevo uso a ese bien. Es decir, el contraste está en el diferente reconocimiento de la materialidad física y sus significados. En torno a la restauración/intervención, se analizan las perspectivas de actuación en España e Italia, contrastando factores como la formación del arquitecto o el entorno laboral-cultural, y utilizando el método analítico comparativo de casos. Habría un tercer concepto: el de revitalización del patrimonio industrial, Éste hace referencia a su transformación, a sus usos más comunes y compatibles, a la redimensión artística que ha experimentado la arquitectura industrial gracias al arte contemporáneo y a su relación con la Modernidad. Por último, se enuncia en el título el caso de estudio, la Fábrica, que ocupa el segundo capítulo. Se trata de un enorme conjunto industrial singular semi abandonado en el confín del centro histórico, cuyo protagonista es un gran gasómetro, que la autora ha tenido la oportunidad de descubrir en su estancia en la Ciudad Eterna. Este barrio constituyó el primer y único sector industrial de la Roma moderna a inicios del siglo XX. Por varias causas históricas y voluntad política, la ciudad prácticamente no tuvo más desarrollo industrial que el área mencionada, donde se implantaron servicios y actividades de gran transformación (Matadero, Mercados Generales, Almacenes Fluviales, Central Montemartini o esta fábrica). A partir de 1920, se empezó a construir un tejido productivo que la llevó de la situación de posguerra al milagro económico. Frente al mito de la Roma monumental o de la Roma cotidiana, aparece el aspecto industrial como mito de la contemporaneidad. Sin embargo, esta ciudad es demasiado antigua como para convertirse en moderna, y su proceso industrial en contraste con su larga historia resulta breve. La inmediata relación de la fase industrial romana con el resultado de este desarrollo viene identificada con las instalaciones señaladas, más significativas por su excepcionalidad que por la duración del momento irrepetible que representan. Su presencia física perdura a pesar de su abandono, aisladas tras su muro perimetral y casi desconocidas. Esto las hace apetecibles para la especulación inmobiliaria y resultan un caso de estudio ideal para realizar un Plan de Intervención Global, en el que determinar una serie de intervenciones necesarias, usos compatibles y directrices para la ordenación del conjunto, coherentes con los conceptos manejados en el primer capítulo. ABSTRACT The thesis focuses on industrial heritage, delving into the topics listed in its title, Criteria for the restoration, intervention and revitalisation of industrial heritage (chapter 1). The San Paolo gas factory in Rome (chapter 2): Chapter one elaborates on the official criteria to take action on heritage, but also deals with the singularity and original values unique to each construction and its context. This underlines the PhD candidate’s intentions by understanding the need for an in-depth and specific analysis, open to novel approaches to each site before its transformation. When speaking of intervention, as opposed to restoration, we address the well-known controversy that stems from the different ways of approaching historical heritage. It seems necessary to explain how these terms are interpreted in this piece of work. Whereas restoration (as Cesare Brandi would say, constitutes the methodological moment in which the work of art is appreciated in its material form and in its historical and aesthetic duality, with a view to transmitting it to the future) is a more restrictive action, demanding the utmost attention to the recovery and preservation of the piece of heritage’s defining and exceptional values, (ideally) in communication with a interdisciplinary team. By intervention, we hereby understand a more personal and free procedure carried out by the designer in which a dialectical process takes place between preexistence and the critical stance taken in order to give that good a much needed new use. That is, contrast lies in the different recognition of physical materiality and its meanings. As for the restoration/intervention dilemma, the different courses of action followed in Spain and Italy will be analysed, contrasting the architects’ training, the labourcultural environment and taking an analytical comparative case study method. There is a third concept: the revitalisation of industrial heritage, which refers to its transformation, its most common and compatible uses, the artistic redimensioning that industrial architecture has experienced thanks to contemporary art, and its relationship with Modernity. Lastly, the title refers to the case study, i.e., the analysis of the Factory, which makes up chapter 2. It is an enormous and semiabandoned peerless industrial complex on the edge of the historical city centre whose main landmark is a huge gasometer, which the author had the chance to discover during her stay in the Eternal City. This district made up the first and only industrial sector in the modern Rome of the early 20th century. Due to a number of reasons, both historical and political, barely no further industrial development took place in the city beyond the mentioned area, where processing services and activities were set up (Slaughterhouse, General Markets, Riverside Warehouses, Montemartini Power Plant or the said factory). In the 1920s began the construction of the productive fabric that raised the city from its postwar plight to the economic miracle. As opposed to the myth of monumental Rome and daily-life Rome, this industrial Rome rose as contemporaneity’s myth. However, this city is too ancient to become modern, and its industrial process strikes us as brief when confronted with its long history. The close relationship between Rome’s industrial stage and the consequences of this development is best represented by the aforementioned facilities, more relevant due to their uniqueness than the length of the once-in-a-lifetime moment they represent. Their physical presence lives on despite abandonment and isolation, as they stand vastly unknown behind their perimeter walls. This renders them appealing to property speculators, becoming an ideal case study for the creation of a Global Intervention Plan in which to determine a series of necessary actions, compatible uses and directives, all of them consistent with the concepts dealt with in chapter 1. RIASSUNTO La tesi è focalizzata sul patrimonio industriale e cerca di approfondire le tematiche contenute nel titolo, Criteri di restauro, intervento e rivitalizzazione del patrimonio industriale (capitolo 1). La Fabbrica del gas di San Paolo a Roma (capitolo 2): Nel primo capitolo vengono presi in esame i criteri istituzionalizzati di attuazione nel patrimonio, ma si parla anche della unicità, i valori originali, stratificati in ogni costruzione ed il suo contesto. Questo riassume l’intenzione della dottoranda di capire la necessità dell’analisi di ogni opera in modo profondo, concreto e aperto a nuovi approcci, prima della sua trasformazione. Nel parlare di intervento versus restauro, si affronta la famosa polemica che considera il modo di avicinarsi all’eredità storica. Appare necessario precisare come questi termini sono considerati in questo lavoro. Mentre il restauro (come direbbe Cesare Brandi, costituisce il momento metodologico del riconoscimento dell’opera d’arte nella sua consistenza fisica e nella duplice polarità estetica e storica, in vista della sua trasmissione nel futuro) è un’azione più restrittiva, e quindi implica massima attenzione al recupero e conservazione dei valori significativi ed unici del bene, in comunicazione con una (eventuale) squadra interdisciplinare; per intervento si intende qui un processo più personale e libero del progettista, nel quale si produce uno sviluppo dialettico tra la preesistenza e la posizione critica adottata quando si deve dare un nuovo uso di quel bene. Vale a dire che il contrasto risiede nel diverso riconoscimento della materialità fisica e i loro significati. Intorno al restauro / intervento, si analizzano le prospettive di attuazione in Spagna e Italia, contrastando diversi fattori come la formazione dell’architetto o l’ambiente lavorativo-culturale, ed impiegando il metodo analitico comparativo dei casi. Ci sarebbe un terzo concetto: quello della rivitalizzazione del patrimonio industriale. Questo fa riferimento alla sua trasformazione, ai suoi usi più comuni e compatibili, al ridimensionamento artistico vissuto dall’archeologia industriale grazie all’arte contemporanea ed al suo rapporto con la Modernità. In ultimo, si enuncia nel titolo il caso di studio, ovvero l’analisi della Fabbrica, che occupa il secondo capitolo. Si tratta di un enorme complesso industriale semi-abbandonato al confine con il centro storico, il cui protagonista è un grande gasometro, che l’autrice ha avuto modo di scoprire durante il suo soggiorno nella Città Eterna. Questo quartiere costituì il primo e unico moderno settore industriale della Roma moderna all’inizio del Novecento. Per diverse ragioni storiche e volontà politiche, la città praticamente non ha subito ulteriore sviluppo industriale oltre l’area citata, dove si impiantarono servizi e attività di grande trasformazione (Mattatoio, Mercati Generali, Magazzini Generali, Centrale Montemartini o questa fabbrica). Dal 1920, si inizió a costruire un tessuto prodottivo che portò la città dalla situazione post-bellica al miracolo economico. Di fronte al mito della Roma monumentale o della Roma quotidiana, appare questa Roma industriale come mito della contemporaneità. Tuttavia, questa città è troppo antica per diventare moderna, ed il suo processo industriale in contrasto con la sua lunga storia risulta breve. Il rapporto diretto della fase industriale romana con il risultato di questo sviluppo viene identificato con gli impianti segnalati, più significativi per la loro unicità che per la durata del momento irripetibile che rappresentano. La loro presenza fisica perdura nonostante l’abbandono, isolati dietro il loro muro di cinta e quasi sconosciuti. Questo li rende auspicabile per la speculazione immobiliare e sono un caso ideale per eseguire un Piano di Intervento Globale, che determini una serie di interventi necessari, usi compatibili e linee guida per la pianificazione del tutto, in linea con i concetti utilizzati nel primo capitolo.

Espacios máximos con recursos mínimos : edificio Central Lechera CLESA, Alejandro de la Sota

La tesis aborda el estudio de la Central lechera CLESA, uno de los edificios industriales de Alejandro de la Sota más significativos de la década de los años cincuenta en España. Las centrales lecheras fueron abordadas por Sota en distintas ocasiones entre 1955 y 1969, siendo CLESA la única de todas ellas que llega a construirse. Se trata de uno de los exponentes más brillantes de la arquitectura moderna industrial española de la posguerra, incluido en "La arquitectura de la industria, REGISTRO DOCOMOMO IBÉRICO”1 entre la veintena de edificios seleccionados de la arquitectura madrileña de este periodo. Plantea una solución singular para alcanzar la diafanidad exigida en la implantación del proceso de producción. La estructura de las naves se realiza con hormigón pretensado, siendo uno de los pioneros en la utilización de esta técnica. La hipótesis de partida considera la realidad del proyecto construido como respuesta desde la arquitectura a un programa industrial resuelto con sencillez, que partiendo de una economía de recursos que le es inherente, consigue desde la coherencia del planteamiento, soluciones donde la complejidad espacial constituye una respuesta eficaz y del máximo interés. Los objetivos de esta tesis son contribuir a un conocimiento riguroso del edificio, que permita descubrir la particularidad de su entramado espacial y el interés de las soluciones adoptadas en su configuración final, en aras de contrastar su calidad arquitectónica. El edificio de la Central Lechera CLESA, si bien es un edificio muy conocido, lo es de una manera superficial. Aparece en numerosas publicaciones, en muchas ocasiones formando parte de un relato extenso de la obra de su autor. El libro monográfico publicado en 2007 por la Fundación Alejandro de la Sota, cuya edición está a cargo de Teresa Couceiro, es la única publicación específica sobre él. Tras una breve introducción, en la que se destaca la intensa dedicación de Sota a esta obra, reúne una colección de planos, fotografías y croquis, junto a la memoria del proyecto. Ofrece una visión fragmentada, que permite vislumbrar el interés de esta obra, pero no facilita comprenderla en su integridad. Es importante destacar la publicación de CLESA en el libro editado por Pronaos (1989), que incluye una selección, realizada por el autor, de plantas, alzados y secciones que corresponden al proyecto construido junto a fotografías de la obra terminada, además de un breve texto tan conciso como esclarecedor. Sobre Alejandro de la Sota se han escrito, tesis doctorales, numerosos artículos, varios libros así como realizado exposiciones que recogen su obra global, reflejados en este documento en las consiguientes bibliografías específicas. Cabe destacar la exposición realizada en la sede del COAM en 2014, con ocasión de su centenario, que el edificio CLESA protagoniza en cierto modo, por su riesgo de desaparición.2 La tesis se estructura en cuatro capítulos: descripción, análisis, síntesis y conclusiones. El primer capítulo contempla la descripción del edificio objeto de la tesis, con una introducción que nos sitúa en el contexto histórico, económico, cultural y social en el que se desarrolla el encargo, proyecto y obra de la central lechera. La descripción propiamente dicha del conjunto industrial, partiendo del encargo de la central lechera al autor del proyecto, pasando por el anteproyecto, el proyecto visado y llegando a la obra realizada. Se compara el proyecto visado, la obra terminada y la CLESA publicada, así como el devenir del edificio. La segunda parte corresponde al análisis, en primer lugar desde el programa como planteamiento general, estudiando las circulaciones, relaciones espaciales, geométricas, esqueléticas, geográficas -parte a parte- que integran el conjunto de la central. La estructura, introducción explicativa de las soluciones adoptadas por Alejandro de la Sota; análisis del sistema esquelético del edificio por partes, operaciones geométricas y espaciales. Construcción, análisis de la materialización de la obra, sistemas constructivos empleados en cerramientos, cubiertas, lucernarios; de lo general a lo particular, estudiando los sistemas. Finalmente a través de la pequeña escala se compendian elementos singulares que forman parte de sistemas complejos, como las múltiples escaleras, barandillas, carpinterías, miradores. Se recapitula en una síntesis que configura un todo con la suma de las partes, mediante la utilización de recursos de enlace de esa arquitectura aditiva, como es el módulo, los recorridos y los enlaces visuales. El capítulo final de Conclusiones contrasta la hipótesis de partida de la tesis en cuanto a una arquitectura de espacios máximos con recursos mínimos. Recoge también diversas reflexiones como la dialéctica entre el espacio fragmentado y el espacio único; crecimiento expansivo o inclusivo; imagen singular y representación; escala doméstica y escala industrial; renuncias estructurales o limitaciones de medios. Quizás, el mayor interés de esta tesis reside los dibujos realizados en axonométrica del complejo CLESA, que han permitido restituir y reconstruir idealmente la fábrica al inicio de su actividad. Teniendo en cuenta su posible desaparición total o parcial, esta restitución cobra relevancia como testimonio de lo que fue. ABSTRACT The thesis deals with the study of CLESA's Dairy Plant, one of the most significant industrial buildings of the Decade of the fifties in Spain, by Alejandro de la Sota. The Dairies were addressed by Sota at various occasions between 1955 and 1969, being the CLESA plant the only one that is has been built. This is one of the most brilliant exponents of Spanish industrial post-war modern architecture, included in "The architecture industry, IBERIAN DOCOMOMO RECORD"3 between the score of selected buildings of Madrid architecture of this period. It poses a singular solution to achieve the openness of the space required in the implementation of the manufacturing process. The structure of the nave is done with prestressed concrete, being one of the pioneers in the use of this technique. The initial hypothesis considers the reality of the project built from the architecture in response to an industrial program solved with simplicity, that from a resource economy that is inherent, gets from the consistency of the approach, solutions where the space complexity is an effective response of great interest. The objectives of this thesis are to contribute to a rigorous knowledge of the building, which allows to discover the particularity of its space lattice and the interest of the solutions adopted in its final configuration, in order to contrast its architectural quality. The building of the Central Lechera CLESA, despite it is a well known building, is in a superficial way. It appears in several publications, often as part of an extensive account of the work of its author. The monograph published in 2007 by the Foundation Alejandro de la Sota, whose edition is run by Teresa Couceiro, is the only specific publication about it. After a brief introduction, in which Sota's intense dedication to this work stands out, it brings together a collection of drawings, photographs and sketches, along with the project report. It offers a fragmented view, which enable to glimpse the interest of this work, but not helps to understand it in full. It is important to highlight the publication of CLESA in the book edited by Pronaos (1989), which includes a selection made by the author of plants, elevations and sections corresponding to the project built, next to photographs of the finished construction, in addition to a brief text as concise as enlightening. About Alejandro de la Sota have been written doctoral thesis, numerous articles, several books as well as held exhibitions collecting his global work, which have been reflected in this document in the resulting specific bibliographies. It should be noted the exhibition in COAM headquarters in 2014, on the occasion of its Centennial, where the building CLESA has a leading role, in a certain way, because of its risk of disappearance.4 The thesis is structured in four chapters: description, analysis, synthesis, and conclusions. The first chapter provides the description of the building object of this thesis. Includes an introduction that puts us in the historic, economic, cultural and social context in which it is developed the commission, the project and construction of the dairy building. The description itself of the industrial complex, starts with the order of the dairy to the author of the project, moves through the draft, the visa project and reaches the completion of the work. The visa project, CLESA's finished and published work, as well as the future of the building is compared. The second part corresponds to the analysis, first from the program as a general approach, studying the circulations, geometric, spatial, skeletal, geographical relations - bit by bit - comprising the manufacturing plant ("la central"). The structure, explanatory introduction of the solutions adopted by Alejandro de la Sota; analysis of the skeletal system of the building by parts, geometric and spatial operations. Construction, analysis of the realization of the work, constructive systems used in the building enclosures, roofs, skylights; from the general to the particular and studying the systems. Finally through small scale unique elements that are part of complex systems, such as multiple stairs, railings, carpentry, viewpoints are summarized. It is recapitulated in a synthesis which forms a whole with the sum of the parts, using linking resources that belongs to the additive architecture, such as the module, tours and visual links The final chapter of Conclusions contrast the hypothesis of the thesis regarding the maximum space architecture with minimal resources. It also includes various reflections as the dialectic between the fragmented space and the single space; expansive or inclusive growth; unique image and representation; domestic and industrial scale; structural abandonment or limitation of means. Perhaps the greatest interest of this thesis lies in the axonometric drawings made of the CLESA complex, which ideally have allowed to restore and rebuild the factory back to the beginning of its activity. Considering its potential full or partial disappearance, such recovery becomes relevant as a testimonial evidence of what it was.

Renewable energy infrastructure. A challenge for Venezuelan industrial construction

The relevance of renewable energy has grown significantly in our global society. Important efforts are oriented to sustain it. Renewable energy depends on different technical, financial environmental and social complex processes. From the point of view of industrial construction sector this research evaluates some of the current trends in energy generation and use in Venezuela as well as environmental consequences and risks that derive from these. Additionally, authors highlight the importance of infrastructure as key issue to sustain renewable energy generation and use. The study present references of some energy renewable projects in process in Venezuela and the main problems that constrain their performance. Conclusions evidence the complex nature of industrial construction and suggest the need to improve industrial construction competitivenes as a strategy oriented to enhance renewable energy offer in the country. Additionally it is proposed to all stakeholders to work toghether to correct the conditions that currently limit industrial construction development. This is part of ongoing research.

Improved heuristic drift elimination with magnetically-aided dominant directions (MiHDE) for pedestrian navigation in complex buildings

The main problem of pedestrian dead-reckoning (PDR) using only a body-attached inertial measurement unit is the accumulation of heading errors. The heading provided by magnetometers in indoor buildings is in general not reliable and therefore it is commonly not used. Recently, a new method was proposed called heuristic drift elimination (HDE) that minimises the heading error when navigating in buildings. It assumes that the majority of buildings have their corridors parallel to each other, or they intersect at right angles, and consequently most of the time the person walks along a straight path with a heading constrained to one of the four possible directions. In this article we study the performance of HDE-based methods in complex buildings, i.e. with pathways also oriented at 45°, long curved corridors, and wide areas where non-oriented motion is possible. We explain how the performance of the original HDE method can be deteriorated in complex buildings, and also, how severe errors can appear in the case of false matches with the building's dominant directions. Although magnetic compassing indoors has a chaotic behaviour, in this article we analyse large data-sets in order to study the potential use that magnetic compassing has to estimate the absolute yaw angle of a walking person. Apart from these analysis, this article also proposes an improved HDE method called Magnetically-aided Improved Heuristic Drift Elimination (MiHDE), that is implemented over a PDR framework that uses foot-mounted inertial navigation with an extended Kalman filter (EKF). The EKF is fed with the MiHDE-estimated orientation error, gyro bias corrections, as well as the confidence over that corrections. We experimentally evaluated the performance of the proposed MiHDE-based PDR method, comparing it with the original HDE implementation. Results show that both methods perform very well in ideal orthogonal narrow-corridor buildings, and MiHDE outperforms HDE for non-ideal trajectories (e.g. curved paths) and also makes it robust against potential false dominant direction matchings.

Evaluating alternative industrial network organizations and information systems

Purpose – The purpose of this paper is to present a simulation‐based evaluation method for the comparison of different organizational forms and software support levels in the field of supply chain management (SCM). Design/methodology/approach – Apart from widely known logistic performance indicators, the discrete event simulation model considers explicitly coordination cost as stemming from iterative administration procedures. Findings - The method is applied to an exemplary supply chain configuration considering various parameter settings. Curiously, additional coordination cost does not always result in improved logistic performance. Influence factor variations lead to different organizational recommendations. The results confirm the high importance of (up to now) disregarded dimensions when evaluating SCM concepts and IT tools. Research limitations/implications – The model is based on simplified product and network structures. Future research shall include more complex, real world configurations. Practical implications – The developed method is designed for the identification of improvement potential when SCM software is employed. Coordination schemes based only on ERP systems are valid alternatives in industrial practice because significant investment IT can be avoided. Therefore, the evaluation of these coordination procedures, in particular the cost due to iterations, is of high managerial interest and the method provides a comprehensive tool for strategic IT decision making. Originality/value – Reviewed literature is mostly focused on the benefits of SCM software implementations. However, ERP system based supply chain coordination is still widespread industrial practice but associated coordination cost has not been addressed by researchers.

Emotions and the Engineering of Adaptiveness in Complex Systems

A major challenge in the engineering of complex and critical systems is the management of change, both in the system and in its operational environment. Due to the growing of complexity in systems, new approaches on autonomy must be able to detect critical changes and avoid their progress towards undesirable states. We are searching for methods to build systems that can tune the adaptability protocols. New mechanisms that use system-wellness requirements to reduce the influence of the outer domain and transfer the control of uncertainly to the inner one. Under the view of cognitive systems, biological emotions suggests a strategy to configure value-based systems to use semantic self-representations of the state. A method inspired by emotion theories to causally connect to the inner domain of the system and its objectives of wellness, focusing on dynamically adapting the system to avoid the progress of critical states. This method shall endow the system with a transversal mechanism to monitor its inner processes, detecting critical states and managing its adaptivity in order to maintain the wellness goals. The paper describes the current vision produced by this work-in-progress.

Arquitectura industrial tabacalera en la España peninsular: secaderos y fábricas

La Arquitectura industrial del tabaco en España está representada por dos tipos de construcciones, que corresponden a las dos fases en las que se divide el proceso de producción del tabaco: los secaderos (arquitectura bioclimática donde se realiza el secado), y las fábricas (centros donde se elabora el tabaco procedente de los secaderos). Las fábricas se repartieron por todo el territorio español, ocupando preferiblemente los lugares costeros, aunque existen casos en los que su localización obedecía a razones políticas. Estos edificios, en su mayoría, incluidos en los centros históricos de las ciudades, han cambiando de uso, y las antiguas fábricas de tabaco se han transformado en su mayoría, en centros de cultura, o centros sociales y representativos. La tesis surge del análisis de las características constructivas de la arquitectura industrial del tabaco: de los secaderos y de las fábricas, por tratarse de una tipología con suficiente entidad y un ejemplo de arquitectura bioclimática de producción en el caso de los secaderos, y por conseguir haberse adaptado a otros usos en el caso de las fábricas. La arquitectura de producción emplea un lenguaje acorde con los avances de la industrialización, anticipando materiales y estructuras, y condensando en una tipología específica las complejas relaciones establecidas entre producto, hombres y espacio. Estos edificios tuvieron una extensa implantación en el territorio, y se caracterizan por una serie de valores tecnológicos, arquitectónicos, sociológicos y paisajísticos, que hacen de ellos un documento de primera magnitud para conocer: la evolución e implantación de las técnicas constructivas (materiales y estructuras), los procesos de innovación tipológica y la estructura económica y procedimientos técnicos utilizados. El territorio en el que se insertan constituye su contexto territorial, por lo que no sería adecuado considerar estos edificios como elementos aislados, sin analizar la relación con el entorno en el que se generaron. Por este motivo, se analizan las condiciones higrotérmicas ambientales de los secaderos para compararlas con las de confort humano y establecer relaciones y parámetros compatibles. Los ejemplos analizados de secaderos son todos de fábrica. El uso del ladrillo como módulo principal para la elaboración de un edificio, supone la consideración de un “grado cero” de todo el aparato constructivo y compositivo de la arquitectura. Dejar el ladrillo visto, supone hacer explícitos todos los procesos acumulativos. Este elemento mínimo, permite unas posibilidades enormemente abiertas, pero no absolutamente aleatorias, que definen su propia lógica combinatoria. La exigencia de sinceridad, característica de la arquitectura industrial, en la exposición de los materiales, exhibiéndolos en su propia naturaleza y en el modo real de ser utilizados, se hace patente en este tipo de construcción. Se realiza un estudio de permeabilidad en las fachadas de los secaderos, para determinar el grado de ventilación y su relación con la orientación, el patrón de celosía empleado y el volumen total. Este sistema de acondicionamiento climático específico, puede servir de recurso a otras construcciones, por lo que se podría trasladar el sistema constructivo y formal de los secaderos a otros usos, desde una doble vertiente: Arquitectura para la adaptación climática al entorno. Arquitectura como generadora de condiciones climáticas específicas, en el interior. La utilidad de los secaderos es fundamentalmente: proporcionar sombra, ventilación y un espacio cubierto, pero permeable en sus fachadas. La arquitectura industrial debe ser reconocida dentro del conjunto patrimonial, debido a sus características propias que permiten su diferenciación del resto de la arquitectura. Conocer la estructura productiva permite analizar correctamente estas construcciones, ya que el programa inicial es básico para entender la organización del espacio interior. Las fábricas no se situaron cerca de las zonas de producción del tabaco, excepto en dos casos: Cádiz y Palazuelo, en los que existen secaderos y campos de cultivo de hoja de tabaco en las áreas cercanas. La principal causa de esta separación es que el proceso de obtención de tabaco es un proceso dividido en dos fases principales: proceso primario y proceso secundario. En el proceso primario la hoja de tabaco se seca en los secaderos, en los que es determinante el clima, pero únicamente en el caso del secado del tabaco al aire. En el proceso secundario sin embargo, el tabaco llega previamente tratado a las fábricas, por lo que no influye el clima en esta parte del proceso. Esta razón determina que en las áreas climáticas donde se centra el estudio, haya zonas en las que existen fábrica y secaderos y otras en las que únicamente existe fábrica, o sólo secaderos. La localización de las fábricas atendía a razones de muy diferente índole, las más importantes fueron: geográficas, estratégicas, y políticas. En la mayoría de las fábricas la elección de la ciudad de emplazamiento estaba ligada a la recepción de la materia prima, que principalmente se hacía por vía marítima, o acuática (el caso de Sevilla), y por vía terrestre, utilizando como medio de transporte el ferrocarril. Sólo dos casos, de las antiguas fábricas, corresponden a razones políticas, son las dos únicas que no están en la costa: Madrid y Logroño. La de Madrid se construyó por centralidad política, y porque geográficamente ocupaba el punto central de todas las comunicaciones terrestres por carretera y ferrocarril. Muchas de las fábricas se situaron cercanas a las estaciones de ferrocarril. La de Logroño atendió, sin embargo, a razones políticas. Para finalizar, se realiza un estudio comparativo de las fábricas de Sevilla, Madrid y San Sebastián. Las razones que justifican esta elección son: - La de Sevilla fue históricamente la primera fábrica y la más importante. - La de Madrid fue la más importante a nivel administrativo, la sede de Tabacalera se instaló en la capital, y después de la de Sevilla, fue la que sirvió de modelo al resto de las fábricas. - La de San Sebastián era la más grande del Norte. Los análisis que se han realizado son de: volumen y superficies de patios, superficies de cubierta, permeabilidad o huecos en fachadas, orientación y soleamiento de patios, distribución espacial interior y organización, y evolución de usos. Podemos observar que en la mayoría de estas fábricas ha habido una transformación en el uso, pasando de ser edificios industriales a edificios culturales. Estas construcciones se pueden considerar como infraestructuras adaptables, por ser útiles, sostenibles y funcionales. ABSTRACT The Spanish industrial architecture of tobacco is represented by two construction types that correspond to the two phases of tobacco production: the drying sheds (bioclimatic constructions where the drying process takes place) and factories (centres where tobacco is processed after the drying process). The factories were distributed throughout the Spanish territory, preferably occupying coastal locations, although some of them were located elsewhere following political reasons. Most of the buildings inside city centres have suffered changes in their use, becoming cultural, social or representative centres. This thesis attempts the analysis of the constructive systems employed in tobacco industrial architecture, from drying sheds to factories. The drying sheds are an example of bioclimatic industrial architecture. The factories are a typology that have successfully adapted to new uses. Industrial architecture uses a language that follows the advances in industrialization, anticipating new materials and structures, and merging the complex relationships established among products, human beings, space and locations. These buildings were promoted extensively in the country. They are characterized by technological architectural sociological and landscaping innovations. They are considered as important examples of the evolution and the implementation of construction techniques (building materials and structures). They are also considered as examples of innovation in the building typology, in their economic structure and in the technologies that they have applied. The settings in which the drying sheds are placed have an important influence in them. They cannot be considered as isolated elements. Instead, there is a close relationship between drying sheds and the surroundings in which they are located. Drying sheds’ hygrotermal and environmental conditions are analyzed in this thesis to compare them with the values of human comfort and find suitable relationships and parameters. All the drying sheds that have been analyzed are constructed with brick. This implies a consideration of “zero degree” for both the construction and the composition of the architectural process. The detailing - entails making all the accumulative processes explicit as the brick walls are left exposed. This minimal component allows a wide range of options that are never random but based on the logic of the way in which it is combined. The “sincerity” in the exposition of material, displaying them in their very nature and showing how they are really used, is a basic characteristic of industrial architecture, and it is even more expressive in these types of buildings. The walls of the drying sheds undergo a permeability assessment in order to determine the degree of ventilation and orientation, the lattice pattern used and the overall volume. This specific conditioning system can serve as a resource for other buildings, and consequently, it could be transferred to other uses within a two-pronged approach: -Climatically adapted architecture that takes into account the surroundings. -Architecture as a generator of specific climatic conditions indoors. Drying sheds’ main purposes / aims deal with how to provide shade, ventilation and a covered space as well as permeability. The industrial architecture must be recognized as historical valuable buildings due to its intrinsic and distinctive characteristics. Knowing the productive structure, allow us to make a proper analysis of these buildings, since the basic aim, is to understand the spatial organization indoors. Factories did not come close to the tobacco production, with the exception of Cádiz and Palazuelo, where there are sheds and tobacco croplands nearby. The main reason for this separation is that the process of obtaining tobacco has two processes: the primary process and the secondary process. In the primary process tobacco leaves are left to dry. In the secondary process, previously manufactured tobacco allocated in the factories where the weather conditions are not important. This fact determines that in the climate areas where this study tales place there are some cases in which we can find both factories and drying sheds, and others where there are either factories or drying sheds only. The location of these factories met various demands, being the most outstanding the ones related to geographic, strategic and political reasons. In most factories the choice of its location was often linked to the incoming of raw goods, mainly delivered through waterways –it is the case of Seville,) and by land, using railways. The location of the factories was linked to political reasons in only two cases Madrid and Logroño, which are the only ones that are not placed near the coast. The one in Madrid was built due to its political centrality and because geographically speaking, it was the reference landmark of means of land and rail transports. Many factories, in fact, were settled nearby rail stations. For the factory in Logroño, only political reasons were taken into consideration. I should like to close by undertaking a comparative study of factories in Seville, Madrid and San Sebastian. There are a number of reasons to substantiate this choice: -The factory in Seville was historically speaking the first that was built and the most important one. -The factory in Madrid was the most important one administratively. This factory was the headquarters as well as being, after Seville, the one which provided a model for other factories. -The factory in San Sebastian is the biggest in the North of Spain. The analysis carried out are related to the volume of the buildings and the surface areas of the courtyards, the surface of the roofs, the permeability of the walls and the openings of the façade, the orientation and the sun exposure, the indoor spatial distribution and organization and evolution of the uses (formerly and currently) I observe that in most of these factories there has been a change in the use of the buildings, from industrial cultural purposes. These buildings can be considered as adaptable infrastructures based on a combination of architectural practicability, sustainability and functionality.

NEMAWASHI: Attaining Value Stream alignment within Complex Organizational Networks

In the process of value creation, organizations perform an intense intra-organizational dialog through which internal VS alignment is achieved towards certain strategic objectives. Within the context of complex organizational networks, were goal conflicts are preprogrammed through incentive structures, VS alignment as legitimation of action towards strategic goals has special interest. On the one hand it facilitates the access to necessary resources for goal achievement and on the other it increases the sustainability and supports commonly agreed upon decisions leading to success. This paper provides a winnerless process (WLP) differential equations model for quantifying intra-organizational value stream (VS) alignment dynamics that can help design sustainable lean management solutions. This paper presents ongoing research results that show how the model was implemented in one industrial facility.
