La transformación de la fachada en la arquitectura del siglo XX : evolución de los elementos arquitectónicos hacia el espacio

Esta tesis doctoral, bajo el título “La transformación de la fachada en la arquitectura del siglo XX. Evolución de los elementos arquitectónicos hacia el espacio único”, examina –siguiendo el método deductivo mediante investigación documental y de campo– los principales mecanismos proyectuales que han originado una transformación arquitectónica en la fachada. El término fachada, leído normalmente como sinónimo de arquitectura, ha sido analizado bajo taxonomías historiográficas, sociopolíticas, formales, compositivas o materiales. Más allá de estas clasificaciones, esta investigación determina cómo han evolucionado los elementos arquitectónicos hacia el espacio único, transformando con ello tanto la realidad física como el concepto de fachada. Proyectar, como diría Robert Venturi1. 1966, tanto desde el exterior al interior como desde el interior al exterior, produce las tensiones necesarias que ayudan a generar la arquitectura. De ahí la importancia del estudio de la transformación de la fachada como faccia, máscara, disfraz o sistema de representación, a la fachada como un diafragma activo, como un espacio de relación o como un límite donde se produce una experiencia arquitectónica con nuevos significados. El término fachada, del latín facies y del italiano facciata, fue creado como tal durante el siglo XVI, aunque como elemento arquitectónico es una realidad clásica y un concepto humanista reinventado en el Renacimiento. A principios del siglo XX la fachada se transforma radicalmente, con la aparición del vidrio plano de grandes dimensiones, y se despoja de su carga historicista. La transparencia literal hace desaparecer (negar) la fachada. La fachada se construye con nuevos materiales, nuevas tecnologías, y responde a un espacio global que espera a ser colonizado por una sociedad en constante mutación; un espacio que irá siendo cada vez más complejo a lo largo del siglo pasado y que tendrá como una de sus principales consecuencias un mayor grado de abstracción en la fachada. Para desarrollar con mayor precisión las intenciones de este trabajo se analiza la acepción de fachada en la que se encuadra la línea de investigación de la tesis doctoral. Siguiendo las indicaciones del Profesor Kenneth Frampton, se ha optado por dedicar precisamente a este análisis el primer capítulo, de precedentes, con el fin de hacer una relectura de la fachada barroca en clave contemporánea. La fachada barroca se estudia como un punto de inflexión, y origen de la transformación, frente al clasicismo de siglos precedentes. Se plantea por tanto como el primero de los mecanismos proyectuales motivo de estudio. Estos mecanismos han sido sometidos a una clasificación que responde a diversos tipos de espacio arquitectónico que han provocado la transformación de la fachada, analizando cada uno de ellos con un filtro bajo el cual se ha desarrollado un estudio pormenorizado. De esta manera se examinan la transformación compositiva de la fachada por medio del espacio dinámico (capítulo 00_precedentes) en San Carlo alle Quattro Fontane de Francesco Borromini, la transformación constructiva de la fachada por medio del espacio membrana (capítulo 01) en la Villa Tugendhat de Mies van der Rohe, la transformación diagramática de la fachada por medio del espacio pliegue (capítulo 02) en la terminal portuaria de Yokohama de FOA, la transformación tecnológica de la fachada por medio del espacio estructura (capítulo 03) en la mediateca de Sendai de Toyo Ito y, finalmente, la transformación fenomenológica de la fachada por medio del espacio múltiple (capítulo 04) en el pabellón de vidrio del Museo Toledo de SANAA. La investigación se completa con el análisis de una serie de textos que acompañan a cada uno de los capítulos, generando así un cuerpo de conocimiento global junto al análisis documental y las visitas de campo de cada uno de los casos de estudio considerados. ABSTRACT This doctoral thesis entitled “The Transformation of the Façade in Twentieth Century Architecture. The Evolution of Architectural Elements Towards a Single Space“ employs a deductive methodology incorporating both archival and field research, to examine the main design strategies that have given rise to the architectural transformation of the façade. The term façade, usually read as a synonym for architecture, has been analyzed under historiographic, sociopolitical, formal, compositive and material taxonomies. Far beyond these classifications, this study determines how architectural elements have evolved towards a single space, consequently transforming both the physical reality and the concept of façade. As Robert Venturi would say,1 to design from the inside-out and from the outside-in can create valid tensions that help generate architecture, hence the importance of this study of the transformation of the façade as a faccia, a mask, disguise or representation system, to the façade as an active diaphragm, a connective space or a limit within which architectural events with new meaning take place. The term fachada (Spanish for façade), from the Latin facies and the Italian facciata, appeared as such during the sixteenth century, although as an architectural element it is a classical ingredient and a humanist concept reinvented during the Renaissance. At the beginning of the 20th century, the façade is radically transformed with the introduction of large format plate glass, stripping it of its historicist content. Literal transparency causes the façade to disappear. The façade is built with new materials, new technologies, responding to a global space to be occupied by an everchanging society. It is a space that becomes increasingly more complex throughout the last century and which will have, as a consequence, a larger degree of abstraction in the façade. In order to more precisely focus this investigation, the meaning of the façade has been scrutinized. Following Professor Kenneth Frampton’s advice, the first chapter -Precedents- is precisely dedicated to this analysis, in order to understand the baroque façade read in a contemporary manner. The baroque façade has been studied as a turning point, the origin of the transformation of the façade, as compared to the classicism of previous centuries. For this reason it is considered the first design strategy to be studied. These strategeies have been sorted into a classification of architectural spaces that have caused the transformation of the façade, all of which having been analyzed using a methodology allowing for detailed study. Thus, this investigation examines the compositional transformation of the façade by means of a dynamic space (chapter 00: Precedents) in San Carlo alle Quattro Fontane by Francesco Borromini, the constructive transformation of the façade by means of a membrane space (chapter 01) in the Tugendhat Villa by Mies van der Rohe, the diagrammatic transformation of the façade by means of a folded space (chapter 02) in the Yokohama International Port Terminal by FOA, the technological transformation of the façade by means of a structure space (chapter 03) in the Sendai Mediathèque by Toyo Ito, and finally, the technological transformation of the façade by means of multiple space (chapter 04) in the Glass Pavilion of the Toledo Museum of Art by SANAA. The research is supplemented by the analysis of a series of texts presented alongside each chapter; creating a global body of knowledge together alongside the documentary analysis and on site analysis of each of the case studies considered.

Creating Beautiful Art: Challenging Comfort

Creating Beautiful Art: Challenging Comfort investigates the notion of beauty and its relationship to art while asking what is and can be art. Throughout the work, research supports the concept of beauty elevating art even with the use of atypical, unconventional, or mundane materials. Direct attention is given to this idea by completion of a Creative Capstone Project. I incorporated aesthetics with unconventional materials in order to challenge viewing comfort, as well as added value to the existing body of knowledge concerning beauty in contemporary art. The reflective section summarizes the importance of unconventional materials creating beauty in art in order to progress itself linearly by creating and reinventing the new.

IR as Practical Philosophy: Defining a 'Classical Approach'

This article addresses the centrality of normativity to IR (International Relations) by engaging in an investigation of the meaning of a 'classical' approach (Bull 1969). It demonstrates how a classical approach, properly understood, might provide common ground for IR theorists. The substantive argument is that IR can benefit from reflection on the classical understanding of the relationship between theory and practice, and in particular on the understanding of this relationship provided by philosophical hermeneutics. Philosophical hermeneutics is an approach to the human sciences informed by Aristotle's conception of a practical philosophy. A practical philosophy in the classical sense sees theory as a moral and political inquiry involving a body of knowledge and a philosophy of practice engaging in reflection upon the nature of the good life and the means to achieve it.

Designing and managing collaborative enterprises in the automotive industry

This paper presents the findings of a recently completed research project. It sheds light upon the appropriate governance of inter-firm relationships, in order to achieve competitive success for the whole partnership and its individual members. An exploratory study in the German automotive industry using inductive Grounded Theory was conducted, in order to form a set of propositions that were then validated. The research has resulted in the consolidation of these propositions into a novel concept termed Collaborative Enterprise Governance, which draws on an inter-disciplinary body of knowledge. The core of the concept is a competence based contingency framework that helps enterprise managers in selecting the most appropriate governance strategy (i.e. enterprise structure) for an inter-firm relationships within automotive supply networks (i.e. enterprises), depending on various exogenous and endogenous factors.

Decision-making algorithms in geometric modelling

Many of the applications of geometric modelling are concerned with the computation of well-defined properties of the model. The applications which have received less attention are those which address questions to which there is no unique answer. This thesis describes such an application: the automatic production of a dimensioned engineering drawing. One distinctive feature of this operation is the requirement for sophisticated decision-making algorithms at each stage in the processing of the geometric model. Hence, the thesis is focussed upon the design, development and implementation of such algorithms. Various techniques for geometric modelling are briefly examined and then details are given of the modelling package that was developed for this project, The principles of orthographic projection and dimensioning are treated and some published work on the theory of dimensioning is examined. A new theoretical approach to dimensioning is presented and discussed. The existing body of knowledge on decision-making is sampled and the author then shows how methods which were originally developed for management decisions may be adapted to serve the purposes of this project. The remainder of the thesis is devoted to reports on the development of decision-making algorithms for orthographic view selection, sectioning and crosshatching, the preparation of orthographic views with essential hidden detail, and two approaches to the actual insertion of dimension lines and text. The thesis concludes that the theories of decision-making can be applied to work of this kind. It may be possible to generate computer solutions that are closer to the optimum than some man-made dimensioning schemes. Further work on important details is required before a commercially acceptable package could be produced.

Rough-terrain groundspeed measurement:a radar-based commercial solution

Off-highway motive plant equipment is costly in capital outlay and maintenance. To reduce these overheads and increase site safety and workrate, a technique of assessing and limiting the velocity of such equipment is required. Due to the extreme environmental conditions met on such sites, conventional velocity measurement techniques are inappropriate. Ogden Electronics Limited were formed specifically to manufacture a motive plant safety system incorporating a speed sensor and sanction unit; to date, the only such commercial unit available. However, problems plague the reliability, accuracy and mass production of this unit. This project assesses the company's exisiting product, and in conjunction with an appreciation of the company history and structure, concludes that this unit is unsuited to its intended application. Means of improving the measurement accuracy and longevity of this unit, commensurate with the company's limited resources and experience, are proposed, both for immediate retrofit and for longer term use. This information is presented in the form of a number of internal reports for the company. The off-highway environment is examined; and in conjunction with an evaluation of means of obtaining a returned signal, comparisons of processing techniques, and on-site gathering of previously unavailable data, preliminary designs for an alternative product are drafted. Theoretical aspects are covered by a literature review of ground-pointing radar, vehicular radar, and velocity measuring systems. This review establishes and collates the body of knowledge in areas previously considered unrelated. Based upon this work, a new design is proposed which is suitable for incorporation into the existing company product range. Following production engineering of the design, five units were constructed, tested and evaluated on-site. After extended field trials, this design has shown itself to possess greater accuracy, reliability and versatility than the existing sensor, at a lower unit cost.

Surviving the global economic crisis in the automotive industry through sustainable supplier management

This chapter looks at how the current global economic crisis has impacted upon the global automotive industry from an operations and supply chain perspective. It presents an empirical and theoretical background to help long and short term planning for organisations experiencing adverse trading conditions. The empirical research study (conducted between 2004-07 primarily in Germany) revealed that organisations are able to make short term improvements to performance by reducing costs and making process and structural improvements, but in the long term the deeper rooted causes of the industry can in part only be dealt with by improving interfirm R&D collaborations based upon competencies rather than cost related issues. A new approach known as Collaborative Enterprise Governance is presented which supports the design and management of competitive sustainable enterprises; it consists of a data capture tool, a body of knowledge and a dynamic reference grid to show how many part-to-part company relationships can exist simultaneously to make up productprocess focused enterprises. Examples from the German automotive industry are given, impact upon the overall product development lifecycle and the implications for organisational strategists are discussed. © 2010 Nova Science Publishers, Inc.

Managing risk in enterprise resource planning projects

Enterprise Resource Planning (ERP) projects are strategic and capital intensive, so failure may be costly and even cause bankruptcy of companies. Previous studies have proposed ways for improving implementation, but they are mostly generic and follow standardized project management practices as specified in various standards (e.g. the “project management body of knowledge” of the Project Management Institute). Because ERP is interdisciplinary (involving change management, project management and information technology management), it warrants a customized approach to managing risks throughout the life cycle of implementation and operation. Through a practical case study, this paper demonstrates a qualitative, user friendly approach to ERP project risk management. Firstly, through a literature review it identifies various risk factors in ERP implementation. Secondly, the risk management practices of a UK-based multinational consulting company in one of its clients are evaluated. The risk factors from the case study organization and literature are then compared and discussed.

Integrating skills profiling and purchasing portfolio management:an opportunity for building purchasing capability

Kralijc’s (1983) purchasing portfolio approach holds that different types of purchases need different sourcing strategies, underpinned by distinct sets of resources and practices. The approach is widely deployed in business and extensively researched, and yet little research has been conducted on how knowledge and skills vary across a portfolio of purchases. This study extends the body of knowledge on purchasing portfolio management, and its application in the strategic development of purchasing in an organization, and on human resource management in the purchasing function. A novel approach to profiling purchasing skills is proposed, which is well suited to dynamic environments which require flexibility. In a survey, experienced purchasing personnel described a specific purchase and profiled the skills required for effective performance in purchasing that item. Purchases were categorized according to their importance to the organization (internally-oriented evaluation of cost and production factors) and to the supply market (externally-oriented evaluation of commercial risk and uncertainty). Through cluster analysis three key types of purchase situations were identified. The skills required for effective purchasing vary significantly across the three clusters (for 22 skills, p<0.01). Prior research shows that global organizations use the purchasing portfolio approach to develop sourcing strategies, but also aggregate analyses to inform the design of purchasing arrangements (local vs global) and to develop their improvement plans. Such organizations would also benefit from profiling skills by purchase type. We demonstrate how the survey can be adapted to provide a management tool for global firms seeking to improve procurement capability, flexibility and performance.

SME resilience to extreme weather events:important initiatives for informing policy making in the area

Enhancing the resilience of local communities to weather extremes has gained significant interest over the years, amidst the increased intensity and frequency of such events. The fact that such weather extremes are forecast to further increase in number and severity in future has added extra weight to the importance of the issue. As a local community consists of a number of community groups such as households, businesses and policy makers, the actions of different community groups in combination will determine the resilience of the community as a whole. An important role has to be played by Small and Medium-sized Enterprises (SMEs); which is an integral segment of a local community in the UK, in this regard. While it is recognised that they are vital to the economy of a country and determines the prosperity of communities, they are increasingly vulnerable to effects of extreme weather. This paper discusses some of the exploratory studies conducted in the UK on SMEs and their ability to cope with extreme weather events, specifically flooding. Although a reasonable level of awareness of the risk was observed among the SMEs, this has not always resulted in increased preparedness even if they are located in areas at risk of flooding. The attitude and the motivation to change differed widely between SMEs. The paper presents schemas by which the SMEs can identify their vulnerability better so that they can be populated among a community of SMEs, which can be taken forward to inform policy making in this area. Therefore the main contribution the paper makes to the body of knowledge in the area is a novel way to communicate to SMEs on improving resilience against extreme weather, which will inform some of the policy making initiatives in the UK.

Creative leadership:a multi-context conceptualization

Various streams of organizational research have examined the relationship between creativity and leadership, albeit using slightly different names such as “creative leadership”, “leading for creativity and innovation”, and “managing creatives”. In this article, we review this dispersed body of knowledge and synthesize it under a global construct of creative leadership, which refers to leading others toward the attainment of a creative outcome. Under this unifying construct, we classify three more narrow conceptualizations that we observe in the literature: facilitating employee creativity; directing the materialization of a leader's creative vision; and integrating heterogeneous creative contributions. After examining the contextual characteristics associated with the three conceptualizations, we suggest that they represent three distinct collaborative contexts of creative leadership. We discuss the theoretical implications of a multi-context framework of creative leadership, especially in terms of resolving three persisting problems in the extant literature: lack of definitional clarity, shortage of nuanced theories, and low contextual sensitivity.

Investigating factors influencing local government decision makers while adopting integration technologies (IntTech)

The emergence of innovative and revolutionary Integration Technologies (IntTech) has highly influenced the local government authorities (LGAs) in their decision-making process. LGAs that plan to adopt such IntTech may consider this as a serious investment. Advocates, however, claim that such IntTech have emerged to overcome the integration problems at all levels (e.g. data, object and process). With the emergence of electronic government (e-Government), LGAs have turned to IntTech to fully automate and offer their services on-line and integrate their IT infrastructures. While earlier research on the adoption of IntTech has considered several factors (e.g. pressure, technological, support, and financial), inadequate attention and resources have been applied in systematically investigating the individual, decision and organisational context factors, influencing top management's decisions for adopting IntTech in LGAs. It is a highly considered phenomenon that the success of an organisation's operations relies heavily on understanding an individual's attitudes and behaviours, the surrounding context and the type of decisions taken. Based on empirical evidence gathered through two intensive case studies, this paper attempts to investigate the factors that influence decision makers while adopting IntTech. The findings illustrate two different doctrines - one inclined and receptive towards taking risky decisions, the other disinclined. Several underlying rationales can be attributed to such mind-sets in LGAs. The authors aim to contribute to the body of knowledge by exploring the factors influencing top management's decision-making process while adopting IntTech vital for facilitating LGAs' operational reforms.
