In this paper, we describe the successful results of an international research project focused on the use of Web technology in the educational context. The article explains how this international project, funded by public organizations and developed over the last two academic years, focuses on the area of open educational resources (OER) and particularly the educational content of the OpenCourseWare (OCW) model. This initiative has been developed by a research group composed of researchers from three countries. The project was enabled by the Universidad Politécnica de Madrid OCW Office�s leadership of the Consortium of Latin American Universities and the distance education know-how of the Universidad Técnica Particular de Loja (UTPL, Ecuador). We give a full account of the project, methodology, main outcomes and validation. The project results have further consolidated the group, and increased the maturity of group members and networking with other groups in the area. The group is now participating in other research projects that continue the lines developed here

Balanced scorecard to improve strategic management control at School of Mines and Energy, Universidad Politécnica de Madrid

We studied the situation in Spanish public universities regarding the use of the Balanced Scorecard (BSC), as an instrument of control and strategic management. Also, we studied its application to the School of Mines and Energy at Universidad Politécnica de Madrid. The main advantage of the BSC is that improves the organizational structure of the workplace and the achievement of the objectives that ensure long-term success. First we review the strategy for success used in the Spanish educational system and specifically in the Spanish public universities. Then using the BSC and applying the main strategic lines for the successful management of the School of Mines and Energy at Universidad Politécnica de Madrid. The strategic lines affect all the college groups and the success of the BSC tool is to increase communication between the faculties, personal auxiliary, students and society in general that make up the university. First we performed a SWOT analysis (DAFO in Spanish) there are proposed different perspectives that focus the long-term strategic objectives. The BSC is designed based on the strategic objectives that set the direction through using indicators and initiatives, the goals are achieved up to the programmed schedule. In the perspective of teaching, objectives are set to update facilities and increase partnerships with other universities and businesses, encouraging ongoing training of staff and improved coordination and internal communication. The internal process perspective aims at improving the marketing, the promotion of the international dimension of the school through strategic alliances, better mobility for students and professors and improved teaching and research quality results. It continues with improving the image of the school between customer?s perspective, the quality perceived by students and the loyalty of the teaching staff by retaining talent. Finally, the financial perspective which should contain costs without harming the quality, improving the employability of students and achieve relevant jobs at teaching and research through international measurement standards.

The Spreading of Christianity and the introduction of Modern Architecture in Shannxi, China (1840-1949): Christian churches and traditional Chinese architecture

La arquitectura china ha experimentado grandes cambios a lo largo de un extenso proceso histórico. El hito de mayor importancia es el que da paso al denominado Tiempo Moderno, periodo en el cual irrumpe por vez primera en China la arquitectura occidental, que comienza a tener una influencia muy activa y significativa sobre los rasgos y la identidad de la arquitectura tradicional china, hasta ese momento el único estilo o forma de hacer –muy diferente, en cuanto a su concepción y fisonomía, de los planteamientos occidentales- que había sobrevivido sin desvíos significativos, configurando un panorama milenario bastante homogéneo en los aspectos técnicos y artísticos en el desarrollo de esa arquitectura. Por un cúmulo de complejas razones, la mayor parte de la arquitectura china del periodo feudal -es decir el que forman todos los años anteriores a 1849- ha desaparecido. Sin embargo, desde la fecha indicada hasta la Revolución de 1949 (el denominado periodo semicolonial o semifeudal), sí se conservan muchas edificaciones, que fueron mejor construidas y mantenidas luego, destacando por su importancia en ese sentido las iglesias cristianas. Dichos templos representan cronológicamente, no sólo la primera irrupción de la arquitectura clásica occidental en China, sino el inicio de un proceso de modernización de la profundamente enraizada y, en buena medida, estancada arquitectura vernácula, combinando técnicas y estilos de ambos planteamientos, para dar como resultado originales edificaciones de un singular eclecticismo que caracterizarían buena parte de la arquitectura de dicha etapa semicolonial. En términos generales, últimamente se ha ido prestando cada vez más atención a esta arquitectura de los tiempos modernos, aunque las iglesias cristianas de la provincia de Shaanxi no han sido objeto de estudio específico, a pesar de que su tipología es muy representativa de las construcciones de esta clase en otras regiones del interior de China. La investigación que desarrolla la presente tesis doctoral sale al paso de esa deficiencia, abriendo puertas a la continuación del trabajo referido, extendido a otras zonas o arquitecturas, y, por extensión, a la profundización analítica de la hibridación arquitectónica y cultural entre China y Occidente. Sobre las bases de investigación documental, estudios de campo y dibujo, la tesis plantea un estudio aclaratorio de los rasgos y raíces de la arquitectura tradicional china, al que sigue otro histórico y tipológico de los templos cristianos en la provincia de Shaanxi, deteniéndose en sus características fundamentales, situación (uso) actual y estado de conservación. Se ha considerado imprescindible añadir al trabajo, como apéndice, un elaborado glosario conceptual ilustrado de términos básicos arquitectónicos y constructivos, en chino, inglés y español. ABSTRACT The Chinese architecture has gone through great changes during the long process of history. The tremendous changing period was the named Modern Times of China when, for the very first time, the western architecture was introduced into China and became to influence majorly on the traditional Chinese architecture. Before that, the traditional Chinese architecture which has its own, yet totally different system from the occidental architecture system was the only architectural style could be found in China. Although, due to many historical, conceptual and architectural characteristic reasons, large amount of the ancient Chinese architecture built in the feudal China was not preserved, there are a lot of buildings of semi-feudal China that was well constructed and conserved. The most important architectural type of the semi-feudal China is the Christian Churches. It was not only the first western architectural form that was brought into and well developed in China, but also was the beginner of the modernization process of Chinese architecture. Because of the deep root of the 2000-year traditional Chinese architecture, all the Christian Churches built in China during the semi-colonial society has a combined style of both the traditional Chinese architecture and the classic western churches. They are a priceless asset of the Chinese architectural history. Recently, more and more attention had been paid on the Chinese Modern Times architecture, however, the Christian Churches in Shaanxi Province, the province which has a unique history with the Christian, but less economically developed have never been researched yet. The Christian Churches of Shaanxi Province reflect the general feature of developing history of the Christian Churches of common inner-land regions in China. The research opens the door to further study on other Christian Churches and related buildings, and also for the further study on the Chinese-western architectural and culture communication. On the base of document research, field survey and mapping, in this thesis, an in-depth study had been done on the general history of the features and roots of the traditional Chinese architecture, the developing history of the Christian Churches of Shaanxi Province and the architectural types, examples, characteristics, present situation and conservation status. By comparing the Christian Churches of the cities in Shaanxi province to the Christian Churches in other more developed cities, and by comparing the Christian Churches in China to the classic western churches, the architectural combination feature of the Christian Churches in China are highlighted. The thesis is a fundamental research on which many further studies about the architectural developing history, characteristics and conservation of the Christian Churches in China could be done. It is considered essential to add to the work, as an appendix, an elaborate conceptual illustrated glossary of architectural and construction terms in Chinese, English and Spanish.

La implementación arquitectónica de los acristalamientos activos con agua circulante, y su contribución en edificios de consumo de energía casi nulo

La presente Tesis Doctoral evalúa la contribución de una fachada activa, constituida por acristalamientos con circulación de agua, en el rendimiento energético del edificio. Con especial énfasis en la baja afección sobre su imagen, su integración ha de favorecer la calificación del edificio con el futuro estándar de Edificio de consumo de Energía Casi Nulo (EECN). El propósito consiste en cuantificar su aportación a limitar la demanda de climatización, como solución de fachada transparente acorde a las normas de la energía del 2020. En el primer capítulo se introduce el planteamiento del problema. En el segundo capítulo se desarrollan la hipótesis y el objetivo fundamental de la investigación. Para tal fin, en el tercer capítulo, se revisa el estado del arte de la tecnología y de la investigación científica, mediante el análisis de la literatura de referencia. Se comparan patentes, prototipos, sistemas comerciales asimilables, investigaciones en curso en Universidades, y proyectos de investigación y desarrollo, sobre envolventes que incorporan acristalamientos con circulación de agua. El método experimental, expuesto en el cuarto capítulo, acomete el diseño, la fabricación y la monitorización de un prototipo expuesto, durante ciclos de ensayos, a las condiciones climáticas de Madrid. Esta fase ha permitido adquirir información precisa sobre el rendimiento del acristalamiento en cada orientación de incidencia solar, en las distintas estaciones del año. En paralelo, se aborda el desarrollo de modelos teóricos que, mediante su asimilación a soluciones multicapa caracterizadas en las herramientas de simulación EnergyPlus y IDA-ICE (IDA Indoor Climate and Energy), reproducen el efecto experimental. En el quinto capítulo se discuten los resultados experimentales y teóricos, y se analiza la respuesta del acristalamiento asociado a un determinado volumen y temperatura del agua. Se calcula la eficiencia en la captación de la radiación y, mediante la comparativa con un acristalamiento convencional, se determina la reducción de las ganancias solares y las pérdidas de energía. Se comparan el rendimiento del acristalamiento, obtenido experimentalmente, con el ofrecido por paneles solares fototérmicos disponibles en el mercado. Mediante la traslación de los resultados experimentales a casos de células de tamaño habitable, se cuantifica la afección del acristalamiento sobre el consumo en refrigeración y calefacción. Diferenciando cada caso por su composición constructiva y orientación, se extraen conclusiones sobre la reducción del gasto en climatización, en condiciones de bienestar. Posteriormente, se evalúa el ahorro de su incorporación en un recinto existente, de construcción ligera, localizado en la Escuela de Arquitectura de la Universidad Politécnica de Madrid (UPM). Mediante el planteamiento de escenarios de rehabilitación energética, se estima su compatibilidad con un sistema de climatización mediante bomba de calor y extracción geotérmica. Se describe el funcionamiento del sistema, desde la perspectiva de la operación conjunta de los acristalamientos activos e intercambio geotérmico, en nuestro clima. Mediante la parametrización de sus funciones, se estima el beneficio adicional de su integración, a partir de la mejora del rendimiento de la bomba de calor COP (Coefficient of Performance) en calefacción, y de la eficiencia EER (Energy Efficiency Ratio) en refrigeración. En el recinto de la ETSAM, se ha analizado la contribución de la fachada activa en su calificación como Edificio de Energía Casi Nula, y estudiado la rentabilidad económica del sistema. En el sexto capítulo se exponen las conclusiones de la investigación. A la fecha, el sistema supone alta inversión inicial, no obstante, genera elevada eficiencia con bajo impacto arquitectónico, reduciéndose los costes operativos, y el dimensionado de los sistemas de producción, de mayor afección sobre el edificio. Mediante la envolvente activa con suministro geotérmico no se condena la superficie de cubierta, no se ocupa volumen útil por la presencia de equipos emisores, y no se reduce la superficie o altura útil a base de reforzar los aislamientos. Tras su discusión, se considera una alternativa de valor en procesos de diseño y construcción de Edificios de Energía Casi Nulo. Se proponen líneas de futuras investigación cuyo propósito sea el conocimiento de la tecnología de los acristalamientos activos. En el último capítulo se presentan las actividades de difusión de la investigación. Adicionalmente se ha proporcionado una mejora tecnológica a las fachadas activas existentes, que ha derivado en la solicitud de una patente, actualmente en tramitación. ABSTRACT This Thesis evaluates the contribution of an active water flow glazing façade on the energy performance of buildings. Special emphasis is made on the low visual impact on its image, and the active glazing implementation has to encourage the qualification of the building with the future standard of Nearly Zero Energy Building (nZEB). The purpose is to quantify the façade system contribution to limit air conditioning demand, resulting in a transparent façade solution according to the 2020 energy legislation. An initial approach to the problem is presented in first chapter. The second chapter develops the hypothesis and the main objective of the research. To achieve this purpose, the third chapter reviews the state of the art of the technology and scientific research, through the analysis of reference literature. Patents, prototypes, assimilable commercial systems, ongoing research in other universities, and finally research and development projects incorporating active fluid flow glazing are compared. The experimental method, presented in fourth chapter, undertakes the design, manufacture and monitoring of a water flow glazing prototype exposed during test cycles to weather conditions in Madrid. This phase allowed the acquisition of accurate information on the performance of water flow glazing on each orientation of solar incidence, during different seasons. In parallel, the development of theoretical models is addressed which, through the assimilation to multilayer solutions characterized in the simulation tools EnergyPlus and IDA-Indoor Climate and Energy, reproduce the experimental effect. Fifth chapter discusses experimental and theoretical results focused to the analysis of the active glazing behavior, associated with a specific volume and water flow temperature. The efficiency on harvesting incident solar radiation is calculated, and, by comparison with a conventional glazing, the reduction of solar gains and energy losses are determined. The experimental performance of fluid flow glazing against the one offered by photothermal solar panels available on the market are compared. By translating the experimental and theoretical results to cases of full-size cells, the reduction in cooling and heating consumption achieved by active fluid glazing is quantified. The reduction of energy costs to achieve comfort conditions is calculated, differentiating each case by its whole construction composition and orientation. Subsequently, the saving of the implementation of the system on an existing lightweight construction enclosure, located in the School of Architecture at the Polytechnic University of Madrid (UPM), is then calculated. The compatibility between the active fluid flow glazing and a heat pump with geothermal heat supply system is estimated through the approach of different energy renovation scenarios. The overall system operation is described, from the perspective of active glazing and geothermal heat exchange combined operation, in our climate. By parameterization of its functions, the added benefit of its integration it is discussed, particularly from the improvement of the heat pump performance COP (Coefficient of Performance) in heating and efficiency EER (Energy Efficiency Ratio) in cooling. In the case study of the enclosure in the School of Architecture, the contribution of the active glazing façade in qualifying the enclosure as nearly Zero Energy Building has been analyzed, and the feasibility and profitability of the system are studied. The sixth chapter sets the conclusions of the investigation. To date, the system may require high initial investment; however, high efficiency with low architectural impact is generated. Operational costs are highly reduced as well as the size and complexity of the energy production systems, which normally have huge visual impact on buildings. By the active façade with geothermal supply, the deck area it is not condemned. Useful volume is not consumed by the presence of air-conditioning equipment. Useful surface and room height are not reduced by insulation reinforcement. After discussion, water flow glazing is considered a potential value alternative in nZEB design and construction processes. Finally, this chapter proposes future research lines aiming to increase the knowledge of active water flow glazing technology. The last chapter presents research dissemination activities. Additionally, a technological improvement to existing active facades has been developed, which has resulted in a patent application, currently in handling process.

A first approach to earthquake damage estimation in Haiti: advices to minimize the seismic risk

This study is in the frame of the cooperative line that several Spanish Universities and other foreign partners started with the Haitian government in 2010. According to our studies (Benito et al. in An evaluation of seismic hazard in La Hispaniola, after the 2010 Haiti earthquake, 33rd General Assembly of the European Seismological Commission, Moscow, Russia, 2012) and recent scientific literature, the earthquake hazard in Haiti remains high (Calais et al. in Nat Geosci 3:794–799, 2010). In view of this, we wonder whether the country is currently ready to face another earthquake. In this sense, we estimated several damage scenarios in Port-au-Prince and Cap-Haitien associated to realistic possible major earthquakes. Our findings show that almost 50 % of the building stock of both cities would result uninhabitable due to structural damage. Around 80 % of the buildings in both cities have reinforced concrete structure with concrete block infill; however, the presence of masonry buildings becomes significant (between 25 and 45 % of the reinforced concrete buildings) in rural areas and informal settlements on the outskirts, where the estimated damage is higher. The influence of the soil effect on the damage spatial distribution is evident in both cities. We have found that the percentage of uninhabitable buildings in soft soil areas may be double the percentage obtained in nearby districts located in hard soil. These results reveal that a new seismic catastrophe of similar or even greater consequences than the 2010 Haiti earthquake might happen if the earthquake resilience is not improved in the country. Nowadays, the design of prevention actions and mitigation policies is the best instrument the society has to face seismic risk. In this sense, the results of this research might contribute to define measures oriented to earthquake risk reduction in Haiti, which should be a real priority for national and international institutions.
