Energy and economic survey of the renovation of a residential building wall in Madrid

La edificación es un sector de enorme influencia en la evolución del consumo de energía y las emisiones de CO2. Teniendo en cuenta que en estos momentos hay 3,5 millones de viviendas vacías y que los próximos años no va a haber un aumento en la demanda de vivienda nueva, la rehabilitación sostenible del parque residencial existente es una tarea prioritaria y sobre la que hay que prestar especial interés. Dado que aún queda mucho donde actuar, es necesario hacer una reflexión sobre cómo se está rehabilitando para poder mejorar en el futuro. Por ello, el objetivo del presente trabajo es analizar algunas estrategias adoptadas hasta ahora en el parque inmobiliario y su aplicación en un caso de estudio, mediante la mejora de la fachada de un edificio de viviendas situado en Madrid.

Sostenibilidad de los biocombustibles para autoconsumo en un entorno rural

Se busca relacionar dos sectores que sin tener a priori nada en común, pueden verse beneficiados por una solución que mejore la situación de ambos. Hablamos del sector biocombustibles y del sector algodonero español. El sector de los biocombustibles ha visto un desarrollo espectacular en los últimos diez años, empujado por fuertes políticas gubernamentales. En general estas políticas buscan satisfacer una necesidad, la energía, mediante fórmulas que supongan un menor impacto medioambiental que las actuales. También una disminución de la dependencia exterior para el suministro de energía y otras ventajas. El sector algodonero español es un sector tradicional, que subsiste gracias a las ayudas europeas, y que se ha visto fuertemente afectado por las reformas de esas subvenciones. Se caracteriza por estar en vías de amortizar fuertes inversiones en regadío, por ser viable en suelos con alta salinidad, y por el clima propio del sur de España. Al ser un cultivo no alimentario, se evita la controversia que suscita la producción de cultivos energéticos en suelos factibles de ser usados para producción alimentaria. Se propone la sustitución del algodón por el ricino, cultivo muy experimentado en otros países (Colombia, Ecuador, Argentina, Brasil, Chile e India) y que tendría buena acogida en la tierra andaluza. Se analizan las características del nuevo cultivo y su adecuación para esta región. Se estudian los procesos necesarios para la extracción del aceite y su procesamiento a biodiesel, con el dimensionamiento de los equipos necesarios. Por último, se realiza un estudio económico de la propuesta, haciendo hincapié en los beneficios económicos que se obtienen por la vía del ahorro, tanto en ayudas de la PAC (Política Agraria Común) de la UE (Unión Europea), cómo por la disponer de un producto, biodiesel, que de otro modo deberíamos satisfacer mediante la compra de combustible tradicional. Abstract This Project looks forward the relationship between two different sectors with different troubles in Spain, which could be benefited by a common solution. We are talking about biofuels and the cotton industry. The biofuels sector has been developed along the last ten years because of strong governmental policies. These policies try to find how to supply energy, with the less environmental impact, as well as to decrease the dependency of third countries, and other benefits. The Spanish cotton industry is traditional, it has survived because of the European grants, and it is passing through an uncertain scenario because of the alteration of these grants. It is characterized by the non amortized investment in irrigation, by the high salinity ratio in the ground (which means that is unable for a number of crops), and by weather of this Spanish region. As well as cotton is not a food crop, the controversial of to plant energetic crops in areas able to produce food is avoided. It is aimed to replace cotton with castor, an oilseed which has been experienced in other countries (Colombia, Ecuador, Argentina, Brazil, Chile e India) and which could be accepted in that ground. It is analyzed the main features of the new drop and its ability to be planted in this area. The processes to obtain the oil and then the biofuel are studied. The equipment is sized. At least, it is developed an economic survey about the proposal, deepening in the benefits which are obtained because of savings, in European grants and in diesel.

Survey and brain storming studies about machines, constructions, human and environmental risk consideration in the careers of the Universidad Politécnica of Madrid

The Universidad Politécnica of Madrid (UPM) includes schools and faculties that were for engineering degrees, architecture and computer science, that are now in a quick EEES Bolonia Plan metamorphosis getting into degrees, masters and doctorate structures. They are focused towards action in machines, constructions, enterprises, that are subjected to machines, human and environment created risks. These are present in actions such as use loads, wind, snow, waves, flows, earthquakes, forces and effects in machines, vehicles behavior, chemical effects, and other environmental factors including effects of crops, cattle and beasts, forests, and varied essential economic and social disturbances. Emphasis is for authors in this session more about risks of natural origin, such as for hail, winds, snow or waves that are not exactly known a priori, but that are often considered with statistical expected distributions giving extreme values for convenient return periods. These distributions are known from measures in time, statistic of extremes and models about hazard scenarios and about responses of man made constructions or devices. In each engineering field theories were built about hazards scenarios and how to cover for important risks. Engineers must get that the systems they handle, such as vehicles, machines, firms or agro lands or forests, obtain production with enough safety for persons and with decent economic results in spite of risks. For that risks must be considered in planning, in realization and in operation, and safety margins must be taken but at a reasonable cost. That is a small level of risks will often remain, due to limitations in costs or because of due to strange hazards, and maybe they will be covered by insurance in cases such as in transport with cars, ships or aircrafts, in agro for hail, or for fire in houses or in forests. These and other decisions about quality, security for men or about business financial risks are sometimes considered with Decision Theories models, using often tools from Statistics or operational Research. The authors have done and are following field surveys about risk consideration in the careers in UPM, making deep analysis of curricula taking into account the new structures of degrees in the EEES Bolonia Plan, and they have considered the risk structures offered by diverse schools of Decision theories. That gives an aspect of the needs and uses, and recommendations about improving in the teaching about risk, that may include special subjects especially oriented for each career, school or faculty, so as to be recommended to be included into the curricula, including an elaboration and presentation format using a multi-criteria decision model.

Integration of cooperation for development in Survey Engineering curricula at the European Higher Education Area (EHEA) framework

Survey Engineering curricula involves the integration of many formal disciplines at a high level of proficiency. The Escuela de Ingenieros en Topografía, Cartografía y Geodesia at Universidad Politécnica de Madrid (Survey Engineering) has developed an intense and deep teaching on so-called Applied Land Sciences and Technologies or Land Engineering. However, new approaches are encouraged by the European Higher Education Area (EHEA). This fact requires a review of traditional teaching and methods. Furthermore, the new globalization and international approach gives new ways to this discipline to teach and learn about how to bridge gap between cultures and regions. This work is based in two main needs. On one hand, it is based on integration of basic knowledge and disciplines involved in typical Survey Engineering within Land Management. On the other, there is an urgent need to consider territory on a social and ethical basis, as far as a part of the society, culture, idiosyncrasy or economy. The integration of appropriate knowledge of the Land Management is typically dominated by civil engineers and urban planners. It would be very possible to integrate Survey Engineering and Cooperation for Development in the framework of Land Management disciplines. Cooperation for Development is a concept that has changed since beginning of its use until now. Development projects leave an impact on society in response to their beneficiaries and are directed towards self-sustainability. Furthermore, it is the true bridge to reduce gap between societies when differences are immeasurable. The concept of development has also been changing and nowadays it is not a purely economic concept. Education, science and technology are increasingly taking a larger role in what is meant by development. Moreover, it is commonly accepted that Universities should transfer knowledge to society, and the transfer of knowledge should be open to countries most in need for developing. If the importance of the country development is given by education, science and technology, knowledge transfer would be one of the most clear of ways of Cooperation for Development. Therefore, university cooperation is one of the most powerful tools to achieve it, placing universities as agents of development. In Spain, the role of universities as agents of development and cooperation has been largely strengthened. All about this work deals to how to implement both Cooperation for Development and Land Management within Survey Engineering at the EHEA framework.
