Monitoring the impact of sea storms on coastal areas is fundamental to study beach evolution and the vulnerability of low-lying coasts to erosion and flooding. Modelling wave runup on a beach is possible, but it requires accurate topographic data and model tuning, that can be done comparing observed and modeled runup. In this study we collected aerial photos using an Unmanned Aerial Vehicle after two different swells on the same study area. We merged the point cloud obtained with photogrammetry with multibeam data, in order to obtain a complete beach topography. Then, on each set of rectified and georeferenced UAV orthophotos, we identified the maximum wave runup for both events recognizing the wet area left by the waves. We then used our topography and numerical models to simulate the wave runup and compare the model results to observed values during the two events. Our results highlight the potential of the methodology presented, which integrates UAV platforms, photogrammetry and Geographic Information Systems to provide faster and cheaper information on beach topography and geomorphology compared with traditional techniques without losing in accuracy. We use the results obtained from this technique as a topographic base for a model that calculates runup for the two swells. The observed and modeled runups are consistent, and open new directions for future research.

F2TE3: A Transparent semi-monocoque VIP Envelope

This article examines a new lightweight, slim, high energy efficient, light-transmitting, self-supporting envelope system, providing for seamless, free-form designs for use in architectural projects. The system exploits vacuum insulation panel technology. The research was based on envelope components already existing on the market and patents and prototypes built by independent laboratories, especially components implemented with silica gel insulation, as this is the most effective transparent thermal insulation there is today. The tests run on these materials revealed that there is not one that has all the features required of the new envelope model, although some do have properties that could be exploited to generate this envelope, namely, the vacuum chamber of vacuum insulation panels, the use of monolithic aerogel as insulation in some prototypes, and reinforced polyester barriers. These three design components have been combined and tested to design a new, variable geometry, energy-saving envelope system that also solves many of the problems that other studies ascribe to the use of vacuum insulation panels.

Free-Form, High Energy Performance, Transparent Envelope

This article examines, from the energy viewpoint, a new lightweight, slim, high energy efficient, light-transmitting envelope system, providing for seamless, free-form designs for use in architectural projects. The research was based on envelope components already existing on the market, especially components implemented with granular silica gel insulation, as this is the most effective translucent thermal insulation there is today. The tests run on these materials revealed that there is not one that has all the features required of the new envelope model, although some do have properties that could be exploited to generate this envelope, namely, the vacuum chamber of vacuum insulated panels (VIP), the monolithic aerogel used as insulation in some prototypes, reinforced polyester barriers. By combining these three design components — the high-performance thermal insulation of the vacuum chamber combined with monolithic silica gel insulation, the free-form design potential provided by materials like reinforced polyester and epoxy resins—, we have been able to define and test a new, variable geometry, energy-saving envelope system.

Parque eólico offshore en San Pedro de Alcántara

El principal motivo de implantar un parque eólico de estas características es responder a una necesidad palpable en el ámbito mundial como es el crecimiento en la demanda energética unido a un agotamiento de los recursos petrolíferos. Si a esto le sumamos la tendencia actual que han adquirido muchos países de oponerse al desarrollo de nuevas centrales nucleares tras el desastre ocurrido en Fukushima (Japón), y el aumento de los niveles de contaminación en las principales ciudades europeas, así como la sobreexplotación de los parques eólicos onshore en la Península Ibérica, configuran un marco perfecto para el despegue definitivo de la energía eólica offshore como alternativa perfecta al resto de fuentes de energía. Desde el punto de vista particular a nuestra localización, existe una demanda energética considerable, dado el carácter turístico de nuestro emplazamiento, que queda de manifiesto en el Plan General de Ordenación Urbana de Marbella, por lo que el objetivo de este proyecto será abastecer energía a San Pedro Alcántara y las poblaciones vecinas, a fin de que no se produzca ninguna carencia energética a lo largo de los periodos estivales, que serán los momentos de mayor demanda solicitada.

Central de ciclo combinado de Lemóiz

El presente proyecto desarrolla el diseño de un central de ciclo combinado de 800MW de potencia nominal y establece los parámetros para su construcción. La central se ha diseñado con una configuración 1×1, es decir, turbina de gas, generador y turbina de vapor engranadas en un mismo eje, constituyendo un grupo de potencia de 400MW. La central se compone de dos de estos grupos, alimentado cada uno por una caldera de recuperación. La evacuación de gases de combustión se efectúa por medio de una chimenea de 13m de diámetro interior y 80m de altura, fabricada en hormigón armado. El circuito de refrigeración abierto, vertiendo directamente el agua de refrigeración al mar, se ha diseñado para producir un impacto mínimo sobre el medio marino. Se ha proyectado para aprovechar todo lo posible las estructuras existentes en el emplazamiento, pertenecientes a la construcción de la Central Nuclear de Lemóiz. No se ha considerado necesario para la construcción de la central demoler los edificios de la central nuclear, por haber espacio suficiente en la explanada adyacente. Se reducen así los costes de acondicionamiento del terreno.
