Archivo Eduardo Torroja. La sede del itcc (1949-1953). Inéditos anteproyectos previos a su construcción

El contenido de este artículo representa el eslabón que falta en la historia publicada por la revista Informes de la Construcción sobre el proyecto y construcción de la nueva sede del Instituto, que fue el hábitat de investigación más innovador jamás construido por la Modernidad. Su difusión completa y cierra esta historia, a la vez que potencia el mensaje que Eduardo Torroja quiso transmitir agrupando los artículos que relatan esta historia, bajo un mismo título común; “El Instituto es Así”, seguramente porque durante mucho tiempo (1949-1953), defendió que no podía ser de otra manera.

Presentación [del libro "De la construcción a la ciencia. Ayer y hoy de Eduardo Torroja"]

El 27 de agosto se cumplieron los 100 años del nacimiento de Eduardo Torroja Miret (1899-1961), a cuya memoria va dedicada esta reunión conjunta de la Real Academia de Ciencias, a la que perteneció, y de la Academia de Ingeniería. La vida de Torroja transcurre en una de las etapas más agitadas de la historia española, pero también en una de las más fructíferas desde el punto de vista ingenieril. Precisamente esta sesión conjunta de la Academia de Ingeniería y de la Real Academia de Ciencias se plantea no como pura celebración hagiográfica sino como conmemoración, es decir, como oportunidad para reflexionar sobre los temas en los que Torroja tuvo la capacidad de ser precursor y para, tras recordar sus contribuciones, analizar la situación actual.

Experiences and methodology in a multidisciplinary energy and architecture competition: Solar Decathlon Europe 2012

Solar Decathlon Europe is an international competition among universities which promotes interdisciplinary learning in engineering and architecture. Students from different disciplines participate in teams guided by several professors during a 29 month preparation period plus five weeks of on-site contest. The educational project involves designing, building and testing a solar energy house connected to the electrical grid with the strategy of maximizing self-consumption, supported by bioclimatic technologies and maintaining a low environmental footprint. It culminates in a on-site contest in which teams must assembly the house themselves, test it with ordinary real life tasks and finally disassembly it. The event has also a divulgative aim, trying to make students and visitors get interested in discovering the problems presented by real engineering and architecture applications. In addition, SDE covers R&D aspects in different fields such as energy efficiency, solar energy and bioclimatic architecture. This article presents the methodology followed during the SDE 2012 edition, in which more than 850 students participated. The obtained results show that the educational competition was a success according to the technical and professional ambitions of the students, most of them considering that their knowledge had increased in areas related to technical and multidisciplinary aspects.

Passive design strategies and performance of Net Energy Plus Houses

The first step in order to comply with the European Union goals of Near to Zero Energy Buildings is to reduce the energy consumption in buildings. Most of the building consumption is related to the use of active systems to maintain the interior comfort. Passive design strategies contribute to improve the interior comfort conditions, increasing the energy efficiency in buildings and reducing their energy consumption. In this work, an analysis of the passive strategies used in Net Energy Plus Houses has been made. The participating houses of the Solar Decathlon Europe 2012 competition were used as case studies. The passive design strategies of these houses were compared with the annual simulations, and the competition monitored data, especially during the Passive Monitored Period. The analysis included the thermal properties of the building envelope, geometric parameters, ratios and others passive solutions such as Thermal Energy Storage systems, evaporative cooling, night ventilation, solar gains and night sky radiation cooling. The results reflect the impact of passive design strategies on the houses' comfort and efficiency, as well as their influence in helping to achieve the Zero Energy Buildings category.

Hardware timestamping for image acquisition system based on FlexRIO and IEEE 1588 v2 Standard

Current fusion devices consist of multiple diagnostics and hundreds or even thousands of signals. This situation forces on multiple occasions to use distributed data acquisition systems as the best approach. In this type of distributed systems, one of the most important issues is the synchronization between signals, so that it is possible to have a temporal correlation as accurate as possible between the acquired samples of all channels. In last decades, many fusion devices use different types of video cameras to provide inside views of the vessel during operations and to monitor plasma behavior. The synchronization between each video frame and the rest of the different signals acquired from any other diagnostics is essential in order to know correctly the plasma evolution, since it is possible to analyze jointly all the information having accurate knowledge of their temporal correlation. The developed system described in this paper allows timestamping image frames in a real-time acquisition and processing system using 1588 clock distribution. The system has been implemented using FPGA based devices together with a 1588 synchronized timing card (see Fig.1). The solution is based on a previous system [1] that allows image acquisition and real-time image processing based on PXIe technology. This architecture is fully compatible with the ITER Fast Controllers [2] and offers integration with EPICS to control and monitor the entire system. However, this set-up is not able to timestamp the frames acquired since the frame grabber module does not present any type of timing input (IRIG-B, GPS, PTP). To solve this lack, an IEEE1588 PXI timing device its used to provide an accurate way to synchronize distributed data acquisition systems using the Precision Time Protocol (PTP) IEEE 1588 2008 standard. This local timing device can be connected to a master clock device for global synchronization. The timing device has a buffer timestamp for each PXI trigger line and requires tha- a software application assigns each frame the corresponding timestamp. The previous action is critical and cannot be achieved if the frame rate is high. To solve this problem, it has been designed a solution that distributes the clock from the IEEE 1588 timing card to all FlexRIO devices [3]. This solution uses two PXI trigger lines that provide the capacity to assign timestamps to every frame acquired and register events by hardware in a deterministic way. The system provides a solution for timestamping frames to synchronize them with the rest of the different signals.

Eduardo Chillida, arquitecto

Es sabido que tras abandonar la carrera de arquitectura Chillida marcha a Paris a comenzar su carrera como escultor. De vuelta al País Vasco el hierro es el material en el que encuentra un camino propio. Toda la obra de su primera década está muy alejada en el aspecto formal de la arquitectura. Sin embargo, las líneas de fuerza que los hierros configuran muestran un interés espacial que queda manifiesto en una obra de 1953 denominada Consejo al espacio I. A partir de aquí su obra gira en torno al vacío. Las formas cambiarán con los materiales pero no el propósito. En sus dibujos, las manos expresan, más allá de su condición figurativa, la búsqueda del espacio cóncavo que los dedos encierran. El espacio que encuentra en la palma de la mano es equivalente al que construye con dedos gigantes de madera u hormigón. Chillida observa sus obras con una mirada cuya idea de escala se distancia del concepto de dimensión. Adquieren así una posibilidad de crecer que facilita imaginar sus espacios como arquitectura. Tras el hierro, el trabajo en madera y alabastro aproxima -en el aspecto formal- la obra de Chillida a la arquitectura. Los títulos de numerosas obras hacen referencia a ella o a conceptos con ella relacionados. Elogio de la arquitectura, Homenaje a la arquitectura, Arquitectura heterodoxa, Modulación del espacio, construcción heterodoxa, Alrededor del vacío, Mesa del arquitecto o Casa de luz, son algunos de ellos. La introducción del vacío en el alabastro da comienzo a un proceso tendente a que el espacio interior tenga una importancia inversamente proporcional a su presencia en la forma exterior. Un proceso de progresivo hermetismo donde pequeños espacios interiores son expresados mediante grandes masas envolventes. El espacio interior es el principal motivo por el que vemos la obra de Eduardo Chillida como arquitectura. La condición de interior, apreciable igualmente en sus grandes obras en el espacio público, hace que estas no constituyan únicamente hitos visuales sino espacios de protección con los que cuerpo interactúa estableciendo una nueva relación con el paisaje, el horizonte o el cosmos. La búsqueda de un interior vacío tiene como consecuencia la evolución hacia la desaparición de la forma exterior. Tal evolución comienza con el diálogo entre el bolo natural de alabastro y el vacío tallado de Homenaje a Goethe, y, como muestra de la inter-escalabilidad de la obra de Chillida, concluye con la introducción de un vacío oculto en la montaña sagrada de Tindaya. El gran vacío de Tindaya nos hace mirar la obra de pequeño formato a través de su filtro de aumento. Nos permite entender que el límite entre arquitectura y escultura es difuso en la obra del escultor vasco. Que la arquitectura puede estar en el origen de su escultura. Que su escultura puede ser el germen de muchas arquitecturas. ABSTRACT It is well known that after leaving his architectural studies Chillida went to Paris in order to begin his career as a sculptor. Back again to the Basque Country, iron is the material in which he finds his own way. In terms of form, his work from the very first ten years is far away from architecture. However, the strength lines set by the iron show a spatial will that is clearly evident in a 1953 piece called Advice to space I. From there on, his work focuses on void. Different materials will set different forms but the purpose will remain the same. In his drawings, hands are expressing, beyond its figurative condition, the search of the concave space that fingers are enclosing. The space founded in the palm of the hand is equivalent to the one built with giant wood or concrete fingers. Chillida faces his work with a look where the idea of scale takes distance to the concept of dimension. His works gets then a possibility to grow that allow us to imagine his spaces as architecture. Following iron, wood and alabaster pieces, in the formal aspect, approaches Chillida´s work to architecture. The titles of many sculptures are referred to it or to the concept related to it. In praise of architecture, Homage to architecture, Heterodox architecture, Modulation of space, Heterodox construction, Around the void, Architect’s table, or House of light, are some of them. The introduction of void in alabaster begins a process leading to the interior space has a presence inversely proportional to its importance in the external form. A process of progressive secrecy where small interior spaces are expressed through large enveloping masses. The interior space is the main reason why we see the work of Eduardo Chillida as architecture. The condition of inner space, equally noticeable in his great works in public space, makes this not only constitute visual landmarks, but protection spaces that body interacts with establishing a new relationship with the landscape, the horizon or the cosmos. The search of an inner void leads to an evolution towards the disappearance of the external form. The evolution begins in the dialogue between the natural bolus of alabaster and the carved void of Homage to Goethe, and as a sign of inter-scalability of the work of Chillida, it concludes with the introduction of a hidden void in the sacred mountain of Tindaya. The great void of Tindaya makes us look at a small format work trough the filter of his increase filter. It allows us to understand that the boundary between architecture and sculpture is diffuse in the work of the Basque sculptor. That architecture can be at the origin of his sculpture. That his sculpture may be the seed of many architectures.
