Analysis of house prices to assess economic impacts of new public transport infrastructure: Madrid metro line 12.

Transportation infrastructure is known to affect the value of real estate property by virtue of changes in accessibility. The impact of transportation facilities is highly localized as well, and it is possible that spillover effects result from the capitalization of accessibility. The objective of this study was to review the theoretical background related to spatial hedonic models and the opportunities that they provided to evaluate the effect of new transportation infrastructure. An empirical case study is presented: the Madrid Metro Line 12, known as Metrosur, in the region of Madrid, Spain. The effect of proximity to metro stations on housing prices was evaluated. The analysis took into account a host of variables, including structure, location, and neighborhood and made use of three modeling approaches: linear regression estimation with ordinary least squares, spatial error, and spatial lag. The results indicated that better accessibility to Metrosur stations had a positive impact on real estate values and that the effect was marked in cases in which a house was for sale. The results also showed the presence of submarkets, which were well defined by geographic boundaries, and transport fares, which implied that the economic benefits differed across municipalities.

The Islamic Crossed-Arch Domes in Cordoba: Geometry and Structural Analysis of the “Capilla de Villaviciosa”

Crossed-arch domes are a singular type of ribbed vaults. Their characteristic feature is that the ribs that form the vault are intertwined, forming polygons or stars, leaving an empty space in the centre. The earliest known vaults of this type are found in the Great Mosque of Córdoba, built ca. 960 a.C. The type spread through Spain, and the north of Africa in the 10th to the 16th Centuries, and was used by Guarini and Vittone in the 17th and 18th Centuries in Italy. However, it was used only in a few buildings. Though the literature about the structural behaviour of ribbed Gothic vaults is extensive, so far no structural analysis of crossed arch domes has been made. The purpose of this work is, first to show the way to attack such an analysis within the frame of Modern Limit Analysis of Masonry Structures (Heyman 1995), and then to apply the approach to study the stability of the dome of the Capilla de Villaviciosa. The work may give some clues to art and architectural historians to understand better the origin and development of Islamic dome architecture.

Heterogeneous Collaborative Sensor Network for Electrical Management of an Automated House with PV Energy

In this paper we present a heterogeneous collaborative sensor network for electrical management in the residential sector. Improving demand-side management is very important in distributed energy generation applications. Sensing and control are the foundations of the “Smart Grid” which is the future of large-scale energy management. The system presented in this paper has been developed on a self-sufficient solar house called “MagicBox” equipped with grid connection, PV generation, lead-acid batteries, controllable appliances and smart metering. Therefore, there is a large number of energy variables to be monitored that allow us to precisely manage the energy performance of the house by means of collaborative sensors. The experimental results, performed on a real house, demonstrate the feasibility of the proposed collaborative system to reduce the consumption of electrical power and to increase energy efficiency.

VLC-based light-weight portable user interface for in-house applications.

Advances in solid-state lighting have overcome common limitations on optical wireless such as power needs due to light dispersion. It's been recently proposed the modification of lamp's drivers to take advantages of its switching behaviour to include data links maintaining the illumination control they provide. In this paper, a remote access application using visible light communications is presented that provides wireless access to a remote computer using a touchscreen as user interface

Casa Cúpula en Carbondale, Illinois. R. B. Fuller, 1960 = Domo House in Carbondale, Illinois. R.B. Fuller, 1960

Si existe una imagen verdaderamente elocuente para describir a Richard Buckminster Fuller (1895-1983) esta es, sin duda, la que el pintor Boris Artzybasheff (1899-1965) realizó para la portada con la que la revista Time abrió el 10 de enero de 1964. En ella se puede ver como la cabeza de este inventor, ingeniero, poeta y arquitecto se encuentra facetada en cientos de triángulos, formando algo que no es sino una cúpula geodésica, como aquellas que le habían hecho famoso en todo el mundo. Frente a esta identificación que se da en la imagen de Artzybasheff entre Fuller y sus cúpulas, transformando al arquitecto en su propia obra, lo que se pretende realizar en este trabajo de investigación es el camino inverso, penetrar en esa cabeza o, mejor dicho, en esa cúpula que la alberga, a través del estudio de una de las cúpulas más personales que construyera RBF: la que fue su casa en Carbondale, en la que vivió durante toda la década de los años sesenta del pasado siglo, precisamente los mismo años de aquella fantástica portada de Time. El análisis detallado de esta obra nos permitirá acercarnos al centro gravitacional del pensamiento de RBF: la búsqueda de una mayor libertad para el hombre gracias a una arquitectura más sostenible y, por ello, más económica. Una búsqueda que le llevó a crear no sólo una casa, sino todo un mundo propio.

Utzon and the sun path as an organizing element of life in a house

The present text intends to analyze the hypothesis stating that the path of the sun can be an organizing element for how you live in the houses designed by Jørn Utzon. To do so, I have selected twenty houses and building complexes designed by him between the years 1950-94, in Denmark, Sweden, The United Kingdom and Spain. In these projects I will look for elements which are repeated and their possible meaning. The aim is to reach practical conclusions that could help us decide how to orientate a house.

Hacia la nueva sociedad comunista: la casa de transición del Narkomfin, epílogo de una investigación = Towards the new communist society: the transition House of Narkomfin, a research epilogue

En el contexto de inestabilidad y cambio vivido en la URSS durante la década de 1920, un grupo de arquitectos dirigido por Moisei Ginzburg abordó el tema del alojamiento de masas. Su misión no sería sólo dar solución al problema de la vivienda, sino redefinirla como el marco adecuado para una sociedad sometida a un cambio sin precedentes. La respuesta se desarrolló a través de un proceso de investigación que duró más de cinco años, en tres aproximaciones sucesivas que culminaron con el edificio Narkomfin. La primera, de carácter conceptual, se formalizó en el Concurso Amistoso de 1926. La segunda se articuló a través de la investigación del Stroikom bajo premisas científicas y metodológicas. Finalmente, las conclusiones tipológicas alcanzadas en esta segunda etapa se materializaron en la construcción de algunos ejemplos, entre los que destacó el edificio Narkomfin. Este último acercamiento, de carácter empírico, ha sido tradicionalmente examinado por los expertos como un hecho aislado. Sin embargo, su estudio debe trascender necesariamente el genio del autor-creador en favor del proceso de investigación al que pertenece. Sólo desde este punto de vista cobra sentido la consideración de Ginzburg sobre su propio edificio como un medio propositivo y no impositivo: un proyecto concebido como una herramienta de transición hacia una sociedad más avanzada.
