In a line of investigation titled “Optimization of natural lighting”, we have developed a device designed to improve lighting and heating conditions in a room. The Fragmented Light Shelf (FLS) is a shading device that can easily be incorporated into the window. This is a continuation of work that has emerged from software simulation and monitoring...
The study arises from the software simulation and monitoring in 1:10 scale model of some sun protection options a light shelf. The results show that the system prove to work as sun protection, while improving natural lighting at certain times of day. However, it is necessary to optimize the performance and extend the scope to other Spanish cities w...
The overall objective of this work is to provide diffuse illuminance availability at Madrid (Spain) through a statistical analysis of illuminance values corresponding to a long-term data series. The illuminance values are obtained from irradiance measurements by means of different empirical models for luminous efficacy. The values of diffuse illumi...
The Fragmented Light Shelf (FLS) is an element that improves the natural lighting, provides solar protection and can be easily incorporated into the window of a building under refurbishment, or a new construction. This element is made of two components the shelf and the louvers. These two components can vary, either by the construction material or...
When measured daylighting data are not available, but solar radiation is recorded, if values of the luminous efficacy are known, daylighting data can be estimated. In this paper we give the results of measurements of the luminous efficacy of global solar radiation, obtained in Madrid, in April, May and June, 1989, which are the first published for...
The objective of this paper is to present the computer simulation results that we have obtained with a new window design. This prototype is equipped with the elements necessary to capture and distribute natural daylight in an optimum way. The whole window system is able to be adapted to the weather conditions of most of the Iberian Peninsula. Its d...

La presente investigación, forma parte del proyecto INVISO (Industrialización de la vivienda sostenible),
en el subproyecto 10, (Sistemas para la optimización del comportamiento eficiente de las viviendas), que
se está desarrollando en la Escuela Técnica Superior de Arquitectura de Madrid. El subproyecto está
dirigido por el Grupo de Investigación...
Te aim of this paper is the design and construction of a window which will contain all the elements to capture and distribute natural daylight in an optimum way, while protecting from an excess of solar light and reducing the heat loss. A small scale model is being constructed which is adjusted to what the construction industry in Spain establishes...
Parte de la investigación desarrollada en el subproyecto 10, SISTEMAS PARA LA OPTIMIZACIÓN DEL COMPORTAMIENTO EFICIENTE DE LAS VIVIENDAS. En relación con los huecos de fachada, están aquellas que integran estrategias de iluminación, climatización y sombreamiento.
A simple graphical method proposed by the CIE (Commission Internationale de l'Eclairage) to estimate the daylight factor for overcast skies, at an early stage of daylighting design, at a reference point located at 60 cm from the rear wall along the centre line of a room having a window in the front wall, has been tested at Madrid, Spain, using a sc...
The performance of a light shelf with a reflectance of about 91% after excluding the specular component (reflectance about 1%), providing for solar protection during the long, hot, dry summer season, is studied in Madrid (40.4°N, 4.4°W) using two scale models (1:10) with rectangular openings facing south, one taken as a reference and the other equi...
The performance of a light shelf, with a reflectance of about 91% after excluding the specular component (reflectance about 1%), providing for solar protection during the long, hot, dry summer season, is studied at Madrid (40.4° N, 4.4° W) using two scale models (1:10) with rectangular openings facing south, one taken as a reference and the other e...
Different shading devices allowing for the same degree of solar protection and providing a wide scatter reflection, are installed in scale models and tested in relation to their potential use as daylighting systems, during two months of the characteristic Spanish hot summer season. Performance relating illuminance levels and illuminance uniformity...
A number of relations are available to estimate monthly mean diffuse solar radiation on an horizontal surface (D) when the monthly mean daily global radiation (G) and/or the monthly mean daily number of sunshine hours (S) are known. In the present work, taking as a reference 264 values of D computed for the period 1966-1975 with the European Commun...
