A new method for light shelf design according to latitudes: CUN-OKAY light shelf curves

Journal of Building Engineering, 2017
Abstract The effect of location on earth to the light shelf position & size and the correlation between latitudes with light shelf dimensions is explored on a sample office unit for different heights in this manuscript. For this purpose, a typical office unit is modelled with Ecotect software and variety size/position of light shelves are tested to ...

Light shelf performance in Madrid, Spain

Building and Environment, 1997
Abstract 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 ...
