Fixed sunshade device for overhead glazing

Abstract

ABSTRACTGist of the lecture is a fixed solar protection system for overhead glazing consisting of intersecting lamellae that form a grid structure. The structure is optimized to the geographical location and the installation situation. The maintenance‐free system provides efficient sun protection combined with glare‐free daylighting and free view outwards. After a short introduction to the problem and a small insight into the history, the efficient operation of the sun protection grid is explained. The various applications in the macro, midi, micro and nano‐range are shown. The micro region is most extensively explored at this time. This involves the use of optimized grid structure in the pane interspace (SZR) of insulating glass. The form‐finding and the necessary parameters are explained. A selection of different grid structures is researched. Experimental measurements on prototypes include radiation‐physical characteristics as well as the g‐value measurements in a calorimeter. The results of these studies will be analyzed and transferred to simplified calculation methods. The analysis provides a broad image of the operation of the different geometries and the potential of this sun protection system. The work shows that the fixed sunscreen grid system represents a sustainable solution in the field of glass roofs. The presented system is trademark protected in Germany and patent pending. The author seeks to develop the solar shading system further to market.
