OKAGEL: High Insulating Day Lighting Systems

Abstract

Today Insulating Glass used in architectural applications has become a dominant part of the building skin. With the increasing number of glass used in buildings, its technical properties become more and more important. For that reason, the insulating glass plays a major role for the buildings energy consumption. Beside the thermal insulation, the solar heat gain and the light transmission are significant parameters. These parameters have to be designed carefully to achieve an optimal performance. Often even contradictory functions, i.e. solar protection and use of natural daylight have to be realized at the same time. A new alternative to standard insulating glass and opaque walls is the use of translucent insulating materials. Therewith, an improved thermal insulation is possible and the solar radiation can be controlled efficiently.
