Objective:        Energy resources are shrinking and as a result, energy costs are continually on the rise.  This provides an opportunity for innovative alternative energy sources like the sun.

The easiest way to capture the sun’s energy is through your window.  Through a window you can transport about 70% of the sun’s energy as light and warmth into the room.


The KSD®-Solar-Diode-Window is the only window construction to address
room temperature control and energy saving at the same time in an ingeniously simple way. At the end of the 1980s the principle of the KSD®-Solar- Dioden-Window was invented in Germany and patented.  Since 1992, the University Cologne has followed the development of „Solare Anlagen und Bautechnik“ (Solar Equipment and Building Technology) on a scientific basis and proven the energy efficiency.  The KSD® - SOLAR WINdow combines in its functionality heating, cooling, noise reduction, safety, insulation, versatility and as a result achieves an unrivaled price – performance ratio.
