With the involvement of various specialists, the planners
developed a concept with which both demands could be fulfilled
at the same time:
a combined shading and photovoltaic system. The ten rows of
skylights in the building, each 12 meters long on average, were
equipped on the outside a motor-powered, adjustable blanking
system alternating with fixed, partially transparent
This configuration led to optically appealing chessboard
pattern for the entire skylight area.
All CIS shading elements include ventilation. This avoids
permeation of the radiant heat energy into the building.
As part of a coordinated energy concept, adjustable glass
plates were installed on the facade to complement the skylight
solution. The overall strategy applied made it possible to
regulate the lighting and incident radiation conditions within
the atrium, to effectively block the penetration of incident
sunlight and, at the same time, to generate power.
