Colourful glass louvers on office in Colonia, S&H

To reduce the input of heat produced by direct solar radiation, computer controlled exterior shutters adapt to each moment of the day. Besides, these vertical elements integrate flat glasses in the curved shape of the building.
The vertical pivoting shutters can also be regulated with the control panels installed in offices.They have a serigraph pattern that allows exterior views without going against solar and privacy protection. The serigraph blurs from a dense proportion on the bottom to a lighter on the top.
