Mounting of Façade
Façade redevelopment for increased energy efficiency

The entire protected façade will be replaced without changing its visual appearance. The existing 2-paned insulating-glass façade will be replaced with a state-of-the-art box window façade. The fixed-glazed exterior panes (1 glass layer) will be given small air vents that enable an exchange of air with the outside by opening the inner 3-pane window casements. This allows for natural ventilation to the outside.
Finally the animation shows the circulating air, first when the inside window is closed – the air is channelled to the outside again – and then when the inside window is tilted – fresh air circulates into the office.
