The new Energie AG group headquarters in Linz

GIG LEDS is the first passive house facade to be suitable for high-rise buildings. LEDS is an acronym for Low Energy Double Skin and the related system, which has been developed and patented exclusively by GIG, consists of a passive house standard element facade with AHC (Active Humidity Control). Particularly outstanding is the overall U-value of 0.60W/m²K and the 638 m² photovoltaic area.  

In addition to its overall architectural design, the new Energie AG group headquarters has aroused great interest due to its use of the world’s first passive house facade for a high-rise building as this makes heating in the offices unnecessary. Sun protection is provided between the glass panes by a light deflection effect and this new type of lamella system, ensures that light illuminates the entire room. At the same time, overheating caused by the sun is prevented without obstructing the view from the window.
