Central Administration of the EVS
The existing central administration building of the EVS (EnBW) was erected in the 1970s and is covered with dark siding made of anodized aluminum and Calorex glass. In order for the new building to harmonize, a dark grey brick with a slight metallic shimmer was chosen for the outer shell. The level joints use white mortar while the vertical joints use black mortar, and in analogy to the ribbon-like windows, they help emphasize the horizontal character of the new structure. The entire building, except for the necessary window-openings, is encased in a double-shell masonry and steel-cement façade. This encasing, in combination with the specially developed box-windows, enables a high level of warmth-retention. A further advantage is the building´s high thermal inertia. This is caused by the fact that the heavy exterior walls, the majority of the interior walls and the vault in the ceiling of the dining hall are built of brick (text from website architects).
