The 16-metre-high glass atrium of the Lapp Group's headquarters
At the new European headquarters of the Lapp Group (U.I. Lapp GmbH) in Stuttgart-Vaihingen, the open-space concept is lived right into the detail. The transparent exterior of the administration building is characterized by large window areas; the two L-shaped wings of the building are connected by a 16-metre-high glass atrium. In order to maintain the openness, Lapp decided to use the dimmable glass EControl smart 45/8 (EControl, Plauen). It offers two advantages: an unobstructed view to the outside remains guaranteed – and the intelligent glass has a positive effect on the air conditioning of the atrium.
The main challenge was to realize both the desire for transparency and protection from heat and glare in a "visible" way. Detailed product research finally led the planners from Schwarz Architects to the perfect solution – dimmable glass from the company EControl in Plauen.
In the atrium, with its 16-metre-high glass façade, 85 m² of EControl smart 45/8 provides shading within the glass, an unobstructed view in the best weather and a pleasant climate in the foyer. With their electrochromic properties, the glass panes combat overheating of the atrium whilst maintaining transparency. The solar factor (total energy transmittance) of the dimmable triple-pane insulation glass EControl 45/8 at the strongest dimming level is only 8% – which also reduces the requirement for air conditioning. Because the panes can be regulated in steps, the shading always matches the current weath...
