Facades are subjected to numerous structural and technical challenges, while at the same time they are required to offer maximum visual and thermal comfort. For that reason, their planning and execution demand the utmost care and attention. Highly efficient types of glass make it possible to lower operating and energy costs, while at the same time making it possible to significantly enhance the optical quality of a building for both the user and observer.

Energy-efficient architecture does not have to have a certain image. This is clear in the work of Sauerbruch & Hutton, which has a sober but colourful image.
