VIP envelope

Vakuum-Insulation-Panel (VIP)

Construction detail

A major share of the total reduction of 90 % in the heating demand is due to the new envelope, where its extreme slenderness and efficiency allowed us to master all technical and optical construction and connection problems. Despite this, by avoiding other changes in the construction we succeeded in keeping the costs close to those of a standard solution. In addition, a ventilation system with a heat-recovery unit was installed.
