The building is conceptually designed for maximum efficiency. This also ensures faster internal construction. “With us, the entire building technology, heating, cooling and ventilation, for example, is installed in the ceilings of the building. This delays something in the shell construction, but after all it is already finished,” he continues. This design has great advantages, especially in operation. “Since all pipes and hoses are firmly integrated into the concrete ceiling, they are optimally protected. Subsequent maintenance is minimal. The system is almost maintenance-free for 50 to 100 years,” he points out. This has particular advantages for heating and cooling. The pipes used for this are also located in the middle of the floor slabs. “With normal underfloor heating, this is laid in the screed. The heat mainly comes from below and is distributed by air circulation. With us, it is the entire concrete core of the building that is heated or cooled in the summer. So it is much more heat radiation comfortable,” he says. Added to this is the extreme efficiency.
