“We will provide functional and up-to-date technical solutions for this building. The energy supply for the 2.15 megawatt heating system is provided by a district heat transfer station, while the cooling output of 2.15 megawatts is produced by means of chillers.

The façade will be extensively planted with hedges. We are responsible for the central water treatment including pressure increase for the irrigation of the plants and the cleaning of the façade,” says Ralf Thierling, Head of Large Projects at Caverion Germany.

The total area of the new building will be approximately 41,000 square metres plus an additional 23,000 square metres from a basement with parking facilities. Caverion’s delivery will be completed by autumn 2020.
