Data centre heats offices
The extension of Züblin's central office meets high structural and energy efficiency standards. The construction group was awarded the certificate in Gold by the German Sustainable Building Council (DGNB) for the extension. The BINE Projektinfo 6/2017 "Servers heat office buildings" presents the energy concept along with monitoring results for the new five-storey building.
Lighting plays crucial role in the energy balance
The office building has low heat requirements, which are almost entirely covered by waste heat from the data centre. When this supply does not suffice, a combined heat and power plant in the neighbouring building provides the required thermal energy. With an average U-value of 0.4 W/m2K, the building envelope of the reinforced concrete structure reaches the level of a passive house. The exterior walls consist of prefabricated timber frame elements, which were transported to the construction site with pre-installed windows, solar shading and a sheet metal covering, and were installed there.
