Building: BIG - Bjarke Ingels Group HQ
Location: Nordhavn, Copenhagen, Denmark
Floor area: 4700 m2
Year of commissioning: 2022
Energy system delivery: 132 MWh/year heating (84% of the building’s heating demand), 60 MWh/year cooling (100% of the building’s cooling demand)
At BIG – Bjarke Ingels Group’s new headquarters in Nordhavn, Copenhagen, heating and cooling needs are efficiently met through an integrated geothermal energy solution provided by Energy Machines ApS. The new building, in construction, is set to open in the autumn of 2023.
Here, thermal energy is stored within energy piles produced by Centrum Pæle A/S. Energy piles are specially manufactured concrete foundation piles equipped with energy storage capabilities. BIG HQ is standing on 222 energy piles, each measuring 14m in depth.
These piles serve as the building's primary heat source during winter and cooling medium during summer. This is achieved by increasing or decreasing the ground temperature through the operation of an Energy Machines heat pump. Any surplus heat is stored in the piles for later use.
Our flexible control platform, Energy Machines Control, ensures seamless operation, continuous monitoring, and optimization of the system through the convenience of the cloud.
Thanks to this integrated approach, the geothermal system successfully fulfills 84% of the building's heating demand and 100% of its cooling requirements. In cases of peak load during the coldest periods, the remaining heat demand is met through the use of district heating.
