Geothermal Activation of underground structural walls
Scientific Planning Support with geothermal Simulations
The project consists of 6 buildings with different uses. Under the basement floor slab there are underground structural walls of up to 30 m depth.
Our teams’ focus was to analyse the potential of the use of geothermal energy through this underground structure.
To quantify the geothermal energy use, the specific in- and outgoing powers through the walls were calculated using a dynamic simulation of the ground based on measurements and underground water temperatures. Based on this, the energy inputs and outputs could be calculated and were the basis for further energy system planning.
Realisation 2022/2025, site area: 15.000 m², total floor area: 105.000 m²
