The École Polytechnique Fédérale de Lausanne (EPFL) has built a highly innovative building on campus – the Discovery Learning Laboratory (DLL).

This building offers modular workplaces dedicated to practical work in electricity, electronics, optics, robotics and communication for EPFL Bachelor students.
For this project, GEOEG performed the energy design and construction survey of an energy foundation comprising micropiles, walls, and slabs equipped with pipe heat exchangers to harvest renewable shallow geothermal energy. This design has provided a solution that will meet 100% of the thermal energy requirements of the DLL in combination with the local district heating network.
