New infrastructure, hidden behind an artificial stone How Triemlifussweg should have looked The areas along the hills, where there is no groundwater, are potentially suitable for geothermal use. Diagram of the heat logistics, showing the interplay of solar energy and geothermal energy - One of the basic ideas of the LowEx concept developed by Prof. em. H. Leibundgut is to transfer heat from the summer into the winter. Section through the geothermal network along Triemlifussweg - drilling is only conducted in areas with no trees Map of all the trees and the underground parking garages (pink) along Triemlifussweg The drilling reaches a maximum depth of 272m below ground. A geothermal network allows a contemporary heating and cooling system for all the post-war buildings along Triemlifussweg The drilling is conducted in clearings along the Triemlifussweg, the difference between forested and grass areas is strengthened.
