Geothermal energy

We advise on and plan geothermal systems. Our range extends from near-surface installations such as horizontal ground collectors to deep geothermal systems. From the initial assessment of potential through to implementation, we support your project. Our clients include private individuals with single-family homes as well as cities, municipalities and industry.

Our planning is based, among other things, on the HOAI (German fee schedule for architects and engineers) and the AHO guidelines.
