Renewable energy

The intelligent combination of different renewable energy sources is the key to a future-proof, climate-neutral heat and cold supply. We design and plan energy systems consisting of district heating and anergy networks (5GDHC), solar thermal, photovoltaic-thermal (PVT) and large heat pumps, together with geothermal energy and underground storage.

Our clients include municipal utilities, district developers, industry and municipalities.
