An efficient energy system results from the perfect configuration of its components. That's why we rely on sophisticated and intelligent combinable green technologies.

Energy sources

Smart Green Technologies for regenerative energy harvesting enables the best possible use of existing, natural sources, precisely where the maximum potential is possible. We solely use the CO2-neutral primary sources wind, water, and solar energy, geothermal energy, air, and exhaust air as well as environmental energy.

Near-surface geothermal energy

Geothermal collectors

Proven technology from the very beginning - even better solar regenerated by PV thermal collectors..

Ring trench collectors

High cost efficiency for small buildings - simple planning, quick installation.

Vertical collectors

High area efficiency at a depth of only 1.5 meters - from single-family houses to quarters.

Drainage + collectors

Systematic anergy use of stormwater and snowmelt for very large buildings and quarters. 

Geothermal baskets

Eco-friendly and maintenance-free use - even in water protection areas.

Spiral probes

High installation flexibility - vertical or horizontal between 1.5 m to 5.0 m depth.

Ramming probes

Innovation: Highest flexibility concerning the installation position without time-consuming earthworks. 

Storage probes

Innovation award winner: probe and storage tank integrated - ideal for drilling depth limitations.

Geothermal probes

Proven technology up to 400 m depth - but the details make the difference.

Energy piles

The proven technology in special civil engineering. The implementation skills make the difference.

Aquathermal energy

Energy sheet piling

Unbeatably efficient on flowing water. We also plan retrofittable technologies. 

Water heat exchanger

The smallest volume performance package for waters bodies, cisterns, and  water storage tanks.

Groundwater heat exchanger

Proven technology with high efficiency - it all depends on the water chemistry and well construction!

Wastewater heat exchanger

Heat recovery from wastewater and sewage treatment plants. Here too, the dual-use is captivating.

Environmental and solar energy

Photovoltaics (PV)

The most powerful modules for self-powered heat pumps and the realization of your e-mobility.

Photovoltaic-Thermy (PVT)

Power-heat collectors with the highest system efficiency - heating, cooling, electricity generation, and regeneration of geothermal sources.

Solar-Thermy

The most powerful modules for bivalent systems.

Outside air

Proven technology for single-family homes - even more efficient as a hybrid system.

Heat recovery and Carbon Capture

Recirculated air

Heat recovery from internal heat sources. Extremely reasonable due to dual-use.

Exhaust air

Heat recovery from free industrial process energy. Synergy that cannot be ignored.

Carbon Capture

Energy from sewage sludge and biomass with simultaneous CO2-binding, e.g. by means of pyrolysis.

Waste water heat exchanger

Heat recovery from waste water and sewage treatment plants. Here, too, the dual use is impressive.

Storage of energy sources

Ice storage

Latent heat is properly planned for small and large construction projects.

PCM storage

Latent heat in the desired temperature range. Highest precision through defined liquid properties (Phase Changing Material) - flexible and mobile.

Hydrogen storage

Economical production, low-pressure storage, and use of hydrogen for neighborhoods and large buildings.

Aqua-Farming

Smart 'energy swings': (sector) coupling of scalable urban farming systems (fish farming, aquaponics) to buildings and neighbourhoods.

Pools

The coupling of swimming pools as energy sinks in holistic energy concepts is becoming increasingly important as a solution approach.

Solar, wind, and hydropower for electricity generation

Photovoltaics (PV)

The most powerful modules for self-powered heat pumps and the realization of your e-mobility.

Small hydroelectric power plant

Highest innovative power through ecological compatibility. For small and large locations.

Small wind turbine

Vertical wind turbines as a synergetic system extension to photovoltaics.

Decentralized heat pumps & centralized large heat pumps

For the implementation of an optimal regenerative energy supply, all proven heat pump systems are used. Here, too, we pursue the goal of planning energy-efficient machines that are integrated into the energy system using the latest control technology.

We are planning the following compression heat pumps:

  • Air-water heat pumps
  • Brine-water heat pumps
  • Water-water heat pumps
  • Hybrid heat pumps (e.g. brine-air)

In addition, we also develop bivalent systems to be able to continue to use existing infrastructures sensibly, but at the same time to significantly reduce CO2 pollution.
