Climate Campus Lichtenau: Ice Storage Heat Pump
The town of Lichtenau near Paderborn has set itself the goal of actively and passively contributing to lower emissions with an ice-storage heat pump solution. In this way, it wants to emit 250 tonnes less CO2 per year. The installation of a large-scale ice storage tank in October 2021 has brought this goal a big step closer. We took over the planning of the heating and cooling system including control for the project.

Tauris feasibility study – zero-emissions quarter
BAFA-eligible feasibility study for connecting a leisure pool to a new cold local heating network. The redevelopment plan with joint use of existing (CHP) as well as renewable energy sources on the site (geothermal system, existing wells, solar usable areas) promises an improved overall economy while minimizing the CO2 footprint.

Bionic Living 4.0 - Smart Green Building
Bionic Living 4.0 stands for a 100% regenerative coverage for electricity, heat and domestic hot water incl. pool in a fully networked Smart Home. The regenerative energy system is fed by the sun (power generation and heat generation for heating, hot water and the pool), geothermal energy as an additional heat source and rain for the water supply and the pool. The PVT system increases the PV efficiency by 75% and generates heat at the same time.

Energy sheet pile wall with bio heat transfer fluid
A highly modern residential building, coupled with commercial use, is thermally supplied via an energy sheet pile wall (insertion depth: 5m) installed in the surrounding garden. The energy source has year-round groundwater contact, provides highly efficient heat pump operation and supplies cold for cooling in summer. The energy sheet pile wall is operated with a 100% biodegradable heat transfer medium that does not contain glycol and is also excellently suited for water protection areas.

Belgrade Hilton, heat pump network
The Hilton Hotel is the first large-scale project in Belgrade to take on a pioneering role, as the heating and cooling management is provided exclusively without fossil fuels. With a drilling depth limit of 120 m, it was possible to place 70 coaxial geothermal probes under the hotel complex on an area of 17,500 sqm. The supply for heating (1 MW) and cooling (750 kW) is thus emission-free in the middle of Belgrade's city centre.

London Institute of Physics, refurbishment
The London Institute of Physics is setting an example for climate protection with an energy refurbishment of the institute's building: In central London, near King's Cross station, the heating and cooling requirements (195 kW) are now covered with high-performance geothermal storage probes, a challenge given the energy demand in relation to the small inner-city building footprint.

Troisdorf: Climate protection settlement, local heating network
The development and realisation of the local heating network on a geothermal basis was carried out with financial support from the Energy Agency of the State of NRW. The probe field placed under the building generates energy for a heating and cooling demand of 190 kW. The project received the "Climate Protection Settlement" award due to the innovative geothermal local heating concept.

Lübeck: Housing block refurbishment
The energetic refurbishment of the apartment block from the 1960s was carried out primarily with regard to the urgently required replacement of the oil heating system, which emits considerable amounts of CO2, with a heat pump system. With a drilling depth limit of 39 metres, geothermal energy can only be extracted via volume coaxial probes (112 kW).

Urmond: Renovation of a retirement home
In this Dutch retirement home with a heating and cooling requirement of 550 kW, the energy supply could be ensured exclusively with geothermal energy via a local heating network. With a drilling depth of 80 metres, volume storage probes provide the required output for comfortable air conditioning.
