Heat pump-based grids for demand-responsive heating and cooling supply.

Heidelberg: Heat from waste water

The city of Heidelberg has tightened its climate targets and wants to become climate-neutral by 2030. To this end, the municipal utilities commissioned feasibility studies for many energy areas such as biomass and geothermal probes or grid hydraulics, the results of which are being incorporated into a transformation plan. goodmen energy prepared a feasibility study on the district heating potential of wastewater from the sewage treatment plant in conjunction with a high-capacity heat pump. 


Stuttgart: Thermal water as WP source for DAS LEUZE

Since the city of Stuttgart wants to become climate-neutral by 2035, all swimming pools must also reorganise their energy supply to be as CO2-neutral as possible. That's why we have now taken on DAS LEUZE am Neckar. We developed an energy concept for the year-round thermal baths with outdoor area and pool, which uses the 20° C warm Leuze spring water as an energy supplier for several heat pumps.


Baden-Württemberg: Climate-neutral production location

In Vaihingen an der Enz near Pforzheim, an industrial company wants to make its production climate-neutral in the future. goodmen energy has developed a regenerative energy concept that takes a holistic view of heating, cooling and the electricity required for this and serves as a model for other locations.


Stuttgart: New heating concept for the outdoor pool

The city of Stuttgart wants to become climate-neutral by 2035. Therefore, the Inselbad in Untertürkheim is to be the first open-air swimming pool in Stuttgart to be supplied in a CO2-neutral manner. In our feasibility study, we analysed and compared various concepts and calculated their economic viability.


Hamburg: Hybrid geothermal probe/air heat supply

goodmen energy planned a regenerative energy supply system for the new headquarters of a medical technology company with a total gross floor area (GFA) of around 10,0000 sqm. The technical planning in phases 1-5 has already been carried out.


North Rhine-Westphalia: Holiday settlement at the quarry pond

A large holiday park is planned on the border to the Netherlands in North Rhine-Westphalia. The client asked for a sustainable energy concept in which the thermal and electrical supply would be provided by renewable energies. goodmen energy developed a supply concept for heat and electricity from renewable energies in a feasibility study, which also included the lake.


Munich: Redevelopment of WEG real estate

For WEGs, we develop individual, location-oriented and financially suitable concepts to reduce operating costs and increase property value. These measures are highly eligible for subsidies, so that WEGs and thus each individual owner can save a lot of money with the right advice.


Feasibility study SN: Decarbonising industry

goodmen energy prepared a feasibility study for an industrial production site and developed an efficient and sustainable energy concept for the existing production and for a planned new building. The measures developed could considerably reduce electricity consumption.


HP-PVT 4.0: combining heat pump and PVT efficiently

goodmen energy participates in several research projects to drive innovation in the field of renewable energy. We are currently part of the HP-PVT 4.0 research project under the auspices of Fraunhofer ISE and with funding from the Federal Ministry of Economics and Climate Protection (BMWK).


Renovate building portfolio, reduce CO2 emissions

The retirement home is no longer up to date in terms of efficiency. Prior to the refurbishment, the property owner commissioned goodmen energy to analyse and calculate the potential savings through an energy refurbishment. It was also necessary to identify funding opportunities. In this way, primary, final and useful energy requirements as well as CO2 emissions can be significantly reduced.



Feasibility Study DUS: Digital Twin Simulation

In order to be able to plan the supply of a new building from renewable energy sources, goodmen energy simulated a Digital Twin based on the building specification. The resulting energy concept makes the office building a role model for energy efficiency and environmental friendliness.


Havelquartier Potsdam - Aquathermy on the river banks

A new district is currently being built on the banks of the Havel River in Potsdam, called Havelquartier Potsdam (HQP). The six building complexes are located within walking distance of the city center. To heat and cool one block of buildings, a thermally activated sheet pile wall was installed along the shore. goodmen energy received a subcontract from ZAI GmbH Ziegler-Aulbach to design the technical subsoil equipment (TBA) with a focus on hydraulics and heat pump integration.


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.


Munich: 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.

Grevenbroich: Vonovia, refurbishment

Vonovia SE, Europe's leading private housing company with around 415,000 flats, is building on a geothermal concept for the refurbishment and extension of apartment buildings in Grevenbroich.
