local heating supply
by near-surface geothermal energy in existing residential buildings

We convert your unrenovated property almost climate-neutrally during ongoing operation and this with a guaranteed term of 20 years. Depending on the condition of the property and the ground, the efficiency class improves to A or B.

Partner for climate-neutral conversion of your property

For portfolio holders with at least 100 residential units or 16 buildings, DGC offers the climate-neutral conversion of unrenovated housing stock using near-surface geothermal energy

After installing the geothermal local heating network, we act as an energy supplier and thus create independence from fossil fuels and geopolitical changes for you. Our many years of expertise in the real estate industry helps us to shape climate neutrality from the perspective of real estate companies.

"We reconcile the needs of owners and tenants with a sustainable approach to nature"  (Christoph F. Trautsch)

With the option of flat-rate energy supply costs (heating, cooling, hot water), tenants and property owners benefit from total rental costs that can be planned in the long term. The environmental friendliness of the geothermal basic supply significantly increases the attractiveness of the property for tenants and owners.

Our potential study - your roadmap to the climate-neutral conversion of the property

The potential study covers six areas and examines all of the circumstances of your property in detail.

The starting point is the geological analysis of the soil conditions at the site. In addition, the necessary legal framework conditions, possible hazard potentials, as well as the complete pre-dimensioning for the geothermal development are dealt with. In addition to the lighting of the legal framework by our internationally renowned partner law firm, the detailed economic consideration with simulation models plays a central role in the study. These simulations show the economic advantages of the geothermal local heating network and thus represent an essential basis for upcoming investment decisions.

The extensive state subsidy options are put together individually and thus optimally for your property by our specialized cooperation partner as part of subsidy management.

DGC enables reduction of capital commitment

The near-surface geothermal energy – THE ALTERNATIVE to the classic and to a large extent equity-binding energetic renovation. The DGC offers the conversion of the entire property to "climate-neutral operation" for a flat rate in line with the market.

The installation of the DGC local heating network achieves a share of renewable energies of 75% and thus clearly exceeds the legally prescribed minimum share of 65%.

Only through the DGC local heating network, with its high proportion of renewable energies, can the classic renovation measures be significantly reduced and also open up the possibility of benefiting from extensive government support programs.

emission reduction

No emission of harmful greenhouse gases due to the heat supply using near-surface geothermal energy. By using "green electricity" to supply the heat pumps, the building's emissions can be almost completely reduced.

heating cost reduction

Geothermal energy is considered to be the only renewable energy source that enables buildings to be reliably supplied with a base load 365 days a year.

The operating costs of the local heating network can be planned in the short and medium term, which enables the supply costs to be calculated based on legal requirements.

Buildings with radiant heating also allow for passive cooling, resulting in significant savings in initial and running costs

Geothermal energy - the basis for the optimal energy mix

With base load supply from geothermal energy, the energy supply of the property can be further optimized by using other regenerative energy sources (wind, solar, biomass).

Elimination of energetic renovation costs

Buildings with fossil fuels have to be energetically renovated in the classic way, for example with thermal insulation composite systems (ETICS) or new windows, in order to meet the statutory reduction in annual heating requirements.

Since the DGC local heating network does not cause any harmful emissions, there are no investments to reduce the transmission heat loss of the building.

Conversion during ongoing property operations

Although the drilling for the local heating network represents a not insignificant construction measure, this work can be carried out without major restrictions during ongoing operation.

Geothermal local heating supply contract - advantages for owners, tenants and the environment

Contrary to the usual billing based on the amount of heat generated, the DGC heat supply contract offers so-called flat-rate contracts which, on the basis of the legal basis, grant tenants and owners maximum planning security over a period of three years.

chronological sequence

  • Extensive schedule and execution plan in coordination with the owner

  • Installation of the geothermal local heating network takes place smoothly during normal property operation

  • Calculated period of time from commissioning to completion 12 months
