Imagine wanting to install underground heating and cooling in an old building — maybe even a protected historic one — but the drilling is too expensive, the machines are too big, and nobody knows which setup works best for your soil and climate. This project built smaller drilling machines that fit into tight urban spaces, designed better underground heat exchangers, and created decision-support software that tells you exactly which geothermal setup works for your building type, local geology, and climate zone. They tested these solutions across 3 European climate zones and 10 countries, covering everything from single-family homes to multi-user historic buildings.

The business problem
What needed solving
Retrofitting buildings with geothermal heating and cooling is expensive and complicated — especially in dense urban areas and historic buildings where conventional drilling rigs don't fit, existing heating systems can't be ripped out, and every site has different soil and climate conditions. Building owners and contractors face high drilling costs, oversized equipment, design uncertainty, and the risk of costly mistakes when choosing the wrong geothermal configuration.
The solution
What was built
The project developed compact drilling machines and methods adapted to constrained built environments, improved borehole heat exchangers, modular high-temperature heat pumps that connect to existing heating terminals without replacement, and a decision support system (DSS) with apps that match the optimal geothermal solution to each combination of building type, climate zone, and geological conditions. Across 32 deliverables, this included energy demand modelling for residential, non-residential, and historical buildings at 2 insulation levels in 3 climatic zones.

Business applications
Who can put this to work
Building renovation and energy retrofit
SME
Target: ESCO (Energy Service Company) or building retrofit contractor
If you are an energy service company struggling with the high upfront cost of geothermal installations in urban renovation projects — this project developed compact drilling machines and methods specifically adapted to the built environment, plus a decision support system that matches the right geothermal configuration to each building type across 3 climatic zones. This means faster project scoping, fewer design mistakes, and lower drilling costs for your retrofit contracts.
Heritage and cultural property management
any
Target: Heritage building management company or public building authority
If you manage historic buildings that need energy upgrades but face strict preservation constraints — this project specifically targeted historical buildings with geothermal solutions that minimize structural disruption. Their modular high-temperature heat pumps avoid the need to replace existing heating terminals, which is critical when original radiators or distribution systems are part of the building's heritage value.
Heat pump and HVAC manufacturing
mid-size
Target: Heat pump manufacturer or geothermal equipment supplier
If you manufacture heat pumps or ground source heat exchangers and want to expand into the building renovation market — this project developed improved borehole heat exchangers and modular high-temperature heat pumps designed for retrofit conditions. With 20 partners across 10 countries validating these designs, the technology has been tested across diverse geological and climate conditions, giving you a proven platform to license or co-develop.
Frequently asked
Quick answers
How much can this reduce geothermal installation costs?+
The project's core objective was to reduce overall drilling costs and deep retrofit costs through adapted drilling machines and methods for the built environment. Specific cost reduction percentages are not stated in the available data, but the focus on lower-cost drilling methodologies and avoiding replacement of heating terminals targets the two largest expense items in geothermal retrofits.
Can this scale to large building portfolios or district-level projects?+
The project modelled solutions across 3 climatic zones (North, Centre, South Europe) with 2 insulation levels and multiple building types including single-user residential, multi-user residential, non-residential, and historical buildings. The decision support system and design tools were built to handle this variety, making portfolio-scale deployment feasible across different European conditions.
What about intellectual property and licensing?+
The consortium includes 10 industry partners and 7 SMEs alongside 4 research organizations and 4 universities across 10 countries. Based on available project data, IP is likely shared among consortium members under standard Horizon 2020 rules. Companies interested in licensing specific technologies (drilling machines, heat exchangers, DSS software) would need to contact the relevant consortium partner.
Does this comply with EU building energy regulations?+
The project directly addresses EU energy efficiency goals for building renovation, including the challenging segment of historical buildings where standard retrofit approaches often conflict with preservation rules. The solutions were designed to support different levels of renovation (medium and deep insulation) in compliance with European building standards.
How long does implementation take?+
Based on available project data, the project developed tools specifically to reduce engineering time — the DSS and design tools aim to avoid design mistakes and cut overall engineering costs. The compact drilling machines adapted to the built environment also target faster on-site installation compared to conventional geothermal drilling equipment.
Can these solutions integrate with existing heating systems?+
Yes — this was a specific design objective. The project developed modular high-temperature heat pumps precisely to avoid replacement of existing heating terminals. This means the geothermal system connects to your current radiators or distribution network, which is especially important for historical buildings where replacing terminals is not an option.
Consortium
Who built it
The GEO4CIVHIC consortium is well-balanced for commercialization: 10 industry partners (50% of the consortium) and 7 SMEs signal strong market pull, not just academic interest. The 20-partner team spans 10 countries (Belgium, Switzerland, Germany, Greece, Spain, France, Ireland, Italy, Malta, Romania), covering Northern, Central, and Southern European markets — which matters because geothermal performance varies dramatically by climate and geology. The coordinator is Italy's National Research Council (CNR), a major public research body with extensive technology transfer experience. With 4 universities and 4 research organizations providing the science, and industry partners handling real-world validation, this consortium was structured to move technology from lab to market.
