Abstract

The market of Ground Source Heat Pumps needs to be increased and one of the barriers is represented by the use of this technology in the retrofit of buildings in urban environments. For this purpose,the H2020 project GEO4CIVHIC has been funded and is currently running. The project develops several solutions for shallow geothermal energy in the retrofit environment, based on the building type, climate and the geological conditions of the underground and considers all aspects of the geothermal system (drilling methodology, ground heat exchangers, grouting, heat pumps).The main objectives are:

• identify and where missing develop modular solutions in drilling (machines and methods)and installing (narrow and reduced spaces), heat exchangers types, heat pumps and other renewable energy/storage technologies, heating and cooling terminals with the focus on each type of built environment (civil and historical);
• generate and demonstrate the easiest to install and cost-effective geothermal energy solutions using and improving existing and new tools.
• Demonstrate the environmental respect and the reduction of CO2emissions in the atmosphere

More efficient ground heat exchangers and cheaper drilling methodologies/machines adapted to the built also narrow environment like the historical centers will be realised. This approach will bring to an easy applicability in thebuilding refurbishment presenting different constraints, to reduce the overall drilling cost in the given geological conditions, to fit in different levels of retrofit (partial or deep). For better meeting the different needs of the retrofitted buildings 6 prototypes of heat pumps will be developed and built up, from high temperature heat pumps (when heating terminals are maintained) up to plug & play solutions (for deep retrofit), thus reducing the retrofit costs.The association of the innovations with different tools like aDecision Support System will enable to find the best solution for each combination of building type/climate/geology to be chosen. Moreover, the design tools will reduce overall engineering costs, avoid design mistakes and form the basis for a major dissemination effort. Application tools will help the users for different practical aspects.The new solutions in the project will be demonstrated in 3 pilot facilities, in 4 real demonstration sites (warm, mild warm, mild cold and cold climates) and in 12 virtual sites. Demonstrations go from partial to deep renovations and include historical buildings.The H2020 project started in April 2018, lasts 4 years with an overall budget of 8.36 M€, accounting 19 partners from 10 countries.
