Resumen

The main aim of EU funded project GEO4CIVHIC is the development, growth and spreading of more efficient and low-cost geothermal systems for conditioning retrofitting civil and historical buildings. Within this context, the assessment of the most suitable drilling technique to install borehole heat exchangers (BHE) is affected by the local geological, hydrogeological and thermal conditions. In order to provide professional (i.e. drillers, designers) and decision makers (i.e. building owners, policy makers) with preliminary information about expected drilling-time and costs for different geothermal systems, drillability maps at European and municipality scale are here presented.
