In order to demonstrate the GEOFIT’s EGS, technologies and tools, and deploy GEOFIT’s IDDS framework into the retrofitting operations three different scenarios, involving 5 Pilot buildings and 4 different climate zones have been conceived:


Urban retrofitting

Geothermal based building retrofit market are currently extended to residential buildings (specially in isolated ones)- large spaces and low energy demand and easy planning options. However, geothermal based building retrofitting works become a challenging issue, when are addressed to non- isolated C&I buildings (offices) in urban or peri-urban locations, with low space available, high energy demand and limited project & commissioning planning options.


Retrofitting with rock drilling scenario

Drilling through hard rock has been a limiting factor to economically develop significant geothermal projects in several areas. The high cost and need for new technology development has been the key factor to be overcome. Problems faced while drilling hard rocks are not only restricted to slow penetration rate, but also the non-productive time associated to drill string failure, wellbores out of gauge, stuck pipe associated to block instability that falls into the well, and fluid losses due to fractures. Through proper technologies and modelling methods, GEOFIT have potential to improve hard rock drilling performance and the associated problems enabling fasters methods for the cost-effective installation of Geothermal systems. Not only technologies to improve the rate of penetration, but also ways of reducing the vibration levels have been mapped in the project, and will be field tested.


Seismic retrofitting in historical buildings

While within incentives for public and private investments set up by EU countries in the field of energy efficiency and environmental quality have allowed an increase of national retrofitting programs, the same cannot be said for what concerns the introduction of measures for the mitigation of natural hazards such as earthquakes. New methods, tools and techniques to enabled the building retrofitting market in EU- areas with seismic risk. Furthermore, while energy and cost efficiency solutions are widely acknowledged in new constructions, a still deep multidisciplinary interaction is required in case of retrofitting of historical building with cultural heritage value to be preserved, and more urgent in the case of seismic risk. Such value typically represents a huge constraint to face during the course of design and construction phases, and therefore tailored low-impact solutions have to be designed and integrated to fit case-specific boundary conditions. Historical buildings represent almost one third of the construction panorama in most of European countries, so given the massive contribution of such buildings on the overall final energy need and GHG emissions imputable to the construction sector, such category cannot be neglected in designing energy efficiency retrofit actions with a deep multidisciplinary interaction in the field



Three of the pilots belong to educational centres or universities (Italy-UNIPG, Ireland-NUIG, France-NBK), some of them located on university campuses (NUIG, NBK). The pilots are (and will be) open to the general public and – according to the communication plan – general public can visit openly or on a guided tour under the supervision of the consortium. This will allow to open to the public, students and professionals, the new innovations, being able its observe operation for educational purposes. In turn, through the WP of communication, information leaflets will be provided to the different educational centres involved in GEOFIT.
