  1. EGEC Webinair Wednesday 12th December 2018 Cheap and efficient application of reliable Ground Source Heat exchangers and Pumps Giulia Mezzasalma R.E.D. S.r.l. Giulia.mezzasalma@red-srl.com Coordinator: Adriana Bernardi National ResearchCouncil(CNR), Italy InstituteofAtmosphericSciences and Climate (ISAC) GA n. 657982- Duration: 4 years– Start June 1 2015 Total project budget: 5.804.847,50 € EU contribution: 4.844.652,00 €

  2. Project innovations • Thematic geothermal mapping at local scale for better planning of geothermal systems • Drilling machine developments combined with new Ground Source Heat Exchanger (GSHE) designs of co-axial and heat basket type to reduce installation time, increase yield, increase safety, reduce permit needs • Design software for GSHE and heat pumps and Decision Support System (DSS) for optimum selection, design and implementation of complete systemsacross different applications and soil conditions • Novelheat pump with improved performance at higher temperatures to avoid having to change heating terminals in retrofitting of existing/historical buildings and to increase efficiency This project hasreceivedfunding from the European Union’s Horizon 2020 Research and Innovation Program under Grant Agreement number 657982 EGEC Webinair, 12th December 2018

  3. Project Results on month 36 • Tools will be made available as freeware at the end of the project after having been tested and validated in several virtual case studies • The application of helicoidal heat exchangers at larger depths (up to 14 – 15 m) has been developed.This represents a safe alternative for buildings with limited energy requirements or applications with insufficient space for horizontal heat exchangers. • New tools, drilling head and drill bits, were also developed to install co-axial heat exchangers of improved design based on a piling methodology. In several demonstration cases, the potential cost reduction of 20 -30 % has been confirmed in situations where the borehole needs to be supported by casings and/or where the market competition is not well developed. • Novelheat pump has been developed and installed. The performance analysis is ongoing.
