Summary: University of Galway recently completed a ground source heat pump project as part of the EU-H2020 project GEOFIT. This module will explain the experiences and lessons learned of this pilot. From the design consideration using specialized software, the calculation of the load profiles, to the hydronic design options and analysis methods. The design exercise is put into contrast with the practicalities of budgeting, procuring, and executing the construction works. In this pilot, a novel method of monitoring and optimizing natural resources such as the heat stored in the ground is being installed that makes use of Distributed Temperature Sensing (DTS) fiber optic equipment.
