Resumé

Ground source heat pump systems (GSHP) are sustainable and cost-effective space conditioning systems based on shallow geothermal energy. A novel way to harvest the energy stored in the ground, is to use foundation piles as ground heat exchangers. Energy piles are standard concrete piles with built in geothermal pipes. Thus, the foundation of a building performs as a structural and a heating/cooling supply element.
This Industrial PhD project investigates the thermal behaviour of energy piles, in terms of pile testing and system sizing, and treats the main thermo-mechanical effects resulted from seasonally heating and cooling the piles. A tool has been developed to assess the thermal dimensioning of energy pile foundations, at a minimal computational cost, which will assist in building more cost-effective installations.
In combination with other renewable energies, shallow geothermal systems based on energy piles have great potential for realising the transition from fossil fuels to renewable energy resources.
