Deep Energy Foundations: Geotechnical Challenges and Design Considerations
… geothermal boreholes have utilized the ground energy for space heating and cooling. In this system, a circulation loop is placed in a small-diameter borehole typically extending to a depth of 200-300 ft. The hole is then backfilled with a mixture of sand, bentonite and/or cement. The loop is …

Numerical Analysis of Thermal Behavior and Fluid Flow in Geothermal Energy Piles
Geothermal heat exchangers are a growing energy technology that improve the energy efficiency of heating and cooling systems in buildings. Vertical borehole heat exchangers (BHE) coupled with ground source heat pumps have been widely developed and researched in the past century. The major …

Thermally-induced ratcheting behaviour of laterally-loaded reinforced concrete energy piles in sand
An energy pile is an energy geostructure that has been increasingly used in practice for supporting and reducing carbon emissions from buildings or other infrastructure. It is subjected to vertical loading from the self-weight of the superstructure above, possibly horizontal loading due to pile …

Ground-Source Bridge Deck Deicing and Integrated Shallow Geothermal Energy Harvesting Systems
Shallow geothermal energy (SGE) systems are becoming increasingly popular due to both their environmental and economic value. By using the ground as a source and sink for thermal energy, SGE systems are able to more efficiently heat and cool structures. However, their utility beyond structural …

Thermo-Mechanical Behavior of Energy Piles: Full-Scale Field Testing and Numerical Modeling
Energy piles are deep foundation elements designed to utilize near-surface geothermal energy, while at the same time serve as foundations for buildings. The use of energy piles for geothermal heat exchange has been steadily increasing during the last decade, yet there are still pending questions on …
