Ground heat exchanger is a significant part of the ground source heat pumps system with
environment-friendly and energy-saving. The coefficient of performance for the ground …

Integrating heat exchanger pipes with structural foundations in one system has created a
new renewable solution for buildings' thermal loads. However, the interaction between …

Urban areas increasingly suffer from subsurface heat islands: an underground climate
change responsible for environmental, public health, and transportation issues. Soils, rocks …

Underground tunnels used as heat exchangers in the form of energy tunnels can
sustainably meet the thermal energy needs of buildings across city districts. Recently, a …

This study investigates the thermo-mechanical behavior of energy piles equipped with a
spiral pipe configuration. The analysis is based on the results of a full-scale energy pile as …

Shallow geothermal energy pile systems are a novel, low-carbon technology to heat and
cool buildings via heat exchange with the ground. Hydrothermal ground characteristics (eg …

Little is known about the real energy potential of thermoactive underground infrastructures,
such as railway stations, that can act as a heating/cooling provider for the built environment …

This paper presents two in situ experimental investigations of the influence of intermittent
and continuous cooling operation on thermal and mechanical responses of a foundation …

Over the past two decades, the thermo-hydro-mechanical behavior of earth-contact
structures such as piles, walls, slabs, and tunnels, which simultaneously provide structural …

The non-uniform distribution of thermally induced stresses within energy piles presents a
significant challenge when assessing their thermo-mechanical behavior. This study …
