ENERGY BARRETTE | 2020
WHAT IS THE THERMO-HYDRO-MECHANICAL BEHAVIOR OF ENERGY BARRETTES?
The ENERGY BARRETTE project investigates the multiphysical behavior of energy barrettes: innovative underground structures that function as shallow geothermal heat exchangers for providing renewable heating and cooling to tall buildings.
The project integrates experimental and computational simulation techniques to unravel essential aspects of the behavior of energy barrettes: on the one hand, the influence of operating conditions on the amount of thermal energy that can be harvested from the ground; on the other hand, the impact of thermal loads associated with a geothermal operation on the mechanical response of such foundations.
The results of this project will advance the current knowledge in mechanics and energy, and contribute to understanding and predicting the behavior and performance of energy barrettes for their future massive application worldwide.
