Comparison of Four Methods for Borehole Heat Exchanger Sizing Subject to Thermal Response Test Parameter Estimation

Energies, 2019
The impact of different parameter estimation results on the design length of a borehole heat exchanger has received very little attention. This paper provides an in-depth investigation of this problem, together with a full presentation of six data ...

Thermal Response Testing of Large Diameter Energy Piles

Energies, 2019
Energy piles are a novel form of ground heat exchanger (GHE) used in ground source heat pump systems. However, characterizing the pile and ground thermal properties is more challenging than for traditional GHEs.

Masonry wall panels retrofitted with thermal-insulating GFRP-reinforced jacketing [PDF]

, 2015
Today there is a need to provide thermally efficient walls, while at the same time to increase the mechanical properties of old unreinforced masonry walls that will not require large amounts of energy in the retrofitting or deconstruction processes.

Extending capabilities of Thermal Response Tests in vertical ground heat exchangers: an experiment-based local short-time temperature response factor. [PDF]

, 2020
This work presents a fast and practical method to determine a characteristic function that predicts a local ground response of vertical ground heat exchangers (GHE) in a short term, which is mandatory when intermittent operation modes are modelled.
