PH.D.-Projekt

The 10th of September 2018 our employee, Maria Alberdi-Pagola, defended her Industrial PhD thesis “Design and performance of energy pile foundations”.

This Industrial PhD project had a duration of 3 years and it has been a collaboration between Centrum Pæle A/S, Aalborg University and VIA University College, with Innovationsfonden and INSERO Horsens as financial partners.

This section of our webpage provides a wide overview of the main steps taken during the PhD project and it involves all the relevant publications developed during the PhD period.

Thermal response testing (TRT)

Thermal response testing (TRT) is an in situ test, that serves as a tool to dimension ground source heat pump heating and cooling systems. At Centrum Pæle, we are trying to apply TRT to energy piles and use it as a dimensioning tool for energy foundations based on pile heat exchangers. To date, we have developed a 2D finite element model to analyse the TRT data obtained from tests performed in Centrum precast energy piles.

On-going projects: February 2016

Thermal response test of an energy pile instrumented with ten Pt100 temperature sensors, casted in the concrete and placed at different levels, at the new northern extension at Rosborg Gymasium.

December 2015

New building founded on 220 energy piles at Rosborg Gymnasium, Vejle (under construction)

Fall 2015

Thermal response test execution in various energy piles at our test site at Langmarksvej in Horsens.
