The 1st of February 2015 our new employee, Maria Alberdi-Pagola, started an Industrial PhD dealing with our energy piles. This Industrial PhD project is a collaboration between Centrum Pæle A/S, Aalborg University, VIA University https://www.centrumpaele.dk/College and INSERO Horsens and it will last 3 years.
This section of our webpage provides a wide overview of the main steps taken during the PhD project and it will be updated as relevant conclusions are obtained from the on-going research.

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.
