WEBINAR Energy Geostructures

On 25 March from 16.30 to 18.00, KIVI Geotechnics is offering a webinar on Energy Geostructures. During this webinar, Jacco Haasnoot of CRUX and Phil Vardon of TU Delft will give a presentation on energy dam walls and piles. The webinar offers insights into the design of energy geostructures and research on geotechnical and thermal behaviour.

Register via the KIVI website, the link for participation will be sent via email later.

Below is the programme:

Energy sheet piling - test and application

ir. J.K. (Jacco) Haasnoot, sr. specialist/director CRUX Engineering

Using an energy sheet pile, energy can be extracted from the environment so that, with the help of a heat pump, buildings can be heated or cooled. The heat is extracted from the soil as well as from surface water, with surface water in particular providing a relatively large amount of energy. The presentation discusses the (intermediate) results of a trial with an energy dam wall in the Schie near Delft and the feasibility of this system in a historic, water-rich city centre like Amsterdam. CRUX Engineering is working in on the energy dam wall together with Gooimeer BV, Groep Duurzame Energie, TU Delft and TU Eindhoven.

Energy piles and obtaining thermal properties of the ground

Dr P.J. (Phil) Vardon, Associate Professor Geo-Engineering TU Delft. Department lead Geothermal Science and Engineering.

Heat and cooling are responsible for 50% of the primary energy use in the Netherlands. To move towards low carbon heating and cooling, shallow geothermal energy can play a major role. Energy geostructures can play a significant role in in reducing the initial costs of shallow geothermal energy but require a higher level of design, due to the combined structural and energy functions. I will present current research on the geotechnical performance of energy piles and the thermo-mechanical behaviour of soils. This work is aiming towards reliable methods to design energy piles. In addition, I will present new methods on obtaining thermal properties of the soil for energy geostructures, which fit into standard site investigation methods.
