Centrum Pæle A/S also manufactures energy piles that use the resources from the earth effectively, utilizing geothermal heat technology. The energy pile is a question of sustainability in a double sense, as the pole, in addition to the static load-bearing capacity, will also supply energy produced sustainably.
The energy pile is used for the heating and cooling of buildings and in some cases, for the storage of energy. (especially when going from warm to cold periods).
The energy pile reduces the need for traditional heating and cooling installations and contributes significantly to CO2-neutral construction.
An energy pile typically contains approx. 60-80 meters of geothermal heat hoses. As opposed to traditional, horizontal solutions, where geothermal heat hoses are placed approx. 1.5 meters below the ground surface, the heat from the energy piles is collected vertically through the layers of the subsoil from 1 meter and down to 18 meters below ground.
Energy pile test process in Horsens
To ensure a greater knowledge of the system’s capacity under different geological and seasonal circumstances, Centrum Pæle has tested the energy piles together with VIA University College in Horsens.
The test focused on the following:
- Thermal conductivity in the ground
- Influence of the groundwater level on the capacity
- The capacity of the installation
- Heat pump, flow, and the system setting for the highest efficiency
- The minimum distance between the energy piles
- Seasonal variation in the capacity
- Influence of the pile on the environment
