Geothermal energy
Heating and cooling with the earth
Careful planning required
Geothermal systems are designed for a service life of decades. As the possibilities vary greatly depending on the location, thorough geological investigations and careful planning are necessary.
The earth is an almost inexhaustible source of environmentally friendly and climate-neutral energy. Its use is on trend and will continue to grow in importance.
The most common method of using geothermal energy is probes that are connected to a heat pump. In winter they draw heat from the ground or groundwater, in summer they are used for cooling. The same effect can be achieved with energy piles, which serve as foundations and heat conductors.
We advise building owners on which system to use, provide support with planning and implementation and assist them with legal issues.

Groundwater heat utilization Kloten (ZH)
Ecosens AG carried out hydrogeological investigations in a district of Kloten for the replacement and expansion of two heating centers in order to use groundwater for heating and cooling purposes. In addition to the geological surveys of the boreholes and planning of the well expansion, pumping tests were carried out and evaluated. Computer-aided thermal groundwater modeling was also carried out using the "Feflow" software to determine the number and positions of the extraction and return wells as well as the mutual thermal influences of the systems. This thermal groundwater modeling was also used to check compliance with the legal requirements for groundwater. more >>

Ecosens AG was able to carry out the hydrogeological investigations for the site development, including the dimensioning of the geothermal probe field in accordance with the current SIA 384/6 standard. For an optimized dimensioning of the geothermal heating system with heating and cooling, a geothermal probe drilling including a thermal response test was carried out. The aim of these investigations is to take into account the local geology and its properties for the optimized dimensioning of the heating system. The local underground temperature, the different thermal conductivities of the rock layers and groundwater-bearing layers have a major influence on the final number of meters of borehole required for the geothermal probe field. more >>
