FAQ - Ventilation of the building
Ground-coupled heat exchanger
The ground-coupled heat exchanger uses (in a passive way) geothermal energy, that is the energy of the ground.
Ground-coupled heat exchanger or Energy Recovery ventilation (EVR)?It is possible to combine both solutions. This combination reduces the energy needed for the heating in winter.
Considering the cost (economic and ecological) of such a facility one should validate the appropriateness of this choice.
If the location is known for long periods (inter-season) during which the outside temperature is close to the comfort temperature and the conception of the building in terms of insulation, exposure and management of solar contributions (in particular) is efficient;
And if one considers the installation and operating costs as well as the maintenance of an EVR together with a ground coupled heat-exchanger solution, they may be irrelevant, both financially and ecologically, in comparison to the generated energy savings.Caution: this is not to exclude any particular solution, but to clarify the relevant issues. Even in the Mediterranean perimeter, such a scenario must be considered in terms of the specific microclimate and the location, orientation and topography of the site.
