Near-to-surface geothermal energy

Geothermal energy is derived from the thermal energy generated and stored in the Earth’s interior. In the case of shallow geothermal, the resource for energy is solar heat stored in the earth. This geothermal resource is renewable, as there is a constant heat flow to the surface and atmosphere from the solar radiation.

Near-to-surface geothermal technologies takes advantage of this renewable source for space and water heating by transferring at low temperature the geothermal heat to a pumped fluid through the ground. In warmer climates, this source can also be used in combination with reverse heat pumps as a sink for the heat extracted from the building, reducing the cooling load.

Smarter Together Site Munich

The Munich lighthouse demonstration area is located at the Western edge of the city and includes both the large urban redevelopment area Neuaubing-Westkreuz (350 ha / 30,000 residents) and the flagship new development area Freiham, set to become a model of low carbon development for up to 20,000...

BUILDSMART Site Malmö

The Malmö demonstration site covers four new buildings. The main focus was on the sustainability of the buildings. The following buildings have been constructed: Malmö Live – Hotel building (Skanska) Malmö Live is a new concert, congress and hotel complex situated on walking distance from Malmö...

E2REBUILD Site Voiron

The French demonstration site is a multi-storey building in Voiron in the Isère Department. The building was made of concrete with no insulation. The windows were first generation PVC double-glazing 4-6-4. The building had natural ventilation. All dwellings had an individual gas boilers for the...

DIRECTION Site Munich

The NU-office is the German demo site of the DIRECTION project, located in Munich under a continental climate strongly modified by the proximity of the Alps. The building functions as a rental office building with 11.000 m² distributed in five upper floors and two basements. It has been designed to...
