The Munich lighthouse demonstration area within the SMARTER TOGETHER project is located at the western edge of the city, and includes both the large urban redevelopment area Neuaubing-Westkreuz and the flagship new development area Freiham, set to become a model of low-carbon development for up to 20 000 new residents and 7 500 new jobs. With the aid of cutting-edge technology and the intelligent use of data, Munich’s objectives are to cut CO2 emissions by more than 20 %, raise the use of renewable energy to above 20 % and increase energy efficiency by more than 20 %.
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.
