Erdwärme macht aus der Vision Wirklichkeit

Wie wollen wir in Zukunft bauen, leben, wohnen und arbeiten? Die Antworten sind im Süden Zürichs zu finden. Denn hier zwischen Zürichsee, Sihlwald und Uetliberg entsteht Greencity: das erste zertifizierte 2000-Watt-Areal der Schweiz. Photovoltaikmodule auf den Dachflächen  versorgen unter anderem die Wohn- und  Geschäftsgebäude mit CO2-neutralem Strom. Energetisches Herzstück sind jedoch die zwei grossen Geothermiefelder mit insgesamt 215 JANSEN geotwin Erdwärmesonden à 220 Metern. Diese übernehmen rund einen Grossteil des Wärme- und Kältebedarfes und sind über die Hauptzentrale in ein Fernwärme- und Fernkälte-Leitungsnetz eingebunden. Der Betrieb erfolgt in einem innovativen Energie-Contracting durch ewz Energielösungen. Die Einbringung der Sonden ins Erdreich übernahm das spezialisierte Bohrunternehmen Broder AG aus Sargans.
