2050Today, in cooperation with SIG, organizes a visit of GeniLac, the innovative, 100% renewable thermal solution that uses the water of Lac Léman to cool and heat residential, business or community buildings.
GeniLac is made up of two networks, one in an open loop towards the city center which extends to the Rhône, and the other in a closed loop which connects the airport and extends to the Quartier de l’Etang. Other closed loops will emerge in the PAV (La Praille-Acacias-Vernets), Gare des Eaux-Vives and HUG sectors.
GeniLac amplifies and replaces Genève-Lac-Nations (GLN), a first renewable thermal network born in 2008, which made it possible to replace very energy-intensive air conditioners.
SIG exploits the natural and local resource that is Lac Léman. The water is collected from 45 meters deep, at a stable temperature all year round of around 7 degrees. It is then transported in underground pipes to the buildings connected to the thermal network. This is the principle of hydrothermal energy: from this 100% renewable and local resource, GeniLac can replace air conditioners and heat buildings by adding a heat pump. Come and find out!
The visit will allow you to:
The visit will be led by professional guides and you will be equipped with protective helmets. A SIG engineer will answer all your technical questions.
