TetraEner Site Geneva
One of the first principles of sustainable living is to make the best use of the resources that are closest at hand. Genève is putting this principle into practice using a resource that is right at its doorstep: the water of Lake Genève. The lake´s water – nearly 90 km3 in volume – has a conveniently constant temperature of eight degrees Celsius on the ground. This makes the water an ideal source of energy for heating and cooling buildings of Switzerland´s second largest city.
