Cooling
Cool water from the depths of Freiburg is used for the energy-saving air-conditioning of our hotel. From a depth of 24 meters, a pump draws approx. 10°C cold water from the hotel’s own suction well in the courtyard and supplies a sophisticated heat exchanging system. Through a pipeline system in the hall ceiling, the cool water circulates into every single room and is then discharged into the earth with a maximum of 16°C where is cools down again. Therefore, it is absolutely not required to install energy-intensive air-conditioning systems.
Water
Water is a valuable asset. This is why our aim is to not pollute water unnecessarily and to reduce the consumption as far as possible without restricting our guests’ comfort. Apart from the measures in the guestrooms, this aim is, among other things, achieved by (only) changing the towels when required as well as by the use of cleaning agents that are environmentally friendly and perfectly adjusted to the level of hardness of the Freiburg water. Sparkling clean rooms and public spaces are taken for granted in our hotel. And we achieve this without having to use harmful disinfectants and flush toilet rim hangers. And due to the fact that rainwater may seep away easily on the paved and non-sealed surfaces in the hotel courtyard we additionally avoid an unnecessary strain of the sewer system.
