Our electricity needs are covered in a CO2-neutral way with 100% Swiss hydroelectric power.
Demand-oriented control and regulation of energy consumption by means of a building management system.
Optimisation of bathing water technology: In 2020, the bathing water treatment system was updated in order to connect it to the building and energy management system. This made it possible to optimise the energy efficiency of the bath water treatment and save around 25,200 kWh of electricity per year.
Conversion from halogen to LED lighting in 2020: Replacement of around 576 light bulbs in the bathrooms in the Main Building, as well as replacement of the corresponding dimmers. The new lamps have a 7 times higher energy efficiency. Further lamps will be gradually replaced with more energy-efficient LED bulbs.
Conversion from halogen to LED lighting in 2021: Replacement of around 80 spotlights in the Main Building, which still require a third of the previous energy.
Further conversion of over 950 light sources from halogen to LED in the rooms, corridors and function rooms planned for 2022. LED light sources consume around 84% less energy than the existing halogen lamps and are also much more durable.
