Sanitary installations

Also for the further measures, economically viable solutions were sought in order to reduce the operating cost of the building. For instance, cisterns were used for the toilets, which only use 4.5 l of water per flushing. This is a saving of 1.5 l and is possible through a special technology of feeding the water. As a rule, water-saving taps were used throughout. By using special aerators (air-water mixer at the end of the taps), the tapped water is enriched with a high share of air bubbles. This measure achieves a considerable reduction in water consumption with the same or an even improved cleaning performance (for instance, when washing hands).
