Extravagant design and a sustainable energy concept – architect Karl Heinz Sommer is making a clear statement with the five-star hotel. The Kameha Grand not only convinces thanks to its architecture. It also meets all the demands made on a “green building” as it utilizes passive solar energy, intelligent cooling systems and geothermal energy. Alongside the impressive energy concept, the floor-length windows, which allow a view into the event hall in the hotel’s interior, are fitted and motorized with aluminum blinds of ABBA Protezioni Solari (Italy) and elero drives. Using wall-mounted or hand-held transmitters the guests can set these in line with their individual needs. The JA drives – 514 in total – are fitted with wear-free and noiseless “Soft” brakes and function particularly quietly – an important prerequisite for a perfect combination of comfort, functionality and design.
