Automatic doors in the new experimenta
Newly opened in April 2019, the experimenta Science Center focuses on learning, research and experimentation, so automatic doors by GEZE were a natural inclusion. The futuristic architecture of the new building and the constant high numbers of visitors demand automatic sliding doors and glass swing doors with very special characteristics. And GEZE has delivered, with its flexible series programme and professional skill to make even a specific swing door solution quite simple. The automatic swing and sliding doors fit perfectly into the glass façade and the transparent interior. They support accessibility and safety in a building worth living in.

The experimenta’s exciting programme encourages a love of knowledge and delight in experimenting. Even the architecture of the new building is experimental. The six floors are twisted against each other as a 'spatial spiral' - a transparent structure with five façade sides each. They are made completely of glass.
Glass sliding doors create visual consistency
The glass façade at the main entrance features an automatic sliding door system as an aesthetic feature that is at the same time discreet enough not to interrupt the consistent glass design. GEZE made its contribution with an innovative automatic sliding door with integrated all-glass leaves (IGG). The door profiles are not visible on the glass surface, as they can be found between the panes. Neither does the door drive interrupt the discreet design. The Slimdrive SL NT IGG drive is only 7 cm high and easily disappears into the glass façade.
Door aesthetics combined with energy efficiency
Further benefits of the Slimdrive SL NT IGG sliding door system include energy efficiency and the prevention of heat loss in the atrium. The plastic frame, invisibly integrated between two flush panes and reinforced with glass fibres, enables thermal separation of the door profiles. This means that the large door leaves contribute to thermal insulation at the façade entrance, and subsequently, to climate protection as well.

Sliding doors ensure accessibility and safety
The experimenta expects to welcome 250,000 visitors a year, even more than for the previous successful exhibition. When schools, groups and families want to enter and exit the new building conveniently, accessibly and quickly, the doors of the main entrance must endure genuine stress tests. Automatic sliding door systems, with the tried-and-tested door drives from the Slimdrive series, are designed for permanent opening and closing operation: reliably, gently and quietly.
Where large groups of people come together, safety is the top priority. The large and wide sliding doors meet the highest safety standards for persons. Equipped with the Slimdrive SL NT-FR drive variant for emergency exits, the building can be exited quickly and accessibly in the event of danger.
For the best automatic doors right from the start
Four years of planning and construction lie behind the new experimenta, creating an extended offer which looks even further to the future. During the planning of the building, project experts from GEZE became involved with the project from an early stage. With their professional skills and experience in architecturally challenging, highly frequented exhibition buildings, they were able to develop ideas from the beginning, work on suggestions for all possible door solutions, and subsequently create an efficient network for exchanges between architects, specialist planners and all parties involved in the construction. This led to the realisation of aesthetically pleasing automatic doors that also meet the structural and safety requirements of door usage.
Automatic swing doors are multi-functional and visually uniform
Uniform design, ease of access and functionality are among the most important demands for the large number of automatic swing doors in different designs in the spatial spiral, which lead to the exhibition rooms and creative studios.
The highlight and all-round talent of the GEZE swing door drive portfolio for swing doors offers a uniform appearance combined with different functionalities. Powerturn door drives have a slim design (7 cm drive height, exactly the same as the Slimdrive drives for sliding doors), offer a variety of functions, and can be integrated into a wide variety of door systems. They also open large and heavy doors soundlessly and safely - fully automatic, by push button or manually. Even children can open the sometimes heavier fire protection doors easily by hand thank to the Smart swing function as opening assistance.
GEZE solution expertise for fire protection doors with individual functionality
Thanks to the opportunities that GEZE is naturally able to offer when developing and designing door systems, fire protection doors have become a reality, with Powerturn drives with a very special functionality. For example, in escape route stairwells, currentless, safe closing of doors in the event of a fire (this is stipulated by strict fire protection regulations!) must be combined with accessible door opening.
However, one of the resulting challenges was that the air pressure caused in the event of a fire for the safe extraction of smoke makes it more difficult for people escaping to manually open the doors. As a solution, the doors were automated by installing Powerturn door drives. With a special control unit developed by GEZE, the doors open automatically with the push of a button, even in the event of a fire, and close again safely after use.

Unique promotion of education and science
The experimenta Science Centre is a project by the Dieter Schwarz Foundation, which is committed to the fields of education and science. Today, it intensively promotes the things that make the community of tomorrow stronger; the expansion enables to extend successful formats such as student courses, and to offer a wide variety of new knowledge formats.
