Milaneo Stuttgart: GEZE door technology promotes energy efficiency in buildings

The doors in the shopping centre that have high levels of pedestrian traffic must combine barrier-free ease of access, safety, and attractive design. GEZE delivered a tailor-made solution for all 12 of the vestibules in the three structures, and equipped each vestibule with four automatic doors. The double-leaf automatic swing doors with TSA 160 NT-IS drive systems open and close the door leaves reliably and conveniently, guaranteeing the required security. The integrated TZ 320 safety door control monitors all opening and closing processes, and clears the emergency exits in the event of an emergency. The night-time closer of the exterior doors is also activated by the TZ 320.

As a multifunctional solution, the doors in the vestibule also act as a fresh air opening or air vent for natural smoke and heat exhaust ventilation in the event of a fire. K 600 retractable arm drives push open the doors in the event of fire and keep them wide open for air supply. The automatic swing doors have another benefit in normal operation: they close reliably to improve the building's energy balance. The automatic doors were one of the criteria that helped the Milaneo achieve gold pre-certification from the German Sustainable Building Council (DGNB).

Accessibility, preventive fire protection and emergency exit protection take maximum priority in the basement’s 1,200-space parking area. The answer was a convenient interlocking door system. The doors open automatically in normal operation, but in the event of danger, they create a safe barrier between the car park and the adjacent lift and escape stairwell.

As double-leaf automatic fire protection doors, the exterior doors on the interlocking door system were equipped with Slimdrive EMD F/R IS drives with integrated smoke switch control unit and closing sequence control. Thanks to its low installation height of only 7 cm, the door drive creates an ideal unit with the smoke switch. The guide rails and sensor strip are also integrated elegantly and extremely discreetly into the door system as sensor rails. The Slimdrive security solution was specially developed for slim door profiles and restricted spaces. The Slimdrive EMD-F/R drive also received two Plus X awards in 2014: the innovation prize and the 'Product of the Year' award in the door drives category.

GEZE fitted massive double-leaf fire protection doors with full panic function in the entrances to the technology and logistics area of the shopping centre. Equipped with Slimdrive EMD F/R-IS drive systems and CB flex carry bars, they fulfil the high security requirements of this area. The carry bars ensure that the closing sequence mechanism of the door closes securely every time, even in a panic situation. When opening the passive leaf, the active leaf is opened as far as the closing sequence control waiting position so that both door leaves can then be closed in the correct order.
