D+H supplies special SHEV solution for the “PANEUM – Wunderkammer des Brotes”
Wolf D. Prix, managing director of COOP HIMMELB(L)AU, describes the building – located in the Austrian municipality of Asten – as being “identifiable architecture”. And that hits the nail on the head. The 20-metre tall silver customer-information and event venue is an architectural treat. An exhibition gallery, known as the “Wonder Chamber of Bread”, is situated on the upper floor.
Special constructions demand Special Solutions from D+H
A circular atrium which includes an opaque suspended ceiling and a roof structure is at the centre of the Wonder Chamber. The space between these two sections was not sufficient for the planned drives from D+H. Powerful rack and pinion drives were necessary, because a certain amount of snow load had to be taken into consideration for the roof windows. A special solution was necessary. Michael Mendler, Willenig Sales Manager: “Together with a metalworking company, we developed a traverse solution that was positioned in the suspended ceiling.” Ten ZA 155/500-series rack and pinion drives were affixed directly to this traverse, thereby solving the problem experienced in the closed state, where the bottom was hitting against the suspended ceiling. Using this method, eight chain drives from the KA 34/1000 BSY+ series could also be mounted in the suspended ceiling in such a way that they are not visible from below. The aesthetic demands of COOP HIMMELB(L)AU were thus satisfied. In the event of fire – and also for daily natural ventilation – the flaps open inwards with the aid of the chain drives in the suspended ceiling, and the roof windows open outwards with the aid of the rack and pinion drives.
D+H links SHEV controller with Alarm system
An RZN 4364 plug-in control panel was installed to control in total 18 drives. “It was a part of our remit to link the controller with the building alarm system”, says Michael Mendler. “This means that the smoke extraction is only active when there are people in the building.” This was an explicit customer request, because in this way no unnecessary false alarms could arise and water damage due to unnoticed, open smoke vent dampers would be prevented. Due to the architectural peculiarity of the building and the varying window sizes resulting from this, Willenig programmed each drive separately. Furthermore, a 230 V blind shade was also integrated in some areas.
As already experienced in the cooperation between D+H and COOP HIMMELB(L)AU for the Musée des Confluences in Lyon, France, the requirements for the smoke and heat exhaust ventilation system were high. Thanks to D+H technologies, loaf and soul are protected in the event of fire, and also benefit from the convenience of automated natural ventilation. Breathing freely is thus easy, regardless of how long the visitors browse in the Wonder Chamber of Bread.
