The ventilation ducts in the attic were placed on steel platforms leading from the cupolas over the vaults to the ven- tilation stations and finally to the exhaust outlet. The routing of the ducts with a cross sectional area of up to 1,60 m x 1,80 m required an especially careful planning due to the limited space and the premise not to change the roof structure ascribed to Hans Döllgast. Moreover, sound absorbers weighing up to 800 kg had to be positioned in a way that en- sured a load transfer compatible with the existing structures.
