The specification for the main auditorium called for high-volume air flow — with no draughts and, most importantly, no noise.
Lindab’s approach was to build full-scale models of the opera house’s stalls and balcony at its laboratory in Farum, Denmark. Lindab was then able to carry out full-scale development trials, measure the performance of the system before it was built and prove that it could do the job.
Jørn Treldal of technical consultant Rambøll was responsible for all HVAC installations. He explains, ‘The opera house has probably been the most complicated project I’ve been involved in. The architectural ambitions were extremely high, and the sound requirements for the main auditorium were anything but simple. Lindab was selected by a clear margin; it was the best technical solution.’
The Lindab ventilation units consist of a box with a perforated rear and a black powder-coated grille at the front. Because of the curvature of the hall, each of the 1700 diffusers for the main auditorium has to be individually designed for a specific seat.
