Of hidden helpers – Danish radio concert hall by Jean Nouvel
von | 10/13/2011

There it stands like a glowing blue cube, the new Danish Radio concert hall in Copenhagen. The 45-meter-high and wide building was designed by French star architect Jean Nouvel.

Behind the fiberglass façade is a 24-meter-high concert hall whose structure shimmers through the partly outer transparent facade. While very plain on the outside, the interior is very complex and boasts immense detailing: In the concert halls, for example, no single wall runs at a right angle and all the elements were purpose-made to improve the aural experience. An outsized 75-ton ceiling sail floats above the orchestra pit. Its height can be varied as this serves to adjust the hall's acoustics to the particular performance.

Moreover, countless invisible measures enhance the acoustics, too. The so-called "grid gratings" made by the TTC Timmler company are used for outside drainage and inside ventilation, come with a special cantilever arms that are anchored in the concrete and screed. This technique means that no sound is transferred from the outside into the concert hall. Working to specifications set by Jean Nouvel's architectural office TTC also developed ventilation gratings beneath the revolving doors in the entrances that resemble extremely enlarged LPs.
