Au sports centre, Münchenstein
The example of the Au sports facility illustrates the very specific issues of sports grounds. Due to the length of the supply lines, particular attention must be paid to the voltage drop and the short-circuit current. For a lighting calculation, the guidelines of the sport being played are decisive, and the required illuminance levels must be complied with depending on the league and the competition being held. If there are even TV broadcasts, considerable lighting measures are necessary. This determines the number and mounting heights of the candelabra, which are included in lightning protection considerations due to their free-standing nature. If candelabras have to be replaced, the installation often involves the spectacular use of huge pneumatic cranes or even helicopters.
