Stadium design, both discipline and »product«, is facing important changes in the upcoming years. Not only is it already foreseeable that the fight for spectators will sooner or later digitalize the inside, with personal screens, similar to in-flight entertainment screens, showing crucial scenes as an endless replay together with various statistics, personalized for the spectators' interest the moment the ticket has been sold. That just being the peak of the iceberg, also the design approach and design methods will have to change in order to fulfil the constantly increasing requirements in all ways.
At the moment parametric design has clearly the most potential to adapt to all of that, since it is the only tool capable of »understanding« how the machinery stadium works, while providing all the necessary informations/numbers needed for the architectural design or, as a by-product, for other linked disciplines.
A parametric approach means the entire geometrical definition can be controlled numerically. There is no need for remodelling or thinking twice before trying something new, while fearing that weeks of work will be gone just within seconds. A fear that in stadium design isn’t unfounded, seeing the amount of relationships that exist within this building type. Together with the almost endless list of requirements and various trends towards extraordinary forms, those relationships have turned the once massive concrete bowl into a fragile card-house from the architect’s point of view.
