At the 2017 IAKS Congress, a Circle of Experts on Sports Halls met. The participants’ fields of activity ranged from consultancy and the construction and operation of multifunctional spectator installations, research & development on sustainability strategies, quality assurance for the products and systems employed, and the planning and design of sports halls for schools and training.

In the course of the expert discussion, the diversity of sports halls as a building category became evident. And this gives rise to a need for a new, differentiated wording that does justice to this diversity. The concept of “sports hall” currently denotes multifunctional multi-sports events halls as well as specialised sports facilities such as gymnasia, climbing halls or velodromes, and ultimately only inadequately describes these buildings and their functionalities.

This present issue of "sb" shows current outstanding sports hall projects. The international selection describes a thematic arc extending from school sports facilities and a sports campus to a large-volume events arena and demonstrates the physical diversity of the sports hall as a building category.
