Al Janoub Stadium, commissioned for the 2022 FIFA World Cup, incorporates an operable roof to shade the field of play. Passive design principles along with detailed computer modelling and wind tunnel testing maximises the effectiveness of the enclosure for player and spectator comfort. Reflecting Al Wakrah’s maritime heritage, the design incorporates local cultural references combined with practical responses to climate, context & functional requirements. 40,000 seats for the World Cup will be reduced to 20,000 seats after 2022 - optimum capacity as home ground to the local professional team.
