Gold Coast Stadium is one of Australia’s newest sporting developments and home to one of its newest stars, the innovative ‘Solar Halo’. As one of Australia’s leading sustainability engineering consultants, Norman Disney & Young provided the engineering expertise for the innovative ‘Solar Halo’. Designed by architects, the ‘Solar Halo’ has been cleverly integrated into the roof to provide 20% of the stadium’s energy requirements, whilst also forming a weatherproof line.

Other distinguishing features of the project Integration into the existing roof design proved to be an interesting task for the team, and a number of options were investigated. The initial option was to mount the panels almost–flat with a uniform leading edge and having the panels sloping down slightly towards the rear of the stands to capture the stormwater. The final solution involved 39 individual bays, each comprising 8, 14 or 18 solar panel mounts over a curved bay. Viewed Solar technology from the front, the bays present as a series of The stadium’s solar panelling uses curved elements best understood by viewing Scheuten Optisol sandwich glass panels, the pictures.
