An innovative automated external solar shading solution was chosen for the striking peaked atrium of the Grand Central Shopping Centre in Toowoombah QLD. In order to deliver the highest possible reductions in solar heat gain through the atrium under peak solar loads, 28 x Varioscreen® Retractable Sunroof systems were installed.
Depending on the fabric specified an automated external shading solution can reduce energy transmission by up to 85%. In this instance a bright blue heavy-duty sunscreen fabric was chosen so that even as clouds roll overhead shoppers are presented with an inspiring vision at all times in this the premier shopping centre of the Darling Downs.
The European-designed Varioscreen® uses an integrated positive lift system to drive the front bar and keep the fabric under constant tension. The structural design of the Varioscreen® gives unsurpassed stability and strength and allows complex installations such as a unique “bottom -up” opening design achieved here. Available in widths of up to five metres with a projection of up to six metres, two systems may be coupled to give a total width of eight metres. Powdercoated hardware and a huge selection of European and locally sourced fabrics mean Helioscreen’s Varioscreen® Retractable Sunroof can meet almost any design brief.
