In designing the expansion of the Cairns Convention Centre, COX Architecture had an opportunity to reframe and reposition the building in relation to its stunning outlooks of both the Trinity Inlet and the city’s dramatic, verdant mountain range backdrop.

The building

This expansion created an additional 10,500 square metres of function space including an expansive undercover area featuring lush plantings and accents of Queensland timbers in the Porte Cochere; a new main entry; 450-seat plenary lecture space; three 120-seat meeting rooms; exhibition space for up to 30 display booths; a 500-seat rooftop banquet space, and a sky terrace.

The curve of the building embraces the panorama, with a 130-metre-long façade featuring a sunscreen fabricated from glass reinforced concrete (GRC) that has been oriented with the aid of computer modelling to track the sun’s path and provide strategic shade to prevent excessive heat gain.

The glazed curved wall required the incorporation of a substantial number of mullions to ensure structural strength for cyclonic conditions. The vertical elements also contribute to the aesthetic of the façade externally and to the internal material language with their timber cladding created from trees cleared for mining at Weipa and reclaimed by the First Nations Traditional Owners.

The requirement

In every detail, the Cairns Convention Centre is deeply embedded in place. This is not, however, without its challenges. Managing the effect of the sun is essential to ensure comfort, amenity and energy-efficiency – and to protect artworks and the interior from UV damage for many years to come.

Bastiaan Kolff, project architect, COX Architecture, explains that blinds have long been important to tropical architecture for shielding interiors from excessive light and heat. For this project, finding the balance between controlling light and allowing view was “critical to success”.

The solution

Verosol blinds were chosen as a solution for the Exhibition area, the Plenary, the meeting break-out area and the Trinity level.

Depending on the functional requirements of the space, the chosen blinds were either 231 Veroscreen roller blinds, featuring a semi-transparent fabric, so the blinds reduce both glare and heat transference while still allowing the glorious outlook to be seen; or a double blind system incorporating both the 231 Veroscreen plus a blackout blind using 737 Veropaque blockout fabric, a flame-retardant fabric, which provides complete privacy and light control, with eliminated light spill.

To ensure that the final result met both specifications and requirements, custom brackets were designed in collaboration with the architect and Lendlease. Further customisation was undertaken with the integration of side channels into large timber pillars to accommodate 5.5m over-height drops of the blinds.

So that technical, aesthetic and operational requirements could all be achieved, COX Architecture specified Verosol Ambience heavy duty motorised roller blinds for both single blinds and double blinds, and which are controlled by a small-scale Somfy automation system, enabling seamless raising and lowering of the blinds as required to match the specific activities planned for the space, time of day or weather conditions.
