One Central Park – Heliostat

One Central Park was designed by French architects Ateliers Jean Nouvel and PTW Architects.

It comprises two towers of 16 and 33 storeys, above a five-level retail and recreation podium.

Jean Nouvel’s design concept called for dappled light in the building’s interior. To achieve this, TILT designed a heliostat reflector system cantilevering from the upper levels of the eastern tower.

The heliostat incorporates an innovative system of fixed and motorized mirrored panels designed to capture sunlight and redirect it into the retail atrium and onto the landscaped terraces. At night, the heliostat’s integrated lighting displays video interpretations of Sydney landscapes.

TILT was contracted to Watpac to Design & Construct the 42 x 6.25 sqm Sun Tracking Heliostats (on the rooftop) and the 320 x 1.5 sqm Reflector Panels (suspended beneath the main cantilever). TILT also developed the lighting plan and risk minimisation strategies.

The broader Central Park development occupies 5.8 hectares of Sydney in Chippendale and is the visionary redevelopment of the old Carlton & United Brewery site, bordered by Broadway and Abercrombie Streets.
