TECHNOLOGY / CASE STUDIES POST VICTORIAN LUSTRE


Set amongst the towers of Sydney Central Business District the GPO is a prominent piece of Australian architectural history. Point of View and acdc brought lighting to the building’s façade for the first time.

With its classical sandstone and granite carvings, the regal statue of Queen Victoria and the recently restored clock tower bells that ring out Westminster chimes on the hour, the GPO in Sydney is quite a sight to behold. The building had never been illuminated at night as previous light fixtures were difficult to maintain, so PointOfView were appointed as lighting designers in order to reinvigorate the façade and create a lighting scheme to enhance the night time image of Martin Place and its surroundings. The design scope consisted of the re- lighting of the clock tower and façades of Martin Place, George Street and Pitt Street,


with a view to providing a low maintenance solution using discrete LED fixtures. acdc’s Artemis fixture was chosen for the project because of its reliability and compact size, it can also be installed in challenging exterior environments due to an IP68 rating. Artemis offers excellent beam control allowing for the variety of different features to be distinguished. The decorative arches of the colonnade were subtly lit allowing the faces of the Heads of State to be accented. Using light and shade the dentils, statues and carvings are revealed at the mid-levels. This is achieved thanks to an Artemis’ narrow beam grazing the textured stonework, which was previously encased in


darkness. Continuous LED lights softly wash the top balconies, highlighting the detailed forms of the upper levels. The lighting here is subtle whilst providing a sense of strength, anchoring the clock tower. The LED modules required specific binning from acdc to ensure the lighting effect was consistent in colour and colour rendering. As all acdc LEDs are dual binned within a two step MacAdam ellipse there was confidence that this could be delivered. This took many site trials in order to achieve the desired effect with the final selection being tested in a full-scale mock-up. www.acdclighting.co.uk
