Lighting in Design May-June 2016

feel of the various façades.The lighting design was limited to various pockets or areas of use, with the balance of circulation spaces relying on spill light from the surrounding areas. With the exception of a few fittings, all the lighting elements in this area were also LED. The combination of warm white, visible, vertical linear LED elements and concealed LEDs under stairs and timber decks creates a suffi- ciently lit space for evening use, which successfully acknowledges the design intention. This vibrant public space is enclosed at high level with a canopy or ‘eyebrow’ that embraces the space. As a slight contrast, cool white LEDs have been used on the eyebrow to define it above the warmly lit public space and to allow visitors to clearly read the two very different elements at night. The lighting intentions for the façades and the public space have both been effectively achieved. The building and image-depicting façades are clearly visible at night and from every main freeway into the CBD. People are drawn into the public open space, and it is a hustle and bustle of activ- ity from early morning until late at night, with the combination of striking and subtle lighting effects complementing the vibrant activities and overall lighting design.

and defined beam angles. The result is a high im- pact, low energy design with minimal spill light. To conform to Green Building requirements, the fins are also angled slightly downwards, preventing the LEDs from creating sky glow. The ‘clip-in’ installation method of the LED strips allows them to be replaced easily if required (there are no mechanical fixings on the outside of the building). The power supplies that feed the strips are all housed remotely within the central lobbies on each floor of the building. This results in ease of access as the lifespan of the power supplies is generally less than those of the LEDs. Since the aim of the façade lighting installation was to accentuate and complement the various façade images, or topographical references, being portrayed, the layout of the LEDs was dictated by the outline of each image, so the ‘story’ being told could be appreciated during daylight hours as well as at night. Landscape/public open space The second area of importance to be addressed was the public open space at the main entrance/ piazza area. The intention for this space was to be vibrant and inviting, whilst ‘reinforcing’ the linear
