They even meet the notoriously finicky requirements for heritage-listed buildings, which have stringent limitations for lighting infrastructure. “Most of the rules are around attachment, so you can only attach to grout lines and things that are replaceable; you can’t drill into stone lintels and things,” says Tan-Hayes, who has been involved in a wide range of heritage façade projects in recent years, including Number One Martin Place and Sydney’s Town Hall. “You never want the fixtures to stand out, especially in existing heritage situations. The advantage of having a smaller fitting is a great one.” The future of façade lighting is a bit of a mixed bag. LEDs will likely continue to dominate the market, but new applications of the technology are set to reshape the way we think about building exteriors. Media facades, or LED screens that attach to a building’s external walls, are one such example, and they’re growing in popularity in many places around the world. In a creative context, media façades have a lot to offer but increasingly they’re being used for advertising (think billboards in Times Square, for example). While they can be aesthetically appealing – the Taman Anggrek Mall in Jakarta boasts the world’s longest media “Floodlighting is what façade lighting was 10 years ago,” says Perry. “Since that time, it has changed a lot, especially in Australia. In the last decade there’s been a greater public awareness of climate change, green and sustainable living and energy prices, and floodlighting these days is not just out of date, but is pretty much considered unacceptable by the public. “With the advent of LED technology, we now have all these new tools that are available to us that are really small, efficient, colour selectable and low maintenance.” LEDs also offer benefits from a maintenance perspective when compared to more traditional lamps. With a lifespan in the tens of thousands of hours, LEDs extend the shelf life of lighting schemes, and also reduce the frequency with which lights need to be replaced, says Bernie Tan-Hayes, a director at creative lighting design consultancy PointOfView. “You stick a halogen light on a façade, it’d burn out in a couple of thousand hours and no one would replace it, the scheme would get patchy. Now, obviously, that maintenance period is vastly extended, and the life of a design is also extended therefore,” he says. Integrated lighting illuminates the architectural features of the Crown Casino’s Eastern Façade, providing patrons with an important first impression before they step inside.
