Retrofit : Volume 3 Issue 1 2014
14 • RETROFIT AUSTRALIA • VOLUME 3 NUMBER 1 2014 | Lighting Tyres 4 U, one of the tenants at Australand's 5 Star Green Star certified Key Spec 1 industrial facility in Keysborough, Victoria, has reduced electricity usage on a per square metre basis by 55 per cent, when compared to its previous facility. This has also resulted in a total saving in electricity costs, despite more than doubling the size of its warehouse. Jeremy Lane, Branch Manager at Tyres 4 U, says, 'We have noticed about a 40 per cent decrease in our total electricity bills.' Analysis suggests that electricity and maintenance savings from the efficient lighting system installed in the facility will be in the order of $325,000 over the first 10 years of operation. 'In office tenancies, a base lighting scheme is usually provided that doesn't account for furniture layout,' says Anderson. 'This can result in lighting being located where it is not actually required. Removing tubes from fittings altogether can look unsightly, but removing one tube from a twin-tube fitting in areas such as glazed perimeters or walkways between workspaces is a quick way to reduce power. Where lighting controls have been installed or lighting circuits have been grouped thoughtfully, try setting lighting levels lower or turning off some circuits.' Lighting technology is moving at a rapid pace, with a diverse range of options available to replace and retrofit outdated schemes. 'LEDs are the great new hope, and hold considerable promise with their ever-increasing light quality, life spans and efficiencies,' Anderson says. 'However, with advanced technology comes greater complexity. Not all LEDs are created equal, and there are a lot of poor-quality products in the market that make bold claims. It is always worthwhile to do some research before retrofitting a scheme,' David says, suggesting that building owners should check out Lighting Council Australia's fact sheets for more information (www.lightingcouncil.com.au). Doing your homework before embarking on a lighting retrofit makes sense -- and can help you to uncover a range of incentives and financing arrangements to make the retrofit cost-effective. A lighting retrofit at 10 Valentine Avenue in Parramatta, for example, was undertaken under the first Environmental Upgrade Agreement (EUA) in New South Wales. Parramatta City Council and building owner Australian Unity were the first to sign an EUA under the New South Wales Government's new financing mechanism. The lighting upgrade involved replacement of all original light fittings with energy-efficient options, including LED lighting in corridors, and motion sensors in all single offices, meeting rooms and closed spaces. The retrofit, which took six weeks to complete, has vastly improved the quality of the office space, cut emissions by 550 tonnes per year, and will save the tenant around 70 per cent on energy costs -- or around $130,000 per year. Under this EUA, the tenant pays 43 per cent of the cost of the upgrade (over five years) and, by the end of that period, is expected to save up to $200,000 per year. The building owner gets an improved asset, while the local council supports an initiative that makes a sizeable cut to greenhouse gas emissions. So if 'many hands make light work', the many solutions available today -- technical, behavioural, architectural and financial -- are making our lighting work for us at last.
