With a network of temperature-controlled facilities spanning more than 68 million cubic feet across Australia, Swire Cold Storage provides logistics services and supply chain solutions including temperature-controlled warehousing, refrigerated transport, and distribution services to a range of businesses.
Swire Cold Storage is committed to sustainable growth and development as a path to long-term value creation and as part of this commitment, the company has made portfolio-wide energy efficiency a high priority. In fact, by following the Australian Government Energy Efficiency Opportunities (EEO) legislation, the company has achieved a reduction of more than one million kilowatt-hours in the first 18 months of its commitment. One key element of this program is Intelligent LED Lighting, which is reducing lighting energy use across a number of sites.
After considering a range of LED products, Swire Cold Storage determined that integrated intelligence—sensing, control, and wireless management—was the key to achieving a dramatic energy savings contribution from lighting. The firm elected to implement the Digital Lumens Intelligent LED Lighting System for the first stage of lighting retrofit projects at Laverton, Hemmant, Lurnea, and Dry Creek. The overwhelming success of these installations lead to a second and third stage of projects being identified.
Comprising a network of intelligent LED fixtures—all with integrated occupancy sensing, power metering, a microcomputer and wireless networking capabilities—managed by LightRules energy management software, the Digital Lumens Intelligent Lighting System provides light only when and where employees are present. Lights are on in the areas where employees are working and off or dimmed when no one is present. Each fixture reports its power-consumption, occupancy sensing, and on/off/dimmed data back to LightRules, which shows how much energy is being used and where.
Working with Maser, a specialist provider of Energy Efficiency solutions, Swire performed detailed audits on second-stage facilities including Banjup, Welshpool, Homebush, and Clayton. The Maser team analyzed existing 400-watt lighting, energy costs, maintenance plans, and facility occupancy patterns, then provided recommendations on proposed lighting upgrades, including detailed calculations of potential energy savings.
Maser managed the installations and system commissioning to ensure project success and alignment with Swire Cold Storage’s established project goals. By taking an efficient and time-saving approach, the team minimized disruption and costs while performing wholesale lighting upgrades.
The system has met and/or exceeded initial energy savings estimates, provided by Maser with these results:
•Banjup, Western Australia—273,851 kWh per annum or 94.80%
•Welshpool, Western Australia—558,328 kWh per annum or 95.32%
•Homebush, New South Wales—776,977 kWh per annum or 94.01%
•Clayton, Victoria = 111,015 kWh per annum or 95.41%.
With demonstrated energy savings across multiple facilities and no maintenance or re-lamping required, Swire Cold Storage is expanding its deployments of Digital Lumens Intelligent LED Lighting System not only at the third stage of retrofit projects, but also to new construction sites such as the recent Laverton Stage 2 (VIC).
