Intelligent LED upgrade for Swire Cold Storage

With a network of temperature-controlled facilities across Australia, Swire Cold Storage provides logistics services and supply chain solutions to a range of businesses. The company has made energy efficiency a high priority, with a focus on intelligent LED lighting.

After considering a range of LED products, Swire Cold Storage determined that integrated intelligence - sensing, control and wireless management - was the key to achieving dramatic energy savings. The company elected to implement the Digital Lumens Intelligent LED Lighting System, provided by Maser, for the first stage of lighting retrofit projects at Laverton (Vic), Hemmant (Qld), Lurnea (NSW) and Dry Creek (SA).

Comprising a network of intelligent LED fixtures - all with occupancy sensing, power metering, a microcomputer and wireless networking capabilities - managed by LightRules energy management software, the system provides light only 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 exactly how much energy is being used and where.

Working with Maser, Swire performed detailed audits on second-stage facilities including Banjup (WA), Welshpool (WA), Homebush (NSW) and Clayton (Vic). The Maser team analysed existing 400 W lighting, energy costs, maintenance plans and facility occupancy patterns, then provided recommendations on proposed lighting upgrades, including detailed calculations of potential energy savings. The company also managed the installations and system commissioning to ensure project success.

The system has so far achieved energy savings of over 94% in each of the second-stage facilities. With no maintenance or re-lamping required, Swire Cold Storage is expanding its deployment of the system not only at the third stage of retrofit projects but also to new construction sites.
