by Shane Henson — September 14, 2011—Groom Energy and Digital Lumens recently announced the installation of the Digital Lumens Intelligent Lighting System in three newly expanded Interstate Warehousing facilities located in Indiana, Ohio and Tennessee.
Working closely with facilities engineers from Interstate, Groom Energy, a provider of commercial and industrial energy solutions, analyzed the existing lighting, selected the Digital Lumens Intelligent Lighting system, designed the new lighting layout, developed the control scheme, and commissioned the systems at all three facilities.
The Digital Lumens System turns lights on instantly in Interstate Warehousing’s freezers as operators enter the aisles and off after they leave, maximizing savings. The mesh networked lighting system continuously tracks and reports energy consumption and savings, and also allows easy overrides to turn lights on for maintenance or inventory.
According to Groom Energy, the systems have exceeded target light levels and lowered the operating costs more than expected. The new sections use 90 percent less lighting energy than the older portions of the facilities, costing $0.04 per sq. ft. to light versus as much as $0.51 in the older spaces. As a result of the significant savings, Interstate said it plans to upgrade to the Digital Lumens System in all of its refrigerated warehouse facilities to help meet energy efficiency goals.
Facilities and energy management personnel from other companies who are focusing on reducing the amount of energy expended to light their facilities may benefit from a similar energy analysis and lighting retrofit from Groom Energy and Digital Lumens.
