When it was time for a San Diego, Calif.-based cold storage company to expand, the owners decided to seek Gold LEED certification. Among the ways they decided to save energy inside their new refrigerated storage warehouse was to install LED lighting.
 
Officials with Innovative Cold Storage Enterprises, Inc. were going to use 321 traditional high intensity discharge (HID) lights, which consumed approximately 465 system Watts each.
 
Instead, they opted for BetaLED fixtures, which included 230 LED fixtures at 86 system Watts each and another 49 LED fixtures at 321 system Watts each.
 
The warehouse consumed 76 percent less energy using LED fixtures instead of the originally planned HID lights. Additionally, the BetaLED lights provide over 150,000 maintenance free hours in the minus 20 degree Celsisu refrigerated warehouse. The longer lifetime is particularly useful in this application, where replacing lights would otherwise be laborious and expensive because of the 60-foot ceilings.
 
“Utilizing the BetaLED fixtures was a final touch to an already phenomenal project concerning energy savings. We sought to pursue energy efficiency in every facet, as well as cutting edge technology, which is clearly demonstrated in the application of these industrial LEDs,” said Phoebe Hamann, green building specialist, LEED AP for Hamman Construction, which handled the warehouse project.
 
In all, the various energy-saving steps taken during construction mean the 132,000-square foot warehouse costs half as much to operate as the old ICE facility, yet it can hold four times more product.
 
About the LED lighting installation:
 

• A total of 49 (321 Watt) THE EDGE LED canopy lights were used for freezer staging and the dock area. The freezer aisles feature 230 (86 Watt) THE EDGE LED parking structure lights.
•  
• The BetaLED total system consumes 76 percent less energy than the originally designed HID system. BetaLED luminaires provide over 150,000 maintenance-free hours in the minus 20 degree Celsius refrigerated warehouse.
•  
• With the help of THE EDGE fixtures, the ICE II freezer warehouse uses 62 percent less electricity than standard cold storage facilities.
