Starbucks recently finished replacing nearly all of its incandescent and halogen lighting with LEDs during a two-year roll-out to over 7,000 company-owned stores, most in the United States and Canada, but with some in Europe and Asia. This is the largest deployment yet of LED technology in an application that is very sensitive to the quality of light; Starbucks' success proves that the new digital lighting is ready for mass install.
Jim Hanna, Director of Environmental Impact for Starbucks confirmed that the LED lighting program is on target to slash consumption by more than 80 percent compared to existing lighting. My back-of-the envelope calculations [see notes below] found that
• Each LED light bulb saves approximately $30 annually in energy costs and eliminates the equivalent CO2 as half a barrel of oil;
• Each 1,000 square foot store on average would save nearly $600 annually and eliminate the equivalent CO2 as 10 barrels of oil
To capture these impressive benefits, for both the bottom-line and the environment, it took more than replacing a light bulb. When Starbucks was examining which energy efficiency projects to deploy in its stores, lighting was an obvious choice, since retailers consume a large amount of energy on lighting to provide ambiance and to showcase products.
But Starbucks had already installed energy-efficient fluorescents in many areas of its stores. The remaining halogen and incandescent lights were in its beverage and sitting areas. The soft, warm light provided by incandescent bulbs was critical to creating an inviting experience. And halogens were used to highlight products. Fluorescent was a poor fit in these areas due to its inferior color rendition. Although CFLs are prevalent in offices, older and inefficient lighting technology is common in many retail and other high-end applications.
Starbucks investigated LED lights and appreciated the low energy use and the quality of light, but LED products on the market at the time required replacing both the light bulb and fixture driving costs up considerably.
