A lighting retrofit project at California-based McDonald Packaging has resulted in a 24 percent reduction in power consumption.
According to Don Artaserse, vice president and chief financial officer at McDonald Packaging, the result was close to the projections given by Lime Energy, which completed the retrofit.
Artaserse said the 24 percent reduction in power consumption was based on a daily average of kilowatt hours consumed in two three-month periods. Consumption for the full three months was 282,318 kilowatt hours in 2005 compared to 208,630 for the same three month period in 2006, while the daily average was 3,003 kilowatt hours in 2005 compared to 2,293 in 2006, or a 24 percent reduction.
Payback was 1.1 years on the project in the facility which includes 120,000 square feet of warehouse space and another 15,000 square feet of office space. Return on investment was 92 percent. The retrofit was eligible for nearly $26,400 in rebates from Southern California Edison.
