GE Lighting LED lights help MetLife save $360,000 a year

Greentech Lead America: GE Lighting announced that it has helped MetLife save nearly $360,000 a year by installing Evolve LED outdoor lighting in parking at 10 office locations and switching to more energy-efficient T8 fluorescent indoor lighting at its 650,000-square-foot administrative center in St. Louis.

Combined, these lighting solutions will save MetLife approximately $360,000 a year while consuming about 3.5 million fewer kilowatt hours (kWhs) of electricity.

Beginning in February 2010, MetLife began replacing existing high-pressure sodium and metal halide parking lot lights at eight administrative facilities and two data centers in several states, including New Jersey, Ohio and Rhode Island.

The lots, comprising 700 parking spaces and 100 fixtures on average, are now lit by GE’s ecomagination  Evolve LED Area Lights. Combined, the more than 1,000 Evolve LED Area Lights will reduce MetLife’s electricity use approximately 1.1 million kWhs a year, totaling a $164,000 savings.

Pleased with the progress of its LED parking lot lighting project, MetLife went in search of additional energy savings, turning its attention to new fluorescent office lighting at its 650,000-square-foot administrative facility in St. Louis.

More than 7,000 old T12 fixtures consuming nearly 5.1 million kWhs a year dominated ceilings in the two-story building, home to 950 MetLife associates. GE Lighting experts performed a walkthrough and recommended a simplified design—lamps of many types, sizes and colors would be changed to a single lamp type using one of two ballast types.

Nearly 13,000 GE F28 T8 linear fluorescent lamps were installed at the St. Louis office. The new LFL design also utilizes more than 8,000 of GE’s UltraStart Programmed Start ballasts and a handful of UltraStart dimming ballasts.

GE’s complete office lighting solution saves about 2.4 million kWhs of electricity a year, a $196,000 utility cost reduction. MetLife expects to invest these savings back into the system, possibly adding photo cells, motion sensors and control options to optimize efficiency.
