MetLife benefits from energy savings upgrade for office and parking lot lighting

GE T8 Linear Fluorescent System and Evolve™ LED lighting will save MetLife $360,000 a year THE SITUATION

MetLife recently completed a comprehensive lighting update in an effort to reduce energy costs and improve overall lighting quality at its 650,000-square-foot administrative facility in St. Louis as well as in parking lots at 10 locations. Working with GE Lighting, MetLife upgraded to T8 linear fluorescent office lighting and LED outdoor lighting.

THE SOLUTION

GE Lighting experts performed a lighting audit of MetLife’s office, recommending a simplified design for the two-story building. MetLife replaced old T12 fixtures with GE T8 linear fluorescent lamps, creating an average 58-watt savings per fixture.

In total, this switch saves MetLife about 2.4 million kilowatt hours (kWh) of electricity a year—a $196,000 utility cost reduction (based on an $.08 kWh rate and 5,600 hours of operation).

The new linear fluorescent system design uses more than 8,000 GE UltraStart® Programmed Start (PS) ballasts and a handful of UltraStart dimming ballasts to provide a ‘soft start’ that can significantly extend lamp life as opposed to standard instant start ballasts. They also provide greater energy-savings potential when used in a lighting design that incorporates occupancy sensors, daylight harvesters or other automated light controls.

GE’s Evolve LED Area Lights are expected to outlast old HID lamps in parking lots significantly.

“ It gave us great peace of mind to know our employees had that added security when arriving at work and heading home at night.” - Chambers

THE SOLUTION CONTINUED...

In addition to office lighting, MetLife has replaced existing high-pressure sodium (HPS) 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 Evolve LED Area Lights.

“ We think we’re on the cutting edge of this technology and among the first Fortune 500 companies to commit to LED lighting in its lots. MetLife has taken big steps to meet its environmental goals this past year with help from GE and its lighting solutions.”

- John Chambers, Assistant V.P. of Facility Services and Sustainability, MetLife

GE’s Evolve LED Area Lights will reduce MetLife’s electricity use approximately 1.1 million kWh a year, totaling an annual $164,000 savings (based on a $.15 kWh rate and 4,380 hours of operation). They also anticipate much less maintenance: MetLife had replaced about 25 percent of its old HPS and metal halide area lights each year, costing tens of thousands of dollars. GE’s Evolve LED Area Lights are expected to outlast the old lights significantly.

Combined, GE’s office and parking lot lighting solutions will save MetLife approximately $360,000 a year while consuming about 3.5 million fewer kWh of electricity annually. Plus, total project payback will be achieved in less than five years for MetLife’s new LED-lit parking lots and in a little more than two years in the St. Louis office.
