GE LED lighting brings new radiance, energy savings to Marriott Headquarters

Corporate campus saving $120,000 annually

THE SITUATION

Security and energy savings were top priorities when considering new lighting to cover the nearly 2 million square feet (45 acres) of parking and garage space at Marriott headquarters. After testing competitive exterior garage fixtures, parking lot lights and contemporary post tops, Marriott selected GE’s family of high-efficiency Evolve™ LED lighting systems.

THE SOLUTION

GE Lighting LED solutions were recently installed in several locations at Marriott International’s headquarters located in Bethesda, Maryland. The installations have enriched lighting quality, heightened employee security and improved energy efficiency. Following its corporate campus-wide lighting update, Marriott will use 860,000 fewer kilowatt hours (kWhs) of electricity and save more than $120,000 in combined energy and maintenance costs a year.

“We preferred the exceptional light and uniformity of GE’s Evolve™ LED lighting. GE performed a comprehensive lighting audit of our existing system, provided photometric analysis with 3D renderings of the new system, and forecasted our energy and maintenance savings. GE excelled as both a trusted strategic consultant and solutions provider.”

– Jim Young, vice president, corporate facilities for Marriott International, Inc.

More than 230 Evolve™ LED Area Lights now illuminate Marriott’s outdoor lots, while inside the parking deck nearly 400 Evolve LED Garage Light fixtures and several Evolve LED Tunnel Light installations. These highly efficient systems are doing more with less – their advanced technology and optics require less energy and light to provide a more even light distribution than the metal systems they replaced. Marriott also used more efficient GE T8 fluorescent lamps to help light the way for associates to and from the headquarters offices.

In the foyer, special scaffolding is needed to reach fixtures in the high ceiling. Marriott would change the lights, which lasted just one to two years on average, only once a year at a cost close to $3,000. Maintenance savings will now add up after GE replaced 12 90-watt bulbs with 20-watt LED PAR38 lamps. Rated for 50,000 hours of life, GE’s LEDs could keep the scaffolding away for up to seven years.

Seventy-two new GE Lumination® Recessed LED Troffers were added to the building’s lower level. When illuminated, the chic and slim 2’x2’ fixtures produce a perfectly even glow. While off, they appear completely free of a light source to blend in with the ceiling, enhancing the elegant aesthetic of Marriott’s employee space.

THE SOLUTION CONTINUED...

Marriott also gained the functionality to dim its new garage lighting with GE’s ProSys™ Lighting Control system incorporating motion sensors. Light output is reduced to 40 percent while the garage is vacant and adjusts to 100 percent when motion is detected. The control system will interface with Marriott’s video surveillance center, alerting guards to after-hours movement in the deck and focusing the nearest security camera to where motion is detected.

Marriott also coordinated with Montgomery County government officials to replace 32 180-watt metal halide streetlights along the road that serves its headquarters and neighboring companies.

GE also retrofit the ‘Marriott’ sign at the Bethesda headquarters entrance with Tetra® PowerStrip LED lighting, improving maintenance cycles from two to three times per year to once every five to 10 years.

Moving inside Marriott’s 8-floor, 900,000-square-foot headquarters, GE provided:

•7-watt LED PAR20 lamps in all hallways.

•20-watt LED PAR38 lamps in the foyer.

•140 GE 12-watt LED BR30 lamps in the auditorium.

•72 new GE Lumination® Recessed LED Troffers to the building’s lower level.
