GE Lighting LED solutions were recently installed in several
locations at Marriott International’s headquarters located in
Bethesda, Md. 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.
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. (Photo: GE)
Enhancing outdoor security while saving money
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.
“We preferred the exceptional output and uniformity of GE’s
Evolve LED lighting,” says Jim Young, vice president, corporate
facilities for Marriott International, Inc. “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.”
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—as well as more efficient GE T8 fluorescent
lamps—help light the way for associates to and from the
headquarters offices. Collectively, a 280-watt reduction per
outdoor lighting fixture will cut electricity use by 580,000 kWhs a
year, equating to $70,000 in utility cost savings.
“GE’s considerable portfolio of exterior lighting products
includes many aesthetically attractive fixtures offering long life,
durable construction and an assortment of beam spreads to suit a
wide variety of applications,” notes Steve Briggs, vice
president of product management and marketing for GE Lighting
Solutions. “Our LED area lights consume between 97 and 220 watts
and were designed to replace traditional 400- to 1,000-watt
high-intensity discharge (HID) systems that can spill and waste
light.”
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. Alone, this precise control will produce nearly $11,000
in energy savings (88,000-kWh reduction) each year. And, 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.
With the first cost of GE’s 106-watt Evolve LED Roadway Cobrahead
fixtures covered by Marriott, the county will see an immediate
benefit: using 10,000 fewer kWhs each year provides a $1,200 annual
energy savings.
Investing in indoor Illumination
Moving inside Marriott’s eight-floor, 900,000-square-foot
headquarters, GE replaced 1,000 65-watt bulbs with 7-watt LED PAR20
lamps in all hallways. The 58-watt difference will mean a nearly
$18,000 difference (150,000-kWh savings) in electricity expense
over 261 working days.
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.
Meanwhile in the auditorium, combined halogen and compact
fluorescent lamp (CFL) lighting was inadequate for Marriott’s
advanced dimming system. While the halogen lights could be
darkened, the CFLs could not. A total of 140 GE 12-watt LED BR30
lamps improved the functionality of the space, producing a fully
dimmable system with higher light levels and more light uniformity
in addition to $2,300 in energy savings.
Seventy-two new GE Lumination® Recessed LED Troffers were next
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 that includes a daycare and cafeteria.
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.
Rapid returns
Marriott’s comprehensive LED update will decrease annual
electricity use by 66 percent (680,000 kWhs outside; 180,000 kWhs
inside) at its headquarters, slashing energy expense an estimated
$104,000. Maintenance mitigation will yield an additional $210,000
savings over the next decade for a total return exceeding $120,000
a year. Marriott will also receive more than $130,000 in utility
rebates and EPACT savings. All told, the anticipated payback period
for the lighting project is slightly more than two years, based on
combined electricity, maintenance and labor reductions.
“Marriott has demonstrated its commitment to minimizing the
environmental impact of its business operations many times
throughout this project,” Briggs says. “For GE it’s been a source
of great pride to help Marriott achieve its goal of reducing energy
consumption by 25 percent per available room by 2017.”
