Marriott Headquarters, located in Bethesda MD, recently completed a LED retrofit project utilizing state-of-the-art GE Lighting LEDs. The installation has improved lighting quality, enhanced security, and greatly reduced energy consumption. Marriott HQ will now use 860,000 fewer kilowatt hours (kWhs) of electricity and save more than $120,000 annually in energy and maintenance costs.
For Marriott, security and energy savings were top priorities when considering new lighting for their nearly 45 acres of parking and garage space at corporate headquarters. After comprehensive product testing, Marriott chose GE’s family of high-efficiency Evolve™ LED lights.
“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.”
Now, more than 600 Evolve lights illuminate Marriott’s outdoor parking, garage, and tunnel areas. Additionally, more efficient T8 fluorescent tubes were installed to provide further energy savings in preexisting luminaires. On average, a 280-watt reduction per fixture will cut electricity use by 580,000 kWhs per year, resulting in approximately $70,000 in energy 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,” says Steve Briggs, VP 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.”
Inside, GE retrofitted approximately 1,250 fixtures, providing a total energy savings of 180,000 kWhs per year. 7-watt PAR20 LED lamps were installed in the hallways, replacing the dated 65-watt incandescent bulbs and saving nearly 150,000 kWhs per year. 20-watt PAR38 lamps were used in the foyer, where high ceilings and scaffolding make maintenance and replacement both difficult and expensive. The PAR38 LEDs are rated for a life of 50,000 hours, meaning they won’t have to be replaced for at least 7 years. 12-watt BR30 lamps greatly improved the auditorium, allowing for a fully dimmable system with higher-quality and more uniform light. Recessed 2’x2′ troffers were added to the lower levels, providing clean, bright light and aesthetic appeal as they appear to blend in with the ceiling.
Marriott HQ’s comprehensive LED retrofit project will reduce annual energy consumption by 66%, cutting energy expense by approximately $120,000 per year. This figure includes savings in electricity, maintenance, and labor. The anticipated total payback period for the project is around two years, which is subsidized by utility rebates and EPACT savings.
Major LED retrofitting projects, such as the system at Marriott HQ, are becoming more practical and logical given the notable energy savings and longevity of LED lighting. Rapid advances in LED technology allow for higher quality light at reduced energy consumption, providing clear benefits for almost any application. Expect to see more LED lighting saving energy and reducing costs in businesses and homes around the world as the market for LEDs is expected to grow 30% annually.
