United States. About $120,000 a year will save the Marriott hotel chain on its energy and maintenance costs for the company's corporate headquarters in Maryland, United States.
This will be possible thanks to the renovation of all the lighting systems of the building, which will allow a reduction in consumption of 860 thousand kilowatt hours (Kwhs), while offering employees a better quality of lighting.
The company selected to optimize Marriott's headquarters was General Electric (GE), who after conducting an audit of the existing lighting selected the Evolve product line as the most suitable for the company's needs.
This is how more than 230 LED luminaires were installed for the outdoor lots, and about 400 LED garage lights for the covered parking, in addition to several LED tunnel lights.
According to GE, with the above, a reduction of 280 watts per exterior lamp was achieved, which is reflected in a reduction in electricity consumption of 580 thousand Kwhs per year and US $ 70,000 in monetary savings. In addition to the above, motion detectors were also installed in the garage and the system was integrated with the video surveillance center.
As for the interior of the facilities, the company replaced a thousand 65-watt bulbs with 7-watt LED lamps in the corridors, thus achieving a saving of US $ 18,000. Both the company's auditorium and the ground floor of the building underwent changes in their lighting equipment that complemented the system.
