LED technology is one of the highest performing, currently available methods of lighting. This project reflects our high regard for the planet, but it also ensures that MGM Grand Detroit is meeting our customers’ desire to be more environmentally conscious with their meetings, conventions, and travel.” “Like many of our conservation initiatives, this renovation is a win-win for us and the environment. “As a property fully committed to the fundamental principles of environmental stewardship, we are proud to complete the LED lamp installation and further minimize MGM Grand Detroit’s energy consumption,” said Steve Zanella, President and COO of MGM Grand Detroit. Cited as one of the nation’s largest LED parking garage makeovers, the three-month installation boasts 3,117 LED lamps and will reduce the garage’s annual energy use by 80 percent at the Four Diamond destination resort. Further demonstrating its leadership in environmental sustainability, MGM Grand Detroit has completed the light-emitting diode (LED) lamp retrofit of its 61-acre parking garage.
