Construction of nearly 2,700 parking spaces at six new or expanded park and ride facilities along the Highway 77/Cedar Avenue and I-35W corridors north and south of downtown Minneapolis was completed in the fall of 2010. MetroTransit installed Cree® luminaires in park and ride ramps located in Lakeville, Roseville, Blaine and Cedar Grove. Each architecturally-unique structure has more than 600 parking garage luminaires illuminating interior, perimeter and surface parking spaces.
Bonestroo Inc. provided engineering design services for the Lakeville and Roseville parking structures. LED luminaires were selected for the value that energy efficient lighting products provide and the importance of using a sustainable light source.
“We analyzed pulse start metal halide, compact fluorescent and T5HO solutions and while they had a lower capital cost, everyone saw the value of energy and maintenance savings that LED provides. We took advantage of the photocell option that maximizes energy savings by allowing each fixture to turn off if the natural ambient lighting is high enough,” explained Mike FitzPatrick, PE, LEED AP associate for Bonestroo. “This is a better solution than the standard zone-controlled systems used on other projects. The LED fixtures allow us to do this because of the instant-on startup as compared to pulse start metal halide fixtures.”
