Spectrum Health in Grand Rapids, Mich., is one of Michigan’s largest not-for-profit health systems. The hospital was looking for a way to revamp the parking decks surrounding its facility with three goals in mind: improve security, reduce maintenance costs and save energy.
The project went to GE, using its Evolve LED garage fixtures. Spectrum retrofitted 1.25 million square feet of parking space with 1,500 of the GE fixtures, which feature an advanced low-glare optical system and a unique thermal management system to enhance lifespan and performance. By replacing older 175-watt high-pressure sodium (HPS) fixtures with GE’s 60-watt Evolve LEDs, Spectrum’s goals were met, saving energy and improving lighting for patients and staff.
Spectrum also installed 50-watt GE Lumination LED recessed troffers in the parking deck ceilings in entrance and exit ways, replacing 150-watt high-intensity discharge (HID) fixtures, and retrofitted one of its parking lots with 202-watt GE Evolve LED area light fixtures, replacing the 400-watt HID fixtures that were previously installed.
The LED fixture upgrade is saving the facility nearly $170,000 annually in combined energy and maintenance costs. The hospital will see a 67 percent reduction in energy use, yielding 1.6 million kilowatt hours (kWh) of energy savings each year. The new LED lights will pay for themselves in just three years, GE said.
