Denver International Airport is retrofitting more than 5,400 lights located in the airport’s east and west parking garages with energy-efficient LED fixtures, resulting in substantial energy and cost savings.
The majority of the lights—high-pressure sodium bulbs rated for 188 watts per fixture—are being replaced with 51-watt LEDs. Combined with other lighting systems in the overall retrofit package, DIA expects a net energy savings of about 45%, resulting in energy cost savings of about $327,000 per year.
