Arizona State University (ASU) retrofitted six parking structures on the Tempe campus with new light-emitting diode (LED) fixtures. Changing the existing fixtures to LED low-bay solution will give ASU an annual savings of up to $127,000 in energy and maintenance costs for the six structures that were retrofit.

As part of a Phase II energy conservation and sustainability project underway throughout the campus, ASU replaced more than 2,000, 150-watt metal halide fixtures. By replacing existing metal halide fixtures and lamps, ASU will reduce its energy consumption by 1.5 million kilowatt-hours.

“Exploring the value of LED lighting solutions is an important component to greening our university,” said Bonny Bentzin, the director of sustainable business practices at ASU. “In addition to the superior level of illumination offered by the LED fixtures, installing energy-efficient lighting provides financial and environmental benefits.”
