ASU is embracing projects to use renewable energy resources one parking structure at a time.
The ASU Capital Programs Management Group designed and built a solar panel system now placed on Parking Structure 2, at McAllister Avenue and Terrace Road, to sustain power for the structure. It also provides covered parking for 44 spaces, just fewer than half the spots on the top level of the structure.
Construction was completed and energy generation began in February.
The structure has two steel carport canopies that attach to the structure walls. The top of it is made of laminate solar panels.
Parking Structure 2 was chosen based on its small electrical needs compared to other structures.
"We designed it to limit the electrical power just for the parking structure," said Ray Tena, project manager for the solar project.
Parking structures use power for lights, gate arms and elevators.
This project saves 47,770 kilowatts per hour and about $16,900 annually.
The project originally cost nearly $500,000, but a $140,000 rebate from Arizona Public Service cut the cost to $360,000.
It will take about 10 years to pay back the initial cost of the project.
Tena said he researched solar energy for about two years before creating this project in September.
"It is important for ASU to look at opportunities for sustainability, especially in energy efficiency and renewable resources," Tena said.
"Anything to preserve the environment should be weighed stronger than anything that takes away from it," said Tom Winterbottom, a communication freshman.
The Governor's Energy Office gave ASU an award of merit for the project in early April.
"The reaction to our solar project has been positive," Tena said. "This award recognizes energy efficiency.
"The next step is to look at all the parking structures on campus and proceed with the ones with the fastest payback on the project investment," Tena said.
Parking Structure 7 may be next because it already has a canopy system, which would reduce initial cost.
Courtney Tinnan, a first-year English master's student who parks in Parking Structure 7, liked the idea of project expansion.
"If it works the first time, I don't see why not," she said.
