A Third UA Residence gets LED Bulbs

UA officials have seen a reduction in billing already this semester after outfitting a third residence hall with LED bulbs in August, said a UA facilities manager.

All interior compact fluorescent lighting was replaced with LED bulbs in Yocum Hall prior to the fall semester, said Jeffery Vinger, director of residential facilities.

The LED lights lifetime is 15 to 18 years, Vinger said.

The first utility bill since Yocum’s renovations were completed shows a reduction in the monthly average electricity usage, but a good comparison can not be made until all the utility bills for the semester have been received in December, Vinger said.

Officials are working to eventually make LED bulbs the standard on the UA campus, Vinger said. Yocum had 379 fixtures replaced with LED bulbs in the interior of the building.

Founders Hall and Hotz Hall were the first two residence halls to have all LED bulbs, and for the past couple of years, housing has replaced any florescent bulbs that burn out with LED bulbs, Vinger said.

“It’s a long process of replacement,” Vinger said. “Our goal is to keep the cost of operations as efficient and low as possible.”

The City of Fayetteville has used all LED lighting strands for the annual Lights of the Ozarks in the square since 2012, said Byron Humphry, Fayetteville Parks & Recreation Maintenance Superintendent. The city started phasing in LED lights for the festival in 2009.

The LED light strands take less energy to manufacture, last longer and make the distribution of power around the outdoor event easier because they need less energy to run, Humphry said.

LED bulbs have a roughly three times the upfront cost, but greater benefits in the long run, Humphry said.

“We still have some strands from 2010, which is practically unheard of for incandescent lights,” Humphry said.

The electricity bills for the festival are roughly 75 percent less than before, Humphry said.

Electricity is measured by the kilowatt hour by electric companies like SWEPCO, the company who provides electricity to the UofA, Vinger said.

The UofA saved 430,646 kilowatt hours in 2014-2015 because of changes that were made, and so far the changes made this year show a trend toward greater savings than last year, Vinger said.

“To me, it is much more sustainable,” Vinger said.
