DURHAM, N.C. — The National Aeronautics and Space Administration headquarters, a leased facility in Washington, D.C., is being outfitted with LED lighting fixtures made by Cree.
The LED installation is part of a renovation to maximize energy savings of the 600,000-square-foot building. More than 1,300 Cree CR22 architectural LED troffers, or fixtures, have been installed. An additional 5,200 Cree troffers are planned to complete the lighting upgrade.
Piedmont Office Realty Trust, owners of the NASA headquarters building, expects the new fixtures to deliver energy savings of 52 percent more than the previously installed T8 fluorescent fixtures.
Cree, which includes what was formerly Ruud Lighting before Cree’s acquisition, has a large manufacturing operation at 9201 Washington Ave. The fixtures are assembled there.
“We originally considered replacing the existing T8 fluorescent tubes with T5 fluorescents, but after testing Cree’s CR22 LED troffer, we knew it was the best solution for this installation,” Tony Roberts, senior chief engineer supporting Piedmont, stated in a news release. “No other manufacturer offered the combination of performance, pricing and efficacy we desired.”
Cree said its luminaires enabled Piedmont to reduce the fixture count by 10 percent which will add to the overall savings.
Because they are designed to last for more than 50,000 hours, twice the lifetime of comparable linear fluorescents, the new fixtures will reduce maintenance and operational costs for the headquarters, Cree said.
“The successful integration of CR troffers with digital controls and dimming allows Cree to further the obsolescence of antiquated fluorescent lighting,” stated Mike Bauer, vice president of lighting sales for Cree. “Optimal lighting is essential to workplace environments like NASA’s headquarters.”
According to the U.S. Green Building Council, the federal government is the single-largest user of energy in the United States, using about 1.5 percent of the total U.S. energy consumption. The Council says the federal government either owns, operates or leases about 500,000 buildings, many of them “aging and in dire need of energy and other efficiency upgrades.”
