NASA Headquarters Brightened Up By Cree LED Lights

Cree's CR series of III-nitride based troffers deliver improved light quality with an estimated 52 percent savings in energy costs
The National Aeronautics and Space Administration (NASA) headquarters, a leased facility in Washington, D.C., has been outfitted with energy-saving CR Series LED Troffers by Cree.

The high-performance LED installation is part of a renovation to maximise energy savings of the 600,000 square-foot building. More than 1,300 Cree CR22 architectural LED troffers have been installed, and Piedmont Office Realty Trust, owners of the NASA headquarters building, expects the new fixtures to deliver energy savings of 52 percent over the previously installed T8 fluorescent fixtures. An additional 5,200 Cree CR22 troffers are planned to complete the lighting upgrade.

“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," says Tony Roberts, senior chief engineer supporting Piedmont Office Realty Trust. “No other manufacturer offered the combination of performance, pricing and efficacy we desired. We continue to be impressed by the improved lighting quality and significant savings the CR22 troffers provide."

Featuring Cree TrueWhite Technology, Cree linear luminaires enabled Piedmont Office Realty Trust to reduce the fixture count by 10 percent, adding to the overall savings. Designed to last for more than 50,000 hours, twice the lifetime of comparable linear fluorescents, the new fixtures are designed to reduce maintenance and operational costs for the headquarters.

The CR22 troffers feature integrated Lutron EcoSystem dimming technology. The system is controlled by a Lutron Quantum lighting control system, which provides the flexibility needed to reconfigure and improve the occupant experience in any space and can extend LED lifetime.

The ability to fine-tune light levels individually in each fixture, and ultimately to achieve the perfect lighting environment, is the result of an ideal marriage between the Cree luminaires and Lutron digital control technology.

“The CR Series is a no-compromise alternative to fluorescent lighting and demonstrates our commitment to driving the broad adoption of LED lighting," says Mike Bauer, vice president of lighting sales, Cree.

“The successful integration of CR troffers with digital controls and dimming allows Cree to further the obsolescence of antiquated fluorescent lighting. Optimal lighting is essential to workplace environments like NASA’s headquarters. Cree linear luminaires deliver unrivalled performance, making the decision to choose LED lighting over fluorescent options an obvious choice."





AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
