A federal government parking deck will have a brighter and more energy-efficient future, thanks to efforts by Philips Wide-Lite and two federal agencies to implement DOE's first Washington, D.C.-based GATEWAY demonstration project. The U.S. Department of Energy, the Labor Department, and Philips have partnered to install Philips' award-winning VizorLED luminaire - an innovative parking, lowbay and under canopy lighting solution - in a parking structure below the Department of Labor's Frances Perkins building, an ENERGY STAR facility.

Replacing existing 100 watt high-pressure sodium (HPS) lamps, the VizorLED units have a rated life of nearly seven years, with a potential life of nearly 18 years thanks to superior thermal management. The VizorLED units are also expected to consume half of the energy of the system they replace. Using VizorLED, the total watts of the parking structure's test area decreased by 50 percent, from 2565W with a Lighting Power Density (LPD) of 0.154 (100HPS) to 1292W with a LPD of 0.077.

In addition, the VizorLED units incorporate Proximo occupancy detectors which dim the luminaires when the space is unoccupied for additional energy savings. Preliminary measurements by the Department of Energy (DOE) have shown an additional 25 percent in energy savings with the use of Proximo for a total reduction in energy usage of 75 percent.

"At Philips we enhance life with light by delivering LED solutions like VizorLED that address the demand for energy efficiency and attractive lighting," said John Campsmith, General Manager, Philips Wide-Lite. "We are honored that this inter-agency partnership showcases our innovative solid-state lighting solutions and the significant impact they have on sustainability."

"The DOE-DOL demonstration shows us in very real terms how LED lighting can make a significant impact on not only our federal energy consumption, but also our nation's energy use," stated Roland Risser, Building Technologies Program Manager at DOE. "Federal agencies must lead by example, and DOE will continue to guide government-industry collaborations to implement high-performance LED products in appropriate applications."

Philips' VizorLED luminaire was named 'Best in Class' in the 'Next Generation Luminaires' (NGL) competition sponsored by the U.S. Department of Energy, the Illuminating Engineering Society of North America (IESNA), and the International Association of Lighting Designers (IALD). Developed by Philips Wide-Lite and using LEDs from Philips Lumileds, the new VizorLED is raising expectations for what is possible with LED-based solutions. It minimizes glare, improves volumetric lighting uniformity, maximizes efficiency and creates an inviting and comfortable environment for people to park and walk through. The VizorLED luminaires easily work with Proximo, an occupancy detector designed to dim lighting to as low as ten percent when the space is unoccupied, allowing for additional significant energy savings.
