DOE Gateway report documents LED lighting performance

The US Department of Energy has released another report in its Gateway series covering real-world installations of solid-state lighting (SSL) technology in general-lighting applications — in this case focused on four very different indoor applications. The projects span new construction to large-scale retrofits and involved the Hilton Hotel in downtown Columbus, OH; St. Anthony Hospital in Gig Harbor, WA; the Carl Icahn Laboratory at Princeton University in Princeton, NJ; and the University of Maryland’s Clarice Smith Performing Arts Center (CSPAC) in College Park, MD. The long-term study does reveal energy savings, but the DOE concluded that the projects illustrate other reasons ranging from maintenance savings to controls to improved light quality that justify the installation of LED-based lighting.
