Facilities C AMPUS SPACES Navigating Through New Lighting Choices LED fxtures are replacing other lighting choices for all applications. The technology can't replace everything yet, but the lighting industry is moving that way. BY CHIN LIN, AIA , LEED -AP 24 PHOTO © JACK NEITH I MAGINE THE DAY WHEN YOU don't need to change a light bulb. With a number of manufacturers introducing 100,000-hour LED fi xtures as well as some with a projected life of more than 150,000 hours, replacing light bulbs may soon be a thing of the past. The lighting industry is currently going through a revolution, as new legislation requires light bulbs (or lamps, as the industry calls them) to meet minimum efficiency standards. Advances in light fi xture design and technology have progressed so rapidly that what was unthinkable only a few years ago is now reality. It seems that every three to six months another major advance in lighting technology is announced. Even the popular compact fluorescent lamps (CFLs) are losing favor as LEDs become more affordable. For most of today's lighting designers CFLs are now an outdated technology, and it's a matter of time before LEDs replace them altogether. Light fi xtures have also become so efficient that utilities are providing incentives to retrofit buildings completed as recently as five years ago as a way to reduce energy consumption. Colleges and universities would do well to understand these developments and how to leverage them to their facilities' advantage. Two of the most notable innovations in lighting technology include high-efficiency linear fluorescent fixtures and advancements in LED fixtures. Both lighting options provide high-quality light in an array of lighting designs while consuming IS IT BRIGHT IN HERE? A recent renovation of the O'Callahan Library at the College of the Holy Cross in Worcester, MA, included the installation of the latest in LED solid-state lighting and energy-efficient fluorescent lighting technologies. In addition to resulting spaces that are open and light and that encourage interaction between students and faculty, the College — a signatory of the ACUPCC — has seen substantial energy savings from the new lighting. significantly less energy. Paired with sophisticated control systems behind the scenes, a college or university can reduce its energy consumption and maintenance costs through smart lighting design. High-Efficiency Fluorescent Lighting: Not Your Parents' Light Bulb Through the last few years, highefficiency linear fluorescent fi xtures have been developed by several manufacturers, COLLEGE PLANNING & MANAGEMENT / DECEMBER 2012 achieving 90 to 95 percent efficacy rate with extremely good distribution patterns that allow for more flexibility in layout and design. This technology, along with the advances made in linear fluorescent lamps, may reduce the number of fi xtures required in a given space, as well as reduce the light power density for a building. Using high-efficiency linear fluorescent fi xtures instead of conventional linear fluorescent fi xtures could save up to 30 percent in the total connected wattage WWW.PLANNING 4EDUCATION.COM
