Fluorescent ballast regulations have essentially eliminated the magnetic T12 ballast with few exceptions, including F40T12, F96T12 and F96T12HO ballasts for both full-wattage and energy-saving versions of these lamps. Two years later, in 2012, additional regulations will take effect, creating new energy standards for selected linear T5, T8 and T12 lamps. The net result is a majority of 4-ft. linear and 2-ft. U-shaped T12, many 8-ft. T12 and T12HO, and some low-color-rendering 4-ft. T8 lamps will be eliminated. Based on these facts, one could make a simple argument that it is now time to upgrade existing lighting and control systems to improve energy efficiency and lighting quality.
This month, Federal efficiency standards regulating fluorescent magnetic T12 ballasts entered their final phase, effectively eliminating these ballasts from the market, with few exceptions.
The U.S. Department of Energy (DOE) has unveiled the Commercial Lighting Solutions for Office webtool. Available free at www.lightingsolutions.energy.gov, CLS for Office provides customizable lighting and control templates enabling building owners to generate more than 30% lighting energy savings compared to office buildings complying with prevailing energy codes.
Liberty Property Trust partnered with Encelium Technologies to reduce overall lighting energy consumption by 60 percent. The real estate investment trust, which owns 77 million square feet of office and industrial space in more than 20 markets throughout the United States and the United Kingdom, used its 31,000-square-foot office building as a pilot demonstration site of Encelium’s highly advanced Energy Control System (ECS) for use in its other properties.
Kaiser Permanente installed WattStopper lighting controls as part of a warehouse renovation designed to improve lighting and reduced energy consumption. The upgrade resulted in better task lighting throughout the facility and energy savings of over 40%, as detailed in the following case study.
Researchers at the National Research Council Canada – Institute for Research in Construction (NRC-IRC) conducted a study to determine how far, how fast and over what period lighting can be dimmed before occupants notice and are adversely affected. The results suggest a role for dimmable lighting in demand response programs.
WearGuard-Crest, a division of ARAMARK, set an ambitious goal: to replace all the lighting fixtures throughout 280,000 square feet of office, manufacturing, and retail space at its headquarters in Norwell, Massachusetts, just south of Boston. Furthermore, the company wanted the project to pay for itself in energy savings. J&R Wiring, Inc., took up the challenge. After researching the most advanced lighting control systems on the market today, J&R Wiring identified the one technology with the most powerful return on investment (ROI)—DCL® (Demand Control Lighting) from Universal Lighting Technologies.
Convincing a public school system to retrofit the lighting in a high school gymnasium that was constructed only two years ago is not an easy task. But the energy-saving advantages offered by DCL® Control Systems earned a “yes” from the Silver Lake Regional School District in Kingston, Mass.
Bank of America Plaza is one of the most prestigious office properties in Los Angeles. Completed in 1974, it was the first high-rise structure to tower over the downtown cityscape. Today, it is a model of energy efficiency, featuring cutting-edge technologies that minimize power consumption and utility bills. Brookfield Properties has significantly invested in Bank of America Plaza modernization over the past three years. Brookfield had plans to upgrade the lighting equipment in the skyscraper’s parking garage and was exploring options when California Retrofit, Inc. (CRI), introduced them to the latest breakthrough in ballast technology. Unveiled in 2008 by Universal Lighting Technologies, DEMANDflex™ ballasts feature an adjustable ballast factor so that installers can “tune” ballasts to the exact power level required for the customer environment. Using a temporary tuning tool, the installer sets a maximum power level for each circuit of ballasts, which can be as low as 50 percent of full power. This eliminates the common problem of over lighting an area and wasting energy.
Glenn D. Hughes, president of Glenn D. Hughes Consulting Associates and the director of construction for The New York Times Company during the design, installation, and commissioning of the new 52-story New York Times Building, last year made news with his announcement that the Quantum total light management system in the building was achieving a 70 percent lighting energy savings.
