As a manufacturers rep agency covering Tennessee, Arkansas, and Northern Mississippi, John Moore & Associates (JMA) had been singing the praises of DEMANDflex™ ballasts and DCL® control systems since they were first introduced to the market in 2008. And yet, the company was still using 400-watt metal halide ballasts at its 100,000 sq. ft. warehouse just outside of Nashville. Finally, in August 2010, they decided it was time to stop wasting money and start practicing what they were preaching.
Encelium Technologies offers an innovative office lighting control system to drive substantial lighting energy savings in office buildings. Encelium’s Energy Control System™ (ECS) has been proven to secure lighting energy savings of 50% to 75% in office applications.
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.
