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.
Cherokee Investment Partners, a private equity fund managing institutional capital to acquire environmentally impacted properties, recently challenged itself to oversee construction of a sustainable residential project that, to prospective owners, would look and feel like a traditional home. The Raleigh, North Carolina project, dubbed the National Homebuilder Mainstream GreenHome, includes energy saving occupancy and vacancy sensors and time switches from Watt Stopper/Legrand throughout the home.
While planning the Palms of Perdido condominium project on beautiful Perdido Key, Florida, developers and resident owners Dick and Teresa Domurat spent several years researching amenities, including lighting controls. They selected Miro wireless RF controls and occupancy sensors from Watt Stopper/Legrand based on ease of installation, simplicity of system expansion and product performance and styling.
A breakthrough light management system from Lutron® Electronics Co., Inc., recently installed in a new, landmark Manhattan office tower, is achieving a “stunning” 70 percent energy savings compared to the ambitious energy-efficiency benchmark the building was designed to meet.
