Founded in 1869, the main campus of Purdue University in West Lafayette, Indiana, is home to approximately 39,000 students. The statewide university system includes five campuses, numerous teaching and research sites, and a system-wide enrollment of approximately 69,000 students. For 30 years, Purdue University has provided its instructors with the ability to dim the lighting in their classrooms.
For years, Lander University relied on a programmable relay-based system installed in the mid 1980s to provide energy-saving scheduled control of lighting and equipment for its most vital buildings. While the system, which controlled the Learning Center, Cultural Center, Student Center and Athletic Complex, had initially served its purpose, the controls had become antiquated and unreliable. After experiencing numerous disruptions to classes and events, engineers at the state university in Greenwood, S.C., set out to research replacement options.
Engineering Services Department personnel priced equipment and installation costs for a variety of solutions and were delighted to learn about Watt Stopper/Legrand’s unique ability to upgrade older GE panels, retrofitting them with new control engines. For less than ten percent of the cost of a new system, they could refurbish the existing panels and enjoy the benefits of a sophisticated, modern control system. The university could significantly extend the life of its capital equipment and avoid sending materials to a landfill. Additionally, the upgrade would take much less time than a full replacement.
Square D® Clipsal® lighting control products from Schneider Electric were key components in a retrofit project at Fay Herron Elementary School near Las Vegas, Nev., that was honored as a Best of 2007 project by Southwest Contractor magazine. The award program, which honored the Fay Herron Elementary School Rehabilitation and Modernization project as winner of the Mechanical/Electrical category, recognizes construction and design excellence in Nevada, Arizona and New Mexico. The project was one of 218 entries submitted from Nevada, among more than 700 total entries from the tri-state area.
As part of its mission to promote energy efficiency and innovation for the benefit of its customers, the New York Power Authority (NYPA) gives special emphasis to demonstrating new energy-saving technologies. Along these lines, NYPA installed AddressPro® Digital Dimming—an advanced lighting-control technology—from Universal Lighting in several areas of its main administrative office building in White Plains. This was done as part of the wide-ranging measures NYPA has undertaken in recent years to augment the seventeen-story building’s energy efficiency for lowering electric bills and reducing carbon emissions.
In October 2005, Wal-Mart CEO Lee Scott outlined an ambitious vision for the future operations of the company focusing on becoming a good steward of the environment and local communities. He announced that the company’s long term environmental goals are: 1. To be supplied 100 percent by renewable energy; 2. To create zero waste; and 3. To sell products that sustain our resources and environment. Short term goals included eliminating 30 percent of the energy used by stores.
Since then, Wal-Mart engineers have worked diligently to identify areas for potential energy savings. They have collaborated with suppliers to innovate solutions, tested new technologies and finalized proven designs to implement in corporate facilities.
One store system designated for an efficiency upgrade was the fluorescent lighting in refrigerated food cases, which burns 24 hours a day. Recently, LED lighting coupled with occupancy sensing controls was proven to provide the combination of energy savings, improved performance and reduced maintenance to justify incorporating a new design for refrigerator and freezer case lighting and controls into plans for all new stores. Because the energy savings are so significant, a program is also underway to retrofit cases in over 450 existing stores in 2007.
Vermont-based manufacturer NRG Systems in 2005 built a new headquarters carefully crafted to reflect the company’s commitment to the environment, the community and its employees. The 46,550 square foot facility, which includes office, manufacturing and warehouse space for company-produced wind monitoring equipment, was designed to minimize environmental impacts and maximize energy conservation.
The first design goal was to find ways to minimize energy needs in all areas of building operation, including heating, cooling and lighting. The second goal was to provide as much energy from renewable sources as possible. Company owners were willing to make an upfront investment to ensure significant long-term savings.
Naomi Miller of Naomi Miller Lighting Design specified the electric lighting and Andy Shapiro of Energy Balance, Inc. developed the facility’s daylighting plan. The two designers collaborated with Watt Stopper/Legrand to select energy saving controls that would meet the ambitious criteria of the project.
Schneider Electric announced that its Square D® Clipsal® line of lighting control products is being incorporated into a major energy retrofit project at Fay Herron Elementary School in North Las Vegas, Nev. The school, part of the Clark County School District, is the subject of a project that includes HVAC replacement and installation of new insulated walls and dropped ceilings, in addition to lighting control. Eight of the 12 buildings on the Fay Herron Elementary School campus have been completed; the entire project should conclude in summer 2007.
Advance introduces its exclusive new Ballast Checker, an easy-to-use hand-held device that quickly identifies a ballast’s technology type for use in confirming ballast status and pinpointing lighting upgrade opportunities.
The University of Toronto’s new “electronic classroom” combines familiar audiovisual equipment, such as slide projectors and VCRs, with such sophisticated equipment as a multi-sync data/video projection system and multi-scene preset dimming controls. Instructors can now electronically enhance their lectures with an integrated user-friendly presentation system.
How do you upgrade the 14-year-old dimming system of a 33,000 sq. foot ballroom that utilizes low voltage wiring? Simple: a retrofit installation utilizing the LYTEmode™ Architectural Lighting Control System.
At the Philadelphia Marriott, in Philadelphia, PA, this was the task at hand that was given to Larry Fine, Senior Architectural Representative for Lightolier®.
