Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy As we mentioned in these Postings a few weeks ago, the biggest takeaway from this year’s LIGHTFAIR® International was the prevalence of connected products, and the fact that sensors and controls seemed […]
enLIGHTenment Magazine recently published an article about the growth of smart lighting for the home, and what it may mean both for consumers and the controls industry. From the article: With the LED revolution has come another shift: lighting products and controls used to be separate entities, but now they are being combined into one […]
Michael Siminovitch of the CLTC was recently interviewed for the Echelon blog about adaptive lighting. He says: “We asked, could we dynamically address the lighting according to need, and to do it in a way that preserves safety and security and aesthetics? This isn’t just about turning off the lights. It’s the idea of reducing […]
Municipalities can benefit from reduced energy and more efficient management of street lights through GE’s new LightGrid™ Outdoor Wireless Control System. With the technology of GE Lighting’s central management software, the LightGrid Outdoor Wireless Control System can report energy usage and other operational data of street lights to a central database. A Web-based interface linked […]
In September 2012, the Lawrence Berkeley National Laboratory published, Responsive Lighting Solutions for the General Services Administration (GSA). The report provides insight into the viability of highly responsive lighting control systems. It reports the results of installing advanced lighting controls in five Federal buildings. The existing lighting in these buildings was upgraded. A number of […]
Terry Mocherniak, Chief Operating Officer for Encelium Technologies, contributed an article to AutomatedBuildings.com about addressable lighting controls and specifically Encelium’s Energy Control System™. Check it out here.
Control wiring provides a path for command and status communication between control devices in a lighting and control system and, in many cases, power to the devices as well. Wiring is interrelated with overall lighting control system considerations—such as selection of control system and components, layout and installation practices—and is therefore an important consideration when choosing a lighting control solution.
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.
What are the benefits of combining advanced lighting control strategies in the same space? Are the energy-saving benefits of lighting controls persistent over time? Can advanced lighting controls be successfully applied to open offices given concerns about jurisdiction conflicts, lighting uniformity, etc.? Can they enhance worker satisfaction? A new office lighting field study addresses these questions. Involving about 90 workers in a real-world open-office environment, the one-year study determined that occupancy sensing, daylight harvesting and individual occupant dimming control worked together in the building to produce average energy savings of 47% while correlating with higher occupant environmental and job satisfaction. The study demonstrates that sophisticated lighting control strategies can be combined successfully to generate persistent, large energy savings in open-plan offices while improving occupant satisfaction with their jobs and workspace.
Dimming of fluorescent lighting offers significant benefits in terms of supporting visual needs with good lighting, giving users control of their own lighting, and energy savings. The advent of digital dimming offers a new option with clear advantages over traditional analog dimming. Digital dimming can be used almost anywhere that analog dimming can be used, for the same purposes: visual needs, personal control, daylight harvesting, scheduling and other control strategies. If fluorescent dimming is desirable for a given application, digital dimming can offer distinct advantages related to intelligence, flexibility and two-way communication.
