Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy The U.S. Department of Energy (DOE) recently released a GATEWAY report on a parking-garage demonstration conducted at U.S. Department of Labor (DOL) headquarters in Washington, DC, which serves as a classic illustration of the savings […]
A survey conducted by manufacturer Precision-Paragon found respondents reporting they include some type of automatic lighting control in 48% of their lighting retrofit projects. Greentech has the story here.
BD+C University offers 1.0 AIA LU/HSW for registering and reading an article about advanced lighting and control solutions. From BD+C: After reading this article, you should be able to: * Describe the challenges for delivering sustainable, efficient lighting design in commercial projects, enhancing occupant well-being and saving resources. * Discuss illumination technologies available to project […]
In a recent study, the Energy Center of Wisconsin monitored several daylighting systems in Minnesota and Wisconsin and analyzed the results of commissioning those systems. The researchers concluded: “Energy modeling, with its assumption of ideal control, appears to have the potential of being an accurate predictive tool for highly effective (>75%) control systems. However, the […]
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 […]
Intelligent, controllable LED lamps offer a new paradigm for home lighting control. Julie Jacobson, editor of ELECTRONIC HOUSE, analyzes the pros and cons of 13 products implementing WiFi/Internet of Things, 6LoWPAN, ZigBee, Z-Wave and Bluetooth. Read it here.
Daylight harvesting control, or the practice of using light sensors to automatically reduce electric light in a space when sufficient daylight is present, has been demonstrated to produce significant energy cost savings in buildings. As a proven energy-saving strategy, it has been implemented into many sustainable building projects. It was also incorporated into ASHRAE/IES 90.1-2010 […]
Version 4 of the popular Leadership in Energy & Environmental Design (LEED) green building rating system is expected to be released at Greenbuild in November 2013. Final balloting to approve the new LEED version is expected to occur in June, so we don’t know exactly what will be contained in the new rating system. One […]
Schneider Electric offers a free whitepaper addressing measurement and verification of lighting systems. Measurement and verification (M&V) defines a process used to track energy performance of equipment, systems and buildings, enabling evaluation and comparison. M&V plans have become an essential element in many LEED Projects as well as many public projects. The whitepaper, authored by […]
ELECTRICAL CONTRACTOR has published an article by Craig DiLouie describing how to zone lighting control strategies and develop a control zone plan. Check it out here.
