Just as the US Department of Energy (DOE) recognized ANSI/ASHRAE/IESNA Standard 90.1-2010 as the national energy standard, WattStopper launched a new CodeSmart publication designed to guide lighting and building professionals through the intricacies of the many lighting control requirements that debuted in this newest version of the code. The informative booklet available for free download […]
Although the national economic recovery is now two and a half years old, construction spending has continued to contract. A multitude of factors prevented a recovery for this beleaguered industry in 2011. Lenders that have been extremely reticent to finance construction projects, budget shortfalls at all levels of government, the ripple effect of overbuilding, depletion […]
Designing LED replacement lamps that are compatible with residential dimmers is complex given the diversity in product performance, creating a challenge for manufacturers to design lamps compatibel with a wide range of dimmers. On behalf of ASSIST, the Lighting Research Center investigated dimming performance of a range of LED replacement lamps, CFLs and incandescent lamps […]
The National Electrical Manufacturers Association (NEMA) has published NEMA LSD 56 Compatibility of Forward Phase Control Dimmers and Dimmable Self-Ballasted Compact Fluorescent Lamps and Frequently Asked Questions Regarding CFLs and Dimming, available for free download. This publication provides design guidance in the area of lamp/dimmer compatibility to the manufacturers of dimmable self-ballasted compact fluorescent lamps […]
by Jim Brodrick, Department of Energy As more and more LED lighting products have come onto the market, one issue that has generated considerable confusion is dimmability. As discrete devices, LEDs are fully dimmable, and as a result the technology has long been touted as being more suitable for dimming than other lighting technologies. Many […]
In July 2011, the Department of Energy recognized the ASHRAE/IES 90.1-2007 standard as the new national energy standard, superseding the 2004 version. In a bold move, on October 19, 2011, DOE recognized the 2010 version of 90.1 as the new national energy standard. By October 18, 2013, all states in the United States must put […]
The Lighting Controls Association is pleased to announce that it has updated EE103: Dimming Control, a popular offering in the Association’s Education Express series of online distance education courses about lighting controls. The course, authored by Craig DiLouie, principal of ZING Communications, Inc. and LCA’s Education Director, provides an in-depth discussion of dimming technology and […]
Consulting-Specifying Engineer has published an article by Brian Baumgartle, PE, LC, LEED AP of CMTA Inc. about lighting and control changes in the ASHRAE/IES 90.1-2010 energy standard, recently recognized by the Department of Energy as the national energy standard effective October 2013. Check it out here.
Last month at LightingControlsAssociation.org, we published an article about how to establish daylight zones in sidelighted (windowed) building spaces. We looked at an industry rule of thumb and then how the latest generation of energy codes and standards address it. In review, when designing an energy-saving daylight harvesting control system, a critical decision is to […]
