Lighting accounts for about a third of electrical energy consumption in commercial buildings. As advanced energy-saving lighting controls still have a minority penetration in the existing building stock, building owners have a major opportunity to reduce energy costs with lighting control. Adoption of advanced lighting controls faces the usual hurdles affecting all energy-efficient lighting, including […]
Lighting Control Rebates Triple Since 2009
Utility and regional energy efficiency organization rebates and incentives have been a major driver in demand for energy-efficient lighting and controls since the early 1990s. Today, more than $6 billion in commercial lighting rebates and other incentives are offered by utilities and energy efficiency organizations covering some 80% of the United States. Currently, rebates and […]
IECC 2012 Decoded
The International Energy Conservation Code (IECC) is a model residential and commercial building energy code produced by the International Code Council. First published in 1998, the IECC was updated in 2000, 2003, 2006, 2009 and, earlier this year, 2012. The IECC is actually not a code, but instead a template for legal jurisdictions to use […]
Bilevel Stairwell Lighting Promises Up to 70-80 Percent Energy Savings
Stairwells account for about 2% of multistory commercial building floorspace, with an average of one light fixture for each 58 sq.ft. of stairwell, according to the International Facility Management Association. It is trafficked 3-5% of the average day. This application has emerged as a strong potential opportunity for energy-saving controls. In the near future, in […]

Encelium Publishes Whitepaper on How Addressable Dimming Controls Can Help Projects Earn LEED Points
Implementation of a proper control system for lighting can be critical for a building to earn LEED certification, as energy performance is the largest driver of the points needed to qualify. It is also important to note that more accurate monitoring and control of energy-intensive systems like HVAC and lighting help keep energy costs in […]
2012 Nonresidential Construction Outlook: A Modest Recovery
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 […]
Lighting Research Center Investigates Dimming Behavior of LED Replacement Lamps
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 […]
Guest Post on LED Product Dimming
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 […]
Department of Energy Names ASHRAE 90.1-2010 as New National Energy Standard
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 […]
