Dr. Ian Rowbottom of Lutron Electronics authored a whitepaper on the Lutron website titled, “Building Dimmers Vs. Building Power Plants.” Using simple math, he makes a case that while it costs $1.40-$7.75 to build a watt of electric generating capacity, it costs only about $0.35 to remove a watt with a dimmer. He writes, “At […]
IMS Research projects that the market for lighting control devices in commercial buildings will double from 2010 to 2017, with shipments of devices increasing from 29.6 million to 61.6 million. Most of these components will be connected ballasts that contain a connectivity technology such as DALI or ZigBee, says the research organization. One of the […]
Despite a national recovery from the recession in 2009, construction activity in the United States continued to spiral downward in following years. Total construction spending declined to under $800 billion in 2011 from its peak of more than $1 trillion in 2008. In 2012, the market turned a corner and achieved a level of growth […]
Guest post by Jim Brodrick, U.S. Department of Energy There’s a great deal of interest these days in occupancy sensors as a way to save energy in outdoor commercial lighting applications. Done right, they can increase the energy savings from a lighting system that’s already efficient – such as one based on LEDs, whose inherent […]
ECO-STRUCTURE has published an article by industry educator Craig DiLouie, LC on the topic of daylight harvesting. Read it here.
The Energy Policy Act of 2005 created the Energy-Efficient Commercial Buildings Tax Deduction (CBTD) to encourage owner investment in energy-efficient building systems. The CBTD establishes a special tax deduction rewarding investment in energy-efficient interior lighting, HVAC/hot water systems and building envelope, subject to a cap of up to $1.80/sq.ft. It’s an accelerated tax deduction, meaning […]
In an ideal world, clients state clear project requirements. The design team unites around a concept. The design documents clearly express the design intent. The contractor installs and starts the system without errors. And users benefit from quality lighting and control. In reality, any number of things can go wrong. The client may have unclear […]
EC&M has published an article about trends in lighting control, noting occupancy-based shutoff and daylight harvesting and then focusing on LED control, including wireless options. Read it here.
The Lighting Controls Association has announced the results of a recent survey of regular site users. The purpose of the survey, which was distributed to 15,000 subscribers of the LCA newsletter lightingCONTROL, was to determine satisfaction with the LCA website as well as the popularity of potential features. Respondents totaled 241, or 1.6%. The first […]
In November 2011, the Department of Energy (DOE) issued new rules regulating the efficiency of fluorescent lamp ballasts, which take effect November 14, 2014. The rulemaking creates a new metric for measuring ballast efficiency and establishes a higher standard of efficiency that will impact many of today’s fluorescent T8, T5 and T12 ballasts. Ballasts that […]
