Bilevel switching, in which alternate rows, fixtures or lamps are separately circuited and independently controlled, has been demonstrated in one study to produce 22 percent energy savings in private offices.
The U.S. Department of Energy (DOE) predicts that solid-state lighting will achieve efficacies as high as 160 lumens per watt and provide most of our general lighting needs within the next 20 years, thereby reducing the nation’s energy costs by 6–7 percent.
Between 1984 and 2003, the percentage of people directly using a computer at work more than doubled to nearly 57 percent. The widespread adoption of computers not only changed office environments but also best practices in lighting and, by extension, office lighting technology.
Proving that city landmarks and structures don’t need to go dark to be energy conscious, the Peace Bridge in Buffalo, N.Y./Fort Erie, Ontario, has undergone an energy-conscious transformation made possible by light-emitting diode (LED) technology.
In Turner Construction's 2008 Green Building Market Barometer survey of 754 commercial real estate executives, a significant percentage of respondents view green buildings as having lower operating costs and higher building values, rent requirements, occupancy rates and overall return on investment
The National Electrical Manufacturers Association (NEMA) has released market research results that illuminate America’s need for information about energy and cost saving through modern lighting systems.
The International Code Council (ICC) develops model codes regulating construction of residential and commercial buildings, one of which is the International Energy Conservation Code (IECC). Most states have a commercial or residential energy code that is based on some version of the IECC.
While the dominant theme at ISC West was going digital and networking, the 2009 Lightfair International was all about going green—how smart use of lighting can make big reductions in energy consumption.
Results of a recent study conducted by the University of Minnesota School of Public Health, Division of Environmental Health Sciences, suggest that most containers used for storage and transportation of used fluorescent lamps to recycling centers do not provide necessary levels of protection against
Lighting control manufacturer Lutron Electronics opened its Experience Showroom in the heart of midtown Manhattan. The new, 1,800 square-foot Experience Showroom is located on the ground floor of the Decoration & Design (D&D) Building.
After the Energy Independence and Security Act became law in late 2007, threatening an end to 40–100 watt general-service incandescent lamps, a consumer backlash began building against compact fluorescent lamps (CFLs).
The Ameren Illinios utilities announced the successful completion of Act On Energy, a pilot high-efficiency lighting project that sharply cut energy consumption in the frozen-food reach-in cases and refrigerated dairy and beverage cases at a Kroger store in Peoria, Ill.
The stakes are high. According to U.S. Department of Energy (DOE) estimates, nearly 1 billion 60W A19 lamps will be installed in the United States by 2010. America is calling for a super-efficient lamp and has pinned its hopes on solid-state lighting.
In recent years, ballast manufacturers have begun marketing a premium fluorescent ballast called a “high-efficiency ballast” for operation of 4-foot T8 lamps. A high-efficiency ballast provides the same level of light output as a standard electronic ballast but does it with 2-–5 fewer watts.
The Energy Policy Act of 2005 created the Commercial Buildings Deduction (CBD), an incentive consisting of an accelerated tax deduction rewarding investment in energy-efficient interior lighting; heating, ventilating and air conditioning/hot water systems; and building envelope.
Internet protocol (IP), the hottest trend in integrated building systems, is attracting interest because any computer with an Internet connection can talk to any building system that runs a digital addressable IP network.
