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 […]
Lighting Controls Association Announces Results of User Satisfaction Survey
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 […]
New Ballast Energy Standards to Take Effect November 2014
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 […]
Defining Lighting Quality Based On User Satisfaction
Lighting quality is a critical consideration in effective lighting design, and often should take priority over energy savings and the economies of cost. But what is lighting quality? It goes beyond energy and cost and light levels to include brightness, light distribution, color, aesthetics, daylight, ease of use for controls, and other issues. While many […]
What’s New in HID Lamps and Ballasts
Similar trends as fluorescent are driving innovation in high-intensity lighting, which is dominated by HID lighting. Within this segment, there has been a major technology shift from mercury vapor to metal halide over the past 10 years, and the market is trending in favor of white light. Innovation has focused on energy efficiency, longer life […]
LBNL Estimates Average Energy Savings for Popular Lighting Control Strategies
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 […]
