The energy service company (ESCO) market for energy efficiency project installations and services exceeded $5.1 billion in 2011, according to a new report by Pike Research. This market is expected to continue to grow faster than the domestic economy and reach $16 billion in sales by 2020. This Pike Research report describes the continuing evolution [...]

Evaluation methods and testing requirements for LED and solid-state lighting products are rapidly changing as new standards, metrics, and labeling programs become available to the lighting industry. As a result, the Lighting Research Center (LRC) has developed a new professional lighting seminar, the Photometry Institute, to be held April 11-12, 2012. In this two-day, interactive [...]

The National Electrical Manufacturers Association (NEMA) has published ANSI ANSLG C78.21—Incandescent lamps: PAR and R Shapes and ANSI ANSLG C78.40—Electric Lamps: Specifications for Mercury Lamps. Providing physical and electrical characteristics of incandescent lamps, ANSI/ANSLG C78.21-2011 describes PAR and R bulb shapes. The standard covers lamps with clear, frosted and lens end bulbs, clear and prescription [...]

Tru Start by TCP is a new generation of compact fluorescent lamps featuring a 15- to 20-second run-up time, 20,000-hour rated life and good light output.

According to a new report from Pike Research, worldwide revenue from zero energy buildings will grow rapidly over the next two decades, reaching almost $690 billion by 2020 and nearly $1.3 trillion by 2035. That represents a compound annual growth rate of 43%, with much of that growth occurring in the European Union. Pike Research’s [...]

The 2011 National Energy Code of Canada for Buildings (NECB) provides minimum requirements for the design and construction of energy-efficient buildings and covers the building envelope, systems and equipment for heating, ventilating and air-conditioning, service water heating, lighting, and the provision of electrical power systems and motors. Check it out here.

Construction spending during December 2011 was estimated at a seasonally adjusted annual rate of $816.4 billion, 1.5% (±1.4%) above the revised November estimate of $804 billion, according to the Department of Commerce. The December figure is 4.3% (±1.9%) above the December 2010 estimate of $782.9 billion. The value of construction in 2011 was $787.4 billion, [...]

Common household lamps now carry uniform labeling to facilitate educated decisions focusing on light output and energy costs, not watts, helping consumers transition to more efficient lamp types. That’s the topic of an article I contributed to the January 2012 issue of Electrical Contractor Magazine. Read it here.
