What will it take?

What will it take?

Standards developed under the umbrella of the International Electrotechnical Commission (IEC) facilitate international trade and enable manufacturers to maintain a single product for world market access.  Many governments adopt IEC standards as their own and may even include them in their regulatory structure to help ensure the safety of their country's populace and property on the basis that compliance with the requirements establishes playing field on which producers must compete Read more [...]
The EV Race is On – Are We Ready? NEMA Responds

The EV Race is On – Are We Ready? NEMA Responds

The Race is on.  Interest is buzzing surrounding the potential future proliferation of Electric Vehicles (EVs). So many questions have day-to-day drivers and other potential consumers of this budding technology wondering: How convenient (or inconvenient) will it be to recharge an EV’s battery?  Will there be a quick charge option in addition to a regular charge with every EV vehicle? Is a quick charge quick enough? Is the range long enough for typical commuting needs? Are Read more [...]
USGBC and challenges to its LEED point High Performance Buildings Rating System

USGBC and challenges to its LEED point High Performance Buildings Rating System

The U.S. Green Building Council (USGBC) has been recently challenged by a third-party to a LEED certification. It involves an appeal of the Gold building certificate awarded to Northland Pines High School in Eagle River, Wis in 2007. The appellants contend the design and construction of the school did not meet a number of prerequisites for the certification.  The appellants claim, among other things that certain mandatory standards— ANSI/ASHRAE Standard 62.1-1999, Ventilation for Acceptable Read more [...]

Luminaire Intelligence

New lighting technologies such as LED and fluorescent light sources, lighting controls, and daylighting create excellent opportunities for energy savings.  As the market shifts toward greater energy efficiency and intelligence in systems, luminaires (a.k.a. light fixtures) are the first thing to consider when planning your lighting strategy. In the lighting world, luminaires are the complete package.  Luminaires are electrical devices that integrate everything from the power supply Read more [...]
A November (not) worth remembering

A November (not) worth remembering

As I have said in previous posts, one single data point should not be used to draw firm conclusions about underlying trends in the U.S. economy. But, oh what a disappointment today’s employment report was. According to the BLS, total nonfarm payrolls did increase on net by 39,000 during November, but this gain was significantly below consensus expectations of 145,000; in addition, the diffusion index, which measures the breadth of job growth across industries, slipped to its lowest level since Read more [...]
Siting Transmission Corridors: A Real Life Game of Chutes and Ladders*

Siting Transmission Corridors: A Real Life Game of Chutes and Ladders*

Oh, for the simplicity of Chutes and Ladders! In the massive effort to attain energy independence by connecting vast renewable energy resources with energy-hungry population centers, power transmission lines are both the obstacles and the solution—the chutes and ladders—to success. Everyone wants to harness the energy from wind, sun, earth, and tides, but moving it can be tricky. Transmission corridors are the means by which energy moves from source to destination. They are integral Read more [...]
