. . . to $7 billion, according to Forbes. The story includes:
So how to make LEDs mimic incandescents? The key was in redesigning the structure in the middle of the bulb called the filament tower, where 10 or 20 LEDs of varying colors are arranged. Cree’s configuration let the individual light sources overlap, creating an omnidirectional glow.
For now Home Depot is the only place you can buy the Cree, part of an exclusive deal to roll out the bulb in more than 2,000 stores. “The exclusivity is to be negotiated. We will look at other partnerships at some point,” says Swoboda.
And — to the magazine’s credit — the article included this:
But bulbs are just the start. Because they seldom need to be replaced, LED lights can be built into fixtures and furniture. Professor Michael Siminovitch, head of the California Lighting Technology Center at UC Davis, envisions a world of LEDs programmed to change color and intensity throughout the day, matching light from the sun.
Since humans’ circadian rhythms take cues from sunlight, Siminovitch thinks smart LED lighting will improve moods and reduce seasonal depression. Cree and its rivals are making “really, really good first steps” toward this future, he says.
Bernie Markstein – who worked for the Home Buildings (NAHB) for a long time — is now chief economist at Reed Construction Data. He recently posted an “Economic Nuggets” item full of stuff, some of which is really interesting to think about. Here are the first two:
- The second estimate of first quarter 2013 real (inflation-adjusted) gross domestic product (GDP) resulted in a minor downward revision in the previously reported growth rate―from 2.5% at a seasonally adjusted annual rate (SAAR) to 2.4%. This estimate is based on more complete data than the first estimate, but will be updated further near the end of June
- Investment in nonresidential structures was revised down from a 0.3% decline to a 3.5% drop
#1 — GDP in the first quarter, a relatively good quarter compared to expectations, was slower than originally reported. It may yet get revised (down or up) a hair. Was this the worst of 2013 . . . or the best we’re gonna see?
#2 — BIG revision in “investment in nonresidential structures.” Really big. This is the national accounts tracking category for construction of buildings that are NOT houses. What happened?

. . . new from the U.S. DOE, it says here. Of note:
This database will allow users to access energy performance data and perform statistical analyses on more than 60,000 commercial and residential buildings across the country, and new records are being added regularly. The database includes buildings’ location; age; size and function; electricity and fuel consumption; equipment information and operational characteristics.
The data can also be used to compare performance trends among similar buildings, identify and prioritize cost-saving energy efficiency improvements, and assess the range of likely savings from these improvements
ABI Research is out with info on the distributed antenna systems (DAS) piece of the wireless market.
There is a fierce battle raging between Distributed Antenna Systems (DAS), Wi-Fi, and licensed small cells for coverage and capacity in enterprise wireless systems. Each type of system has its strengths and weaknesses with Active DAS systems the choice for large corporations which we define as over 100,000 square feet and with more than 100 employees.
Small and Medium-sized Enterprises (SMEs) have the choice between Wi-Fi and small cells.
EleBlog has hosted previous articles on DAS, including this one.
From Albany GA:
The highlight of the evening was the naming of the chamber’s Small Business of the Year. The winner for 2013 was A-West Enterprise LLC, located at 705 Canal St.
An electrical contractor in Albany since 2009, the business was begun by Angie and Eddie West, Garrison Jones, Lavon Davis, Jeremy Meads and Chris Joiner. Today, the company employs about 40 people.
The secret to our success is to put God first and give him credit for everything,” said Eddie West, who accepted the honor for his wife, Angie, owner A-West Enterprise.
Hardy said the race for the top spot was a real squeaker between top dog A-West and runner up Stewbo’s Enterprises, a restaurant group that includes Harvest Moon, The Catch Seafood and Henry Campbells Steakhouse.
One analysis: The general drift of this segment of the article is that the people at Stewbo’s are a bunch of godless communists.
Read this item. Not only did a NC state senate committee move an anti-solar bill, but the video evidence seems to show that the vote went THE OTHER WAY . . . in a voice vote. The “pro” anti-solar senators refused to do a follow-up headcount.
This is news, but it shouldn’t really be. Stupidity IS Obstinate!
Read this full ASHRAE note. Here’s a slice:
In North Carolina, the latter situation may be coming to pass. If enacted, House Bill 201 would repeal statutorily mandated adoption of the 2012 state code and revert back to the 2009 edition, which are 30 percent less efficient than the 2012 code. The 2012 code includes a requirement for commercial buildings to either comply with Standard 90.1-2010 or to be 20 percent more energy efficient than Standard 90.1-2007.
Among its many concerning characteristics, the bill would, as a representative of the American Chemistry Council put it, “cause the state to miss out on significant energy conservation and will put North Carolina in the bottom tier for states in energy efficiency.”
According to this Insurance News item, Subguard is
a type of subcontractor default insurance that indemnifies general contractors from the costs of a subcontractor defaulting on performance obligations.
