Facebook Turns to Smart Lighting for Data Center

Facebook Turns to Smart Lighting for Data Center
Facebook’s new data center in Oregon has gotten its fair share of attention, both for Facebook’s decision to open up the energy efficient design, and also for Greenpeace’s campaign to try to convince Facebook to stop powering it with coal. But here’s another reason to recognize the data center: Facebook has installed a smart lighting system courtesy of startup Redwood Systems.

Sam Klepper, Chief Marketing Officer for Redwood Systems, tells me that Facebook is currently using Redwood System’s technology to control over 1,000 lights in Facebook’s data center in Oregon, and Facebook plans to add the lighting system to the rest of the buildings at the Oregon data center shortly. Klepper says Redwood Systems is also talking to Facebook about implementing the technology in Facebook’s upcoming data center in North Carolina.

Redwood Systems makes lighting digital, networked and intelligent. The 3-year-old company makes a control and sensor system for LEDs (light emitting diodes) that runs over an optimized version of ethernet cables. Commercial building owners and data center operators can use the LED lighting control and management system to cut the amount of lighting used throughout the building, in some cases up to 70 percent over standard non-networked fluorescent lighting systems. LEDs are more efficient than fluorescents, but Redwood’s management system also monitors the building environment, including temperature and room occupancy, and can dim and manage the lights to help maximize efficiency.

Klepper told me that a typical return on investment in terms of energy savings for the lighting system, is between two to five years after installing the system, depending on different factors. Around 40 percent of Redwood System’s customers right now are in the data center space, said Klepper, who added that that percent will likely grow over the coming months and years. Klepper also said that Facebook is interested in the lighting technology partly because it is combining lighting efficiency with overall building intelligence, and Redwood’s sensors can alert managers when panels for hot/cold aisle containment have been left open, or , say, when there is movement in certain sections of the data center.

Redwood uses its optimized communications cables to send both a digital signal (zeros and ones of information) as well as power, and each LED fixture contains an embedded sensor that can monitor the environment of the room. The LEDs are then connected to the centralized Redwood computing engine.

Dave Leonard, co-founder and CEO of Redwood Systems, left Cisco’s wireless division to start the company. The company is backed by at least $27 million from Index Ventures, Battery Ventures and U.S. Venture Partners. There are a variety of competitors that are offering similar lighting management systems, including Digital Lumens, and Adura Technologies as well as offerings from the building automation companies Honeywell and Johnson Controls.

Smart lighting could be a massive market. The Electrical Power Research Institute (EPRI) reported that only 7 percent of the U.S. commercial and industrial market have installed lighting control systems of any kind.

Miami Heat Melodrama Doubled TV Ratings

Miami Heat Melodrama Doubled TV Ratings
The Miami Heat have yet to win any championships with the Big Three of Dwyane Wade, LeBron James, and Chris Bosh, but they have already proved to be among the elite in one category: local television ratings.

Sports Business Journal obtained local TV ratings for 28 of the 30 teams in the NBA this week, and the Heat were the third highest-rated team in the league this season, behind the San Antonio Spurs and Utah Jazz.

Technically that would make the Heat the most watched team in the NBA located in a city that actually has entertainment options and a night life.

The Heat averaged a 4.94 local rating, a 99.2 percent improvement from the 2009-2010 season. That doubling of TV ratings is also the second biggest ratings jump of the past year, behind the L.A. Clippers (whose ratings rose 130 percent thanks to the Blake Show).

In the 2009-2010 season, when D-Wade led the Heat to a 47-35 record and playoff berth, the team drew a 2.48 rating.

What made matters worse is players on the team like Michael Beasley would have rathered tuned in to SpongeBob Square Pants than watch his own team struggle to beat the Toronto Raptors.

But oh how times have changed. And no one likes a good melodrama like a Miami sports fan.

Miami has long been called a bandwagon sports town, where local teams can only draw fans when they win. Now we have more proof.

And what Heat victory would be complete without a mention of the toils of the Cleveland Cavaliers.

LBJ's former team saw their ratings fall 54 percent to 3.93, the steepest decline in the NBA. Not even Anderson Varejao's hair could keep Clevelanders from tuning out the Cavs and turning the tube to see what the fuss is about on South Beach.
