Enlighted, a startup using sensor and big data software to control lighting and power in large commercial buildings has hit a few milestones this week. The company, which we put on our 12 smart grid startups to watch in 2012, has raised a sizable $20 million round, and has also doubled the size of the building space under management over the last five months, to hit 10 million square feet of commercial real estate.
Enlighted says its customers include Google (s GOOG), LinkedIn, Bank of New York, Turner Broadcasting and the City of San Jose. New investors RockPort Capital and DFJ JAIC joined the round, along with existing investors Kleiner Perkins, Draper Fisher Jurvetson, and Intel Capital.
The startup’s lighting control tech can individually measure and manage lighting at each light fixture and can cut energy consumption from lighting in office and commercial buildings by 50 to 75 percent. The sensors can detect light level, occupancy, temperature and power consumption in the 100 square feet under each light. The company says it’s saved some 15 gigawatts of electricity since it began installations two years ago.
Enlighted’s first customer was green carpet company Interface Global, which used the lighting management system on its 35,000 square foot facility located in Acworth, Ga. Interface says it was able to cut its lighting power by 70 percent, and achieved a return on investment in 18 months.
Big data analytics and sensor tech — IT — is appearing as one of the bright spots in cleantech startups these days. Some investors call this the so-called Clean Web, or using digital tech to manage resources from energy to water to food.
