Lights consume about 22 percent of the electricity in commercial buildings and are a huge target for waste reduction. Just think of all the lights you see left on in downtown office buildings at night. But only about 7 percent of U.S. buildings have any kind of lighting controls, creating a wide-open market for wireless technology to come in with a solution.

Daintree Networks and Adura, two startups in the wireless lighting controls field, share a lot of similarities in the way they’re attacking the problem. Both use wireless gateways and lighting fixtures to enable energy-saving strategies like turning off lights after work hours, as well as more complex tasks like linking them to occupancy sensors or natural light monitors to subtly shift lighting over time.
