$Green$ I.T. network-based LED

GreenEconomyPost- Huge Cost Savings Achieved with LED Lights Using Network Cables
A network-based LED lighting technology for commercial buildings optimizes energy-efficiency for commercial lighting and provides comprehensive sensor data for building performance.

"The holy grail right now for real estate is creating interoperability between information technology networks and the electrical grid." Mr. Gilbert said. "Your ability to run an efficient building is important in order to remain competitive."

"Redwood's vision is to use LED lighting's low voltage to power not just lighting, but create a digital network to manage and efficiently optimize lighting, heating, venting, air conditioning, plug loads, window shading, and just about everything else that uses power in a building," said Leonard. "Using a network-based platform approach, we will deliver smart lighting systems that revolutionize how lights, and buildings, are powered, controlled, and optimized."

The system could also optimize energy use based on utility rates and pricing programs and the instrumentation capability allows management of lumen depreciation and ensures the system doesn't over-drive the lights.
How Redwood Systems saves money
Additional energy savings comes from using sensors and a central controller to reduce light use. The company has also developed a method for using those same power cables to carry data. Each LED can be fitted with inexpensive sensors that provide detailed information about temperature and where people are in the building.  This is information that can be used to control cooling and heating systems. These sensors can be also be used to optimize light levels and ensure the lights are operating efficiently. Such sensors can also  The sensing and controls add very little cost to the new system because the network connections and power supply for the sensors are already in place.
