The network of lighting in every room provides an opportunity to create an information rich “smart” building that redefines how we interact with our living environment. In addition to saving energy, the smart building can adjust the temperature in the room, improve air quality during occupancy hours, and, in case of an evacuation, identify the number of people still remaining in a room. This video interview with Jeremy Stieglitz of Redwood Systems, the winner of GreenBeat Innovation Challenge 2010, profiles their technology that brings together efficient LED lighting and a rich data network on new and renovated buildings. With Redwood Systems’ technology, the upper half of every floor only contains a low voltage DC circuit instead of the usual high voltage AC. This change translates to significant short term savings in wiring and labor that can make the payback immediate on a system by Redwood Systems. On the long term, a LED and data backbone enables “smart” building technology such as daylight sensors with lighting control, temperature sensors with temperature control, and environmental sensors with air quality control. Sounds like a building that can talk may be upon us very soon.
