PHILADELPHIA, April 23, 2013 /PRNewswire/ -- As energy-efficiency, digital technology and software converge, Philips continues to prove its leadership in LED lighting by previewing the next innovation for the office with SpaceWise technology at the Philips booth #1401 during LIGHTFAIR International. Designed for large, open plan office spaces, SpaceWise is integrated with the Philips DuaLED luminaires, embedding wireless controls in each fixture to provide presence detection and daylight harvesting, allowing them to be automated. Because each fixture has its own intelligence, yet acts as part of a mesh network, the system eliminates the need for re-wiring or additional building controls, as well as the need for human intervention with the lighting system. Lighting constitutes 30-35 percent of total energy load in commercial buildings. There are over 4.9 billion non-residential buildings in the US and over 72 billion square feet of commercial space, of which 19 percent are offices. Private offices have long been served by room-based occupancy sensors, but the cost and complexity for new controls design and wiring has been a primary barrier to adoption. Open plan offices are especially difficult to re-wire for controls due to pre-existing building zones and circuits. With two- thirds of today's office space being open plan, SpaceWise becomes a breakthrough technology to achieve deep energy efficiency where it previously wasn't possible. Because the intelligence has been on-boarded in the Philips DuaLED luminaire, SpaceWise technology makes installation easy, accelerating adoption by making it simple enough to be suitable for both retrofit or new design applications. The SpaceWise system is not tied to pre-existing zones and functions as a stand-alone system with application appropriate granular dimming that is occupant-friendly. In addition to the energy savings inherent to Philip LED luminaires, using layered advanced lighting controls can increase energy savings by 20-30 percent for a cumulative savings of 50-75 percent.
