OSRAM SYLVANIA and Encelium Showcase Industry Leading Light Management Systems at LIGHTFAIR International
The ENCELIUM™ Energy Management System Can Reduce Energy Costs from Lighting Up to 75 Percent

Las Vegas and Danvers, Mass. (May 9, 2012) – Committed to the advancement of sustainable lighting systems, North American lighting leader OSRAM SYLVANIA  is proud to showcase the industry leading portfolio of Encelium Technologies at this year’s LIGHTFAIR International Conference. Acquired by OSRAM SYLVANIA in October of 2011, Encelium is a leading software technology development company concentrating in advanced lighting control and energy management systems for commercial and industrial buildings.

GreenBus II™

GreenBus II is a new, two-wire communication platform for supplying data and power to the ENCELIUM Energy Management System (EMS) from OSRAM.  The new communication network integrates lighting control and energy management into one programmable architecture. The network can integrate with both DALI and analog 0-10V dimming lighting systems and is BACnet® compatible for easy integration with existing building automation systems that manage the operation of systems such as HVAC, fire and security.

Where DALI ballasts are preferred, the system utilizes an ENCELIUM DALI Bridge as a gateway between the ENCELIUM GreenBus II field bus and the DALI ballasts.  The DALI Bridge also allows for the mixing of Class 1 and Class 2 wiring within the same lighting system.  Where analog ballasts are preferred, the system utilizes a Luminaire Control Module (LCM) which provide for addressable control (dimming or switching) of each device.  The LCM is also able to control LED fixtures and dim 0-10V LED drivers.

The system also utilizes a Sensor Interface Module (SIM) to integrate standard occupancy and photo sensors into the ENCELIUM GreenBus II communication network.  Each SIM is automatically addressed when it is connected to an ENCELIUM Energy Control Unit (ECU) and adjusts itself to the type of sensor to which it is wired, establishing two-way communication between the ECU and itself. 

Polaris 3D™

Polaris 3D is the next generation of lighting control software for the ENCELIUM Energy Management System. Eliminating the need for software installation, Polaris 3D enables users to access to the control system via a simple web-based application that provides 360°, three-dimensional navigation in a multi-floor view of a facility’s lighting energy use. This results in increased security, faster set-up and start times, and easier integration with other web-based building control systems. Polaris 3D provides users with a unique color gradient representation of lighting system data, such as lighting status (on/off), power density or energy consumption, light levels; occupancy status; load shedding status; and comparative energy trends. The central software enables facility managers to group floors, rooms or even desks into zones and control them as a unit. Users can instantly rearrange lighting layouts by moving a zone from one area to the other with just a click of their mouse. Polaris 3D also provides the ability to change light levels anywhere in a complex, modify default levels and set lighting time schedules.

With the GreenBus II communication network and Polaris 3D software, the ENCELIUM Energy Management System offers unprecedented flexibility and control of a building’s lighting usage. Facility owners and managers now have the ability to incorporate lighting as a component of a portfolio-wide energy management program. The use of control software allows the ENCELIUM EMS to respond quickly to ever-changing building characteristics and requirements.

Benefits of the ENCELIUM EMS include everything from improved workplace ergonomics and productivity, to complying with building codes and energy efficiency requirements, and promoting a building’s “green” image and LEED® certification efforts by reducing lighting energy consumption up to 50 to 75 percent.
