Communication Bus Offers Simplicity in Installation and Flexibility with Existing Building Automation Systems

March 29, 2012 - North American lighting leader, OSRAM SYLVANIA, has introduced GreenBus II, a new, two-wire communication platform for supplying data and power to the ENCELIUM Energy Management System from OSRAM. The new communication network integrates lighting control and energy management into one complete, programmable architecture.

"GreenBus II is highly flexible," said Terry Mocherniak, director global business development, LMS business unit of OSRAM SYLVANIA. "The network can integrate with both DALI and analog 0-10V dimming lighting systems." In addition, the ENCELIUM Energy Management System is BACnet® compatible for easy integration with existing building automation systems, such as HVAC, fire and security.

This next generation bus system dramatically raises the capability to deliver power to sensors on the bus while increasing the number of nodes supported by a single ENCELIUM Energy Control Unit. GreenBus II includes enhanced troubleshooting features over the GreenBus I architecture, such as the ability for the system to detect and locate field bus communication faults via the ENCELIUM Polaris 3D™ software.

The ENCELIUM Energy Management System is unique in that it can integrate control of either DALI dimming ballasts or 0-10V analog dimming ballasts within the same platform. 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 2 and Class 1 wiring within the same lighting system. Where analog ballasts are preferred, the system utilizes a Luminaire Control Module (LCM), which provides 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 as soon as it is connected to an ENCELIUM Energy Control Unit (ECU) and adjusts itself to the type of sensor it is wired to, establishing two-way communication between the ECU and itself.

"Individually addressable, the Luminaire Control or Sensor Interface Modules enable each device to be independently configured to best meet the needs of a building or facility," said Mocherniak. "And because the system can be easily re-configured via the ENCELIUM Polaris 3D software without any re-wiring, it is an ideal solution for both new construction and retrofit projects."

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. "Through the simple click of a mouse, lighting is now a truly controllable energy load," said Mocherniak. "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 costs up to 50% - 75%.

"The bottom line is that the ENCELIUM EMS delivers the shortest possible payback generated by energy savings, while simultaneously improving both lighting quality and personal lighting comfort," said Mocherniak.
