Encelium Technologies energy control system promises significant energy savings

Encelium Technologies, Inc.'s Energy Control System (ECS) is a fully scalable, integrated hardware and software system that allows users to realize unprecedented lighting-related energy savings in offices, healthcare facilities, schools, warehouses, factories, and other commercial and public buildings. The system's unique "GreenBus" communication network allows light fixtures, occupancy sensors, photo sensors and wall dimmers to be individually addressed as part of a complete lighting control system, resulting in quantifiable energy savings of 55-70% — while at the same time improving lighting quality, occupant productivity and workplace ergonomics. Every lighting fixture may be individually controlled from a PC or via the Internet by an employee or building energy manager. The dramatic energy saving achieved by the ECS greatly accelerates system "ROI" compared to standard energy management strategies, offering net paybacks typically ranging from two to three years.

The highly flexible ECS allows seamless integration of any or all of the following critical commercial building lighting energy management and control strategies, including:

  • Daylight Harvesting by means of photo sensor-based automatic lighting-level adjustments;
  • Task Tuning via individual lighting-level adjustments based on task or work space needs;
  • Occupancy Control through occupancy sensor-based lighting-level on/off and high/low controls;
  • Time Scheduling by means of time-based on/off zone lighting control;
  • Demand Response - Load Shedding via dimming to accommodate energy price spikes or demand limits;
  • Personal Lighting Control through PC-based workspace lighting adjustment to personal preferences.

"Today's top-selling lighting controls and relay-based switching schemes can't hold a candle to the ECS in terms of functionality and energy consumption and demand cost savings over the full spectrum of commercial building applications," said Don Millstein, Encelium President & COO. "As a dramatic demonstration of the ECS technology, a 95,000 sq ft building in the Toronto General Hospital complex reduced consumption by 74% and demand by 37% — saving $47,000 in annual energy costs."

The heart and brain of the system is the Energy Control Unit (ECU), a rack- or wall-mount processor unit that employs the company's unique GreenBus network to communicate with individual light ballasts (120, 277, or 347 V) and occupancy/photo sensors via a universal I/O interface module in each fixture. The sensor's 12 VDC at 25 mA power is supplied over the GreenBus network, which eliminates the need for separate power supplies and wiring. Using standard Cat3/5 cable, GreenBus comes with quick-patch "click and go" connector cables for fast, easy installation.

The graphical user interface for the cULus-listed ECS consists of Encelium's Central Control Software (CCS) and Personal Control Software (PCS) that allow any workstation to perform direct lighting control and other energy management functions via the facility's existing LAN wiring.
