Green Edge Systems, Inc., a trusted leader of real time energy savings, predictive maintenance and temperature monitoring solutions for campuses, schools, hospitals, sponsor of the 18th National Energy Services Conference (AESP) to present its GreenGuard state-of-the-art hardware products, software and communication platforms at the AESP's 18th National Energy Services Conference, Hilton Clearwater Beach Resort, Clearwater Beach, FL, January 28-31, 2008.
GreenGuard continuously monitors the savings and the actual energy and maintenance bills and helps deliver increased ROI, boosting savings with a continuous improvement approach.
The hardware products are comprised of a variety of powerline, wireless, wired and stand-alone low cost introductory products, making it affordable to any size campus. Two way communications allow automated control of devices in response to price, peak load shaving or demand reduction signals.
The software platform utilizes advanced business Intelligence (BI) tools that allow dynamic energy management, effective demand response, peak load shaving management, energy savings, predictive maintenance and temperature monitoring in one integrated system.
This platform allows implementation of demand response, peak shaving, Carbon-Trade and other future energy efficiency, energy savings and greenhouse gas incentive-based programs.
Initial energy and maintenance savings of over 20 percent, achieved by the basic system, allows its introduction into campuses, with savings that are much higher than the initial investment in its first year. The savings in following years remain with the customers. The communication and management platform allows the addition of any current and future energy saving systems as an additional module.
The GreenGuard wireless Zigbee sensors use Ember's chip and EmberZNet PRO networking software platform, which supports the ZigBee PRO Feature Set, to communicate with ZigBee-enabled devices.
The system interfaces the network with load control devices, enabling efficient management energy consumption during peak load demands, among its many other intelligent applications. The bi-directional system also continuously measures and displays active energy delivered , letting customers see where, when and how energy is being consumed. This helps customers actively participate in the conservation of energy and contribute to protecting the environment, while also managing their costs for power. http://www.ember.com/press_release.html?id=237
Ember's technology is integrated in smart meters that support time-of-use pricing, load profile data and other advanced features required for "Smart Grid" initiatives, such as California's Title 24 regulations aimed at modernizing the electric grid to reduce peak demand.
Ember's strength in home and building automation yielded another award in 2007, with its ZigBee technology platform being named the "Best New Wireless Product" at the BuilConn Conference in June. http://www.ember.com/press_release.html?id=192
The Green Guard wireless sensors communicate with these Smart meters and assure significant savings once these meters are installed by the utilities.
According to a paper by The Brattle Group ("The Power of Five Percent," May 2007), best available technologies, like ZigBee, can help reduce peak electricity demand by at least five percent over the next few years. The paper goes on to say that this reduction could save consumers more than $3 billion in annual electricity costs, and help reduce the $50-$100 billion in losses that businesses suffer each year due to power outages and brownouts.
Green Generates Green -- is the topic of many articles such as HVACR Business. Green Edge Systems, Inc. proves that there is immediate return on the investment in its GreenGuard Platform, with annual savings of up to 35%.
Visitors at the conference will be able to view the dashboard software that monitors the energy savings, predictive maintenance, temperature monitoring and the various elements of the GreenGuard sensor platform.
The GreenGuard sensor platform includes a family of state-of-the-art wireless sensors with the following features:
- Wireless Data logging
- Internal Relative Humidity/Temp sensors
- 4 recording inputs: 4-20mA, 0-1V, Pulse counter, PT100 2-wires, NTC, Thermocouple J, K and T , door sensors
- Dry contact in each wireless sensor
Other sensors in the GreenGuard family are:
- A wired logging device - ideal for smaller installations
- A low cost USB temperature recording device that allows 24/7 temperature monitoring at a cost per location with two measuring point of under $200 per location
- Multiple input temperature recorder and refrigeration controller
- Multiple input temperature recorder, refrigeration, air conditioning and lighting controller
In multi location installations such as in school districts, a mixture of the above sensors can be installed, all managed through advanced dashboard application software.
To better understand the uniqueness of Green Edge Systems offerings, ask any provider of energy, maintenance and temperature monitoring solutions if they can provide the following GreenGuard capabilities:
- Monitoring and controlling of energy usage and saving, resulting in up to 20% energy savings
- Immediate alerts when the refrigeration system is not working or malfunctioning.
- Prediction of compressor or other system failures with alerts to avoid critical damage, similar to the red warning light in your car before a critical engine failure. We provide the same type of alerts when compressors are about to fail, with no additional equipment. Would you buy a car without this feature? Can you afford buying a monitoring system for your refrigeration system without this feature?
- Immediate power outage alert with no additional equipment.
- Highly affordable - starting at under $200 per location, provides 24/7 temperature recording, reporting and alerts.
- Wireless sensors that fully implement the Zigbee Mesh Networking Protocol -superior to Zigbee in a point-to-point mode which may fail with future network saturation.
- Bi-directional communication between the system and the sensors, allowing for seamless setting of sensors to new parameters such as immediate response on momentary door openings nights and weekends, different parameters of temperature settings for night and weekends, use of lower priced energy at night and more.
- Over-the-network firmware updates, eliminating the need for on-site technician.
- Calibration of the sensors over the network.
- Temperature readout on each sensor, gateway and repeater.
- Temperature and door opening samplings, customer-configurable, even once per minute or less, allowing for better control of food quality, alerts and more.
- Local alerts even when the network is down.
- Power backup on each sensor - sensors continue to collect data, even if battery fails or if power is out.
- Low cost repeaters to extend range of coverage.
- Multiple input sensors - more then 4 inputs per sensor.
- Every sensor has its own Dry Contact, allowing connectivity to a building/HVAC/energy management system. Detailed alerts from each sensors are provided even if the network in down.
- Data is never lost in a power outage and there is no need for uninterruptible power supply (UPS).
- Prevention of unnecessary defrost cycles.
- Monitoring food temperatures in addition to air temperatures.

Also on display, GreenGuard Econair by Nortex, a powerline carrier communication system. The system is based on the eLOG mini PLC (Programmable Logic Control) device.
The eLOG can be configured as a smart controller for air conditioning, coolers, chillers, light dimming, appliances control and interfacing with sub metering for total energy reading, temperature monitoring, analysis and real time power factor corrections.
The eLOG is uploaded with configuration via the powerline communication by the main concentrator terminal DCT-11 which is a gateway for up to 1024 eLOG devices.
The GreenGuard Econair by Nortex powerline communication is based on a combination of a spread spectrum DSP (Digital Signal Processing) modem meeting the CENELEC Std. and an intelligent dynamic adaptive mesh networking layer, using real time updated relaying feature according to environment power grid conditions for a significant coverage performance. First installations of GreenGuard Econair by Nortex, fully integrated with the Green Edge Systems dashboard platform are expected later in 2008.
Reliable powerline communication is by far the best way of communication in campuses such as hospitals and Schools. No special installation is needed.
Green Edge Systems provides you with the best of both worlds - affordable and efficient powerline technology combined with wireless sensors to provide extended reach as needed in conjunction with wireless applications.
