Cooper Controls: Building Energy Metering System
February 20, 2012
The Venergy Advanced Metering System provides complete energy monitoring for all electric and nonelectric load types including lighting, HVAC, plug loads, photovoltaic, water, and gas, among others. According to the manufacturer, the solution enables schools, commercial and government facilities, and other organizations to save energy and money; demonstrate and drive energy-usage behavior; ensure optimal building performance; and meet LEED and other energy codes. The system uses revenue-grade Accu-CT™ high-accuracy split-core current transformers (CTs) to provide the current inputs to the company’s Advanced Power Meter (APM) multifunction networked energy meter. The APM then captures power consumption data including true RMS power, energy, and demand metering. The line-powered metering device, which may be installed in a load center or junction box, enables individual or multiphase measurement of voltage, current, power factor, reactive power/energy, and line frequency without any additional power supply required. The Venergy Data Acquisition Server shares metered data from the APM with a hosted cloud computing server that manipulates and stores data. The system’s web-based application and dashboard provide remote access to real-time energy-consumption data through an intuitive graphical user interface. A Venergy mobile app is also now available from the iTunes App Store, allowing users to view real-time energy consumption of their building on an iPad®, iPhone®, or iPod Touch®.
