Power Monitoring System

The standard LonWorks Power Monitoring Panel uses one Echelon i.LON100 Internet Server with up to three Continental Controls Wattnode wattmeters to monitor and record power information.  The Wattnodes LonWorks devices, connected by twisted pair cable to the i.LON100, which can be located near a phone line or network connection to provide communications for data retrieval or real-time monitoring. 

The i.LON100 may communicate via Internet or by phone using a built-in modem.  Data can be sent automatically by email to VaCom’s EnergyDashboardÔ server, or retrieved manually into Excel using built-in XML code or as a .csv file via FTP file transfer.

Monitoring Options:  The Power Monitoring Panel can be configured with numerous options, including:

  • Two pulse meter inputs to read utility power meters, gas or water meters

  • Temperature and pressure monitoring using LonWorks analog modules

  • Demand management functions to send email message upon reaching preset demand levels on utility meter

 

Critical Price Signal Configuration:  A configuration has been developed to help facility operators respond to critical peak pricing (CPP) rates being implemented in California.

Project Example

VaCom provided a customized monitoring system for the National Resouces Defense Council Robert Redford Building in Santa Monica, California, to monitor overall building performance including power usage, solar electric generation, water use and rainwater recovery, as well as HVAC and lighting system performance.  The system used three i.LON100’s to provide long term data storage and host extensive web pages graphics, connected to an array of LonWorks input modules.  In addition, VaCom programmed a custom “analytics” module to calculate the aggregate building efficiency compared with a base case building, using current weather conditions.
