OP-T2-17: Energy Management System

The University has an integrated energy management / utility accounting system in place that controls and tracks energy consumption and building performance on a building by building basis. The campus system integrates several different platforms to deliver the integrated view of the campus. BUILDING ENERGY MANAGEMENT AND CONTROL SYSTEM (BEMCS) The primary BEMCS for the campus is a Johnson Controls Metasys system.This system runs all of the HVAC systems on campus. In addition it is responsible for seasonal space temperature setbacks, controlling occupied, standby and unoccupied building operating schedules and for building energy metering for thermal streams (steam, chilled water, heating water, etc.). ELECTRICAL POWER METERING AND MANAGEMENT Campus electrical energy and power measurement is accomplished using a Schneider / Square D SPM7 power management system. This system meters energy and power data at the building level, as well as provides power quality data for the building. ENERGY WITNESS UTILITY MANAGEMENT PLATFORM Energy Witness by Interval Data Systems acts as the clearinghouse for energy data on campus. This application provides accounts payable bill processing so all purchased utility billing data is entered into the system. The application also pulls utility metering and operational data from the other systems into its unified database for accounts payable cost allocation. Because it retains all of the utility information, the data is made available to the campus via web reporting from the database.
