Meter Monitoring Goes High-Tech to Save Energy

Energy and Climate Community Engagement and Education Internal Culture

Duke Energy provides a Campus Real-Time Metering service that enables the University to monitor and provide energy usage information from 41 electric meters. The system uses Duke Energy-owned meters and infrastructure, as well as newly installed meters.

The meter information is gathered using a combination of IP networking and RF communications technology to gather data from each meter. The information is available to JCSU on a real-time and historical basis via web browser on a PC connected to the campus network. Data transfer regarding demand and energy usage is available to integrate into the BMS utilizing BACNet protocol communications over ethernet.

Extensive reporting, including trending, comparisons and normalization, is available for JCSU personnel using the Vykon Energy Suite to manage the energy usage and track energy management actions and results.

Other services include a real-time kW display of all metered locations, kW and kWh reporting, in addition to cost allocation broken down by each University department or individual buildings.

A periscope dashboard is a configurable, browser-based dashboard application that provides identification of real-time data and historical trends in the rapidly changing environments of multifacility operations. These dashboards reduce volumes of data from disparate systems into visual knowledge, providing the opportunity for users to quickly identify issues, assess relationships and take action in order to optimize resource efficiencies.

It was designed to provide each user with a unique dashboard client. The dashboard can easily be set up and modified from a growing library of “viewlets” by any user without affecting other users’ preferences and settings. A growing library of viewlets empowers users with an ever-expanding offering of visualization options for various types of data. Typical viewlets include drill-down column and pie charts, history line charts, baseline comparison charts and year-to-year charts.

The system also provides the ability to normalize data such as energy consumption and account for differences such as square footage.
