Electric meter are changing. Over half are now “smart” (a/k/a interval or digital) meters that measure and provide electricity usage in short (e.g., 15-minute) time intervals, instead of only once a month. Smart facility managers and executives are using that data to find opportunities to cut power costs, find better electric rates, and ensure that efficiency and renewable energy projects will actually save them what their vendors claim.
Through a brief overview of how the metering landscape is changing – and why that’s important – the presentation shows how to secure, manage, and graphically interpret the interval data stream provided by the new meters. Examples are shown using Excel’s 3D graphing techniques. Sources of professional software to analyze and chart interval data are reviewed, and a free source is highlighted.
Charted examples visualize problems in building operations and procedures that resulted in excessive peak demand charges, failures in equipment, and bogus claims of potential dollar savings.
