Overview
An interval meter, also known as a smart meter, is a device that measures pulses continually over regular intervals of time. They are frequently installed to measure usage on specific systems, building areas or buildings in a multi-building site so that their usage can be aggregated.
Interval meters typically record usage in short timeframes, such as 15-minute or hourly intervals, and store the data in the meter's memory. The data can then be downloaded in a variety of ways, based on the vintage and technology of the device. Many modern smart meters can transfer data wirelessly using internet protocols.
It's necessary to independently determine the method and format for gathering interval data from your smart meter devices. This video focuses on the creation of interval meter readings in B3 and the population of readings.
Instructions
To add an interval meter in B3, simply set the frequency to any option less than monthly. Doing so will mark it as an interval meter. It will operate with slightly different behaviors in terms of meter readings.
The Meter Editor can still be used to modify general information about the meter and view existing readings within chosen time frames. But interval meter readings can only be added through automation or through the Meter Reading Import wizard.
To import readings, launch the Meter Reading Import Wizard from the meter editor or from the Data tab. Select the interval meter and click the ‘Download Template’ button. Existing readings will be included in the template. Copy and paste your newer readings into the template and upload it.
The import process may take a few minutes.
Once processed, the interval readings will be aggregated into daily, monthly and annual usage data for analysis towards the B3 Benchmark, ENERGY STAR Score and baseline comparison. The granular data can be analyzed in the Visualizations tab at daily and hourly levels.
B3 also includes a dashboard widget catered to smart meters for monitoring daily and weekly usage.
