Energy Monitoring

Energy monitoring is the process of tracking, measuring, and analyzing energy usage across buildings, equipment, industrial processes, or entire facilities. This practice is widely used to improve energy efficiency, reduce operational costs, ensure compliance, and achieve environmental sustainability goals.

Energy monitoring in Akila is an analytics tool for tracking energy usage. Monitoring objects include total usage (configured through energy usage types), equipment systems, equipment, locations, zones (configured through monitoring points), and meters. The system supports viewing and analyzing data across various time dimensions, including 15 minutes, 30 minutes, 1 hour, days, months, and years. It also provides AI-based predictions for energy usage trends over the next year.

When accessed for the first time, this page displays a default view showing energy usage data for the past 7 days for the electricity category.

You can use it to:

  • View energy usage data for all meters across monitoring points, energy types, and meter dimensions, including interpolated usage and AI forecast data.
  • Review energy usage data with year-over-year and month-over-month comparisons.
  • Gain deep insights into your site's energy usage to develop effective energy-saving strategies.
Term Description
Interpolation Mode When enabled, the system automatically fills in missing usage data during periods of data loss based on original usage values. The calculation method is: displayed daily usage = original usage on the day of data restoration / (number of days with missing data + 1). When disabled, the displayed daily usage is calculated from the original reading values. Interpolated values are marked with * in the list.
Interpolation Value In Akila, some smart meters may experience data loss due to various reasons (such as meter malfunction, network issues, IoT data transmission/reception failures, or normal meter shutdown). When data is restored, readings often show a sudden spike compared to previous values, resulting in a peak in usage (electricity, water, gas) at a specific point in time. To address this, we display these values smoothly using interpolation, creating what we call interpolation values.
Forecast Click the "Forecast" button to view AI-predicted energy usage for utility meters over the next year. You can select one or more meters to view their forecasted energy usage. After clicking "Forecast", a histogram/line chart will be generated. Selected monitoring point combinations must have at least 1 month of historical data for the AI to generate effective forecasts.
Energy Category Includes electricity, water, gas, and heat.
Data Grouping Organizes and categorizes energy usage data based on different criteria such as meters, monitoring points, or energy types, clarifying data sources.
Total Value Sum of all selected energy usage data.
% Sequential Change Compares energy usage for your selected time interval with the previous time interval. You can customize the time interval according to your needs, such as 1 day, 30 minutes, or 1 hour.
% YoY Change Compares energy usage for your selected time interval with the same period from the previous year. You can customize the time interval according to your needs, such as 1 day, 30 minutes, or 1 hour.

View Energy Usage - Energy Usage Type as Data Grouping

  1. Select the time range.
    Note: You can view data across a three-year period. If you click "Today", the usage data will be calculated based on the most recent completed 15-minute interval.
  2. Select Energy Category
  3. Select Energy Type as Data Grouping
    Note: Energy types are configured on the Energy Configuration page. Each energy type can have up to three data sources, including meter data, local data, and invoice data. When the time interval is less than one day, usage data for local data and invoice data will not be calculated.
  4. Select the nodes you want to view.
    Note: The number on the left side of each node indicates the quantity of selected nodes within its subordinate tree structure. You can also click the "+" sign to view associated meters and configured weights when the data source is "Meter Data".
  5. Click Apply
Query Result Interaction Description
Chart Can be displayed in totals mode or details mode. Totals mode shows the total energy usage of selected monitoring objects. Details mode shows individual energy usage for each selected object. Click the YoY Change % or Sequential Change % legend to show or hide the corresponding line. Only the top 10 monitoring points by energy usage will be displayed. If more than 10 nodes are selected, only the top 10 will appear.
List The "Totals" column in the query results on the right-side list page aggregates only the usage of nodes whose ancestor nodes are not checked. Click ">" to view the meter breakdown list. Click "Go to Date" to select a specific date and view that day's usage breakdown list.
Chart and List You can toggle "Full Screen" mode for a clearer viewing experience. You can also adjust the window size between the List and Chart areas to optimize the view.

  5. Select the nodes you want to view.
    Note: The number on the left side of each node indicates the quantity of selected nodes within its subordinate tree structure. You can also click the "+" sign to view meters associated with the monitoring point and configured weights. Nodes without a configured monitoring point cannot be selected and will appear in gray. You can enable the "Hide nodes without monitoring point configured" toggle below the filters to hide them.
