Adding a physical meter the software is to communicate with.
Users can define forecast data to be entered. This function allows a forecast values to be tracked against actual for comparison.
Users can enter manually meter data. For example; a meter that is created using data received from only monthly utility bills which must be manually entered. Bulk data upload can be done via CSV.
Calculation Meter Types
An aggregate meter is the sum of all associated meters.
Custom calculation meters require the calculation expression or equation to be defined. Available calculation operators are +, -, *, /, ().
A portion meter is configurable to a specified percentage of a given parent meter.
A remainder meter is the remainder of a parent meter minus its child meters.
The Optergy software can communicate to meters via the following methods:
- Modbus RTU
- Modbus TCP/IP
- BACnet MSTP
- BACnet IP
Specific Meter Drivers
There are four specific meter drivers built into the Optergy base license. This allows Optergy to communicate via proprietary manufacturer protocols to the following meters:
- IME Nemo 96HD with IF96012 Memory module
- EDMI Atlas Series
- EDMI Genius Series
- Novus DigiRail 4C
Meter Type Templates
Meter type templates can be created and saved for the following utility types:
- Thermal energy (chilled & hot)
Optergy has 17 Modbus meter type templates saved as standard. Standard templates included in Optergy’s base license are for the following meter types:
- Ceice Electric Technology PMC-53M Series
- Crompton Integra 1630
- IME Nemo 72L
- IME Nemo 96HD
- Pilot PMAC625
- Pilot PMAC735
- Pilot PMAC770
- Schneider Electric PM700 Series
- Siemens Sentron PAC3200
- Socomec Diris A40
If a meter type does not exist as a standard, the user can create their own BACnet or Modbus meter type template. These templates can be exported/imported for easy setup on multiple projects.
Automatic Meter Reading
The automatic meter reading function provides users with the ability to select individual meters and generate summary reports as CSV or PDF.
The report includes information such as a selected date (based on a time period selected by the user), the meter name, serial number, and the meter reading. These reports can be sent to users via email automatically as CSV or PDF.
Automatic meter readings can be used where a building owner recovers utility costs from tenant through their lease agreement without the need for a formal utility bill.
Energy Log Management
The energy log management page shows the user a list of all current energy logs recorded in the Optergy database. The list shows each energy log’s name, parameter and description.
The Optergy software has built-in functionality to scan for data anomalies; such as temporarily spikes and drops in data that are occasionally caused by malfunctioning metering hardware. This scan can check all energy logs or just those selected from the table.
Users can remove abnormal data via user selectable time period, or upload data via CSV. Energy logs can be automatically emailed for a user defined period as raw 15 minute interval data or by user selectable break up intervals. For example; reading totals for daily, weekly, monthly or yearly.
Meter Hierarchy Management
The meter hierarchy page loads a graphical tree list displaying the parent/child relationships of all the meters currently in Optergy software.
When a user right clicks on a meter a drop down quick link menu will link the user to further information including:
- Meter breakdown report (only available for parent meters)
- Meter configuration
- Meter commissioning history
Custom Meter Points
Custom meter points allow the user to create a BACnet point to view cumulative data for a meter within a user defined time period. For example, the user can create a custom meter point to view consumption for the previous day, week, month or year. The custom meter point’s data is stored as a BACnet Analog Input (AI) which can be trend logged, displayed on a graphic display, energy dashboard, and reports.
Custom meter points are updated every 15 minutes.
Optergy software allows users to configure alarms for meters.
Users can be notified of new metering alarms in three ways:
- Appear and be displayed in the Optergy software banner
- Received as alarm emails with URL link to the meter in alarm
- Notification via Optergy mobile app banner alert
Alarm conditions include:
- Configuration changed
- Meter online
- Meter offline
- Instantaneous maximum and minimum values
- Consumption over interval
- Consumption over time
- Outside tolerance levels
Adjustable alarming conditions allows users to create context around the alarms being generated. For example; if a cooling tower top meter is installed, the user can define alarms that identify unusual water consumption outside of normal operating hours. This can identify if the typical ball valve and float water top up has failed open or closed.
Meter Display Templates
Once a meter is set up in the Optergy software, a meter display page is automatically created based on the data available as defined by the meter type template. All data points on the meter display page are automatically logged so that engineering time is kept to a minimum during project delivery. Users can toggle the prebuilt report from day, week, month, year, consumption, demand or carbon emissions.
Custom Displays - Single Line Diagrams
Using Optergy’s built-in display tool users can create custom display pages to represent the flow of utilities throughout a building. This could be in the form of a single line diagram or by load group. For example; electricity can be grouped into loads like – lighting, general power, lifts/elevators, HVAC, general fans. Water loads can be grouped into loads like – cooling towers, toilets potable or domestic hot water.
