The energy systems are listed in the Systems pane. You can define what parts of the physical infrastructure to include in the system, and you can define the properties.

You can create a new system by selecting > File > New Energy System or by clicking the Systems pane New Energy System icon.
In the dialog box, type a name and define the environmental settings for designed IT load and outdoor temperature.

You can double-click a system in the list (or right-click and select Configure Energy System) to open it in a separate tab in the editor to configure the system. Multiple systems (maximum 10) can be open at the same time.

In the graphical editor, when you open a new system, there are no components included in the energy system. They all appear grayed out. You can define which components of the physical infrastructure to include in this energy system by right-clicking the components in the diagram and selecting to include / exclude them. The included components are no longer highlighted in gray.

You can delete a system by right-clicking it in the Systems pane and selecting Delete.

Once you have configured power consumption from sensor measurements or estimations, you can see the energy efficiency rating for the energy system on the dashboard.

You can set the calculation interval and environmental properties for a system by right-clicking it in the Systems pane and selecting Properties.

For an overview of all components in the entire physical infrastructure and all power dependencies across the energy systems, you can open the Power Dependency Editor.


The system needs a minimum energy system configuration to provide you with a calculated PUE/DCiE value. An energy system must at least include:

  • Switchgear
  • Energy Efficiency properties set on the switchgear and PDU
  • A PDU connected to the switchgear
  • A script configured on the PDU
  • IT load properties set to include measured calculation source
  • Derate Capacity must be >0

Configuring an energy system
Configure the components of the energy system to ensure the configuration accurately reflects the live physical infrastructure of the system.

  1. Click the Systems pane New Energy System icon
    and type a name and define the environmental settings.
  2. Double-click an energy system in Systems to open it in the editor.
  3. To include components in an energy system:
    1. Right-click a grayed out component in the diagram and select Include in energy system.
    2. Repeat this for all the components that you want to include.
      When a component has been configured to be included in the energy system, it will no longer be grayed out.
    3. If you regret including a component, right-click it and select Exclude from energy system.
  4. Configure IT load, infiltration, lighting, and ventilation subsystems by clicking the icons at the bottom of the energy system, or by right-clicking the energy system in the Systems pane.
  5. At any time, right-click a component to see the properties.
  6. In the Scripts pane, create scripts to include measurements in the energy system's PUE/DCiE calculation.
  7. Associate the created scripts with the components to indicate which scripted values to include for which components in the diagram by right-clicking the components in the diagram and selecting > Associate Scripts > Folder name > Script name.
    You can see the PUE/DCiE, CO2 emission and cost results of the configuration expressed as graphs published to the Energy Efficiency Dashboard available when typing the server's IP address into a Web browser.
