What System/Loop Level Controls are Required?

Required Loop Level Controls

The following are required controls for a Simergy and EnergyPlus simulation to run:

Air Loops - An Availability Manager is required
- Note: for Water Loops the Availability Manager is optional
Water Loops - A Plant Operation Scheme (also referred to as a Plant Equipment Operation Scheme) is required for each water loop (HW, CW, MxW or CHW) that is part of the project.

What are System Level Controls (also referred to as Loop Level Controls)?

Some controllers within EnergyPlus provide broader control of loops and plants, and therefore do not fit directly within the ‘loop diagrams’, because they are related to multiple components versus a single component and they represent a higher level of control.

Simergy capabilities for System/Loop Level parameters and controls are located in both the Create/Edit and Diagram Workspaces for Air and Water Loops.

A view of the Water Loop Create/Edit Workspace for a Chilled Water Loop. The System Level parameters are located in the table at the bottom.

A view of the Water Loop Diagram Workspace for a Hot Water Loop. The Loop Level Controls for the types Plant Operation Schemes, Availability Manager and Demand Manager are located at the bottom. Selecting the properties button for each will access a dialog box allowing more detailed information to be entered for each type. See System Level Controls.
