Hi everyone. I’m trying to implement some papers that control a few parameters during runtime. I’m using Gym-Eplus to vary the values but I’m not sure if the following can actually be controlled.
- How can we control the frequency of a VFD during runtime using an actuator? (In Hertz)
- Is the Return Air Outlet’s Setpoint Temperature similar to what is observed as Return Air Temperature Setpoint in BMS systems?
- How can we vary the Fresh Air Damper’s opening percentage in a chiller system during runtime using an actuator?
- How can we vary the chilled water valve opening percentage to an AHU system during runtime using an actuator?
I couldn’t find any relevant actuators in the .edd file created.

EnergyPlus does not model the physical process of dampers, valves or VFD directly at the component level. You have to look at other tools such as Modelica Buildings Library.
Dear Doctor
"The Energy Management System (EMS) is one of the high-level control methods available in EnergyPlus. An EMS is able to access a wide variety of sensor data and use this data to direct various types of control actions. The concept is to emulate, inside EnergyPlus, the types of controls possible with the digital energy management systems used in real buildings.
In the hierarchy of EnergyPlus controls, the EMS module is a high-level, generalized, supervisory control for building systems. The EMS replicates the functionality of many of the existing high-level control objects in EnergyPlus. Similar to the AvailabilityManager objects, the EMS can turn on and off pumps and fans. Similar to the DemandManager objects, the EMS can turn on and off lights and electric equipment, change the set points on zone thermostats, and dispatch on-site generation. Similar to the SetpointManager objects, the EMS can change the set points on system nodes. Similar to the PlantEquipmentOperation objects, the EMS can turn on and off supply-side heating, cooling, and heat rejection equipment, i.e., boilers, chillers, cooling towers, etc. Similar to the ElectricLoadCenter:Distribution, the EMS can turn on and off on-site generation equipment.
A separate document called Application Guide for EMS contains much more information on how to use the EMS. The EMS uses the EnergyPlus Runtime Language (Erl) for custom programming of control routines."
