Hello there!

I have a building model which has 4 chillers in the cooling plant. In idf file I want to apply chiller sequencing according to the chiller electricity consumption (power-based control). I have an experimental data from the last summer from 4 chillers indicating chiller energy consumption and cooling load provided by each chiller. Do you have any idea how I can apply this method in idf file?

Can you see a pattern in the chiller electricity consumption? Something that could tell you what the control sequence might be, eg if load is > X Watts, then chiller 1 only, if load > Y, chiller 1 & 2, etc?

Yes, I have a trend for that showing me the control sequence of chillers according to the chiller energy consumption and cooling load provided by each chiller? I just want to apply these sequence on the idf file!

Use a PlantEquipmentOperation:CoolingLoad to define your ranges of equipment operating between ranges of cooling load. Plenty of example files show how to use the object, cf ElectricEIRChiller.idf for example

Thanks Julien for providing the response!

Moving it an answer for good housekeeping then.

You can tell me Where is this file ElectricEIRChiller.idf and PlantequipmentOperation:coolingload. Please help me?

In the EnergyPlus install folder, under ExampleFIles folder, eg: C:\EnergyPlus-23-1-0\ExampleFiles\ElectricEIRChiller.idf. Also available online at NREL/EnergyPlus if you want.

Thank @Juilien but I am using Sketchup/Openstudio version 3.2.1 and I will have to install Energylus and is there any other way? Thank you

Specifically for 3.2.1, the version of E+ is 9.5.0, so just use https://github.com/NREL/EnergyPlus/bl...
