Thank you very much Jim for your suggestion. I will look into it.

The schematic below may be helpful as a means if visualizing what you are creating for an air loop. I started using this in my early attempts to use EnergyPlus and still find it helpful.
- An airloop branch normally contains all of the energy components shown in the top portion of the schematic. I've shown an example "Branch" object below for an air loop. You do not need all of the components; choose those that apply to your system.
- The zone equipment is configured a bit differently, as shown in the bottom part of the schematic. I recommend looking at the example files that are provided with E+ to see which objects are used and how they interact.
- The GUIs such as DesignBuilder and Open Studio / Sketchup make this a lot easier for you to create.

I was using EnergyPlus to model a building that with multiple AHUs, and VAV box with reheat.
I have 3 questions at this point, that might need your assistance.
1. When creating branches, how would define a branchï¼?
As in the attachment of my model, WestAHU1ï¼?would from node â??OSA W1 Inlet" to "W1 Fan Out"a branch or from "W1 out Side Air
Nodeâ?? to "W1 Fan Out" or something else?
So Does in PDF North 12, and West AHU23. will that be same? since West AHU23 just has outside air?
The branch I formed now you can see my idf file, Branch Obj 70,71 72 73. I am not sure if it right.
2. For the ERU(Energy recover unit) in my drawing, I was not able to have the exhaust fan (EF W1, EF W23 or EF N12) in the system. If I have constant volume Fan item the program will not run.
3. If I deleted the fan, the program will run but I do not have a proper SVG diagram generated, is that means the configuration of my system has issues?
In the attachment is the PDF of the section I have question with the system, also I have the CAD drawing for whole system and idf file.
Thank you!
