I am running a parametric analysis using prototypes that are autosizing most HVAC components. How can I run this prototype once, to obtain the values auto-calculated, and then fix those values for subsequent runs. I do not want each run to autosize the HVAC system, but to use only the autosized values from the 1st run.
@Jeremy Thanks for your response! I am using jEPlus to run the parametric analysis. Also, I am writing a python code right now using eppy, but I'm struggling to extract the sized values from the .eio file and to match the field names from the .eio files to the actual field names in the .idf file. Any recommendations on how you did it with python? Thank you!!
I did something similar some time back to fix the VAV size. I don't know if there is an easier way to do it. You can find the designed or sized outputs in .eio file that is generated after the first simulation. From this .eio file look for the right table for the right sized variable. Replace the autosize variable in .idf file with the designed value from the .eio file from the earlier simulation.

Just curious if anything may have changed in the last three years on the E+ side? The Eppy method is feasible, but not ideal, and this would be a really useful native feature of E+.
