Do your initial run and then copy the calculated size for each system objects rather than autosize.
For example:
ZoneHVAC:Baseboard:Convective:Electric,
Main Zone Baseboard,
System Availability Schedule,
Autosize,
ß
0.97;
ZoneHVAC:Baseboard:Convective:Electric,
Main Zone Baseboard,
System Availability Schedule,
8000,
ß
0.97;

Subject: [EnergyPlus_Support] Auto-size and user values
Dear Group,
I was wondering how a user can simulate a system based on actual sizing parameters, avoiding the implementation of auto-sizing during a simulation. Particularly, as I read in documentation and try to apply, a HVAC system can not be simulated without auto-sizing.
However, for my case as I will need to make changes on the building envelope I need to run simulations without changing the parameters of the system for each individual simulation case (The system is auto-sized on the particular changes that I made on the building
envelope).
So, does anybody know how can I avoid the auto-size part of the simulation and thus, run an actual system for my simulations.
Thank you in advance for any response to my message
George G.
