Re: [EnergyPlus_Support] Plant and System changes during macro runs

My apologies for the slow response . . .

I am not exactly sure what you are asking.  Depending on the system type, you 
may be able to use Compact HVAC objects to simplify creating the base file.  
But ultimately, you will need to create the objects that describe the 
alternative systems.  You can use ##if blocks to conditionally activate the 
different sections of input to automatically switch from one system alternative 
to another.
