Re: [EnergyPlus_Support] Need Help For Making IDF Files Dynamic
I would suggest that if all the information is changing that you use the Parametrics objects to change the name of the material, for example, if you left both of those Material objects in your file, you can change the reference by including:
Parametric:SetValueForRun,
$roofDeck,
Aluminum_Roof_L0,
MetalDeck_Insulated_L0;
Construction,
ROOF-1, !- Name
=$roofDeck, !- Outside Layer
BR01, !- Layer 2
IN46, !- Layer 3
WD01; !- Layer 4
Obviously, you would need to modify the Construction object to match your project.
The InputOutputReference section titled "Parametric Objects" describes the features more.

I tried to use Parametrics objects but still do not know how to change the complete information. For example, in one of the IDF files, I have the following information.
