RE: [EnergyPlus_Support] parametric simulations for different materials
To me more specific, you would have:
!- Parameter Name
!- Value for run 1
!- Value for run 2
!- Value for run 3
!- Value for run 4
And, I believe whereever you want to use it:

Thank you James,
I agree with you. In fact i just took a bad example, but I meant : how
can I run parametric simulations for different constructions. I want to
know if EP can grab the constructions as a whole or can EP only simulate
particular values (U or thicknesses) ?

Insulation that is contained within a wall generally has low mass, at
least low enough not to significantly affect the mass-influenced time lag
through the wall system. For that reason, I doubt that you will see
a difference between modeling specific materials and just specifying
different conductance values.
I think you could easily run any conductance value using the parametric
processor, just as you already did for thickness.

Thank you all,
I followed your advise and finally succeed to run parametric runs with
What I did was for a variety if insulation thicknesses (2,5,7,10,12
Now, I want to try something else.
How can I run a parametric simulations of different insulation

Subject: Re: [EnergyPlus_Support] Run a series of simulations
A recent addition to EnergyPlus utiltiies -- the Parameteric

ParametricInsulation-5ZoneAirCooled.idf is in the included
Objects to look for are:
the Parametric Preprocessor is documented in the Auxiliary Programs
There are at least two other example files that use these.

Two links from the installation:
Example Files Summary Sheet - highlights each example file
Example Files Link to Objects - shows the first three example files
that many exist) that have a particular object.
You can also accomplish parametric runs with the EPMacro preprocessor.
EP-Launch can be used in this method to run a user set number of
