I am trying to apply different insulation for external walls and different glazing for windows to lower the energy consumption in my project. The problem is I don`t know how could I define and change the variables in EnergyPlus and JEplus.When I ran the EnergyPlus I only saw XPS as insulation material and when I applied Rock wool-0.04 as an insulation material in JEplus, it was defined as Rock and wool separately. I was wondering how could I access the library in EnergyPlus and define variables in JEplus.By the way, I use DesignBuilder as a simulation tool. Thank you in advance.

Just a quick answer, first you need to have all the construction and the associated material objects in the same IDF file, then you can use jEPlus to apply the constructions to different surfaces. In your case, you shall have XPS and Rock wool materials, and change the construction object to reference the one you want to use.

I am not sure which example to point you to. The one included in the latest jEPlus+EA (v2.1.0) has different materials and constructions as parameters. In any case, it will be necessary to learn how E+ models work before you can use jEPlus effectively.

Thank you so much. The problem is solved by defining the variables in EnergyPlus.
