How can I configure jEPlus to modify the insulation thickness in TRNSYS
I’m currently working on a project involving TRNSYS and jEPlus for a parametric study, I’m trying to adjust the insulation thickness in the roof floor and walls but I’m having trouble because the parameter doesn’t seem to be directly specified in the .dck file.I was wondering if you could provide some guidance on how to handle this issue.
Hi, would you be able to show me how insulation thickness is defined in your trnsys model?
In TRNSYS, the details of construction materials, including insulation thickness, are specified in the b18 file. For instance, you can find the insulation thickness listed in the b18 file like this: CONSTRUCTION GROUND LAYERS = FLOOR STONE SILENCE CONCRETE INSUL THICKNESS= 0.005 0.06 0.04 0.24 0.08
ABS-FRONT= 0.8 : ABS-BACK= 0.4
EPS-FRONT= 0.9 : EPS-BACK= 0.9
HFRONT = 11 : HBACK= 999 However, it's worth noting that jEPlus primarily works with the .dck file for its operations. Consequently, if I need to adjust these details, I would need to refer to the .b18 file.
Hmm, it sounds like it is time to update jEPlus. Can you send me the full set of input files of your model? In the meantime, a workaround may be to create a bunch of b18 files with different thicknesses and use jEPlus to change the reference - a bit dumb and only works when you have only one or two variables in b18.
