Hi,

I want to use Archsim to conduct energy analysis. I used the face component to include all the surfaces of the thermal zone. See attached pic. 

I need to set the interior walls and the floor as adiabatic but I see only this list of construction materials. No adiabatic option to select. Also, the construction tab doesn't show this option.  Can you help me.

Regards,

Sahar

there is a separate object that is used to specify adiabatic faces -> BoundaryCondition Component.

Hope this helps

Thanks Timur so much.

In case this helps to clarify for others, when you have adiabatic and ground contact objects, you have to create thermal plane objects for them AND tag them with the BC components for ground or adiabatic.

This may seem like you are adding the same object twice to your model, however you can double check the EnergyPlus .idf file to see that these two grasshopper inputs become a single object with the assembly type specified and the outdoor/adiabatic boundary condition, as opposed to 'outdoors.' You can check this by opening the .idf for your simulation using the IDF Editor, which should be part of your EnergyPlus install.

If you have any doubt your geometry is being interpretted correctly, knowing your way around the IDF Editor can be VERY helpful because you can check other outputs, such as # of faces, zone volume, assembly designations, etc.


Hi Michael,

Thanks a lot for this. I checked the IDF editor and it is really useful!
