Internal conduction gains issues

Post by danylore »

Dear all,
I've a problem simulating Ashrae loads, in particular I've an abnormal output for internal conduction gains variable. I've have a medium-complex building with some external zones and some internal only-zone. All those zones are adjacent to an external building defined as "adjacent building" in VE. I've read in other topics that "adjacent building" implies an adiabatic condition to internal partition/ceilings but it's not true in my model. If you see this image:

.. I've two zone, one "small-totally-internal" that has, correctly, 0 internal conduction gains (red line) and one room with adjacent building on two side that has some variable internal gains... I don't know why.

Both zones confine under with other thermal zones and above with adjacent building.

Can somebody explain me why I've this abnormal behavior?
Thanks in advance!
