I'm calculating the zone mean internal temperature, but i think the zones are not transmitting heat.
For example: The roof is on 56C and his boundary zone its 28C...
Did you can help solve this?
Thank you!

I'm going to assume this is what you "deleted":
BuildingSurface:Detailed,
TETOZO, !- Name
Ceiling, !- Surface Type
Internal Ceiling, !- Construction Name
zonaocupada, !- Zone Name
Zone, !- Outside Boundary Condition
ATICO, !- Outside Boundary Condition Object
that is, you deleted a similar surface in the ATICO zone.
Read about this object -- when you use Zone as the Outside Boundary
Condition -- the program automatically creates the surface in that zone
to affect the interzone heat transfer.
Which is also why I directed you to look at the output (in the .eio
file) of the Output:Surfaces:List,Details report. You should have seen
duplicate surfaces in the zones for this object.
I cannot answer your other questions at this time except to direct you
to looking at Ground Heat Transfer (in the Auxiliary Programs document)
and to make sure that your floor in the raised building (if I'm
understanding what you are saying) has Outdoors as the boundary
condition but, likely, will not be Sun Exposed. It would be exposed to
wind.
I may have time to look in detail at your files later but equally
someone else on the helpdesk may as well.
