[EnergyPlus_Support] inside surfaces
Hello again,
I am trying to simulate a generic office in the middle of a building.
For this I used "OtherZoneSurface" for all the interior surfaces
(including roof and floor) and used each interior surface as exterior
environment for itself, since all the building would be conditioned
at approximately the same temperature. Doing this I got very close
inside and outside temperatures for these surfaces. However I have
problems understanding a couple of results:
1-Although the I-O temperatures are quite close, they`re not equal as
I would expect. Is this normal?
2-The conduction through these surfaces (which I would like to be
zero) is quite high compared to exterior surfaces. I am using "Opaque
Surface Inside Face Conduction", and the relation between deltaT, U-
value and conduction seems inconsistent. For instance, a typical
temperature difference for interior surface is between .3C and 1.3C,
for exterior surfaces is up to 12C. However, the conduction remains
in the same order of magnitude, even if I choose a higher U-value for
the exterior wall. How can this be possible?
3-I am aware that a solution would be to define these surfaces as
internal mass, and not as heat transfer, but I am concerned with the
effects on radiation and daylighting results, that if I omit floor
and roof might change. Is this correct?
Thank you very much in advance,
Santiago.
PS: taking the opportunity, thank you Mr. Witte for your help with my
last question.
