Re: [EnergyPlus_Support] About Ground Temperatures

By the way, the Slab program is really for conditioned spaces.

What you may wish to do is look at the "other 
side coefficients" model.  This is described in 
the IOref as well as the example file 
GroundTempOSCCompactSched.idf  Another feature is 
to have a core and perimeter set of temperatures 
-- that is not shown in the example files but can 
be done using a "door" in the floor with one set 
of temperatures where the slab floor (perimeter) 
sees a different set.  Some of this is also 
described in the Auxiliary Programs document on Ground Heat Transfer.

Here you would set your slab as a surface that 
sees temperatures on the other side that may be 
more realistic for you.  You would still need to 
estimate the temperatures used but you may be 
able to "play" with those temperatures more 
easily and get your measured(?) temperatures inside more realistically.

Ground heat transfer is a real bugaboo for 
simulation -- one can make the results be almost 
anything you want (or don't want) by setting 
ground temperatures too low or too high.
