Hi Farraji,

there are different approaches to this in TRNSYS, each with 
different advantages/drawbacks. The enclosed slides from 
our TRNSYS course summarize the most frequently used 
solutions.  

A variation of using the boundary wall method with modified 
ground temperature is to calculate the ground temperature 
with Jeff Thornton's Type 164 (or with some user-defined 
equation). See also the TESS website for more information 
about the non-standard types: http://www.tess-inc.com/  

(Type 164 is on this page: http://www.tess-
inc.com/tess/trnsys/tessutil.htm)  

Hope this helps,

Werner
