[TRNSYS-users] Ground coupling building

[David BRADLEY]

Yossef,

  I would recommend that you look online for some accepted methods for 
dealing with ground coupling. I have seen the method that you suggest 
used but I have not seen any technical papers that present its results 
against an analytical solution or against measurements.

  The simplest method of which I am aware is the "f factor" approach. 
There is also a Type in the standard library (Type49) that couples a 
building to the ground through a slab. Another (Type1267) is available 
as an add-on for more complex building geometries that cannot be handled 
by Type49.

kind regards,

  David
