Re: [TRNSYS-users] Ground coupling building



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

Hi,
I'm modelling a building, and for the ground coupling I'm using Type77 (Kusuda correlation) with the groud thermal properties, I'm also adding 0.8m of soil into the ground floor layers + a masless layer with the thermal resistance of soil (to reach 2m deep) with a timebase of 3. Is this a correct way to model the ground coupling?
Thank you
