Thanks for your e-mail.

I have sent you a detailed description of the slab floor model that 
interacts with the simple building models. We have another version - 
slightly different that interacts with the Type 56 multi-zone building 
model.  In the version that interacts with the Type 56 model, you give the 
ground model the inside surface temperatures of the walls and the model 
calculates the outer surface temperatures which are then fed back to Type 
56 through a boundary wall input temperature.

The ground conduction models are available for purchase. There are 
currently several available:

1) Slab Model to Interface with Type 56
2) Slab Model to Interface with Simple Building Models
3) Basement Model to Interface with Type 56
4) Basement Model to Interface with Simple Building Models
5) Like Option 1 - But with Pipes for Cooling/Heating/Storage
6) Like Option 2 - But with Pipes for Cooling/Heating/Storage

Eventually these will become part of a new TESS ground model library. But 
for right now we'll sell them individually for $150 US or all 6 for $500. 
They come with documentation, source code, example projects and IISiBat 
proformas. Please let me know if you'd like any additional information on 
these models!

No - to add the new capabilities requires that you add the new models to 
the TRNSYS DLL.  If you do not have a FORTRAN compiler we can perform this 
service for you at no charge - provided you are using the latest version of 
TRNSYS....
