Qi, As I said in my email to you a few days ago, you can define multiple groups of zones in Type56 that have nothing to do with each other thermally. So while it is true that you can only have one instance of Type56 in your simulation, that Type56 can be used to simulate how ever many separate buildings (or parts of buildings) that you want. As far as defining more than one soil temperature, you simply need to define new ground temperature inputs for the BOUNDARY temperature in each section of the building. Defining non-standard inputs to Type56 is an important, basic operation when working with this model. It would be wise, I think, to study a few of the examples that use Type56 and to look carefully through the 05-MultizoneBuilding manual (particularly the first part that focuses on the use of TRNBuild). You may also benefit from going through the "temperature level control from energy rate control" tutorial that is available from http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm. While the tutorial does not directly deal with setting boundary temperatures, it does show how to manage Type56's inputs and outputs; something you will need to do as well.
