There is not really any answer to your question. The way that you zone a building depends on what you want to know from your simulation. If you are combining a thermal and airflow simulation of the building then you might treat each room as its own zone. If you have a very large building (such as a highrise) then you might treat every floor as a zone or perhaps you might divide each floor into a core zone and as many perimeter zones as there are solar orientations. In between those two extremes, it is not uncommon to choose thermal zones that correspond to the HVAC zones of the building (areas that are controlled by one thermostat).
If you are using Trnsys18 there is an extensive tutorial in the .\Trnsys18\Documentation\ folder that will teach you what you need to know to model buildings. If you have Trnsys17 then there is a less extensive but still useful tutorial in ..\Trnsys17\Documentation\A4_3DBuildingTutorial.pdf
kind regards,
