[TRNSYS-users] How to sonstruct a dynamic building model in trnsys

[David BRADLEY]

Qi,
  To add to what Jochen wrote, the zones in your Type56 model do not 
have to have any direct thermal contact with each other. If you were to 
create a zone for the platform, a zone for the concourse and a zone for 
the entrance but have no ADJACENT walls in the model then there is no 
direct thermal contact between the parts of the building. In order to 
simulate the indirect contact (contact through the soil) you need to 
implement BOUNDARY walls in each of the three sections of your model 
these BOUNDARY walls will be in direct thermal contact with a soil 
model. For the soil model I would recommend that you start off simply 
assuming that the soil is a known temperature that is not affected by 
what happens in the metro. This will get the model running and allow you 
to test it. Once you have the building and its thermal zones set up then 
you can implement the Type1267 (Tess Ground Coupling - 
http://trnsys.com/tess-libraries/individual-components.php) in order to 
model the dynamic impact of the soil.
Kind regards,
  David
