[TRNSYS-users] Surface Temperature

Elise,

  There are a lot of things that could cause this behavior. If the 
building is sitting on the ground, the most likely problem is that the 
ground temperature under the building is (incorrectly) set to 0C. In any 
case I cannot think of a physical reason why this would happen so my 
guess is that there is an incorrect assumption or connection. If you 
aren't able to find the cause then perhaps your Trnsys distributor can 
assist.

kind regards,

  David
