Re: [TRNSYS-users] Temperature difference



David,
What would be the best assumption to control the ground temperature?

Michele,

  it is a bit hard to see the picture but it looks to me as though the TGROUND input is unconnected and set to an initial value of 0. That means that your building thinks that the ground temperature is constantly 0C.

kind regards,

 David

Hi David
I checked for links between the TGround and it is not linked with anything. How this can be? I used the multizone template and entered the weather from Meteonorm files.

Michele,

Check your assumptions about ground coupling. It sounds as though perhaps the ground temperature beneath the church is set to something unrealistically low.

kind regards,

Hi im modeling a church modeled as an atrium. But the lower part of the church is showing really low temperatures, in summer even difference of 10 degrees difference from the outside. What could be the reason? as the upper parts of the church shows more a realistic results
