[TRNSYS-users] Thermal bridges !

[Alastair McDowell]

Hi Issmail,

Have a read of section 5.2.10.8.4 in the Type56 user manual.

“To consider the effects of thermal bridging on the thermal behavior (heat losses) and other
physics (condensation and mold) of walls, the description of this effect was included in the
building description. Thermal loss rates are found in thermal bridge (coldbridge) catalogues, and
are normally defined in W/m length of the coldbridge or, in TRNSYS units, in kJ/h m. Walltypes
for coldbridges are special coldbridge types defined with a resistance and therefore are
considered to be without thermal capacitance.”

In TRNBuild, go to the window that specifies all the walls and windows of a zone. Below the 'Walls' pane, click on Add.  Select from the pull-down menu to the right of 'wall type' the option 'Coldbrigde'.  TRNBuild will open a window asking you for the required parameters.

​Dear colleagues, hope you all fine !

Is there any way to model a thermal bridge in TRNSYS/TRNBuild ?
thank you

Regards,
ISSMAIL.​
