Using THERM values at two components intersection

Post by Robert Albano » Fri Mar 27, 2015 9:57 am -1100

In WUFI Passive how does one use a LBL THERM value for the intersection of two components? The use case is between wall and ceiling components. Is there a tutorial on this? I have the THERM value but need to know how to use it in WUFI Passive.

on the static side, you can add the linear thermal transmittance and the lenght of the intersection in "Thermal bridges".

on the dynamic side, there is no direct input for this. However, you can add a "3D-Object" calculating the dynamic thermal behavior of a intersection by regarding the simulated zone climate http://www.wufi-wiki.com/mediawiki/inde ... 3D-Objects
or a workaround is to add the calculated heat loss or gain from LBL THERM from an external text (http://www.wufi-wiki.com/mediawiki/inde ... sured_Data) file as internal load. But then you have to sum all the heat and moisture internal loads, and thermal bridge losses for a zone within this text file.
