hi
I am studying about hygrothermal behavior of roof.
How can i model snow effects on a roof by WUFI?
Thanks

hi Thomas
first of all thanks for your help.
based on some papers and field measurements,I found out that surface temperature of roof during snow covering is around 0°C .and i want to use this temperature to model it to see effect of snow on hygrothermal behavior of roof.
so how can i define 0°C as a roof surface temperature when we have precipitation while outside temperature is lower than 0°C (snow) .
thanks

Hello Malimog,
you have to generate a new climate file. For that use the xls-sheet CreateClimateFile.xls in your tools folder. Export the temperature settings on the surface of your roof and set the outside temperature to 0°C during the time the temperature is 0° or lower. Easiest way will be to create a file only with surface temperature and the existing outside humidity. Then you use that file for calculating the roof again. For the heat transfer resistance use 0.
Hope that helps,
Christian
