[TRNSYS-users] Humidity transfer through walls

[David BRADLEY]

Damien,
  You are correct that moisture transfer through walls is not accounted 
for. If you implement TRNFlow in your Type56 model (or if you couple 
Type56 with CONTAM/Type97) then you will see some of the effect of 
moisture transport as air infiltrates into the space through openings 
and by air leakage through the building materials. I have not seen any 
studies that address the issue of the relative magnitude of moisture 
transport through materials as compared to being a biproduct of 
infiltration.
Regards,
  David
