The HAMT model code is making use of EnergyPlus’s
flag that indicates when it is raining. My understanding from the HAMT developer
is that the model formulation is virtually the same as original, 1-d WUFI.

HAMT material properties sources?
As a WUFI user, I have yet to experiment with the
EnergyPlus simulations that include moisture. I have been told that the
implementation of HAMT in EnergyPlus is not as true to WUFI as one may like.
For one thing, there is no rain in EnergyPlus and that greatly impacts some
wall calculations. If properly implemented, I suspect that calculation times
would dramatically increase dramatically. On the other hand, a partial
implementation may give one some moisture buffering. If work slows down, we may
have time to review this further....

The HAMT model is similiar to what is inside seperate software called WUFI. I
don't know for sure if they expose the necessary material data, but it may be
worth trying to extract input data out of WUFI.

Hello everyone,
I am looking for alternative sources of material properties for use with HAMT
simulations within Energy Plus. Annex 24 catalog is apparently out of print and
I am unable to find anything else.
Directions to any other HAMT relevant material that can help us to better
understand will be appreciated.
Thanks in advance!
Fran
