Re: [EnergyPlus_Support] Moisture transfer

["Michael J. Witte" <mjwitte@xxxxxxxx>]

 1.  EMPD only models moisture storage and release, so it will not model this.  
MTF is intended to model moisture transfer, however the current implementation 
is rather limited due to a single set of linear coefficients when in reality 
the mositure properties are very nonlinear as conditions change.  See the 
cautions in the I/O reference and Engineering Reference in the sections 
regarding moisture material properties.  I do not think that MTF can deal with 
soil as the outside environment.  So, you probably need to find another tool to 
model this moisture transport.

2.  No.  Othersidecoeff has no provision for establishing moisture conditions.

3.  EnergyPlusV1-3-0\DataSets\MoistureMaterials.idf
