Re: [EnergyPlus_Support] Rare materials

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

EnergyPlus uses constant properties for materials at all 
temperatures.  If this is true within a small percentage for the 
materials you are modeling, then you should get reasonable thermal 
simulation results.  If you are modeling moisture transfer, you may 
run into problems.
