Re: [EnergyPlus_Support] Question about materials

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

Material:Regular-R has no thermal mass, so there is no storage of heat in the 
surface materials.  It is rarely proper to have an building which is entirely 
constructed of this type of material.  Material:Regular does have thermal mass. 
 So you should see some time lag in the building response to outside weather 
when using Material:Regular.
