Re: [EnergyPlus_Support] upload edificioX.idf file

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

A major problem with this run is that all of the non-window surfaces are made
up of MATERIAL:REGULAR-R, so there is no thermal mass in this building.  This
can cause an unstable solution resulting in a temperature out of bounds error.
Use MATERIAL:REGULAR for all material types except very light insulation
layers.  This should solve the problem.
