Re: [EnergyPlus_Support] building envelop load

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

The building envlope load is not readily reportable with current output 
options.  In the Input Output Reference, search for the report variables and 
find the definitions.  Zone Window Heat Loss/Gain already include the 
transmitted solar.  And Zone Opaque Surface Inside Face Conduction is only 
meaningful when summed over longer periods of time (at least a day, better a 
week or month) because of thermal storage in the wall construction.
