Re: [EnergyPlus_Support] building envelop load



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.
