Re: [EnergyPlus_Support] about building's thermal loads

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

Thermal loads are not meaningful unless the inside space temperature is 
maintained at the desired level.  The only way to do this is to use Purchased 
Air (as explained in the previous response) which will report the sensible 
heating and/or cooling load required to maintain the specified temperature(s).  
I presume that you are trying to understand the effects of various envelope 
design changes?  If you wish to let the space temperature float, then perhaps 
you should use average, maximum, and minimum zone temperatures as a measure of 
envelope performance.  For such a study, you must also consider the free 
cooling that ventilation air can provide by including INFILTRATION or 
VENTILATION or the results may lead to conclusions such as more insulation is a 
bad thing.
