Re: [EnergyPlus_Support] Partitions - possibilities for new outputs?

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

It is a valid suggestion.  We will consider it.  But I must admit, it could 
become difficult to understand the true maining of some of these.  Also, I 
would suggest possibly two other categories - ground environment and other 
environment (othersidecoefficients or other special outside boundary 
conditions).
