Re: [EnergyPlus_Support] Conflicting output reports



1.  In the zone sizing section of the eio output, the peak temperature and 
humidity are the outdoor conditions at which the peak zone load occurs.

2.  "Rated Total Cooling Capacity" as defined in the Input Output Reference is 
the capacity at ARI rating conditions.  Actual cooling output will vary with 
changing outdoor and entering coil conditions.  None of the Report Variable 
names have the term "capacity" in them.  Definitions of report variable names 
may be found in the Input Output Reference; search for the variable name.
