Re: [EnergyPlus_Support] Specifying Report Variables

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

"Report Variable, *"  will never sum or group values.  It will always 
report that particular report variable for all instances of that report 
variable.  There are two ways to determine all available key values for 
a given report variable:

1.  Find the report variable in the Input Output Reference and determine 
what specific object type(s) create that report variable.  All names of 
instances of that object(s) will be the key values.

2.  Do a run with * and the csv output file will show all occurences of 
that report variable.  Or you can also look at the top of the eso output 
file which will also list all occurences of that report variable.  Note 
that they may not all be adjacent to each other, so you may need to 
search on the report variable string.

All report variables should have a definition in the output file, but 
there may be a few lurking without one.  DIRECT AIR happens to be one of 
those components without a report variable list and definitions. 

HVAC,Sum,Direct Air Sensible Heating Energy[J]
HVAC,Sum,Direct Air Sensible Cooling Energy[J]
HVAC,Average,Direct Air Sensible Heating Rate[W]
HVAC,Average,Direct Air Sensible Cooling Rate[W]

These all report the sensible heating or cooling delivered to the zone 
through a particular DIRECT AIR terminal unit.  The key values will be 
the names of the DIRECT AIR objects.
