Thank you so much, Linda!
Looks just like what I needed.

You want these:

Zone,Sum,Zone Window Heat Gain Energy [J]
Zone,Sum,Zone Window Heat Loss Energy [J]
or
Zone,Sum,Window Heat Gain Energy [J]
Zone,Sum,Window Heat Loss Energy [J]


Custom meters can also only take on summed variables.

I've got a problem with some averaged Output:Variables.
I'm trying to get a monthly report of the total Window Heat Gain for a FenestrationSurface:Detailed of type "Window" so I try to:

Output:Variable,
   Sample Window,       !- key value
   Window Heat Loss,  !- variable name
   Monthly,                     !- reporting frequency
   ;                                   !- schedule name

But since this variable is (quote from .rdd):

Output:Variable,*,Window Heat Gain,monthly; !- Zone Average [W]

I cannot get a total (sum) for the whole month, only average.

So my question(s) are:
1) Why isn't there a Sum variation of this variable?

2) How can I get the sum version? I know I could manually multiply the average value by the number of hours but this requires more work and scripting..

3) I tried specifying a Custom:Meter which includes this specific Output:Variable but couldn't get it to sum over a month (Meter:Cumulative also didn't seem to work with it). Another solution is to get the needed number of hours from a Output:Table:TimeBins report but this means lots of additional generation of output tables..
