Re: [EnergyPlus_Support] heating and cooling energy consumption

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

Yes, your conclusion is correct.  However, be careful that you select the 
report variables for each component which represent energy consumption rather 
than heating/cooling delivered.  You can confirm this by looking at the mtd 
output file at the various electricity and gas meters (in the lower half of the 
file).  You may find the CUSTOM METER object to be a useful way to combine 
these items.

Also, be sure to use the ABUPS report (report:table:predfined, abups;) as a 
check to make sure you have not left out a component.  For example, the sum of 
your subtotals for residential heating electric energy plus office heating 
electric energy should match the ABUPS value for heating electricity.
