Re: [EnergyPlus_Support] Measuring energy input to the rooms



The Zone/Sys Sensible Cooling Rate and Zone/Sys Sensible Heating Rate variables tell you how much energy is entering the zone through the zone inlet nodes. These will be non-zero if air enters the zone and that air had different conditions (T and RH) than the zone.

Hello,

I am currently trying to measure from the amount of energy entering/leaving  in the rooms through the heating system.
I have found out that the  
Output:Variable,*,Zone/Sys Sensible Cooling Rate,hourly; !- HVAC Average [W] might do the trick but I now noticed something that makes me wonder.

I am currently using the ASHRAE standard commercial building model MediumOffice (location, Baltimore). It can be found there. I enclose a copy that i translated to version 7.2 of E+. This building has 3 stories with 3x5 zones + 3 plenums, where the return air paths are located. There is no terminal unit in the plenums. However, the record of Zone/Sys Sensible Cooling Rate for the plenums is non zero, but it is not clear for me where this energy is suppose
