Where can I find the contributing variables to Electricity: Facility in ESO file. I want to get the breakup zone-wise. How to know the contributing variable to this aggregate and even breakup zone wise. Your suggestion will let me confirm my understanding and rule out any errors in aggregation. I have 4 Heat pumps for 7 thermal zones and I want to compare my zone wise energy use with experimental data.

If you look in the <filename>.mtd file you will see the meter details which contains what you are looking for. It is documented at:

http://bigladdersoftware.com/epx/docs...

And click on the link for "eplusout.mtd"

(The link directly to that portion did not seem to work when I tried it).

It is described as:

The meter details file consists of two parts:

  • For report variables that are on meters, it shows all the meters that the report variable is on. In the following example, “Meters for” , is shown and then the meters that accumulate the value of that variable as a “meter”.

  • For each meter, the report variables that make up that meter are shown. In the following example, “For Meter=” , “contents are:” and then each variable that occurs on that “meter” are shown.

I think what you want is in the second half. Unfortunately, the list of output variables that are contained in Electricity:Facility is usually very long, often dozens or hundreds of variables.

To include them in the ESO file, each one would need an Output:Variable object.

I have the .mtd file with 1400 lines, the last section do have For Meter=Electricity:HVAC [J], ResourceType=Electricity, Group=HVAC, contents are: VRF ZONE TERMINAL FAN:Fan Electric Energy VRF ZONE TERMINAL FAN 4:Fan Electric Energy VRF ZONE TERMINAL FAN 5:Fan Electric Energy VRF ZONE TERMINAL FAN 1:Fan Electric Energy VRF ZONE TERMINAL FAN 6:Fan Electric Energy VRF ZONE TERMINAL FAN 2:Fan Electric Energy

However, these variable are not in ESO as results, How do I go about including these. As they provide me the zone-wise energy break, which I need to compare with system wise.

You'll need to add an Output:Variable object for each variable you want to see in the ESO.

Yes @Jamie Bull , that is my question . How to add in Openstudio additional Output:Variable objects.

Ah, I see. Sorry, I don't use OpenStudio - I was answering for EnergyPlus.
