You can read more about the environmental impact factors in EnergyPlus and the fuel factors as well as all the possible outputs (seems to be associated with site energy) from the I/O reference. There are several ways to report the outputs, I will mention some:
- Through the standard annual report:
In the
Output:Table:SummaryReport
object, make sure to add the
predefined reports "AllSummary" or
specifically "EnergyMeters" and
look under the energy meters
subsection after you run the
simulation. - Through
Output:Variable
and Output:Meter
objects:
You can check the Report Data
Dictionary (.rdd) and Meter Data
Dictionary (.mdd) files to see all
possible variables and meters that
you can report based on your model.
You can search for the keywords
"CO2" or "emissions" and select the
desired variables/Meters.
Here is an example of using both output variable and output meters, both should show the same results (of course you can change the reporting frequency):
Output:Variable,
*, !- Key Value
Environmental Impact NaturalGas CO2 Emissions Mass , !- Variable Name
Monthly; !- Reporting Frequency
Output:Variable,
*, !- Key Value
Environmental Impact Electricity CO2 Emissions Mass , !- Variable Name
Monthly; !- Reporting Frequency
Output:Meter,
ElectricEmissions:CO2 , !- Key Name
Monthly; !- Reporting Frequency
Output:Meter,
