Re: [EnergyPlus_Support] Contaminants information?

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

Please see "Report Environmental Impact Factors" in the Input Output Reference  
(starting on p. 1351, pdf p. 1390) and the Engineering Reference (starting on 
p. 817, pdf p. 853).  These report variables and meters simply take the 
environmental factors input by the user for electricty and fuels and multiply 
them by the site consumption of each particular energy source.  Equations are 
currently not in the documentation, but they are all similar to the following.

For example, a building purchases electricity and natural gas, and has no on-
site power generation


CO2:Facility = (C02EmissionFactorForElectricity * Electricity:Facility) + 
(C02EmissionFactorForGas * Gas:Facility)

Where 

Electricity:Facility and Gas:Facility = the consumption meters for electricity 
and natural gas

C02EmissionFactorForElectricity and C02EmissionFactorForGas = the "CO2 emission 
factor" field in the Fuel Factors object.

There are datasets of fuel factors in the Datasets folder: Electricity USA 
Environmental Impact Factors.idf and Fossil Fuel Environmental Impact 
Factors.idf
