[EnergyPlus_Support] Environmental Impact Factors & Fuel Factors

["fortierengineering" <fortierengineering@xxxxxxxxx>]

I have modeled a building in Pennsylvania and to start I have used the 
electricity and natural gas fuel factors found in the data sets as well 
as the Environmental Impact Factors to determine the emissions 
contributions from this building.

When I spoke with the local electricity company they advised me that 
the transmission losses for this location were lower than the state 
average.  They did not have information reguarding the exact g/J of 
emission break down.

I cannot figure out what field controls the electricity transmission 
losses.  

I thought it was the "J per measured unit factor" or the "source energy 
factor", but changing either of these fields does not affect any of the 
emission factors (ran the simulation at 1.827, then 1, then 10 and the 
emission totals turned out exactly the same).

What are these two fields used for if they have no effect on the final 
data, and what is the best way to express a reduction in transmission 
losses?

Thank you,

Joseph Lewis
