[Equest-users] Source VS site EUI

[John Aulbach]

The eQuest SITE Energy is that which is measured at the meter, that which you are billed. SOURCE Energy is an estimate of what the energy is at the power plant or the gas works. I believe eQuest (DOE-2) has a multiplier of three on it, so 1 million kWh SITE becomes 3 million kWh SOURCE.
Energy Star probably has its OWN multiplier for Carbon footprint, so use your bills (Site Energy)---unless it has already calculated SOURCE energy for you. SOURCE energy will be the one stating how much of a power plant use YOU cause.
Hope that helps.

I am in process of calculating the carbon foot print of my building. I have the values for electricity and fossil fuel EUIs.   I also have a report from energy star (https://portfoliomanager.energystar.gov/pdf/reference/Emissions.pdf ) that explain how to calculate the carbon footprint of the building. however, I am not sure that I need to use source EUI in my calculation or site EUI.    Can you please explain? Thanks, Fred
