I am doing EEM modeling, with both gas and electric effects on a multi family
unit in Los Angeles.
One EEM is a lighting reduction. Another is weather stripping, which reduces
infiltration.
I add up the EEMs individually and get a gas savings (negative from the lighting
reduction obviously). I add them together in a COMBO run (where they
interact) and the gas savings goes UP !!
WHY !!!!
