Hi All,

I recently did a model where I had the same system in both base and
proposed but I changed the R-Value from 4 (base) to 20 (proposed). I also
changed the window U-value from .80 (base) to .35 (proposed). After I did
the run, I saw only a 5% savings between the heating and cooling use in the
model. When I looked at the loads I saw the base had twice as much cooling
and heating load than the proposed. Does any know why the energy savings
would only be 5% when you have a huge difference between the cooling and
heating loads?

Thanks,

Lee
