That is correct it is a 4 story residential building. I did a parametric run were I changed the Air Chang per hour and U-values for the windows and wall. I only saw a five percent energy savings when I thought with such a drastic change (Wall R value from 4 to 30), the difference would be much better. I have attached the file as a rar.<br>

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?<br><br>Thanks,<br><br>Lee<br></blockquote></div><br></div></div></div>
