to check, but since there’s a total of 3% change, you might check the difference
between space cooling and heating. The difference might be counteracting

<p class=MsoNormal><span style='font-size:12.0pt'>I am doing a model for a two
story office building with the windows making up approximately 30% of the
building’s exterior. My goal is to find what type of energy savings the
owner can expect by replacing all the existing single pane windows with double
pane, low e windows. When I change the window type to a double pane low-e
window I am seeing savings that are very small, around 3% of the total building
kWh.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:12.0pt'>For reference, the buildings
HVAC system consists of two air handlers (one per floor) ducted to a VAV system
with hot water reheat. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:12.0pt'>Has anyone else tried to do
this type of comparison and if so what type of energy savings did you find? I
have attached my model pd2 and inp files for reference. Thanks in advance for
any information.<o:p></o:p></span></p>
