</P>
<P><FONT SIZE=2 FACE="Arial">I've been looking through a model in EnergyPro that has a SHGC</FONT><FONT SIZE=1 FACE="Arial">c</FONT><FONT SIZE=2 FACE="Arial"> of 0.99 entered into the baseline model, because the existing office baseline building is old single-pane 1/8" glazing (window:wall ratio is about 30%). However, a more reasonable assumption here, based on the non-residential Oregon code compliance manual would be SHGC</FONT><FONT SIZE=1 FACE="Arial">c</FONT><FONT SIZE=2 FACE="Arial"> =0.86. The issue I'm having is that I can't re-run the model so I have no way of telling how this might impact energy use. My hunch is that this difference in SHGC would have mimimal affect on the energy consumption. Any thoughts? </FONT></P>
<P><FONT SIZE=2 FACE="Arial">I've also been told that while the EnergyPro input for glazing characteristics is SHGC, EnergyPro actually treats this input as a Shading Coefficient in the calculations. So, if this is the case then an input of 0.99 shading coefficient would actually calculate to be a SHGC of 0.86, and would be the correct input. Does anyone know if this is true?</FONT></P>
