<DIV>Hi,</DIV>
<DIV>I think the software Helios developed by LBNL would be helpful.</DIV>
<DIV> </DIV>
<DIV>Another suggestion: you can pick up some glazing/window samples from
the envelope library in the help files of eQUEST. I have calculated the
shading coefficient of some devices for the city of Guangzhou, China. If you
like, I can send them to you.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>

<DIV><B>Subject:</B> [Bldg-sim] Window Heat gain - Shading
Coefficient</DIV></DIV></DIV>
<DIV><BR></DIV>
<DIV class=Section1>
<P class=MsoNormal>All,<o:p></o:p></P>

<P class=MsoNormal>I need to calculate shading coefficient of a window glass
with and without the effect of a shading fin. I could not find any software that
does this for me so this is how I’m trying to calculate it: Calculate window
heat gain for both cases from Eplus and then perform a manual calculation to get
shading coefficient of the window. Since the shading coefficient is the ratio of
solar heat gain admitted through the glass as compared to the solar heat gain
admitted through 1/8" clear glass (1/8" clear glass = 1.0 Shading Coefficient)
under similar conditions… so If I simulate the base case as 1/8” clear glass…
and then calculate the ratio.. I should get my result… (?)<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Did anyone of you face this kind of a scenario before? Can
you please shed some light on this?<o:p></o:p></P>
<P class=MsoNormal>Would you know of any tools that does this kind of
simulation?<o:p></o:p></P>
<P class=MsoNormal>Any input is highly appreciated!<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
