A correction factor for the SHGC could be calculated, but this factor would change significantly depending on geographic location (sun angles), and would not give you accurate results at an hourly level (accurate for annual only). If you're trying to avoid modeling all of the shades, you could pick one typical window for each exposure to model, and apply those results to all of them, but I'd recommend against that. <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>This is when modeling geometries in Revit comes in handy ;) <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Greg Collins<o:p></o:p></p><p class=MsoPlainText>GLUMAC | (949) 833-8190<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>-----Original Message-----<o:p></o:p></p><p class=MsoPlainText>From: equest-users-bounces@lists.onebuilding.org [mailto:equest-users-bounces@lists.onebuilding.org] On Behalf Of sambhav tiwari<o:p></o:p></p><p class=MsoPlainText>Sent: Tuesday, May 10, 2011 4:38 AM<o:p></o:p></p><p class=MsoPlainText>To: equest-users@lists.onebuilding.org<o:p></o:p></p><p class=MsoPlainText>Subject: [Equest-users] Exterior Shades<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Hi All,<o:p></o:p></p><p class=MsoPlainText> My Glazing is having exterior shade from all four side it<o:p></o:p></p><p class=MsoPlainText>is like 2 overhangs one at top and other at bottom of glazing and two<o:p></o:p></p><p class=MsoPlainText>side fins. is this any formula to calculate reduction in shgc value<o:p></o:p></p><p class=MsoPlainText>by all four shades as it is just by one overhang.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Thanks<o:p></o:p></p><p class=MsoPlainText>Sambhav<o:p></o:p></p><p class=MsoPlainText>_______________________________________________<o:p></o:p></p><p class=MsoPlainText>Equest-users mailing list<o:p></o:p></p><p class=MsoPlainText>http://lists.onebuilding.org/listinfo.cgi/equest-users-onebuilding.org<o:p></o:p></p><p class=MsoPlainText>To unsubscribe from this mailing list send a blank message to EQUEST-USERS-UNSUBSCRIBE@ONEBUILDING.ORG<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>_______________________________________________<o:p></o:p></p><p class=MsoPlainText>Equest-users mailing list<o:p></o:p></p><p class=MsoPlainText>http://lists.onebuilding.org/listinfo.cgi/equest-users-onebuilding.org<o:p></o:p></p><p class=MsoPlainText>To unsubscribe from this mailing list send a blank message to EQUEST-USERS-UNSUBSCRIBE@ONEBUILDING.ORG<o:p></o:p></p></div></body></html>
