[Equest-users] Exterior Shades

Little-known (?) factoid that may help:  

 

In detailed mode after wizards, you can define a "setback" for one or
any # of windows.  This achieves 4-sided shading for both the window and
frame, as you're describing ;).  I don't think this shows up I the 3D
view, but it could be my current project is just acting wonky.

 

 

 

PS:  Bill, I think you may be a little off on your rooftop unit
dimensions there... let's not set a sloppy example ^_^ (j/k)!  Awesome
as usual!

Sabmhav,

 

I find that the overhang and left/right fins allowed for each window
take care of most of shading I encounter. You can use building shades
for anything else. Building shades might even make more sense if you
have a single continuous overhang that shades several windows, or if the
shade is non-opaque.

 

  

 

Regards,

Bill

There is no standard formula for doing this.  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.  

 

This is when modeling geometries in Revit comes in handy ;)

Hi All,

           My Glazing is having exterior shade from all four side it

is like 2 overhangs one at top and other at bottom of glazing and two

side  fins. is this any formula to calculate reduction in shgc value

by all four shades as it is just by one  overhang.

 

 

Thanks

Sambhav
