color:#1F497D'>You can model whatever size and shape you want as long as your
area weighted SHGC, and U-value are correct, and your shading is modeling
correctly. Daylighting performance might be affected slightly, along with
passive solar performance, but I am fairly certain that the affect would be
very small compared with the annual building energy use. If you’re genuinely curious,
try it. Model a couple of different scenarios, all with the same total area,
u-value, and SHGC, and see what happens. <o:p></o:p></span></p>

color:#1F497D'>I’m not sure about what LEED requires, but I would be aware that
in addition to Window-Wall Ratio, you should also consider Glass-Frame ratio.
Depending on the software and method that you model windows, two 3’x5’ windows
with a 1” frame are NOT the same as one 6’x5’ window (the 6’x5’ would have two
vertical components, whereas the two 3’x5’ would have four vertical
components). I’m not sure a LEED reviewer would notice the difference, but I
think best practice is to include the correct frame area in your model.</span><o:p></o:p></p>
