[Equest-users] DD "Exterior Windows"

[Sami, Vikram]

What is the height you've specified? If your height is not enough (the default is 5 ft I think), then you cannot get to the percentages you are specifying without your window being wider than the wall it sits in.

On a side note - that's a LOT of glass :-). If you're doing an ASHRAE comparison your baseline is only going to have 40%.

Subject: [Equest-users] DD "Exterior Windows"

Hello all,

I have a question regarding to the "Exterior Windows".

I calculated window-wall ratio for each orientatioin and floor.

So on the first floor, I have the following window-wall ratio: S-88%, N-69%, E-96%, W-94%, and NE-69%

When I put these inputs, however, it keeps giving me a warning saying "Range Check Error: Value being checked=88. Percent Glass value exceeds maximum (based on the window height and the sizes & positions of other windows).

Could you please tell me how I can fix this issue? Is my calculation method wrong? Plesae provide me some advice.

Thank you so much.
