The way I have always interpreted this is you calculate your window wall
ratios as an average. If its under 40% - your base building has the same
percentage, and if its over 40% your base building has 40%.

Harakhlaal,

It is a good thought but seems like it could end up being a lot more work. I
would have to go with Vikram and say I've only done it with individual
pieces of the geometry not the entire geometry.

I have an added question. When ASHRAE says create a wall with a 40% window
does that mean you have to do it for all walls or only if you are going to
put a window in it. So in other words if you have a wall with no windows in
your proposed does it need a 40% window?

The way I read it is you only need a 40% window in your base if the proposed
has a window percentage higher than 40%. It actually states "40% of proposed
or matching proposed whichever is smaller." (paraphrasing) Am I reading this
correctly?

If you can add a 40% window on a wall that doesn't have one you could pretty
much knock that baby out of the park on performance." 1/4" no insulated
glass window" versus a "R-XX wall with no insolation from the sun on your
floors."

Thanks,

PETER HILLERMANN

I haven't done it with the entire geometry - just individual pieces. It
should work provided you retain the same space names for thermal zone
reference.

Best way to find out is to try it. Let me know how it goes.

this will be an easy question for all the advanced users out there.

as i move my design model from iteration to iteration, instead of getting
the baseline model up to speed, has anyone had any luck with simply saving
the revised design case .inp out as the new baseline and then replacing the
geometry portion of the .inp with previous language, i.e. 40% wwr bands of
glass ... wondering if that causes errors down the line ...
