LEED Baseline Windows

Hello all,

Thank you to all that have been answering my questions throughout this last
week. You have been a great help.

I am modeling a building for LEED. Once I finish modeling my building as
designed, I need to model compare the model to a baseline building. One of
the baseline building requirements is to have equal window distribution on
all facades. I know that in the wizard, if you know your window %?s that
you can specify a window width of 0 it will create a single long window per
fa?ade. Unfortunately, I used the custom window/door placement & am
planning on taking the plunge into DE mode to polish off my As Designed
building. In DE mode, is there a simple way to model windows in a strip
fashion as LEED baseline buildings require? What is the best way to go
about this?

I pawed through the building-sim archives and there is a lot of hype about
an ASHRAE 90.1 addendum A that gets rid of this requirement to equally
distribute glazing in horizontal bands. From what I read, I don?t think
that LEED accepts this addendum. That being said, I just want to go forward
with modeling the horizontal bands. If somebody knows otherwise for a FACT,
I would appreciate the heads up!

Thanks,

Ryan Lacey

Hi All,

What's the best way to create (or find in the library?) a window for a
LEED Baseline model? I need two, both U=0.57, SHGC=.39 and .49, but
nothing I've found in eQuest even tells me the these values for the
existing windows.

Thanks,

You can use window5 to create your windows to specification, and then
import them into eQuest (at the bottom of the tools menu if my memory
serves me). I personally haven't done this, so I can't speak to how well
it works, but I believe it was mentioned in the initial training I went
through.

Anyone have comments on this?

One of the folders in equest directory is called windows which has an
excel sheet with all the values (u, shgc, etc.) for the equest library
windows. You could pick the one closest, or the windows5 is another way.
