horizontal bands are no longer required. You can place the windows =
as-designed and run the baseline with the same windows (as long as you =
do not exceed 40% window-to-wall ratio).=20

Subject: [bldg-sim] eQUEST window baseline
Hello,
I am creating an energy model for a LEED project. In "baselining" the =
building, one of the stipulations of ASHRAE 90.1 2004 is that the =
windows must be evenly distributed in horizontal bands on each facet of =
the facade. My building has 17 facets due to a somewhat complicated =
design and I am wondering if anyone knows a relatively straightforward =
way to accomplish that distribution. One of my problems is that in the =
Design Development Wizard, there are only 4 areas in which to enter =
percentages (N., E., S., W.) which doesn't seem to work on a building =
with so many facets. On the other hand, it seems tedious to go into =
each window and adjust its percentage. Is there a more elegant way to =
adjust window proportions globally? I am thinking a parametric run =
might be the best solution. Can anyone provide some insight on this?
Thank you!
Andrew McNamara
