[Bldg-sim] FW: [BLDG-SIM] 90.1-2004 Appendix G Glazing for Baseline case

[Zoeteman, Mark R.]

I've reviewed all the 90.1-2004 addenda and don't see where vertical
fenestration requirement of "distributing uniformly in horizontal bands
across the four orientations" has been removed. Addenda "as" which
refers to this section doesn't remove either.

The requirement to  distribute fenestration uniformly in horizontal
bands across the four orientations has been removed from Appendix G in
the published Addenda Supplement to 90.1, 2004. See the ASHRAE website
for the supplement.

Appendix G notes that for the Baseline building: "Vertical fenestration
areas for new buildings and additions shall equal that in the proposed
design or 40% of gross above grade wall area, whichever is smaller, and
shall be distributed uniformly in horizontal bands across the four
orientations."
Does this mean that the Baseline building gets windows on all walls on
each orientation whether or not the Design case has a window in all
walls on each orientation.  For example, if the west orientation has 30%
glazing overall but many spaces have no windows - some walls on the west
face have more that 30%.  Do those spaces in the Baseline case get 30%
glazing?  Or do I only put windows in the Baseline case where there are
windows in the Design case.

Thanks for any help!
