Fri Jan 25 13:22:54 PST 2008

So is the text in addendum "as" incorrect (see below) as it was removed
in "a"?

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!
