[Bldg-sim] Appendix G - Base Case Orientations and Glazing

[Paul Riemer]

I read Table G3.1 section 5 sub item (c) under the baseline building performance column to require use of the "SHGC_all" for all vertical glazing.  Have others read that and reached a different conclusion?  Did I miss an addenda? or a CIR?

Dear Ulrik,

Since the intent of the Standard is to assign the better glazing performance to non-North walls, I always rotate the glazing characteristics with the building. (e.g., I assign the "North" glazing characteristics to the elevation that, after rotating, faces North)

Dear all,

When you are rotating the building through 4 different orientations, do you change the glazing so that the glazing with the highest SHGC is always faces north, or do you put the glazing with high SHGC on the original north facade, and then rotate the building so that the high SHGC glazing faces the east, south and west orientations in subsequent simulations?

Yours faithfully,
