1. When calculating the dominant portion of a wall, do you include the frame with the glazing or is it only the glazing?
2. When calculating the dominant portion of a wall, it’s from floor to ceiling, but what happens if there isn’t a finished ceiling, therefore the floor joist and all framing is exposed. The calculation is from floor to what height?
Hi Rick,
1. The window frame is generally ignored. The glazing is almost always the vertically dominant portion of the wall.
2. You would have to consider the vertically dominant material to the unfinished ceiling. The 2010 standard does not account for this situation. The BOMA 2017 Office Standard does though by only considering dominant portion to a maximum of 8 feet.
