Yeah that would be an option, but I would call it 'other measures' rather than roof height, because a roof height is never provided on CTBUH. The issue I am raising is it's very often that we can't decide where the roof is. Take the example you gave, Q1. Where is the roof? Is it at the roof of the topmost inhabitable floor? (just over 200m) Is it at the top of the plant room? (a few above that) Or is it at the top of the decorative glass blades that wrap around the top of the building but in no way constitute a structure? (more like 245m) This is why, if you look at CTBUH for Q1, as with just about every building, they don't include a roof height (http://skyscrapercenter.com/building/q1-tower/399). The roof
