It's interesting that you mention Gunnar Birkerts. This building has the same massing for the same program as Minneapolis's Reserve building, but Birkerts had also designed an aluminum clad building (the IBM Building in Southfield, Michigan) with triangular sun shades. The sun shades were different though, they were integrated into the facade more and they were part of a bunch of other environment/performance related considerations.

But all together this fine building seems to be a combination of ideas found in those two Birkerts projects.
