It looks like they're comparing 4 different glass panels there. It's hard to judge from that photo though as there's sunlight streaming through some of them at odd angles.
Yeh it's still hard to tell from the photos, and sometimes you need more than a couple of windows to truly get a good impression. I was hoping for clear windows however.
doesn't look too bad, i guess we were all expecting a totally sleek and different version becausem of the renders...but looks like it's going to be a modern box with standard cladding...eh, will still look cool so i got no complaints.
The City is pushing for more non-reflective windows on towers due to FLAP (birds hitting windows)... I would expect more office projects in the future to have semi-transparent windows that resemble residential projects.
