I think the dark glass and white mullion/spandrel combo was a bad choice.
A lighter aqua glass tint would have actually suited the white mullions and aqua spandrel more, and not looked so garish.
In order for this black glass to work, it would need black or bronze spandrel and mullions.
This could have been achieved without spending more on the actual materials, just making sure that the colors ordered matched.
I don't think this city has a 'green glass' problem at all. We have an haphazard/mismatched mullion/spandrel problem. It boggles my mind how developers act as if they dont have the time to get this right, when the city endlessly delays approvals for projects.
