I loved this building, too -- but unfortunately I was not able to have this kind of light to make the copper glow like that. This is the Federal Building, built by the WPA in 1936. Its copper sheathing is a salute the Arizona's one-time claim as the nation's "Copper State." I did make a photo of the sheathing at mid-day, but had to use a different kind of concept to make it work. You can see it in my travel article on Arizona's Route 66 athttp://www.worldisround.com/articles/305763/photo29.html
