Bank of America "green" building

[Prius_Gnome]

I was in a discussion at work about it and I was hoping someone would know more about BofA's "green" building at One Bryant Park (6th Ave and 43rd St) in Manhattan. I already know about its LEED Platinum status and its many "green" attributes but I wanted some clarification about its windows if you guys knew.

1. Does anyone know for sure if the building has a double wall of glass? By that, I meant it looks like a skyscraper encased in another glass sheath. From my office's vantage point, the people walking in its outer hallways seem to be farther away from the windows. For those of you who can't see it in person, check out the photos on:
Bank of America Tower (New York - Wikipedia, the free encyclopedia)
and
Green Towers for New York: from Visionary to Vernacular

The second page of the second link states: "An advanced double-wall system in portions of the facade further conserves energy." And their press release (Bank of America | Newsroom - Press Releases) mentions: "translucent insulating glass in floor-to-ceiling windows". That first quote could be interpreted as extra insulation in the walls or 2 sets of windows. That second quote could be interpreted as double/triple-paned windows or 2 sets of windows. I was hoping someone here would be able to clarify.

2. And if it is 2 sets of windows, how would it help? Do you think the air between the 2 sets of glass would act as insulation? Or perhaps the 2 sets of low-E glass helps dampen temperature variations by reducing radiative heat transfer twice instead of once?

3. I've heard it has BOTH photovoltaic cells AND a green roof? Fact or fiction?

Thanks in advance.
