Freedom Tower Will Be Green Giant

Wired News: t: "The 'skin' of the building will use materials that allow in the maximum amount of sunlight while providing insulation, Battle said. The lobby and other areas of the building are designed to use natural ventilation that reduces the need for electricity, according to Battle."

So that answers my question when I blogged on this a few months back about what else, if anything, was to be done to make the thing greener. In fact, it sounds like quite a good design. Hurrah!
