The east and west facade, on the left and right ends of this photo, are metal to reflect the sun. The north and south facades are glass, with sail-like shade structures that let light in but keep direct sun out.
There are round skylights on the roof, and on the first day of spring and fall the sun passing directly overhead at noon sends shafts of light down onto pillars in the interior. Crowds gather to watch, sort of like a Phoenix equivalent of the crowds watching the serpent shadows on the side of the staircase of the grand pyramid at Chichen Itza in the Yucatan.
This week we are showing photos of Canadian Thanksgiving on Cape Breton Island, Nova Scotia on our Viva la Voyage travel photo site.
