1. A triple glazing unit comprising:
a first pane;
a second pane;
a third pane between the first pane and the second pane;
an electrochromic device coupled to the third pane and between the third pane and the second pane;
a first cavity between the first pane and the third pane; and
a second cavity between the second pane and the third pane, wherein a size of the first cavity is different from a size of the second cavity, wherein the first cavity comprises about 100% atmospheric air and the second space comprises 90% argon or krypton and 10% atmospheric air, wherein the triple glazing unit has a solar heat gain coefficient in a clear state between 0.2 and 0.4.
