The building features all kinds of green conscious decisions such as maximizing natural light and using the tower as a giant air filter. One of the coolest (no pun intended) technologies I thought were the manner in which they designed minimizing the amount of air conditioning that is used by actually producing ice during off hours and transitioning that energy to help cool the building.

As the building was being constructed, I couldn’t help but feel a little vertigo from watching the iron-workers construct the 250 foot tall spire while a crane had the pieces suspended over 1000 feet above ground. That’s one profession that amazes me—iron-working. How do those guys do it!?
