The United States Courthouse in Phoenix, Arizona is named after Sandra Day O’Conner, the first woman to be appointed to the Supreme Court. It was constructed from 1994-2000 at a cost of 123 million dollars, and the six-floor building has a floor area of 555,000 square feet. Sandra Day O’Conner United States Courthouse uses glass extensively throughout different sections of the building. The courthouse features a massive glass wall along the north side of the building, and the main courtroom features an incredible glass ceiling. The courthouse also advertises that it is cooled passively by natural convection, but those on the top floors during the summer have reported extreme temperatures. According to some, the upper part of the building behind the glass wall can reach up to 100 degrees at most.
