Located 
in downtown Phoenix Arizona in the Legends District, the stadium was built to be the home of the Major League Baseball expansion Arizona Diamondbacks.
When it opened it was heralded as a state-of-the-art retractable roof stadium capable of having the roof open and close in just over 4 minutes.
With summer temperatures well over 110 degrees, Major League Baseball insisted on a stadium that could shield the players and fans from the intense heat.
On game days where the outside temperature is below 100 and the sun setting the game will typically be played with the roof open. In case of day games and temperatures over the century mark the roof will remain closed and air conditioning is used to cool off the playing surface and seating areas.
