History
The park was built during a wave of new, baseball-only parks in the 1990s. Although nearly all of those parks were open-air, it was taken for granted that a domed stadium was a must for a major-league team to be viable in the Phoenix area. Phoenix is by far the hottest major city in North America; the average high temperature during baseball's regular season is , and game-time temperatures well above are common during the summer.

Maricopa County
Maricopa County () is a county in the south-central part of the U.S. state of Arizona. As of the 2020 census the population was 4,420,568, or about 62% of the state's total, making it the fourth-most populous county in the United States and ...
Board of Supervisors approved a 0.25 percent increase in the county sales tax to pay for their portion of the stadium funding. That happened during a huge county budget deficit and lack of funding for other services. The sales tax was very unpopular with local citizens, who were not permitted to vote on funding a baseball stadium with general sales tax revenue (use of public subsidies for stadium projects was prohibited by a 1989 referendum). The issue was so controversial and divisive that, in August 1997, Maricopa County Supervisor Mary Rose Wilcox was shot and injured while leaving a county board meeting by Larry Naman, a homeless man, who attempted to argue in court that her support for the tax justified his attack. In May 1998, Naman was found guilty of attempted first-degree murder.
The cost of the stadium was estimated at $279 million in 1995, but cost overruns, in part because of rising prices for steel and other materials, pushed the cost to $364 million. As part of the stadium deal, the Diamondbacks were responsible for all construction costs over $253 million. The extra expenses, combined with the Diamondbacks and the other expansion franchise, the

Roof and cooling system

Chase Field's roof is opened or closed depending on the game-time temperature. Even with the roof closed, the park's windows allow enough sunlight to play in daylight without overheating the stadium. The roof takes about 4½ minutes to open or close at a cost of $2–$3.
While the ballpark had a grass surface, the roof would be kept open to expose the turf to sunlight. When necessary, it would be closed three hours before game time using two 200-horsepower motors triggered from a control room in the upper deck above left-center field.

The cooling plant, located in a separate building next to the ballpark, freezes water overnight to reduce daytime electricity demand.
Originally, the HVAC system did not cool above row 25 of the upper level, exposing fans in the higher rows to the brunt of Phoenix' oppressive summer heat. Subsequent improvements kept virtually all of the facility in air-conditioned comfort.
Following the introduction of a synthetic playing surface, the roof is kept mostly closed and is opened only on game days when weather permits, greatly reducing the facility's demand on the HVAC system.
