Baseball in Phoenix in summer? Prepare for news stories about the “frightening heatstroke epidemic”.
Chase Field’s roof is opened or closed depending on the game-time temperature. Even when the roof is closed, the park’s windows allow enough sunlight to play in true daylight without overheating the stadium.
The roof, which takes just 4½ minutes to open or close at a cost of $2–$3, is closed three hours before game time using two 200-horsepower motors triggered from a control room in the upper deck above left-center field.[9] A massive HVAC system then drops the temperature inside the park to about 78 °F (25.5 °C) by the time the gates open. The chilled water system, which has cooling power equivalent to 2,500 homes of 2,000 square feet (190 m2), also serves more than 30 buildings in downtown Phoenix.[9] The cooling plant, located in a separate building right outside the ballpark, freezes water overnight to reduce daytime electricity demand.[9] Originally, the HVAC system didn’t cool above row 25 of the upper level, exposing fans in the higher rows to the brunt of Phoenix’ oppressive summer heat. Changes since then keep virtually all of the facility in air-conditioned comfort.[23]
This stadium has a movable roof. That might help.
The problem I see....you open up the stadium and maybe no fans in the stands would show up for 3 games over eight hours. There’s zero profit for the teams under these circumstances.
To make this work, you’d have to have four (maybe five) stadiums being used like this (maybe in San Diego, Tampa, and Atlanta as well)...with teams only playing ‘grouped’ teams...meaning no travel. Less risk of transmission.
Losing interest around the rest of the US? I think 70-percent of us would shake our heads.
I’ve experienced PHX (and Yuma) in (late) June. Man it’s hot hot hot.
