Also, the roof is not attached, it is like a huge "Patio". Thus, air flow will be fresh air from the outside constantly flowing in and out of the stadium. Thus, hot air will not be able to accumulate "inside" because there are no walls to hold it in.
The stadium is also "underground" which keeps it much cooler.
I also get concerned about the "Clear Canopy Cover" but I heard it reflects the heat somehow and it reduces heat, not increase heat like a magnifying glass.
Simply put, it's going to be the World's One Of A Kind Stadium and Entertainment Mecca.
