Originally, the Parisians said this would be an AC free Games and they'd be using geothermal to keep the rooms 11 degrees cooler than it was outside (where average high is just 76). But the rich nation's bitched and moaned and got AC last year.
Spokespeople for the committees of Canada, Australia, Brazil, Britain, Italy and Norway told Yahoo Sports that they’d be renting AC for Village apartments. Japan and Greece have also confirmed their AC plans. Canada cited its “commitment to providing optimal health and performance conditions.” An Australian spokesman said: “The reasoning is high performance.”
Thea article doesn't say anything about AC for Kenya, Ugandan or Ethiopian athletes.
