A couple of questions:
1) How is the water used to cool the floors cooled? I get that underfloor cooling is a viable alternative, but if mechanical chillers are used to provide cold water, it looses quite a bit of its green cred.
2) Is the lack of AC confined to the Olympic Village or does it extend to indoor arenas? With crowds and hard working athletes, indoor air temperature could reach dangerous levels if the summer is hot and humid.
I’ll bet the organizers and other big shots will have air conditioning….
