warm air...

A nearby college includes a building, surrounded by an
outdoor arcade, at street level. At one point, the warm
internal air is expelled, which is natural, they perform
continuous circulation. A nice spot, on a cold night!

However, I wonder, is there any hazard in breathing that air?
Is it chemically processed somehow, contaminated?

And, isn\'t it inefficient? The outgoing air ought to
pass through a heat exchanger, to warm the incoming air.
Isn\'t that wasted energy?

possibly it has less oxygen that fresh air, possibly stink and virus
particles?

It might be, it depends if their AC is heating or cooling
