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?
Isn't that wasted energy?

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