Zamboni & Ice Refrigeration???

I'm looking into remodeling our school's old fieldhouse into an on-campus ice arena.

Can anyone tell me the pros or cons of propane powered zambonis compared to battery? At first I thought it was obvious. Propane gives off exhaust which might cause 3rd period headaches. Whereas electric engines are clean. But if that's the case, I'm wondering why all of the biggest, newest rinks in the state of MN (Xcel, Midwest Wireless, Mariucci, Engelstad) happen to use propane resurfacers? Is it simply that there's more than enough room for the exhaust to fan out?

Also, what's the difference between direct and indirect ice refrigeration? Again, my first impression was that indirect basically meant that the whole arena was freezing cold. But again, many of the bigger rinks (including Xcel) use indirect refrigeration. This is all according to rinkfinder.com. Basically, my question is why do you have to wear a coat and 4 layers of sweatshirts to some high school and college arenas, while you can be comfortable in others with just a sweatshirt?

Are there any NHL arenas around the league that are notoriously cold?

Thanks in advance.
