Never before in my life have I encountered revolving doors so often as in Germany, and every time I have to use one, I wonder what’s exactly the point.
Any ideas? The only think I can think of is that they slow down people on purpose, for crowd control.
Likely also for energy efficiency, but then the double doors system that I’m use to seems more efficient and probably cheaper than revolving doors.

They also keep the heat in

Yeah, that makes sense. It’s the same for where I come from (but keep the cold in, instead), and the airlock system is by far the preferred solution. I think only IKEA insists on revolving doors where I came from.
