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.
I see. Then it might be a factor of population density. Where I come from, there’s way less people moving in and out per building, to put it simply.
That solves it for me.
