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.
Cheaper is relative. Those double door systems need a lot more space if designed for many people (where you need two or three of those sets side by side), which is expensive.
And as simply someone who wants to enter a public building I prefer revolving doors. More user friendly.
But so slow, that’s what gets me all the time. I like moving fast around town.
