Not mentioned in the vestibule section: during winter, many Chicago businesses erect fabric-on-frame vestibules outside their single swinging door.
But apparently it’s hard to get people to actually use the revolving door.
Doesn’t New York have about the same climate and the tall buildings that Chicago has? Why doesn’t New York have as many revolving doors?
As someone who lives in Chicago and visits NYC for work, the average difference may not seem like much (Chicago has an average January low of 18F and NYC has an average January low of 26F), but it certainly feels much different.
Maybe humans just perceive those lower lows more strongly? From my experience, the change from 0F to 15F feels like a lot more noticeable than a change from 30F to 45F.
Interesting, to me, the change from 0F to 15F is almost nothing, but the change between 30F and 45F feels much different, because the air feels different above freezing as opposed to below. This could just be me though.
I’ve got the same thing although in the Netherlands. I prefer it to be either above 10C or below 0C than in between. Maybe because there’s more water in the air while also being cold between 0C and 10C?
I moved from Boston (very similar climate to New York) to Chicago for university, and was shocked by how much colder it was. Of course, them I moved to Minneapolis, and learned what real cold feels like. Ye cats.
Eh you get used to it, we’ve got nothing compared to places like anchorage. The wind is what makes cold cold. -20 with no wind? No problem. 10mph wind? Ok now you got my attention.
When I first moved to NYC I was struck by the prevalence of revolving doors. I figured the reason was just that with so many people coming in and out it was more efficient in terms of the HVAC bill and I never thought of the pressure effect. I don’t know how it compares to Chicago, but I can tell you that NYC definitely has a lot of revolving doors compared to anywhere else I have lived.
Ah, ok. The article seemed to be saying that NYC had hardly any rotating doors:
Minneapolis might be colder and New York may have tall buildings, but Chicago uniquely combines all the important factors.
As someone that lives in the twin cities, there really aren’t that many revolving doors even in the tall buildings. And yes we’re colder than Chicago most of the time. I’m actually hard pressed to come up with a skyscraper in Minneapolis or st paul with revolving doors for the entrance. None jump out at me but I’ll be honest I haven’t paid much attention.
Generally though we tend to have 2 sets of doors on buildings, so that might mitigate the pressure situation somewhat. I’ll have to ask my architect drinking buddy what the deal is. I always heard they reduced the cooling/heating bill more than the pressure situation.
I think you missed a sentence. “Chicago and New York are the biggest markets for revolving doors.”
Though quite a few places in New York don’t have space for revolving doors. They don’t have space for double doors, either. They just hang a curtain inside the door, which is pretty useless.
