You are completely wrong.
Imagine assigning to each floor a whole number.
Every time you go down a floor, the number should be decremented by 1, every time you go up a floor the number should be incremented by 1.
In order to get symmetry, floor 0 should be the ground floor - not floor 1. What maniac would assign floor 0 to the first basement floor?
Yes, but I was talking about assigning numbers from a logical perspective, not a conventional one.
Also, why is it called B1 for the first basement floor but not E1 (for elevated) for the floor above ground floor?
Americans always focus on facades, and think about buildings as commodities. The logic is that in the American conception, each floor is a floor-to-ceiling architectural layer, as viewed from the front of a building. So you think:
B2 - Second layer below visibility B1 - First layer below visibility 1 - First visible layer 2 - Second visible layer 3 - Third visible layer
“How many layers am I paying for, when I buy this building? Sir, If you buy 7 layers at this low, low price. I will throw in an 8th layer for free!” “OMG did you hear Frank’s new house has 4 layers! Frank has way more status than Bob and his paltry two layer building.”
Whereas in most countries, the conception is that a floor is each literal floor you pass as you go up or down while traveling inside a building.
-2 - I’ve descended two floors -1 - I’ve descended one floor 0 - I haven’t gone up or down since I entered this building 1 - I’ve ascended one floor 2 - I’ve ascended two floors
Don’t you see how that’s such an obviously ugly and mathematically unsatisfying retrofit to make your shit work?
B2 B1 1 2 3
vs
-2 -1 0 1 2
And what the hell do you even do in a situation where 0 is at street level but -1 opens on a backyard or something. It’s clearly not a basement, but it’s clearly not the ground floor either.
Or do you never build an elevator in such buildings in order not to trigger massive cognitive dissonance?
EDIT: Holy shit there is another layer to this hypocrisy cake. Americans swear up and down that they have to write “12/11” because they say “12th of September”, but their floor notation is literally “B1” for “First Basement”. Clearly the only rule they follow is that they’ll do whatever is least logical and convenient just to piss off everyone who is forced to work with them.
Main entrance determines the position of the ground floor. If your basement leads to a backyard that leads to another street, it’s just a basement access.
Unless you declare the basement entrance to be the main entrance, then the initial ground level entrance is not on the ground floor anymore. So it’s pretty much up to your discretion how you handle it.
In order to get symmetry, floor 0 should be the ground floor
Floor 0 is “not in the building”, nobody calls first/ground “0” in reality
Then, we apply your own logic of adding a floor on going up to include “going in” and vice versa for “going out” and we get why the US does it the way we do
I don’t get what you’re saying. Why wouldn’t floor 0 be in the building if we started assigning numbers to floors?
0 is nothing, non-existent, etc., so it represents not being in the building, where there is no floor (we call it ground)
It’s the first floor that you encounter of a building, not the zeroeth floor you encounter
Normal human convention is to count physical existing items from 1, I wouldn’t say I’m wearing 0 shirts right now at work for example, or that I’m wearing 1 shoe
