We have "aircon" wars over here in Romania, too. I'm now working from home but in the previous ~15 years of me working from an office one of the major stresses while moving in with new office colleagues was "will we be able to not kill each other in the summer over how the AC should work?" (I'm exaggerating, but only by a bit).
We also have what we call "curent" which is translated to "draft". There are many online articles about how foreigners view our (Romanians') obsession with "curent", this [1] is just one of them.

You see more people investing in double glazed windows like they do in Europe. I've done this to my house and it works really well against both heat, cold and sound. Combined with an efficient fireplace, you can enjoy a toasty winter in the cold winter evenings.
EDIT: Okay well of course it should be as this is what you have done already. So, maybe what I am asking is how complicated is the process...
I have yet to experience an aircon war in Germany, but there is also a pattern where men want to open a window to keep the air fresh, while women find it too chilly and want to turn on a radiator instead (of course there are exceptions).
I can't get much done in radiator air, so that's one more reason to work from home, or in well-matched office rooms.
This tends to happen a lot in environments where business attire is a must. It's harder to find a good compromise when some people wear business suit and tie and some wear skirts or open shoulders. And that's even before you factor in possible physiological factors (people have different comfort zones).
If you've got menopausal women that's a problem too, and I think perhaps women and men just have different temperature preference distributions.
My kids teachers (all female) refuse to let the boys wear shorts except in Summer term because the teachers consider it not to be warm enough .. but they wear skirts and dresses all year .. which is weird.
Established norms on dress and room heating/cooling are pretty arbitrary I feel.
I bundled all that under "physiological factors". There are also sociocultural factors at play but that's a minefield of a discussion. It's how gender stereotypes are born and educated into kids from a young age.
A guy once told me that they install thermostats in corporate buildings that are actually disconnected from the system because people complain less if they can see thermostats in the room.
Basically, in the winter, we need to wear jackets while sitting at our desks in a place like JHB simply because the ventilation for some reason is pretty cold. I've heard that in European businesses you take off all your warm clothes indoors and just wear a T-shirt or other shirt.
There is also what we call it the "aircon" war. Usually black people (and myself) want the aircon off, but white people want it on. This is a joke though so don't take it too seriously (or racially). But this is mostly about when the aircon is cooling the building. When it is supposed to heat the building in a colder region most people will agree that the rooms are too cold, but for some reason we can't seem to learn this lesson.
By the way, for the sake of interest, Jan Smuts was well known for having a house with very cold winters and very hot summers. It is said that his guests would often comment on this when they stayed over. [1]
