Here's the question:
Why do some schools open the windows and doors in the hallways in the winter? My school opens nearly half the windows and doors to the outside even when it is near freezing. This is hard for me to comprehend because a) it's a major waste of heat/energy b) everyone is wearing sandals and c) they are worried about students getting sick, and a cold school is a good way to make students sick.I've always wondered the same. I used to hate being in public schools (or even some hagwons) during winter. There's nothing worse than sitting down on that ice-cold toilet seat. I remember how cold the stairs were in my first hagwon. Brutal.
My best guess is just that, a guess. It wasn't too long ago that many schools in Korea used space-heaters and other styles of old ovens in the classrooms. There was no reason to heat the hallways since students spent most of their time in the classrooms. I guess.
You raised some good points as well. It seems like it's a major waste of energy and you could argue that well, but most of the schools I've been in don't have any heating units in the hallways, so at least the heat isn't pouring out. Of course, the classrooms are connected to the hallways which would certainly reduce the warmth in the classrooms. So yes, it's a waste.
The kids do wear sandals or slippers in most schools and it seems that the cold air in the school could lead to an increase in illnesses. I guess we could assume that this practice is supposed to curb outside germs from getting inside which is highly debatable, but I think it also decreases the need for teams of janitors in schools. Less dirt (which most schools have fields of) on shoes would decrease filth. Regardless of the reasoning for the slippers, I'd like to see some comparative illness stats before assuming that it leads to more sicknesses. It makes sense to me though.
I also think it's perfectly reasonable to assume that a cold, drafty school is a potential health hazard, but I have a feeling that some school officials believe that by leaving the windows open, the bacteria, germs and viruses will be sucked out by or killed by the cold.
Anyone else have any ideas?
