Cold!

This is what I see every morning when I wake up

I think I already mentioned that it is very cold in our Kaikan. I am freezing all the time! The windows are only single glazed (einfach verglast), so the coldness from outside easily creeps into our rooms. And the winter months in Oita can get really cold.
Actually I noticed something funny the other day. I opened my window (completely) in order to let fresh air move quickly into my room for some minutes (Stoßlüften) and went back to studying at my desk. One hour later I suddenly realized that I had not closed the window. So for the room temperature, it had made no difference if the window had been opened or closed. It does not make any difference if I have windows or not! Haha. :(
There is a double phenomenon going on: single glazed buildings and excessive use of heater blowers (Heizlüfter).
On the one hand, the bad insulation makes it impossible to keep warmth in buildings. On the other hand, it makes much heating necessary. But the heating is mainly done by using heater blowers. And on top of that, when heater blowers are used, then they are used excessively!
Exampe: Our whole university is single glazed. The classrooms are extremely cold in the morning. The teacher immediately turns on the big heater blower, which is installed at the ceiling above our heads. The heater blower runs on full speed all the time. After class the heat does not stay in the room, so for the next class it is turned on again. Not only is this method a waste of enery, but also the air is very dry. The eyes dry out, it is hard to concentrate, and in the worst case you get a headache.
Nobody seems to know anything beside heater blowers. The same applies to public transportation and department stores: they are excessively heated with heater blowers. But not only until a moderately warm temperature is reached, but until you feel like taking all your clothes off the minute that you step into the room, bus or train. It is so hot! It is such a waste of energy. And it is unhealthy.
I do not want to close my post on such a negative note. But I do not know what to add to make it sound like fun.
