Why do houses have windows?
Houses have windows so that the ventilation is good. Imagine
living in a house with no windows; you wouldn't be able to breathe
properly and would hardly have any fresh air. Another reason is
that light can enter if you have windows. If you have no windows,
your would live in total darkness. It also gives you some light
from the sun and some warmth. A further reason is that you are able
to see outside the house/shelter and to see, for example a postman,
police or maybe even Santa, basically anyone who is knocking on the
door... -_-. Widows are sometimes used as decorations etc.
Honestly, there isn't a real "need" for windows anymore. We keep them because we like them. I, personally, would love it if my bedroom had one whole wall being just windows. When I get a car, big windows will be a must. It's nice to be able to see outside. (: *_*
In Japan they are increasingly designing homes with windows in the ceiling instead of facing outward. In many urban settings looking at the sky is the only pretty view. Although one might view such a home as a way to fight crime, there is no real crime in these neighborhoods.
To let daylight in and to let the residents see out.
a couple reasons, people like the view and when its hot outside you can open a window and so you can get sunlight in on hot days so you wont have to turn on the lights and create even more heat
