[LETTERS TO THE EDITOR]Close doors at entrance, save moneyI have enjoyed reading the "About Korea" section on your Web site.
The features "Dig in, Everyone" and "Behind the Mask" are informative.
I have a cultural question. I have noticed that in cold weather many entrance doors to large apartment buildings and office buildings are always open.
There are no mechanisms that force the doors at the entrance to close. The lobbies near the elevators and stairwells are almost as cold as the outdoors. I have noticed, however, that the other doors inside the building have mechanisms that force the doors to close after someone passes through. Is there any cultural reason for this arrangement?
It seems to me that by closing the main entrance doors considerable money could be saved because less heat would be required to warm the building's inner rooms.
